1.1 OPERATING/MAINTENANCE SAFETY (08/03/25) 1-01-001

1.1 Operating/Maintenance Safety

When operating this machine, the safety of the operating crew and other workers in the area must be the principal concern. All persons operating this machine must understand the necessary safety precautions to help minimize the risk of accidents and injury. The operator must ensure that all fire fighting equipment is in working order, inspect the condition of all walkways, handrails, ladders, and guards.

Personal Protection Equipment

All safety equipment such as hardhat, steel cap boots, safety goggles, hearing protection, gloves, etc., should be worn while operating this machine.

Snug fitting clothing should be worn by the operator in and around the drill so as not to be caught up in any moving machinery.

Overhead and Buried Utilities

Special precautions must be taken by everyone when using a drill rig in the vicinity of electrical power lines and other utilities. Underground electricity is as dangerous as overhead electricity. Be aware and always suspect the existence of underground utilities such as electrical power, gas, petroleum, telephone, sewer, and water.

Electricity can shock, burn, and cause death.

• Overhead and buried utilities should be located, noted, and emphasized on all hole-boring location plans and hole-boring assignment sheets.

• When overhead electrical power lines exist at or near a drilling site or project, consider all wires to be live and dangerous.

• Watch for sagging power lines before entering a site. Do not lift power lines to gain entrance.

• Before raising the drill rig mast on a site in the vicinity of power lines, walk completely around the drill rig. Determine what the minimum distance from any point on the drill rig to the nearest power line will be when the mast is raised and/or being raised. Do not raise the mast or operate the drill rig within a minimum of three (3) meters of any electrical power line or other obstruction.

• Only move the drill rig with the mast down.

If there are any questions concerning the safety of drilling on sites in the vicinity of overhead power lines, call your supervisor.


Ask for Assistance

If a sign warning of underground utilities is located on a site boundary, do not assume that underground utilities are located on or near the boundary or property line under the sign; call the foreman and check it out. The underground utilities may be a considerable distance away from the warning sign.

Always contact the foreman before drilling. Determine jointly, with utility personnel, the precise location of underground utility lines. Mark and flag the location.


1.1.1 Drill Operation and Maintenance Safety

Read all safety instructions provided here and those provided in the Operator’s Manual before operating and servicing the drill. General safety and accident prevention regulations laid down by local authorities must also be followed.

4.5 TOP DRIVE (08/03/25) 4-05-001

4.5 Top Drive

PM Tasks

The top drive requires minimal maintenance; however, certain precautions must be taken to ensure long life of the unit. The top drive is exposed to severe vibration and shock loading. The frequency of rebuilding the top drive assembly depends on the drilling conditions as well as maintenance of the unit.

It is essential to check the preload of the bearings after the first 50 hours of service as well as every 250 service hours, adjusting as required. This will prevent movement of the driveshaft when the bearings have excessive play. The movement will damage the oil seals and possibly damage the driveshaft wear sleeve and seal housings, causing loss of oil and eventual failure of the top drive.

NOTE: A special tool is required to check the bearing pre-load. Order the tool from

Cubex or manufacture it from an old drill pipe (see Fig 4.5.1.a).

Daily: • Check oil level

• Check for oil leaks

250 Hour Intervals: • Bearing Pre-load Adjustment

• Change gear oil

1000 Hour Intervals: • Torque bolts on rotation motors

• Torque bolts at mounting plate

2000 Hour Intervals: • Inspect top drive and rebuild as required

WARNING!

Disconnect electrical power, mine air, water supply and relieve pressure in air receiver before servicing.

Support mast before removing or loosening hydraulic components or fittings.

4.5 TOP DRIVE (08/03/25) 4-05-003

4.5.1 Checking Bearing Pre-load

NOTE: This procedure is for Preventative Maintenance.

A special tool is required to check the bearing pre-load. Order the tool from Cubex or manufacture it from an old drill pipe (see Fig 4.5.1.a).

It is critical to maintain the correct pre-load on the drive shaft bearings. The test is to determine the force required to rotate the driveshaft. The pre-load is adjusted by removing shims, installed under the bearing cap.

1. Move top drive to a comfortable working position and drain oil. Rotate mast until

top drive motors are facing down.

WARNING!

Secure full load of mast and top drive.

Disconnect electrical power, mine air, water supply and relieve pressure in air receiver before proceeding.

2. Remove top drive motors and cap hydraulic lines.

3. Install Pre-load Checking Tool into drive shaft sub. Place torque wrench on nut, and measure torque required to rotate drive shaft. Torque must be between 65-75 ft-lbs (88-102 N-m).

NOTE: If pre-load is within limits, remove Pre-load Checking Tool and reassemble top drive. Otherwise proceed with Adjusting Bearing Pre-load.

4.5.1.1 Alternative Field Method for Checking Pre-load

1. Move the top drive to a comfortable working position and drain the oil.

2. Install the Preload Checking Tool into the driveshaft saver sub. Using a torque wrench rotate the driveshaft and read the torque required to turn it. Torque must be between 100-110 ft-lbs (136-150 N-m) rolling torque (torque must be read while turning the driveshaft).

NOTE: If the preload is within limits, remove the Pre Load Checking Tool.

Otherwise, proceed with Adjusting Bearing Preload.

4.5 TOP DRIVE (08/03/25) 4-05-004

4.5.2 Adjusting Bearing Pre-load

Normal wear tends to reduce the pre-load. Shims, placed under the bearing cap, must be removed to compensate for wear. The shims are available in 2 sizes - 0.005” (0.127 mm) - clear and 0.010” (0.254 mm) – white, with both being found under the cap.

NOTE: This procedure is continued from "Checking Bearing Pre-load"; therefore the air pressure is already relieved.

1. Remove bearing cap. Remove one shim, bolt bearing cap back in place and torque bolts (30) to 375 ft-lbs (508 N-m). Turn driveshaft two full revolutions.

NOTE: When removing the bearing cap, care must be taken to insure that there are no burrs on the wear sleeve that might damage the seal as the cap is being removed.

2. Recheck bearing pre-load by measuring rotation torque. Repeat step 1 and

recheck bearing pre-load until correct torque is achieved.

3. Remove Pre-load Checking Tool. Reassemble top drive and reconnect power.

Rotate mast until air swivel is up, and check oil level in top drive.

4.5.3 Removing Top Drive

The top drive can be removed with the mast in the horizontal or vertical position.

1. Break saver sub before removing top drive from mast. To break and install saver

sub, follow the instructions given in Section 4.5.10.

4.5 TOP DRIVE (08/03/25) 4-05-015

4. Use the torque wrench on the ¾” bolt installed on the splined piston to check the rolling torque; this is the correct way to measure preload on the bearings, of the driveshaft (see Fig 4.5.25). The correct rolling torque is 75-85 ft-lbs (102-116 N-m). Tightening of the bottom bearing cap bolts will increase the bearing preload and the rolling torque. Once the correct rolling torque is achieved, use feeler gauges to check the clearance between the bearing cap and the gear housing in three places. Use an average of these readings and subtract 0.005” (0.127 mm).

Fig 4.5.25

5. Remove the bearing cap and insert the correct amount of shims under the cap (see Fig 4.5.26). Reinstall the cap and tighten the bolts to 375 ft-lbs (512 N-m) dry torque. Recheck the rolling torque and insure the proper torque value is obtained.

NOTE: Shims in the kit are either 0.005” (0.127mm) clear or 0.010” (0.254mm) white.

4.6 TOP DRIVE MOTOR (08/03/25) 4-06-003

4.6.1 Dismantling Top Drive Motor

Remove the top drive motors from the top drive assembly, plug the hose fittings, and proceed as outlined below.

Refer to Fig 4.6.1

1. Clean the outside of the motor and drain the fluid. Clean all parts, except seals, in petroleum-based solvent, then dry them with compressed air. Keep parts separate to avoid nicks and burrs.

2. Place motor in a vise with coupling shaft facing down and jaws gripping housing

flange.

3. Draw an alignment mark down the outside of the motor from cover (2) to

housing (18) to assist orientation when assembling the unit.

4. Remove bolts (1), end cover (2) and seal ring (4). Discard seal ring. Inspect end cover (2) for operating conditions. A polished pattern is normal wear created by commutator assembly.

Discoloring indicates excessive fluid temperature, thermal shock or extreme speeds. If discoloring exists, inspect items 2, 5, and 8 for scoring or distortion.

5. Remove commutator ring (6) and inspect it for cracks or burrs.

6. Remove commutator (5). Remove seal from commutator, using an air hose blowing air into the ring groove until the seal (3) is lifted out. The seal (3) must be discarded after removal.

NOTE: Item 5 and commutator ring (6) are sold as matched sets.

7. Remove manifold (7) and inspect it for cracks or surface scoring. Replace it if required. A polished pattern on the ground surfaces from commutator or rotor rotation is normal. Remove and discard seal rings (4) from both sides.

NOTE: The manifold is constructed of bonded plates and cannot be dismantled any further. Compare configuration of both sides of the manifold to ensure that the same surface is reassembled against the rotor set.

8. Remove rotor set (8) and wear plate (9) together, keeping rotor set in its assembled form. Then, mark the position to allow installation in the same location. Keeping the original position increases the service life of the torque motor. Remove and discard seal ring between item 9 and item 8.

NOTE: Some motors may have a rotor set with two stator halves with a seal ring (4) between them and two sets of vanes. Discard the seal ring if the stator halves become disassembled.

4.6 TOP DRIVE MOTOR (08/03/25) 4-06-004

9. Check rotor vane clearance as follows: Place the rotor set (8) and wear plate (9) on a flat surface then rotate the rotor as illustrated in Fig 4.6.2. Measure the clearance between the vane and rotor lobe. Replace the rotor set if the clearance is more than 0.005" (0.13 mm). If this motor is equipped with two sets of stators, repeat above procedure on other side.

10. Inspect drive link (10) for damaged splined. No noticeable lash should be

apparent between mating spline parts.

11. Remove seal ring (4) from item 18. Remove thrust bearing (11) from coupling

shaft (12) and inspect it for wear.

12. Remove coupling shaft (12) and check it for wear. Replace it if the two

diameters show wear in excess of 0.020” (0.51 mm).

13. Remove inner thrust bearing (13) to inspect condition. Remove item 16 and

item 17. Remove seal (20) using a seal puller.

14. Remove bearing (19) using a suitable bearing puller.

4.6.2 Assembly Procedure

1. Reassemble in reverse order including the additional steps below.

2. Pack bearing (19) with grease as it is not lubricated with hydraulic fluid.

3. Apply grease to all seal rings (4). Install two studs that are 0.50” (13 mm) longer

than bolts (1) into item 18 to guide external parts during installation.

4. Install bolts (1) and torque to 24 ft-lbs (32 N-m).

5.2 Hydraulic Circuits

An open-loop, hydraulic system is used with a variable displacement, pressure compensating supply pump. The load sensing function strokes the pump up when flow is required, and destrokes when the system is idle.

PM Tasks

The hydraulic system requires limited maintenance. The filter elements and hydraulic fluid must be replaced at the recommended intervals.

Keep all cylinders, motors and valves clean. The cylinder rods are the main source where contamination may enter into the hydraulic system. Replace damaged components immediately. Investigate all leaks, using extreme caution. Worn or damaged hoses must be replaced without delay.

All maintenance should be performed in a clean, well-lit work area. Extreme cleanliness is required when servicing hydraulic components.

250 Hour Intervals: • See Section 5.6 Hydraulic Filtration. Inspect system for leaks.

1000 Hour Intervals: • Change hydraulic fluid.

WARNING!

High pressure oil leaks may cause injury. Use extreme caution and proper protective gear when investigating hydraulic leaks.

After installing hydraulic components and hoses, check that hydraulic actuators are operating in direction as indicated on controls.

2. Standby Pressure: Located on the pump’s control valve, this is the minimum pressure when the pump is running idle.

3. Relief Valve: Located on the inlet cover in each valve bank, except the drilling valve.

4. Valve Pressure: Located in specified valve section, allowing independent settings for both valve ports.

5. Valve Flow: Located in each valve section, allows independent settings for both valve ports. See Section 5.5 Control Valves for individual pressure and flow settings.

5.3 HYDRAULIC PUMP (08/03/25) 5-03-001

5.3 Hydraulic Pump

This model of pump is designed for open-loop, closed center, or load-sensing hydraulic systems. Flow is proportional to the drive speed and the displacement. By adjusting the position of the swashplate, it is possible to smoothly vary the flow.

The “Load Sense” type of control registers the load at a point away from the pump. In the case of your Cubex drill, a pilot line from the hydraulic control valves sends the pressure signal back to the pump. The pump control then tries to keep the output pressure above the load requirements by the standby or differential pressure (pressure compensation). The differential pressure is generally in the area of 400 psi.

Principals of Operation

The displacement mechanism of this series of pumps operates via two stroking pistons (large and small) which adjust the position of the swashplate. The smaller of the two stroking pistons (1) works in conjunction with its spring (2) to always try to move the swashplate to maximum angle, and therefore the pump to maximum displacement. High pressure oil is continually routed from the outlet (pressure) port to the small stroking piston via the control oil drilling (3). Working in opposition to this on the opposite of the swashplate is the larger stroking piston (4). If pressurized fluid is routed to the larger stroking piston (4), it will exert a force to de-stroke the pump to a lower displacement value. Since piston (4) has a larger area than piston (1), the pump will de-stroke with pressure on both cylinders. It is therefore possible to control the pump displacement by changing the pressure applied to the larger of the two stroking pistons. All the pump controls work on the same principal of controlling the pressure on this large stroking piston (4) in order to vary the pump’s displacement.

Fig 5.3.1 Hydraulic Pump

5.3 HYDRAULIC PUMP (08/03/25) 5-03-002

CAUTION!

Rebuilding hydraulic pump is recommended for qualified maintenance technicians only.

When reinstalling pump, ensure that pump housing is filled with hydraulic fluid before starting.

5.3.1 Installation

5.3.1.1 Pre Start-up

1. When you are installing a new pump because of a failure or gradual decrease in performance, it is important that you change the pressure and return elements in the system. The entire hydraulic system requires flushing and installation of new hydraulic oil.

2. Be sure the hydraulic oil level in the tank is sufficient.

3. Remove the case drain fitting and fill the case with clean hydraulic oil. Reconnect the line when full.

4. Loosen the suction line at the pump to allow air to bleed from the line. When oil starts to run out, reconnect the line.

5. Place a 4000 psi gauge at the pump outlet for testing.

5.3.1.2 Start-up

1. With a wrench, remove the protective nuts (see Fig 5.3.2) from the set screws for the differential pressure and compensator control adjusters. Loosen the jam nuts and unscrew both adjustments until you no longer feel any resistance from the control springs. Be sure not to screw them all the way out. This will allow the pump to start at minimum pressure.

2. If the pump is diesel driven, very slightly loosen off the outlet pressure hose or a downstream hose connection. Bump the starter for 2 to 3 second periods to allow air to escape from the line and pump cavity. When oil starts to leak at the connection you loosened, retighten the fittings.

3. If the pump is driven with an electric motor, jog the starter for the motor and follow the same procedure as described for a diesel motor. After you tighten the fitting you used to bleed out the air, run the electric motor. If the pump is noisy, “crack” the fitting again to bleed of the air. Air is probably still in the suction line or pump.

4. Once the pump runs quiet, adjust the differential (standby) pressure setscrew clockwise until the pressure on the outlet of the pump is at the required standby pressure. Once you have set the pressure, lock the jam nut and replace the protective nut on the differential pressure adjustment.

5.3 HYDRAULIC PUMP (08/03/25) 5-03-003

5. Next, set the compensator control adjustment to the recommended setting. To achieve this, you will have to bottom out a control at the valve bank where the load sense pilot line was connected. This is done to provide a signal back to the pump to determine a setting for the compensator. Once the compensator is set, tighten the jam nut and replace the protective nut.

5.3.2 Adjustments

5.3.2.1 System (Operating) Pressure Adjustment

The system pressure is set at the pump’s control valve, mounted at the rear of the pump. If the drill is not equipped with a system pressure gauge, connect a gauge on the inlet side of the pressure filter. Install a T-fitting and cap the line if the gauge is to be removed later.

1. Remove the protective cap and loosen the locknut on the system pressure

adjustment. Check that personnel are away from the drill and start pump.

2. Set pressure to 4000 psi (278 bar) by turning the setscrew with a 4 mm allen key. Turn it counter-clockwise to reduce pressure. One turn creates a pressure change of approximately 725 psi (50 bar).

3. Reinstall the protective cap and torque to 15 ft-lbs (21 N-m).

5.3.2.2 Stand-by Pressure Adjustment

The stand-by pressure is the minimum pressure maintained during zero pump load. It is set at the control valve mounted at the rear of the pump.

1. Install pressure gauge on inlet side of pressure filter.

2. Remove the protective cap and loosen the locknut on the stand-by pressure

adjustment. Check that personnel are away from the drill and start pump.

3. Set pressure to 400 psi (27.6 bar) by turning the setscrew.

4. Reinstall the protective cap and torque to 6 ft-lbs (8.1 N-m).

5.3 HYDRAULIC PUMP (08/03/25) 5-03-005

5.3.3 Testing the Pump

The condition of a pump can be determined by checking the flow.

Install a flow meter in series with a restrictor valve on the discharge line of the pump (make sure the restrictor valve is large enough to handle the flow from the pump). Run this line back to the tank. Make sure the load sense line is included in the circuit.

While the pump is running, slowly restrict the flow with the valve you installed. As the flow is restricted, it should actually increase due to the load sense of the pump. The flow increase should continue until the pressure reaches 80 to 90 percent of the compensator pressure. At this point, the flow will drop off as the pressure reaches 100 percent of the compensator pressure, at which point the flow will be zero. See Table 5.3.A to determine the expected flow from your pump at 1750 rpm.

Fig 5.3.3 Test Circuit

Pump Size Acceptable Pump Flow

71 cc 27.5 to 31 gpm

100 cc 39 to 44 gpm

Restrictor Valve Flow Meter

Load Sense Line

Return back to tank

5.3 HYDRAULIC PUMP (08/03/25) 5-03-006

The approximate condition of a pump can also be determined by the flow produced from the case drain. No more than 10 to 12 percent of the pump output should be coming from the case drain. This means at a speed of 1750 rpm, the case drains contained in Table 5.3.B should apply.

Pump Size Acceptable Pump Flow

71 cc 27.5 to 31 gpm

100 cc 39 to 44 gpm

Table 5.3.B

NOTE: For a case drain leakage test, it is recommended that you DO NOT use a flow meter. This is because piston pumps are very sensitive to case drain pressure. Using a flow meter in most cases causes a certain back pressure that could damage the pump. Instead, use the manual method of directing the case drain into a pail of known volume while measuring the time and calculating the flow.

5.3 HYDRAULIC PUMP (08/03/25) 5-03-007

5.3.4 Troubleshooting the Pump

Problem Cause Explanation Corrective Action

Hydraulic system is not performing as it should. For example the drill has lost performance.

Standby pressure is set too low.

A low standby pressure setting will cause the pump to destroke too soon, preventing the required flow from reaching the hydraulic system.

Check the differential pressure setting.

Pump is bypassing. The pump has been contaminated, cavitated, aerated, or otherwise worn.

Check the pump’s condition. If the pump does not pass standards, replace.

Loss of load sense signal.

The load sense line has become disconnected or obstructed and the signal is not getting back for the pump to compensate.

Check the load sense line for leakage at fitting, breakage, or an obstruction.

The case drain of the pump generates excessive heat.

Pump is worn. If the pump is contaminated, its efficiency will deteriorate and manifest itself as a case drain leak.

Check the acceptable pump performance as outlined in Section 5. Change pump out as necessary.

Pump is noisy. Pump is cavitating / aerating.

If a piston pump is being starved of oil or has air trapped in the oil (aeration), it will sound noisy when running.

Shut the system down.

Make certain the inlet to the pump is not restricted.

Make certain there are no kinks, twists, or obstructions in the suction line.

5.3 HYDRAULIC PUMP (08/03/25) 5-03-008

5.3.5 Factors Affecting the Pump’s Life

The weak link of swashplate piston pumps is the slipper pad arrangement and there are a number of conditions that may detrimentally affect the life of the pump by damage in this area. Essentially there are five possible conditions which may contribute to a failure in this area. These conditions are contaminated fluid, too high a vacuum at the pump’s inlet, excessive case pressure, too low of an operating pressure, and aeration/cavitation.

5.3.5.1 Contaminated Fluid

Besides the obvious accelerated wear caused by contaminated fluid, in extreme cases contaminants can also plug the lubrication passages in the piston/slipper pad area. The principle of the slipper pad design is that the hydraulic force, which pushes the piston towards the swashplate is counteracted by a pressure force acting in the opposite direction. High-pressure oil in the piston chamber is routed via a drilling through the piston knuckle and slipper pad to a recess between the slipper and swashplate. This area is designed to have an effective area, which precisely balances the pressure forces caused by the piston.

Fig 5.3.4 Contamination

The relatively small drillings keep the leakage low and the volumetric efficiency in the pump high. If the system has a high level of contamination, it is possible that these drillings can become plugged. This would lead to an accelerated failure of the slipper pad since both lubrication and balancing forces would be lost.

3. Which causes slipper pad failure.

1. If this passage becomes plugged with contamination…

2. Lubrication and hydrostatic balancing are lost here…

5.3 HYDRAULIC PUMP (08/03/25) 5-03-009

5.3.5.2 Too High of Vacuum Condition

The piston/slipper assemblies are connected together via a crimp connection. This type of connection is excellent under compression but cannot stand high tensile forces. During the suction process, the piston is drawn back out of the bore because of the retaining plate pulling on the slipper pad. If the vacuum at the pump’s inlet is too high, it will oppose this motion and the tensile force will increase to a point where two modes of failure occur.

1. The retaining plate flexes and allows the slipper to lose contact with the swashplate. On the pressure side of the pump’s rotation, the slipper is once again brought to contact as the high-pressure oil forces the piston back. At this point, the slipper is damaged due to rounding of the slipper corners from uneven re-seating contact. Repetition of this process will damage the slipper to a point where it can no longer retain its lubricating pool of oil and the pump will fail.

2. The high vacuum forces the slipper pad to simply be pulled off the piston knuckle if the tensile strength of the connection is overcome.

CAUTION!

Unfortunately, it is difficult to detect this failure by listening to the operation of the pump and the pump will keep running until it is destroyed.

Fig 5.3.5 Too High of Vacuum Condition

3. Will cause slipper pad lift-off and slipper/piston serration.

1. Too much vacuum here…

2. Or too high a case pressure here…

5.3 HYDRAULIC PUMP (08/03/25) 5-03-010

5.3.5.3 Excessive Case Pressure

Excessive case pressure has the same effect on the piston/slipper assembly as the too high of vacuum condition. As can be seen in Fig 5.3.6, the two areas actually work together to force the piston to the left, causing a high tensile force in the piston/slipper connection. Because of this, a marginal suction condition and a marginal case pressure condition may work together to cause a failure of this type.

Fig 5.3.6 Excessive Case Pressure

In order to avoid damage by either of these two conditions, the suction line and drain line should be optimized. This means that the pump should always have a flooded suction (mounted below the oil reservoir oil level) and there should be limited resistance in the suction line itself. Therefore, the amount of bends should be minimized and only full area shut-off valves should be used if required. The case drain should be full sized and as short as possible back to the reservoir. It is not advisable to tee the case drain line in with any other return lines and each pump case should be routed individually back to the reservoir.

5.3 HYDRAULIC PUMP (08/03/25) 5-03-011

5.3.5.4 Too Low an Operating Pressure

The running area between the slipper pad and the swashplate relies on high pressure oil for lubrication. If the pressure at the outlet of the pump is too low (i.e. the pump outlet is unloaded to tank), excessive wear will occur in this area causing premature pump failure.

5.3.5.5 Cavitation/Aeration

Cavitation results when air, which is typically entrained or dissolved in the hydraulic fluid, is allowed to expand because of a low-pressure situation. This occurs in pump inlets, which by nature have a low-pressure condition. The expanded gas bubbles at the inlet collapse with considerable force as the pumping chamber is exposed to system pressure. This collapsing action results in rapid energy losses in the form of heat and noise. This energy level is also high enough to cause serious damage to the lens plate and/or the cylinder barrel of the pump.

Aeration is somewhat different than cavitation, however the resulting noise and damage to the pump is nearly identical. Aeration occurs when there are air bubbles present in the reservoir fluid at atmospheric pressure (typically caused by excessive foaming or vortexing at the pump inlet). These air bubbles are then drawn into the inlet line of the pump and ultimately cause of the same damage as described in cavitation.

5.9 Proportional Valves

Proportional load-sensing type valves are used where variable flow is required. Refer to the Troubleshooting Section and Electrical Section when determining operating problems.

PM Tasks

Periodic maintenance is limited to external inspections. Overhauling the control valves includes replacing O-rings and seals, and setting the pressure and flow. See Section 5.9.1 Proportional Valve Settings for these specifications. If additional parts need servicing, it may be more economical to replace the individual valve sections.



• Operate controls to check for proper operation.

WARNING!


CAUTION!

Operating pressure in hydraulic pump must be set correctly before performing this adjustment.

Improper Makeup & Breakout Speed may damage equipment or drill pipes.

All proportional valves are equipped with white/grey connectors.

6.3 GREASE INJECTION (08/03/25) 6-03-001

6.3 Grease Injection

The grease pump injects grease into the drilling air stream (see Fig 6.3.1). It is a pneumatically-operated unit that develops a fluid pressure of twenty five times higher than its air supply pressure.

PM Tasks

Keep grease tank, pump, injector, and valves clean. The grease tank is the main source where contamination may enter into the grease system. Drain and lubricate air supply.

Replace damaged components immediately. Investigate all leaks. All maintenance should be performed in a clean, well-lit work area. Extreme cleanliness is required when servicing injecting system components.

Fill up grease tank (1) periodically in order to avoid air trapped in the lines. Add grease every time the grease level drops below middle window sight.

Every shift: • Check grease level in the tank (1), drain air filter (3), and check oil in air lubricator (4).

250 Hour Intervals: • Inspect system for leaks

The grease injection system settings are:

- air pressure in the grease pump (2) – by regulator (7).

- cycle time (from 20 sec to 24 hr) – controlled by the ERIS Panel or manual timer.

- amount of grease injected in a cycle – by adjusting the injector (6) to suit the drill hole size (see specifications below).

WARNING!


6.3.1 To Fill Reservoir

Remove fill cap, fill with grease until level reaches top window sight.

NOTE: When filling the reservoir, caution should be used not to contaminate reservoir.

6.3.2 To Prime System

Supply Lines: After grease tank has been filled with recommended lubricant, turn vent plug counterclockwise one complete turn and operate pump until lubricant flows freely from opening in vent plug to expel air pockets trapped. Tighten vent plug.

Feeder Lines: Fill each feed line with lubricant before connecting lines to outlets.

Injectors: Check injector for proper operation. Injector stem moves when injector discharges grease. This may require cycling system several times. After checking adjust injector for the volume required.

6.3.3 Operation

The pre-determined lubrication cycle frequency is set by the operator using a manual timer.

When a lubrication cycle is initiated, the air solenoid valve is energized and air is admitted to the pump. Lubricant is delivered to the injectors and the injectors discharge lubricant to the drill air line. When air sol valve is de-energized, air is admitted to the opposite side of the pump air cylinder. As pump plunger returns to its retracted position, the lubricant pressure in the system is relieved, permitting the injectors to recharge.

System is now ready for the next lubrication cycle.

6.3.5.1 Basic Operation

Selector Settings

The selectors can be turned clockwise and counterclockwise to select the desired time scale or operating mode.

Each selector has a snap mechanism that secures the selector at a given position. Set the selector at a position at which it is secured. Do not set it midway between two secure positions, or a malfunction could result from improper setting.

Settings for ON-Start/OFF-Start

If voltage is applied to terminal B1, or if terminals A1 and B1 are shorted, the operating mode is switched to ON-start mode. If these terminals are disconnected, the mode switches to OFF-start mode. The operating mode will not change if the state of the applied voltage changes during timer operation.

Selection of Time Scale

Refer to Fig 6.3.4

The time scale is selected by turning the ON-time scale selector and OFF-time scale selector. The time scales will appear in the following order in each time scale display window on the left of the selector:

0.1 s, 1 h, 0.1 h, 1 m, 1 s, 0.1 h, 0.1m, 1 s.

Time Setting

Use the ON-/OFF-time setting dials to set the ON-/OFF time.

Locking/Unlocking Selectors and the Time Setting Dial

Refer to Fig 6.3.5

The ON-/OFF-time setting dials and time scale selectors can be locked using the Y92S-38 Lock Key, a special pen-type tool that is sold separately. To lock the dials or selectors, insert the Lock Key in the keyhole to the lower right of the dial or selector and turn it clockwise until the dial or selector is completely covered with the red cover. To unlock, turn the Lock Key in the opposite direction.

Grease 12 seconds on (ON-time set to 2, Time scale set to 0.1 m)

24 seconds off (OFF-time set to 4, Time scale set to 0.1 m)

6.4 FIRE SUPPRESSION SYSTEM (08/03/25) 6-04-001

6.4 Fire Suppression System

The fire system described is a suppression system only and is not designed or intended to extinguish all fires. It is extremely important that alternative firefighting equipment be available in case the system does not totally extinguish a fire.

When a fire is detected, the A-101 system is actuated either manually or automatically, operating the pneumatic actuator. The pneumatic actuator ruptures a seal disc in the expellant gas cartridge. This, in turn, pressurizes and fluidizes the dry chemical extinguishing agent in the tank, ruptures the burst disc when the required pressure is reached, and propels the dry chemical through the network of distribution hose. The dry chemical is discharged through fixed nozzles and into the protected areas, suppressing the fire.

In Case of Fire

1. Shut down the drill and set the brakes

immediately.

2. Pull the ring pin on the manual actuator and strike the red plunger button (see Fig 6.4.1).

3. Evacuate the vehicle.

4. Stand by with a hand portable fire extinguisher.

Fig 6.4.1 Pull pin. Strike plunger.

NOTE: Do not restart drill until drill has been repaired and fire suppression system has been recharged.

What to Expect

When an A-101 system discharges, there is considerable noise accompanied by clouds of dry chemical. While breathing foreign particles is not pleasant, the agent FORAY is non-toxic and exposure during a fire will not harm you.

After the Fire is Out

Machinery should not be restarted until it has been serviced and cleaned (water may be used to remove the dry chemical). IMMEDIATELY recharge the fire suppression system. You needed it once; you may need it again.

CAUTION!

Heat remaining from the fire could cause re-ignition after the system has discharged. Because of this, it is important that someone stand by, at a safe distance, with a hand portable extinguisher. This standby should be maintained until all possibility of re-ignition is past.

6.4.1 System Description

Refer to Fig 6.4.2. The basic system consists of the following components:

Dry Chemical Agent Storage Tank(s)

The agent storage tanks consist of a welded steel tank, gas tube, brass or aluminum fill cap, agent outlet sealed bursting disc assembly, and instruction nameplate.

Expellant Gas Cartridge

The expellant gas cartridge is a spun high pressure cartridge containing either carbon dioxide for temperature ranges of +32°F to +120°F (0°C to +49°C), or nitrogen for extreme temperature ranges of -65°F to +210°F (-54°C to +99°C).

Manual/Automatic Actuator

The manual actuator consists of an actuator body, a nitrogen cartridge, and a mounting bracket. When the manual actuator is operated by hand, gas supplied from the nitrogen cartridge is released into ¼” actuation hose. The nitrogen pressure then operates the pneumatic actuator that punctures a larger expellant gas cartridge (either carbon dioxide or nitrogen) and this fluidizes and propels the dry chemical from the agent storage tank.

Automatic actuators (a component of the automatic detection system) operate the same way, except they can be operated automatically by the detection system.

Automatic Detection System

The automatic detection system in use on your drill is the Checkfire SC-N.

The Checkfire SC-N Electric Detection and Actuation System consists of the following components:

• Control Module

• Manual/Automatic Actuator

• Mounting Bracket

• Detection Wire

• Thermal Detectors

• Pneumatic/Linear Detection

• Squib

• LT-5-R Cartridge

• Check Valve

• Remote High Level Alarm

• Squib Circuit Test Module

Front Panel Indicators

Battery Trouble (Yellow)

LED pulses once every 10 seconds when indicating battery trouble.

The yellow battery trouble LED will pulse when a low power condition is detected. If a power source is once connected and recognized, a subsequent loss of that power source will be recognized as a Battery Trouble condition. If a power source is once connected, recognized, and then disconnected, the disconnected supply can be ignored by operating the RESET button.

Power Normal (Green)

LED pulses once every 3 seconds when indicating normal power.

The green Power Normal LED pulses ‘on’ once every 3 seconds indicating power is normal. If the power drops below an acceptable level, the green Power LED will be extinguished

Alarm (Red)

The alarm LED will flash if an alarm condition exists. An alarm condition is caused by operation of the detection circuit or operation of the manual pull/pressure switch input circuit. The alarm condition will continue until the source of the alarm is removed and the control module is reset.

Detection Circuit Activation Mode

Upon receipt of an input to the detection circuit, the Alarm LED and the sounder will pulse at a rate of 2 times per second and will continue at this rate until the first time delay period has expired.

After the first time delay, a second time delay mode is initiated. This causes the LED and sounder to pulse at a rate of 4 times per second.

After discharge, the LED and sounder will continue to pulse at a rate of 4 times per second for 30 seconds. After that, it will switch to the trouble mode and pulse once every 10 seconds.

Electric Manual Release Mode

The first time delay mode will be by-passed and the LED will pulse at a rate of 4 pulses per second. After the first time delay setting is reached, it will pulse another 30 seconds at the same rate. After that, the control module will go into the post-discharge mode, at which time the Alarm LED and Release LED will pulse at a rate of one pulse per 10 seconds.


Pressure Switch Circuit (Feedback) Activated Mode

When this mode is actuated, the Alarm LED will pulse a minimum of 30 seconds at 4 pulses per second. The control module will then go into the post-discharge mode and the Alarm and Release LED will pulse at a rate of one pulse per 10 seconds.

Release Trouble (Yellow)

The yellow Release LED and the audio will pulse at a rate of once every 10 seconds when a trouble condition is detected in the release circuit. The control module will return to normal when the trouble condition is cleared.

The Release trouble will also pulse after the system has completed a discharge cycle or a pressure switch feedback signal has been received. The trouble signal in this condition is used to indicate a recharge of the fire suppression system is necessary. A Release trouble under either of these conditions can only be cleared by resetting the control module.

Detection Trouble (Yellow)

The yellow Detection trouble LED and the audio pulse once every 10 seconds when the control module detects a trouble in the detection circuit. The control module will automatically return to normal when the trouble is cleared.

Sounder (Audio)

The sounder gives the audio indication for all alarm and trouble outputs. The sounder will pulse at the same rate as the visual corresponding LED>

The sounder gives the audio indications of the various outputs. The sounder is rated at 85 Db at 10 feet.

The pulse rates are as follows:

Alarm – Time Delay 1 – 2 pulses per second

Alarm – Time Delay 2 – 4 pulses per second

Trouble – 1 pulse per 10 seconds

Loss of Power – 1 pulse per 10 seconds

Release Circuit Fired – 4 pulses per second for 30 seconds, then 1 pulse per 10 seconds

Low Battery – 1 pulse per 10 seconds


Front Panel Buttons

Delay

Pushing the Delay button during the first time delay cycle will restart the time delay cycle. If the second time delay cycle has already started, the Delay button will have no effect.

The Delay button can also be used to check the diagnostics function. By depressing the Delay button when the system is in the trouble condition, the LED’s will flash a pattern code. Each pattern code indicates a certain type of trouble. The code pattern is prioritized. The first trouble must be addressed before addressing the next one. Once the first trouble is taken care of, depressing the Delay button will cause the LED’s to indicate the code for the next trouble, if there is one. When the Delay button is pressed, three short audio and visual indicators will acknowledge the switch has been depressed properly.

In a post-discharge condition, pressing the Delay button will silence the alarm relay if the alarm relay has been programmed to silence.

Reset

The Reset button is used to re-initialize the control panel. When depressed, it provides an indication that all LED’s and the sounder are functional.

It is used to upload the manual programming into the control module.

If trouble(s) have not been cleared, the trouble indication will reappear after the Reset button is pressed.

When the Reset button is pressed, three short audio and visual indications will acknowledge the switch has been depressed properly.

Battery Replacement

While in use, the battery requires replacement every year or when the yellow Battery LED and sounder are pulsing.

The shelf life of the battery is 8 years.

Control Module contains a label for recording battery replacement date.

Make certain used battery is disposed of properly.

6.4.3 How the System Operates

Refer to Fig 6.4.5

1. A fire starts in the protected area.

2.1. Manual Actuation – The equipment operator pulls the ring pin and strikes the plunger on the manual actuator. Depressing the actuator plunger punctures the seal on the cartridge. The released pressure is transmitted to the pneumatic actuator/cartridge receiver The pressure through the line triggers a pressure switch set to shut down the drill. A safety relief valve at the pneumatic actuator/cartridge receiver prevents too high an actuation pressure build-up. The pressure drives a puncture pin through the seal in the expellant gas cartridge. This releases the expellant gas which is then transmitted to the dry chemical tank where it fluidizes the dry chemical before carrying it to the fire hazard. A bursting disc in the union assembly prevents the flow of dry chemical until sufficient pressure is built up within the dry chemical tank. When the proper pressure is reached, the disc breaks, allowing the gas/dry chemical mixture to flow to the nozzle(s) and discharge onto the hazard.

2.2. Automatic Detection and Actuation - Linear or spot detectors signal the system control module indicating that a fire has started in the protected area. The control module actuates the fire suppression system.

Upon receiving an input signal from either a shorted detection, the control module will react as follows:

a. The Alarm LED will flash, the sounder will pulse 2 times per second, and the shutdown time delay begins. This delay is intended to give the operator time to shut down and exit the vehicle. (The operator can repeat the shutdown time delay if the Delay button is depressed before the shutdown time delay has expired.)

b. After the shutdown time delay has expired, the Alarm LED pulse rate and the sounder pulse rate will change to four times per second. The equipment will shut down and the discharge time delay begins.

c. After the discharge time delay has expired, the control module release circuit operates, resulting in system discharge (same as when manually actuated).

After system discharge, the Alarm LED and sounder will continue to pulse at 4 times per second for 30 seconds. After that, it will switch to the trouble mode and pulse once every 10 seconds. It will continue to pulse until the system has been recharged.


6.4.4 Recharge Procedures

Recharging the Checkfire Detection and Actuation System

For continued protection, the Checkfire SC-N Detection and Actuation System and the fire suppression system must be recharged immediately after operation.

Before performing the recharge steps, determine the cause of the system discharge.

1. Remove the 4 screws holding the cover to the back box and remove the cover.

2. Remove the battery from the back box.

NOTE: If the system contains optional vehicle power, also disconnect the wire leads at the vehicle battery.

3. Remove the empty LT-5-R cartridge from the manual/electric actuator.

6.5.1 Sullair Compressor Unit

Refer to Fig 6.5.1, Fig 6.5.2, Fig 6.5.3, Fig 6.5.4, and Fig 6.5.5

Functional Description

The compressor unit supplied with this booster is a one stage positive displacement, high pressure, flood lubricated type rotary screw air compressor, utilizing mine-supplied compressed air to act as a primary stage.

The compressor unit utilizes two rotors to compress the incoming mine air. A driven male rotor drives a female rotor and, as they turn, compressed air is drawn into the unit through the inlet system where it is trapped in the grooves of the rotors and forced around to the discharge side of the case, recompressing it to obtain a higher pressure. The quantity of air can easily be controlled by regulating the amount of incoming air or by varying the speed at which the unit rotates. By changing gear sets we are able to use the same air end to give us different capacity units.

NOTE: Each Sullair rotary screw compressor uses oil as a lubricant sealant and coolant medium (mineral or synthetic). Due to the many types of oil used in the marketplace, this manual will refer to oil as “fluid”.

Fluid is injected into the compressor and mixes directly with the air as the rotors turn, compressing the air. The fluid has three main functions:

1. As a coolant, it controls the rise of air temperature normally associated with the heat of compression.

2. It seals the leakage paths between the rotors as well as between the rotors and stator.

3. It acts as a lubricating film between the rotors allowing the male rotor to directly drive the female rotor, which is an idler.

After the air has been compressed, it is discharged in the form of an air/fluid mixture. This mixture is routed through the discharge system where the fluid is separated from the air. Then the air flows to the service line and the fluid is directed through the cooling and lubricating system in preparation for re-injection.

6.5.2 Compressor Discharge System

Refer to Fig 6.5.6, Fig 6.5.7, Fig 6.5.8, and Fig 6.5.9


The Sullair compressor unit discharges a compressed air/fluid mixture into the sump. The discharge valve is located on the compressor unit at the end opposite the drive shaft. The discharge check valve prevents discharged air from returning from the compression chamber or sump on shutdown.

From the discharge valve, the air/fluid mixture is directed to the sump. The sump has four basic functions:

1. It acts as a primary fluid separator.

2. It serves as the compressor fluid sump.

3. It houses the final fluid separator.

4. It serves as an air tank receiver.

The compressed air/fluid mixture enters the sump and is directed against the end of the tank. By change of direction and reduction of velocity, larger droplets of fluid fall to the bottom of the sump. The fractional percentage of fluid remaining in the compressed air collects on the surface of the final separator element as the compressed air flows through the separator.

As more and more fluid collects in the element surface, the fluid descends to the bottom of the separator. A return line (or scavenger tube) leads from the bottom of the separator element to the gear case of the compressor unit. Fluid collecting on the bottom of the separator unit is returned to the compressor gear case. An orifice (protected by a strainer) is included in this return line to assure proper flow.

The sump is ASME code rated at 600 psi (2758 kPa) working pressure. A minimum pressure valve is located downstream from the separator to assure the required minimum receiver pressure during all conditions. This pressure is necessary for proper fluid circulation and air/fluid separation.

The system is protected from excessively high sump pressures by a high-pressure shutdown switch (set at 440 psi), which will shut the compressor unit down. A second protection for high discharge pressure utilizes a 550 psi pressure relief valve, which is located on the wet side of the separator and is vented to atmosphere. Also, a High Compressor Discharge Temperature Shut Down (set at 240°F) and High Receiver Temperature Shut Down (set at 220°F) will shut the compressor unit down if the temperature exceeds the normal operating range.


Fluid is added to the sump via a capped fluid filler opening placed low on the tank to prevent overfilling to the sump. A sight glass enables the operator to visually monitor the fluid sump level. The proper level is halfway of the sight glass when the unit is shut down.

DO NOT OVERFILL.

WARNING!

DO NOT open the fluid filler cap when the compressor is pressurized. Shut down the compressor and bleed the sump to 0 psi before removing the cap.

A hydraulically operated, 2-inch ball valve is used to open and close the discharge air when required.

6.5.3 Compressor Cooling and Lubrication System

Refer to Fig 6.5.10, Fig 6.5.11, and Fig 6.5.12 (next page)


The booster cooling and lubricating system is designed to provide adequate lubrication as well as maintain the proper operating temperature of the booster. In addition to a cooler and fan, the system consists of a main fluid filter, thermal valve, fluid stop valve, and pressure bypass valve.

Fluid is used in the system as a coolant and a lubricant. The fluid is housed in a receiver/sump. Upon start-up, the temperature of the fluid is cool and routing to the fluid cooler is not necessary. The fluid, taking the path of least resistance, flows through the thermal valve to the compressor unit.

The thermal valve has two entrance ports and two exit port. These ports are stamped on the thermal valve body indicating:

A - From tank

B - To cooler

C - From cooler

D - To compressor

As previously stated, upon start-up the fluid temperature is cool and routing to the cooler is not required. The fluid first enters the thermal valve and then flows on to the compressor unit, bypassing the cooler. As the compressor continues to operate, the temperature of the fluid rises and Port A of the thermal valve begins to close. The closing of Port A forces a portion of the fluid through the fluid cooler.

The cooler is a radiator type cooler that works in conjunction with the fan. The fan forces air through the cooler, removing the heat of compression from the fluid. From the cooler, the fluid is routed back to the thermal valve, entering at Port B. Before the temperature of the fluid becomes high enough that Port A is completely closed, cooled fluid at Port B is mixed with warmer fluid entering Port A.

When the temperature of the fluid reaches 250°F (121°C), Port A is completely closed, causing all fluid to flow to the cooler. The pressure bypass valve insures a supply of fluid to the compressor during periods of excessive pressure drops across the cooler, which may occur in extremely cold weather. After the fluid passes through the thermal valve, it is then directed through the main fluid filter. There the fluid is filtered in preparation for injection into the compression chamber and bearings of the compressor unit.


Fig 6.5.10 Fluid Stop Valve Fig 6.5.11 Main Compressor Fluid Filter

Fig 6.5.12 Cooling and Lubrication


The filter has a replaceable element and a built-in bypass valve, which allows the fluid to flow even when the element becomes plugged and requires changing, or when the viscosity of the fluid is too high for adequate flow.

After the fluid is properly filtered, it lubricates, seals, and cools the compression chamber as well as lubricating the bearings and gears. The fluid stop valve is held open by a pressure signal from the compressor unit. At shutdown, the pressure signal is lost and the fluid stop valve closes, isolating the compressor unit from the cooling system.

A Low Oil Pressure Shut-Off (set at 120 psi) will shut the compressor unit down in the event of low or no oil pressure. Another shutdown, the Oil Stop Signal Pressure Switch (set at 90 psi) will shut the compressor unit down in the event of a lost signal pressure to the oil stop valve.

6.5.4 Air Inlet System



The compressor inlet system consists of one mine air filter, a water separator, gauges to monitor filter condition and mine air, shutdown systems for low mine air and air filter restrictions, 3” ball valve, compressor air inlet valve, and interconnecting piping to the compressor.

The air filters are dry element type filters capable of cleaning extremely dirty air and are equipped with an auto water discharge system plus an auto drain valve. Reading pressure\differential between incoming air and discharge air on the filter housing monitors air filter condition (differential should not exceed 5 psi).

The compressor unit is protected from damage, caused by low mine air supply, with a low mine air shutdown switch. In the event of low mine air (60 psi) the compressor unit will shutdown after a twenty second delay. Also incorporated is a low compressor inlet shut off which will shut the compressor unit down after a twenty second delay. This shutdown will monitor restricted airflow through the air filters (20 psi differential).

Shutdown on low mine air will require diagnosing and repair of mine air supply.

Shutdown on low compressor inlet pressure will require the change of air filter elements. It would be advisable to verify the presence of the correct mine air pressure before assuming that the filters need replacement. This could happen in the event that the low mine air shutdown switch malfunctioned or was incorrectly set.

NOTE: When checking mine air pressure, it is necessary to do so while the compressor is in operation. Static air pressure can significantly drop while making air.


6.5.5 Compressor Lubrication Guide

The reliability of the unit is dependant upon the selection and maintenance of the lubricant. The ambient temperature, relative humidity, discharge pressure, and contamination levels must be considered in the lubrication selection. All lubrication oil(s) mentioned will be referred to as “fluid”.

Fluid Type Change Period (hrs) Range °F (°C) Sullair AWF (I) 1200 -20 to 120 (-29 to 49)

D-A Torque Fluid 300 10 to 110 (-12 to 43)

SAE 10W SE, SF, SG, CD 300 0 to 100 (-18 to 38)

MIL-L-2104E 10W 300 0 to 100 (-18 to 38)

6.5.6 Application Guide

Water must be drained from the receiver periodically. In high ambient temperature and high humidity conditions, condensed moisture may emulsify with the oil forming a “milky” colour. ATF is especially prone to this condition. The fluid should be changed if this condition develops.

WARNING!

DO NOT mix different types of fluids. Combinations of different fluids may lead to operational problems such as foaming, filter plugging, and orifice or line plugging.

When ambient conditions exceed those noted or if conditions warrant the use of other extended life lubricants, contact Cubex for recommendations.

Cubex encourages the user to participate in a fluid analysis program. This could result in a fluid change interval differing from that stated in the manual.

Fig 6.5.16 Air Inlet Valve Fig 6.5.17 Cross Section of Fig 6.5.16

Fig 6.5.18 Control Circuit


6.5.8 Capacity Control System



The purpose of the control system is to regulate the amount of air intake in accordance with the amount of air being used. The one stage hi – pressure screw is designed to operate in one of two modes of operation, the low-pressure mode (approx. 200 psi) and the high-pressure mode (up to 410 psi). The Control System consists of an inlet control valve, running blow-down valve, shut down blow-down valve, shut down blow-down solenoid valve, low air pressure solenoid, manual selector, signal line bleed solenoid, orifice, signal line silencer and a blow-down silencer.

Refer to Section 6.5.7 for a description of valves and functions.

The position of the pressure selectors determines the pressure that the control system will respond to. The functional description of the control system is described in seven distinct phases of operation which (except for the start phase) apply to both high and low pressure modes.

The inlet control valve is a normally closed valve. Signal pressure regulates the incoming air to control output flow of the compressor unit.

6.5.9 Compressor Start Up Mode

Refer to Fig 6.5.19

The inlet system incorporates an N/C inlet valve, which opens when mine air pressure is applied to it. The opening and closing of the valve is controlled by a pilot signal from various valves in the system. To prevent the inlet from remaining open when the mine air is turned on and the compressor unit not running (causing the compressor to turn without lubrication) an N/C solenoid valve is installed between the mine airline and inlet valve signal line. This solenoid is protected from high air pressure by a one- way check valve. When the compressor unit is not running the valve is open allowing mine air to be applied to the piston side of the inlet valve, closing it. Upon start up the solenoid closes and turns off the signal to the valve, allowing the valve to open.

NOTE: On shutdown, it is advisable to close the 3” inlet ball valve to prevent accidental compressor rollover.

On start up, a series of events happens simultaneously to insure the correct start up of the compressor unit (with the manual unload valve in the load position).

1. The anti-rollover solenoid energizes, closing the N/O solenoid valve blocking mine air supply to the piston side of the inlet valve. This allows the inlet to open and the compressor begins to compress air.

2. The signal line bleed solenoid energizes, closing it to prevent the signal line from bleeding to atmosphere. An orifice is installed to relieve pressure when it is not required, also increasing sensitivity as well as bleed moisture from the system.

3. The shutdown blowdown solenoid valve opens, allowing signal pressure to both the oil stop valve and shutdown blowdown valve. The signal pressure opens the oil stop valve to allow oil to flow to the compressor unit (oil flow is accomplished because the air pressure in the receiver forces the oil into the oil system); also it closes the shutdown blowdown valve to stop air from exhausting from the receiver tank.

4. Receiver tank pressure builds and the minimum pressure valve located on the discharge of the receiver tank maintains a minimum pressure. This insures adequate oil flow.

5. The high - low solenoid valve opens (maintains open position for 2 mins.), applying a signal to the running blow down valve. The running blowdown valve opens and exhausts receiver pressure to the atmosphere; also a signal is sent to the inlet valve to partially close it. A modulating effect occurs at this time until the system balances, where the amount of air being exhausted is the same as the inlet is allowing into the compressor unit. This is the maintained low pressure (approx. 200 psi).

6. The 2” discharge valve is closed.


6.5.10 Running Mode Low Air Pressure

Refer to Fig 6.5.20

After 2 minutes, the system is now fully functional. The running mode is the same as the start up mode except that the high - low selector now becomes operational. The drill air on/off switch controls this. Hole collaring is achieved by using the collar air function on the driller station. When operated, the 2” ball valve opens and the high - low solenoid remains energized, maintaining low pressure while collaring the hole.

NOTE: Before switching the unit to high air pressure, the collar air function must be turned to the off position.

Fig 6.5.20 Compressor Start Up Mode / Running Mode Low Air Pressure









6.5.11 Manual Unload Low Mode

Refer to Fig 6.5.21

The system can be manually unloaded to run in the low air pressure mode. When the manual unload valve is turned, a signal is sent to open the running blowdown valve and close the inlet control valve.

Fig 6.5.21 Manual Unload Low Mode

Manual unload valve opened


Intake control valve modulating

Low air pressure solenoid valve closes


6.5.12 Drilling Mode High Air Pressure

Refer to Fig 6.5.22

When drill air is selected, the high - low selector now de-energizes and closes, and the 2” ball valve opens, allowing air to the hammer. At this time, the pilot signal to the running blowdown valve and inlet valve is lost. The receiver tank is no longer vented to atmosphere and the inlet valve opens, allowing the compressor to work to maximum. Because the compressor is capable of producing more air than is required, the pressure builds in the system.

Fig 6.5.22 Drilling Mode High Air Pressure








6.5.13 Drilling Mode High Air Pressure Unloaded Position

Refer to Fig 6.5.23

Once the pressure reaches 400 psi, the Inlet Signal Pressure Regulator opens, sending a pilot signal to the inlet to close it. The valve will modulate open and closed to maintain system pressure. If the pressure continues to build, the High Air Pressure Regulator set to 410 psi opens, sending a signal to both the inlet valve and running blowdown valve. This opens the running blowdown valve to allow excessive air to vent to atmosphere to aid in control of the system.

Fig 6.5.23 Drilling Mode High Air Pressure Unloaded Position

High air pressure regulator reaches 410 psi

Regulator opens when system pressure reaches 400 psi


6.5.14 Shutdown Mode

Refer to Fig 6.5.24

On shutdown, the high - low solenoid is energized, opening the running blowdown valve and supplying a signal to close the inlet valve. The system is held in low mode for 2 minutes to allow the system to stabilize and the separator to clear itself of excessive oil.

Fig 6.5.24 Shutdown Mode









6.5.15 Shutdown Mode after 2 Minutes

Refer to Fig 6.5.25

After 2 minutes has elapsed, the compressor unit shuts down; at this time all the solenoids de-energize. The shutdown blowdown solenoid closes, removing the pilot signal from the shutdown blowdown valve allowing it to open and drain the receiver tank to atmosphere. The signal line bleed solenoid opens, draining any residual signal line pressure to atmosphere. The low air pressure solenoid closes, allowing the running blowdown to close and removing the signal from the inlet valve. Also the anti-rollover solenoid opens to allow mine air to close the inlet valve to prevent compressor rotation.

There is a comprehensive instrumentation and protection group on this unit to protect both the operator and unit. This package includes visual aids, shutdown protection devices, visual alarms, and audio alarms.

The instrumentation group is controlled by a PLC with a display to allow for visual verification of the operating pressures and temperatures of various systems incorporated into the compressor unit. These would include the following:

• Receiver and Discharge temperatures

• The Oil, Receiver, Separator Differential and Inlet/ Mine Differential Pressures

• The Blowdown Valve Status - This should show ON during the first minute of start-up and shutdown.

• The PLC Battery Status - This should show OK at all times. If it shows FLT, the PLC battery must be replaced.

The PLC battery part # LS14250 should be replaced regularly to avoid loss of data. Please see the following page for instructions on replacing the battery.

There are shutdowns incorporated in order to protect the unit and personnel from damage and / or injury. These shutdowns will shut the compressor unit down in the event that any of the systems operate out of their designed parameters. Also, whenever a shutdown is activated, a visual beacon (an indicator light to identify the system) and an audio alarm will be set off to notify the operator that there is a system problem.

• Low inlet pressure shutdown set at 60 psi.

• Low oil pressure set at 120 psi.

• High receiver pressure set at 440 psi - immediate shutdown.

• High discharge temperature set at 240°F - immediate shutdown.

• High receiver temperature set at 220° F - immediate shutdown.

• Motor overload (located in the electrical panel)

• Phase reversal (located in the electrical panel)

• Mine air filter pressure differential switch set to 20 psi

• Separator filter pressure differential switch set to 10 psi

• Oil stop signal pressure switch set to 90 psi


When an alarm occurs, the horn will sound and a warning light on the indicator panel will light. The operator can push the Silence button to silence the horn. This action will also turn off the warning light if the alarm conditions have been cleared.

If the warning light remains on after the silence button has been pushed, an error condition is still present.

Investigate the error condition and correct any problems. Press the Lamp Test/Reset button. If the error condition has been cleared, the warning light will go off.

6.5.18 Adjustment Procedure


This unit only requires the adjustment of 2 valves on setup. They are the High air pressure regulator (set at 410 psi) and the Inlet signal pressure regulator (set at 410 psi). The adjustment of these regulators is best done while drilling but can be preset in the shop. In order to check the operating pressures of the compressor unit while in the shop, it will be necessary disable the service valve, keeping it closed so that the compressor will build pressure (when the drill air switch is turned on, the unit switches to high mode and opens the service valve, allowing all the air out of the top drive).

Start the unit and wait 2 minutes for the system to enter the running mode. Turn the manual unloader to low position and then move the drill air switch to the on position. Switch the manual unloader to high position and check the system pressure (should be 400 psi). In order to verify the opening pressure of the High air pressure regulator, the Inlet signal pressure regulator will have to be adjusted upwards by turning the screw in clockwise. Turn the screw in until the pressure quits rising. This is the set pressure of the High pressure regulator. If it is not correct, adjust it in the same manner as the inlet signal pressure regulator. Once completed, readjust the Inlet signal pressure regulator until the system maintains 410 psi.

Set pressures to:

Inlet signal pressure 410 psi

High air pressure 410 psi

Fig 7.1.1 ERIS Control Panel


7.1.1 ERIS Control Panel

The ERIS Machine Operator Interface is a PC based system comprising of a unique custom designed enclosure, hardened mobile computer, joysticks, USB (Universal Serial Bus) interface, power supplies for the computer and necessary software.

The computer is connected to the joysticks through a USB interface. There is also a data port located on the upper left hand side of the enclosure that is connected to the computer through a USB connection. The port can be used for downloading software or for up-loading data as required. The data port is protected by a threaded plug and to access the port, this plug must be removed.

The procedure for communicating with the computer through the external port is described later.

The computer communicates to the main machine PLC over Ethernet. The connection is made at internal computer and passed through a plug at the back of the panel.


Fig 7.1.2 Wiring Diagram

Fig 7.1.3 Parts (see Parts Manual for details)


7.1.2 Communication with the ERIS Console

There will be instances where a technician will need to connect to the ERIS console. A few of these instances may be:

• To install a newer or different version of the ERIS software.

• To configure the Joysticks.

• To verify the console is communicating with the PLC.

• Verify computer settings.

To allow a technician to communicate with the ERIS console, there is a threaded plug in the top left corner of the panel. When this plug is removed, it reveals a USB connection.

In order to communicate with the internal CPU in the ERIS panel without disassembling the console, what is needed is a USB keyboard. The keyboard can be plugged into the external USB port and the keyboard then can take over control of the computer.

NOTE: It is recommended that a special keyboard and flashdrive should be used for this purpose that has been tested for compatibility to ensure reliable connectivity through the USB port.

This is available through your local dealer under the following Cubex part numbers:

• CP000272 USB keyboard with pointing device and two USB ports.

• CP000271 512MB USB flashdrive.

7.1.2.1 Communication with the ERIS Console from the External USB Connection

The ERIS console must be powered up.

1. Plug the USB keyboard into the external USB port on the console.

2. If the console is in the control mode with the GUI (Graphical User Interface) showing on the monitor, hit Escape on the keyboard. This should bring the display to a Windows® environment.

At this point, the joysticks can be calibrated and/or new code (software) can be loaded.


7.1.3 Checking the Joysticks

In general, the joysticks should not need calibrating, even when they come from the factory. However, optimum gain characteristics (the distance the joystick moves vs. the amount of output signal) may only be achievable through the process of making certain the joysticks are properly calibrated.

The process of checking the joysticks is as follows:

1. Click on the Start button in Windows®, then to Control Panel, then Game Controllers. The following screen will display:

Fig 7.1.4

This screen identifies that the A/D (analog to digital) Controller is communicating with the computer.


2. Next click on Properties. The following screen will appear.

Fig 7.1.5

3. The buttons on the joysticks can then be checked for communication with the computer. Press each button in turn, one at a time.

When pressing a button on the joystick, the corresponding button on the screen (see Fig 7.1.5) will light up. The light number 13 will show as being constantly on. This light represents the tilt switch that is built into the PCB (printed circuit board). If the ERIS panel is tilted, this light should go out.

Fig 7.1.6 reflects the button numbering sequence the computer recognizes from the USB controller.

Fig 7.1.6


4. The visual graphics for testing the “X” (right to left) and “Y” (back and forth) axis of the joysticks is slightly different between right and left joystick. As shown in Screen 2, the left joystick is represented by cross hairs in a square. When the left joystick is moved in its extreme pattern (move the joystick in a complete circle, pushing it as far to the outside edge as possible), the cross hairs should touch the sides of the box. If it does not, the left joystick should be calibrated.

The right joystick is then confirmed through the slide bar graph as shown in Screen 2. While moving the right joystick in its extreme pattern, the slide bars should touch the top and bottom of the graph. If it does not, then the joystick should be re-calibrated.

7.1.3.1 Calibrating the joysticks:

1. Select Settings on the Properties window.

The following screen will appear:

Fig 7.1.7

2. Click the Calibrate button (see Fig 7.1.7).


A Calibration Wizard window will appear (see Fig 7.1.8) and lead you through a series of steps to calibrate the joysticks. All instructions can be found at the top of the screen (see Fig 7.1.9 through Fig 7.1.13).

Fig 7.1.8

3. Grasping the left joystick, move it around in a circle as far as it will go. Then press any button on the joystick. Refer to Fig 7.1.9

Fig 7.1.9


3. Next, verify the center point of the left joystick by leaving it centered and clicking next. See Fig 7.1.10

Fig 7.1.10

4. Moving onto the right joystick, the screens will change. Even though the screen will indicate “Y Rotation”, this is actually calibrating the “X Axis” of the right joystick. See Fig 7.1.11

Fig 7.1.11


5. Even though the screen will indicate “Z Rotation”, this is actually calibrating the “Y Axis” of the right joystick. See Fig 7.1.12

Fig 7.1.12

6. The calibration of both right and left joysticks should now be complete. See Fig 7.1.13

Fig 7.1.13


7.1.4 Loading New Software

There may be instances where new software needs to be loaded onto the console computer. To operate the ERIS control system, there are two main programs that run. They are:

1. LLMC – Low Level Machine Control

This software runs in the background and is the communication link between the ERIS control console and the PLC. Even with the computer showing a Windows® screen, the LLMC is still running in the background.

2. OCC – Operating Control Console

This software operates the GUI (Graphical User Interface).

In order to load software without having to open the panel, it is necessary to have a keyboard and USB memory stick with the features as noted previously.

NOTE: The possibility of the code (software programs) becoming corrupt and not operating is highly unlikely.

In many instances during troubleshooting, it is historically tempting to ‘blame’ the software program. However, history also reveals that a corrupted code in a computer or PLC is not very common.

There are, however, times when the operating parameters of the Cubex machine change. For instance, the machine may have a carousel installed in the field and need the GUI to change accordingly, or a software revision may come available.

In these instances, the technician will need to download code from the USB memory stick to the ERIS console.

In the event of these software revisions, new code can be emailed to you as an attachment in an email. From the email, the code files can be copied to the special USB memory stick. Once the new code is written to your special low power memory stick and you are armed with your special USB keyboard, the following procedures (rest of Section 7.1.4) are followed for transferring that new code to the computer.


7.1.4.1 Uninstall the Existing Program(s)

1. Power up the ERIS console.

2. If the monitor shows the GUI, hit Escape and bring up the Windows® screen.

Click on the Start button in Windows®, then to the Eris Program Group as shown in Fig 7.1.14.

Fig 7.1.14

3. There are two program groups inside the ERIS program group. Both have to be uninstalled.

We will start by first uninstalling the LLMC program group. Move the mouse over the LLMC folder to expose its contents as shown in Fig 7.1.15.

3. The new ERIS program is now fully installed. Reboot the ERIS panel and the ERIS interface will load automatically.


7.1.5 Ethernet Cable and Plug Configuration

There are different standards that Ethernet cables and cable ends are wired to. In general, when you purchase an Ethernet cable in the local computer shop and use it in an application where the plug remains on both ends, you never have to question the wiring orientation. As long as the same colour wire is connected to the same pin out on both ends of the cable, it does not matter what the colour orientation happens to be.

However, the ERIS console has an Ethernet cable that has the standard RJ45 plug on one end, but the other end is wired to an industrial style of pin connector. Therefore, the colour of the wire and the pin out numbers become an important factor to the technician.

The RJ45 Ethernet cable end that plugs into the computer follows the T-568B standard as shown in Fig 7.1.33. Please take note of the tab orientation on the plug.

Fig 7.1.33

Please refer to the electrical schematic for the corresponding wire orientation in the industrial plug in the rear of the ERIS console.


7.1.6 Panel Layout and Component Replacement

All of these parts are available in a kit CP001096.

Fig 7.1.34


7.1.6.1 Replacement of Power Supply

There is only one power supply in the panel. It converts 24 volts into 16 volts to power the laptop. To remove this, you must first disconnect the two connectors shown in Fig 7.1.35. The power supply is held in place with a silicone adhesive and is pried up for removal.

Fig 7.1.35

To test the output of the power supply, simply disconnect the 16 volt connector (black) and measure the voltage with a meter while the 24 volt is still connected. This will require the plug at the back of the panel to be hooked up to a 24 volt source.


7.1.6.2 Replacement of USB Module

To remove the module, simply disconnect both plugs shown in Fig 7.1.36. This module is also held in place with a silicone adhesive and is pried up for removal.

Fig 7.1.36


7.1.6.3 Removal of CPU (Laptop)

1. Remove the front bezel cover that is retained by 10 socket head capscrews.

2. Remove the trough cover that is retained by 3 countersunk screws.

3. The actuator locking set screw can be loosened and the connector disengaged from the start switch as shown in Fig 7.1.37.

4. Once all the electrical connections have been removed from the CPU, the 4 CPU retaining screws can be removed.

Fig 7.1.37

5. Remove the power, Ethernet, and USB cables from the CPU shown in Fig 7.1.38.

Fig 7.1.38

The computer can now be removed from the enclosure.


7.1.6.4 Heat Sink Connector

Although there is a heat conductive plate built into the back of the ERIS console enclosure, the CPU must make contact with this plate for efficient heat transfer.

This connection is made mechanically with aluminum foil due to the irregular shape of the back of the laptop. It is also important that the mechanical connection can wrap slightly around the edge of the CPU as shown in Fig 7.1.39.

The CPU should come with the heat connection foil in place. However, if it is missing, it can be made up simply by folding several layers of aluminum foil to fit between the “feet” on the back of the CPU. Also ensure it is slightly wrapped around the edge as shown in Fig 7.1.39. The aluminum foil can be held in place by placing 2 or 3 small drops of silicon on the back of the computer.

7.3 TESTING OF VALVE SOLENOIDS (08/03/25) 7-03-001

7.3 Testing of Valve Solenoids

When troubleshooting control valves equipped with remote joysticks, the electrical circuit needs to be tested. There are no simple procedures to determine if the solenoids are defective. Use the elimination process to check related components before replacing the valve solenoids.

Refer to the Troubleshooting Section before performing the following tests.

NOTE: The On/Off valves have different testing method than the proportional valves.

CAUTION!

Eliminate all possible problems before replacing valve solenoids.


Fig 7.3.1 On/Off Valve

Fig 7.3.2 Hirschmann Connector

Fig 7.3.3 Proportional Valve


7.3.1 Types of valves

The circuit voltage in the setup and drilling panel is approximately 24 volts DC. The On/Off valves are equipped with black Hirschmann connectors and have a smaller solenoid than the proportional valves (see Fig 7.3.1).

On/Off valves are used on the following applications:

• Water pump control

• Breakout control

• Slip control

• Centralizer control

• Upper and lower stingers

• Slideover control

• Jacks

• Arm Unit

• Clamp

• Carousel Rotation

• Feed extension control

• Air control

• Dual stingers (if equipped)

Proportional valves with white/grey connectors are installed on the following applications:

• Tram control

• Rotation control

• Feed control

• Mast Swing

• Mast Dump

7.3.2 Testing On/Off Valves

When malfunctioning of the solenoid is suspected perform the following test:

1. Remove Hirschmann connector and check voltage between pin 1 and pin GR (Fig 7.3.2). Zero voltage reading indicates faulty circuit or joystick. Refer to electrical circuits to troubleshoot the problem.

2. If voltage reading is approximately 24 volts, inspect and clean pins in connector and solenoid. Reinstall connector and operate valve. Replace solenoid if valve is not operating.

NOTE: Pin 3 is not used on the ON/Off valves.


Fig 7.3.4 Joystick in Up position

Fig 7.3.5 Joystick in Neutral position

Fig 7.3.6 Joystick in Down position


7.3.3 Proportional Valves

The joystick sends an electrical signal to the electronic module in the solenoid that responds to joystick’s position. This signal (set-point) is converted into a hydraulic pressure which moves the main spool. Inside the transducer (C), the position of the main spool is converted to an electrical signal (feed-back). This signal is registered by the electronics. The variation between the set-point and feed-back signals activates the four miniature valves in the solenoid (see Fig 7.3.3). These miniature valves move the main spool to adjust to the changes set by the joystick.

7.3.4 Fault Monitoring System

The proportional valves are equipped with a fault monitoring system, located in the solenoid, to stop the hydraulic flow in the event of uncontrollable spool movements or positions. It produces a fast and operator-independent reaction to stop the current to the solenoid, causing the main spool to return to the neutral position. The indicator light on the solenoid near the connector changes from green to red when the fault monitoring system is activated.

The fault monitoring system is activated by the following problems:

1. If the set-point voltage is less than 10% or more than 90% of the supply. A short circuit in the wiring harness to the joystick would create a lower set-point voltage.

2. If the feed-back signal from the position transducer corresponds to a main spool travel beyond the set-point signal of 15%. A stuck main spool would not move to neutral position when the operator slows the operation.

NOTE: The monitoring system reacts only to faults of more than 500 ms durations. It continues to interrupt until the problem is repaired, even after restarting the drill.

7.3.5 Testing Proportional Valves

Remove the Hirschmann connector and check the voltage between the pins to pin GR (see Fig 7.3.2).

NOTE: The joystick must be in full up, down or dead center position when checking voltage at pin 1 and 2.

Supply voltage is 24 volts. Actual voltage may vary slightly.

Joystick in up position (see Fig 7.3.4): pin 1: 24 volts DC (100% of supply voltage).

pin 2: 6 volts DC (25% of supply voltage).

Joystick in neutral (see Fig 7.3.5): pin 1: 0 volts DC

pin 2: 0 volts DC


Joystick in down position (see Fig 7.3.6): pin 1: 24 volts DC (100% of supply voltage).

pin 2: 18 volts DC (75% of supply voltage).

Conclusion: If readings match above test, replace the solenoid.

If readings do not match, check the following:

• Joystick not travelling to full position

• Faulty joystick

• Faulty wiring

• Improper voltage

7.4 ALIGNMENT LASER (08/03/25) 7-04-001

7.4 Alignment Laser

7.4.1 Operation

The alignment laser is mounted on the slideover assembly, on both left and right sides (see Fig 7.4.1). To turn on the laser, access the set-up screen of the ERIS panel. Refer to Section 5.6 of the Operator’s Manual. The laser is a simple on/off system.


Should the laser not turn on, use the following procedure:

1. Ensure the output from the PLC is functioning (that the light is on). If the light is not on, your problem is the output from the PLC.

2. If the light is on and the laser is still not working, check the wiring.

3. If the wiring is good and the laser is still not working, you need to replace the laser unit.

7.5 ACCRA-FEED PLC SYSTEM (08/03/25) 7-05-001

7.5 Accra-Feed PLC System (Optional)

7.5.1 Introduction

Cubex Limited, one of Canada’s leading mining equipment manufacturers, introduces another innovation in drilling technology called the Accra-Feed system (AFS). It is controlled by a programmable logic controller (PLC) that provides significant productivity gains through improved hole accuracy and increased drill bit life. The Accra-Feed system can consistently deliver hole accuracy of less than one (1) percent deviation in holes over 30 meters long.

7.5.2 Accra-Feed Operation

During Accra-Feed operation, the forward rotation pressure and holdback relief circuit are combined together; if the drill bit binds in the hole, the rotation pressure will increase in turn, so will the holdback pressure. This will relieve the weight on bit as rotation pressure decreases, and the holdback and feed will return to the pre-set rate. If forward rotation pressure exceeds 1200 psi, the pressure switch will close, sending a signal to the PLC which signals the anti-jam circuit to retract the feed cylinder for two (2) seconds. How far the feed cylinder travels in two (2) seconds is controlled by the anti-jam potentiometer. If forward rotation drops below 1200 psi, feed will resume.

If not, the PLC will again signal the anti-jam circuit. This is a continuous cycle of five (5) attempts. After that, the feed cylinder will retract and stop. Rotation will be maintained and a beacon or alarm will sound (optional).

7.5.3 Accra-Feed Components

Compact Logix PLC

Rotation Pressure Switch

• Monitors forward rotation pressure (set 1200 psi) see hydraulic schematic

Hydraulic On/Off Valve

• This switches between manual operation of the holdback relief circuit and rotation pressure sensing holdback control circuit

When Accra-Feed is on, the Accra-Feed hydraulic valve connects ports 1 and 3

• Holdback is now controlled by rotation pressure

• Manual operation of the holdback relief is not possible

• Pulldown control is still maintained


7.5.4 Maintenance of PLC in Accra-Feed System

Periodically, inspect the tightness of the I/O terminal screws. They become loose over the period of time.

Ensure that components are free of dust.

Check periodically for corrosion of connecting terminals. Printed circuit board and connector may become corroded internally.
