2-2 SECTION 2 – OPERATING INSTRUCTIONS

Timer Switch (2)

The Timer Switch is used to start the timer. Recorder Switch (3)

The Recorder Switch is used to provide power to the recorder and to begin recording. If the Recorder Switch is ON but the recorder does not power-up, verify that the ON/OFF switch on the recorder is turned ON. If the Recorder Switch is turned ON and there is power to the recorder, but the recorder does not collect data, press the REC button on the recorder to begin recording. Coolant Switch (4)

The Coolant Switch is used to manually turn on the cooling water to the cylinder upon completion of a test. The cooling water to the magnetic drive is always ON and is not controlled by the coolant switch. If the automatic shutdown feature is ON, the cooling water to the cylinder will automatically be turned on when an alarm condition is present. Pump Switch (5)

The Pump Switch is used to apply pressure to the cylinder during a test. The Pump Switch is turned ON until the desired pressure is reached and then turned OFF again. Heater Switch (6)

The Heater Switch is used to provide power to the heaters and is used in conjunction with the temperature controller. However, no power is supplied to the heaters until the Heater Switch is placed in the ON position. Motor Switch (7)

The Motor Switch is used to turn the motor on after the slurry cup has been placed in the instrument. The motor rotates at a fixed speed of 150 rpm, so the Motor Switch simply turns it on or off. Master Power Switch and Circuit Breaker (8)

The Master Power Switch on the control panel of the unit controls the power to the control functions of the unit. The Master Power Switch is also a 3 Amp circuit breaker that can be reset by turning the OFF then ON again. Alarm Reset Switch (9)

The Alarm Reset Switch is used to clear the alarm when an alarm condition is no longer present. Recorder Controls (10)

The strip chart recorder is used to record slurry temperature and consistency. The chart speed is fixed at 60 millimeters per hour and is not influenced by power line frequency. Power to the strip chart recorder is controlled by a switch (3) on the instrument front panel.


Refer to the Yokogawa recorder manual for detailed instructions on the operation of this recorder. Model 7050 Temperature Controller (11)

The Model 7050 Temperature Controller controls the 2500-Watt heater inside the test cell. The sample temperature is measured using the centerline thermocouple. The controller may be programmed in a variety of ways to stimulate actual well conditions. For the heater to function the Heater Switch (6) must be turned ON and the temperature controller must be operating. If a heat-up cycle must be stopped, the heater can be turned OFF by turning the Heater Switch to the OFF position or pressing the run/hold button on the controller until the light goes off. The three modes of operation of the temperature controller are as follows: • Ramp and Soak Mode • Multi-Set point Mode • Manual Mode Please see the 7050 Temperature Controller Manual for further detailed instructions on the operation of the temperature controller. Consistency Display (12)

The Consistency Display shows the current consistency value of the slurry being tested. The consistency is displayed in Bearden Units (Bc). The consistency display is equipped with circuitry that is used to sound an alarm and stop the timer when a user specified consistency is achieved. If the automatic shutdown feature is enabled, the alarm will also stop the motor and heater and start the flow of cooling water to the cylinder. As the slurry cup rotates about the paddle as detailed in API Specification 10, the resulting torque induced on the paddle by the slurry is measured using a potentiometer mechanism and a torsion spring. The angular deflection of the spring determines the cement consistency. Pressure Release Valve (13)

The Pressure Release Valve is used to relieve pressure on the test cell. This valve vents the test cell back to the reservoir. It can be slowly cracked open during a test to relieve some pressure in the case of a pressure over-shoot condition, but this should be undertaken with extreme caution. Air Control Valve (14)

The Air Control Valve is a three-way valve used to FILL the test cell and prime the pump, or EXHAUST the air pressure on the cell in preparation for blowing down the test cell. The third position is the AIR OFF position. Air-To-Cylinder Valve

The Air-to-Cylinder Valve sends air pressure to the test cell to force the mineral oil back to the internal reservoir. This operation is known as “blowing down the test cell”.


Auto-Shutdown Features

The Models 7716/7720 include circuitry that can automatically end a thickening time test when a user selectable consistency value is reached. The automatic shutdown feature may be enabled by moving the slide switch below the thermocouple connection, at the rear of the control console, to its left-most position. Enabling the shutdown feature causes the motor and heater to stop and the flow of cylinder cooling water to start when an alarm condition occurs. Additionally, the timer is stopped and the audible alarm is activated.

Preparing the Instrument for a Test Prior to running a test, the following steps must be performed. Configuring the Consistency Display

The instructions for setting the Bearden Unit Alarm Level are listed below. 1. Remove the lid from the instrument. Press down on the flat spring-loaded middle part of

the latch. The latch will fall forward. Press back on the top of latch and lift off lid. 2. Press the ON/OFF switch to the ON position on the main instrument panel. 3. Press the button on the left side of the consistency display’s front panel labeled HIGH

SET PT READ/RST. This will display the consistency alarm high set point. 3. While pressing the HIGH SET PT READ/RST button, adjust the small screw above the

HIGH SET PT READ/RST button labeled ADJ until the desired alarm set point is reached. Clockwise rotation of the screw increases the alarm value while counterclockwise rotation decreases the alarm value. The alarm value may be set anywhere between 0 and 150 Bc.

4. Release the HIGH SET PT READ/RST button when the desired alarm level has been reached. The consistency alarm is now set. Note that the LOW SET PT READ/RST button is not used with this instrument.

5. Once the alarm is triggered it may be reset, by toggling the automatic shutdown switch located on the rear of the control console.

Programming the Temperature Controller

Program the temperature controller to the desired set point. (Following is a brief procedure for programming the controller. For complete instructions, see the Model 7050/7051 Temperature Controller Manual.) 1. Turn the instrument ON and verify that the Thermocouple is plugged in on the backside

of the instrument. If the thermocouple is not attached to the instrument, the temperature controller will display S.Br (Signal Break).

2. Press (page) button until the ProG menu appears. Press (scroll) button until tGt is displayed.

3. Enter the target set point. This value may be less than the current temperature if a chiller is being used. Press (UP/DOWN) buttons to change the value. Wait for the value to flash one time.

4. Press (page) button until ProG menu appears. Press (scroll) button until dur (duration) appears. This is the time to reach the target set point. Press (UP/DOWN)


buttons to change the value. Wait for the value to flash one time. If a ramp rate is used, the controller will prompt for a rate value.

5. Press (page) button until the current process value is displayed. 6. Press the Auto/Man button to place the controller in the Auto mode. 7. Press the Run/Hold button to start the program. The OP1 light should begin flashing

indicating the control output to the heater. API Slurry Cup Preparation

For an accurate thickening time test to be performed, it is important for the slurry cup to be properly maintained and prepared. The following procedure should serve as a guideline for slurry cup preparations. While assembling the slurry cup, refer to drawing 07-0031 in the Drawings section of this manual. 1. Thoroughly clean all parts and verify that all parts are in good condition. 2. Lightly grease all interior surfaces of the slurry cup with white lithium grease or the

equivalent. 3. Install the diaphragm support ring, the diaphragm, and the diaphragm backup plate onto

the paddle assembly. The diaphragm should be oriented so that the larger brass piece is at the top.

4. Slide the shear pin assembly onto the paddle shaft. Place the potentiometer mechanism

on the paddle shaft until it seats. Using an Allen wrench, align the shear pin assembly into the bottom of the potentiometer mechanism and tighten the set screw to secure it in place. Remove the potentiometer mechanism from the paddle shaft.

5. Install the complete paddle assembly into the slurry cup. 6. Screw the diaphragm lock-down ring into the top of the slurry cup while checking to

make sure the paddle turns freely. 7. Invert the slurry cup into the slurry cup support. 8. Prepare a cement slurry in accordance with API Spec 10. Caution: According to API specs: The cement has to be under test (under pressure)

within 5 minutes of mixing. 9. Fill the cup with prepared cement slurry to the bottom of the threads. 10. Remove the plug (pivot) from the center of the bottom cap. 11. Replace the bottom cap without the plug. Slowly screw the cap into place and add

cement through the hole if required. 12. Grease the plug and replace. 13. Rinse the exterior surfaces of the slurry cup.

Running a Test 1. Remove the test cell plug, if it is not already removed from the previous test. 2. Attach the long bail through the holes on the top of the prepared slurry cup and insert it

into the test cell, rotating it until the bottom pins engage the cup drive table. Remove the bail.

3. After the slurry cup is loaded into the cell, the potentiometer mechanism (pot. mech.) is pushed onto the slurry cup paddle shaft and the test cell contact pins. Attach the short bail to the top of the potentiometer and lower the pot mech into the test cell. When properly engaged, the top of the paddle shaft will be flush with the top of the torque measurement potentiometer bearing. Remove the bail.

4. Check to be certain that the slurry cup and pot mech are properly engaged. Turn the Motor Switch to ON. No rubbing noise should be heard.

Shear Pin Assembly


5. Screw the test cell plug into the cylinder by hand. The last turn of the plug seats the O-Ring seal and will offer slight resistance.

Note: Do not over-tighten the test cell plug. Hand-tightening the plug is sufficient

for a complete seal. 6. Slide the thermocouple through the test cell plug into the slurry cup paddle shaft. Start

the threads of the sealing gland into the test cell plug, but do not tighten the thermocouple at this time. Verify that the thermocouple is plugged in at the rear of the instrument.

7. Next, fill the test cell with oil. To accomplish this, close the Pressure Release Valve, and turn the AIR/FILL Control Valve to the FILL position. When oil escapes from the top thermocouple high-pressure fitting, tighten the sealing gland with a 5/8” wrench.

8. Turn the Pump Switch to the ON position to apply the initial pressure to the test cell. When the pressure reaches the desired level, turn the Pump Switch to the OFF position. Adjust the pressure as required throughout the test by turning the Pump Switch ON to increase pressure or by slowly cracking open the Pressure Release Valve to relieve pressure. Use care to open the Pressure Release Valve slowly when attempting to bleed pressure.

9. To begin the test, press the buttons on the temperature controller to AUTO and RUN, turn the Heater Switch to the ON position, and start the timer. Once the desired set point has been reached the alarm will sound. Reset the alarm by pressing the Alarm Reset Button.

Note: Be certain to turn the heater switch on the front panel of the instrument to the

ON position. Turn the coolant control switch to ON if an external chiller is used.

Note: Once a program has been entered into the controller it may be reused by

pressing the Run/Hold button to run the program again.

After the Test is Complete 1. Stop the Temperature Controller by pressing HOLD on the RUN/HOLD button on the

controller, then turn the Heater Switch to the OFF position. 2. Press the Auto/Man button to place the controller in manual mode. 3. Use the Up/Down keys to change the output power percentage to 0.0%. 4. Turn the Timer switch on the front panel of the instrument to OFF. 5. Stop the motor by turning the Motor Switch to the OFF position. 6. Turn off the Pump switch. 7. Release the pressure. Verify that the Pump Switch is in the OFF position and OPEN the

Pressure Release Valve all the way. Warning: When the temperature of the sample is above 212°F, leave at least 500

psig on the sample during cool-down. 8. Start cooling the cylinder by placing the Coolant Switch to the ON position. 9. After the cell has cooled and all of the pressure has been relieved, the test cell must be

drained of oil. Turn the Air Control valve to the AIR/EXHAUST position and OPEN the


Pressure Release valve. OPEN the Air-to-Cylinder valve. When air is heard exhausting from the vent, the cylinder is blown down.

10. Close the Air-to-Cylinder valve. Wait for the hissing to stop. 11. Close the Pressure Release valve and return the Air Control valve to the OFF position. 12. Turn off the Master switch. 13. Remove the sample thermocouple from the cell and remove the test cell plug. 14. Carefully lift the potentiometer mechanism and slurry cup out of the test cell using the

appropriate bails. The cup should be immersed immediately in a container of cold water, after which the slurry should be removed from the cup before hardening.

Remove the Control Console Assembly. See Control Console Removal. 2. Remove the valve handles, screws, and nuts supporting the valve bodies, the air control

valve, and top plate. 3. Remove the top plate from the unit. 4. Remove the high pressure valves. Replace the valve(s).

Air Pressure Regulator Adjustment The air pressure regulator is located at the left front of the consistometer, behind the front cover. The adjustment may be performed by hand. The adjustment is required if the pump will not pressurize the test cell to a desired pressure during a thickening time test. 1. Remove the front cover from the consistometer. 2. Turn the air pressure regulator knob clockwise to increase the discharge of air pressure.

Oil Reservoir Drain/Fill Procedure 1. Remove the front cover from the consistometer. 2. Attach a flexible hose from the oil reservoir drain valve to a convenient container used

for discarding the mineral oil. The reservoir holds approximately 2 quarts/liters of oil. 3. Open the oil reservoir drain valve. 4. Turn the AIR CONTROL valve to the AIR/FILL position and be ready to close the oil

reservoir drain valve when the reservoir is empty. 5. Remove the fill plug from the top of the oil reservoir. 6. Using a funnel, fill the reservoir with approximately 2 quarts/liters of clean mineral oil. 7. Replace the oil fill plug. 8. Replace the front cover.

Slurry Cup Potentiometer Service The slurry cup potentiometer (Pot. Mech.) is the resistive device that proportionally measures the torque on the API paddle during a thickening time test. The torque is measured with a wound resistor and a calibrated torsion spring. The torque is proportional to the deflection of the spring. The resistance is measured via the contact pins through the wall of the cylinder. Refer to drawing 07-0539 for assistance while completing the procedures below.


Resistor Replacement

1. Remove Shaft Bearing Retainer and Contact Arm. 2. Remove the old resistor using care to prevent damage to the slot. 3. Position the new resistor straight side down and with equal overlap beyond the contact

strips. 4. Seat the resistor firmly in the slot using a flat piece of wood. The top surface of the

resistor must be level. 5. Use a hardened rod (shank of drill bit) to rub the top surface of the resistor. This

burnishes the top of the resistor so that the contact arm will slide smoothly. 6. Rotate the contact arm by hand. Affirm that the arm makes contact with the resistor over

the full range of travel. If necessary, adjust the arm by bending it up or down. 7. Adjust the position of the Stop Arm, if necessary, to obtain full travel of the contact arm. 8. Replace the Shaft Bearing Retainer and check the potentiometer with the calibration

device. Torsion Spring Replacement

1. Remove Shaft Bearing Retainer and Contact Arm. 2. Remove the old Torsion Spring. 3. Install the new spring. Note that the spring winds tighter as the center shaft is turned

counterclockwise. 4. Replace the Contact Arm. 5. Loosen three screws on bottom of potentiometer. Do not remove. 6. Rotate Spring Adjuster until slack is taken out of spring and Contact Arm aligns with

first Contact Strip. Tighten screws. 7. Rotate the Contact Arm. Affirm that the spring does not bind or rub on the base below

the spring. 8. Replace the Shaft Bearing Retainer and check the potentiometer with the calibration

device. 9. To calibrate the potentiometer, see the Calibration Section of this manual. Potentiometer Bearing Service

1. Remove the Shaft Bearing Retainer and the Phillips Retaining Screw. 2. Remove the shaft bearing. 3. Loosen the set screws and slide the Stop Arm from the Spring Sleeve. 4. Remove the three set screws from the Frame. Remove the Spring Adjuster, the Spring

Adjuster Clamp, and the Spring Sleeve from the Frame. 5. Remove the two bearings and replace, if necessary. 6. Replace the Spring Sleeve and three set screws in the Spring Clamp. 7. Replace the Stop Arm and position it correctly before tightening the two set screws. 8. Replace the Shaft Bearing Retainer. 9. To calibrate the potentiometer see the Calibration Section of this manual.


Circuit Breaker And Fuses The Consistometer is protected with a combination of a Circuit Breaker and Fuses. The inlet 240 VAC or 120 VAC (120 VAC Option) is fused with a 2 AMP cartridge fuse. The 240 VAC voltage is stepped-down with a transformer to 120 VAC to operate all the instrumentation, solenoid valves, etc. in the Consistometer. The 120 VAC instrument power is fused with the MAIN POWER SWITCH on the Console panel. This power switch is also a Circuit Breaker. Reset the circuit breaker by turning off the switch, then on. The cause for failure for the fuses/circuit breaker must be corrected before attempting to operate the Consistometer again. The DC Motor Control Circuit also has two fuses that protect the motor circuit from overloading. The Line fuse is a BUSS ABC 6 and the Armature fuse is a BUSS MDA .50. The cause for failure of these fuses must be corrected before attempting to operate the motor again. The fuses are located at the rear of the instrument near the power cord. The instrument should be unplugged from the electrical outlet before attempting to change the fuses.

Motor Removal and Service Note: The DC motor uses brushes that must be checked every 600 hours by the user.

The brushes should be replaced when their length is less than ¼” (7 mm). 1. Remove the motor bracket mounting screws. 2. Remove the magnetic drive belt. 3. Remove the motor. Note the polarity of the DC power connections. 4. Remove the brushes from the motor and inspect for wear. Replace the brushes if

necessary. 5. Lubricate the gear head on the motor with oil. SAE #50 - Non-detergent oil is

recommended for use in this gear head. 6. Remove the oil plug and fill until oil is observed at the hole. Check the oil level every 4-5

months or every 600 hours of operation.

Motor Control Circuit Adjustments The motor control circuit does not require any service operations for normal use. The following information is presented if the control circuit is replaced and requires adjustments. There are three adjustment potentiometers on the control circuit. These adjustment points are labeled MIN, MAX, and REG. The adjustments are performed with the belt removed from the motor pulley. A digital voltmeter and a digital tachometer are necessary for these adjustments.

Note: The following adjustments involve high DC voltages. Only qualified personnel

should attempt these adjustments. In most cases, the factory adjustments are adequate on a new control circuit.


Warning: When measuring the motor speed, use caution to avoid the exposed electrical terminals, belt drives, and other potentially dangerous components within the unit.

1. Turn the MIN pot. fully counterclockwise, and turn the external speed adjustment pot. to

the minimum speed position. The motor should be stopped. 2. Turn the external speed adjustment pot. fully clockwise. 3. Using a digital voltmeter, adjust MAX and REG pots until the following voltages are

measured. Adjust MAX until 3.7 VDC is measured across terminals S1 & S2. Adjust REG until 112 VDC is measured across terminals A1 & A2.

4. Using a digital tachometer, adjust the external speed adjustment pot., until motor speed is 150 RPM (API Spec. 10).

High Pressure Pump Service The High Pressure Pump used in the consistometer is an air-driven pump that uses mineral oil as a pressurizing medium. The pressure of the input air supply to the pump controls the outlet pressure of the pump. An air regulator and an electric solenoid valve on the air supply line control the input air supply pressure. As the air pressure to the pump is increased, the outlet fluid pressure from the pump increases. Service to the pump consists of the installation of seal kits available from Chandler Engineering.

1. Remove the pump from the system. 2. All parts removed from the pump should be cleaned in a suitable degreasing agent. 3. Inspect all moving parts for scratches or wear. Damaged parts must be replaced. 4. Replace all O-Rings when the pump is re-assembled. Air Drive Section

1. Disassemble the Air Drive section of the pump. Note: Care should be taken to prevent the spring behind the air piston from

escaping. 2. Remove all O-Rings from the assembly and replace with O-Rings from kit. 3. The air piston, air barrel, cycling valve and sleeve should be re-lubricated on assembly

with silicon grease. 4. Torque the tie rod nuts evenly to 50 inch-pounds. Hydraulic Section

1. Disassemble the Hydraulic section of the pump. 2. Remove all O-Rings from the assembly and replace with O-Rings from kit. 3. Use the following torque values during reassembly:

Inlet Check Valve: 125 ft.lbs. Outlet Check Valve: 50 ft.lbs.


Calibration Procedures Consistency Display Calibration

No calibration is required. Model 7050 Temperature Controller Calibration

No calibration is normally required. Refer to the Model 7050 Manual for detailed instructions for operating the temperature controller. The calibration of the temperature controller may be checked using a thermocouple calibrator available from Chandler Engineering (p/n C09216). Temperature Controller Thermocouple

The thermocouple cannot actually be calibrated. However, the calibration can be checked. If the thermocouple calibration check shows that the thermocouple is reading out of tolerance, it should be replaced. See API Specification 10 for thermocouple calibration requirements. The calibration of the thermocouple can be checked using a thermocouple calibrator available from Chandler Engineering (p/n C09216). Timer

The calibration of the timer can be checked using a certified stopwatch. See API Specification 10 for timer calibration requirements. Potentiometer Mechanism Calibration

If the resistor or torsion spring on the potentiometer is changed, the potentiometer will need to be calibrated. Refer to drawing 07-0539 for assistance while completing the steps below. 1. Connect the potentiometer calibration device to the connector on the rear of the control

console. 2. Load the potentiometer with 400 grams. Tap on the calibrator until full deflection of the

spring is achieved. The display should read 100 Bc. 3. If the display does not read 100 Bc, adjust the value by turning the calibration screw

labeled as RECORDER SPAN on the rear of the control console. 4. When the display has been adjusted to read 100 Bc, remove the weights from the

calibrator. 5. The hook of the calibrator weighs 50 grams and should provide a reading on the display

of 9 Bc. 6. If the display does not read 9 Bc, the potentiometer mechanism requires adjustment. To

adjust, perform the following steps: a. Loosen the 3 recessed screws on the bottom of the potentiometer mechanism. b. On the top of the potentiometer mechanism, slightly move part 07-0065, the

spring adjuster (see drawing). c. Tighten the screws on the bottom of the potentiometer mechanism.

7. Replace the potentiometer in the calibrator and repeat steps 2-6 until both the 100 Bc and 9 Bc values are reading correctly.

Model 7716HPHT CONSISTOMETERA Critical Tool for Oil Well Drilling and Cementing

The Model 7716 Bench-Top Consistometer enables mobile and remote cement testing laboratories with very limited space to perform the fundamentally necessary testing of cement thickening time. This instrument is capable of testing cement thickening behavior in accordance with most API Spec 10A testing schedules.

Engineering Excellence for Long-term Performance

Chandler Engineering renowned manufacturing and field service experience is evident throughout the design of the Model 7716. This small, rugged instrument employs many of the design features of our full-sized consistometers in order to provide years of reliable service.

Operational Simplicity

The Model 7716 Bench-Top Consistometer is simple to operate with all of the operational controls conveniently located on the front panel alongside visible indications of thickening time, pressure and temperature. The slurry cup is designed so that closure, heating and pressurization can be achieved quickly.

The programmable temperature controller is equipped with proprietary Chandler Engineering firmware that accurately controls the rate of temperature rise of the slurry. Throughout the test, the built-in chart recorder tracks the temperature and cement consistency.

Once the user-set consistency is reached, an alarm will sound to alert the operator when the test is completed. The automatic shutdown feature of the instrument will turn off the motor, heater and timer as well as turn on the cooling water.

Operation can be further simplified by addition of the optional Model 5270 Data Acquisition and Control System which consists of interface electronics and custom software. To maximize system reliability, the software is purposefully designed to run on a stand-alone computer. The Model 5720 software can acquire test data as well as upload test protocols to multiple compatible Chandler Engineering instruments.

The usefulness of the Model 7716 Consistometer is not limited to the testing of cement thickening time. It can also be used to prepare slurries for other tests such as measuring free water content, testing for fluid loss or rheological properties and viscosity.

This instrument is capable of testing cement thickening behavior in accordance with most API Spec 10A testing schedules.

Engineering Excellence for Long-term Performance

Chandler Engineering’s renowned manufacturing and field service experience is evident throughout the design of the Model 7720. This small, rugged instrument employs many of the design features of our full-sized consistometers in order to provide years of reliable service.

A constant speed slurry cup drive rotates the cup at the required 150 rpm thereby improving testing accuracy and consistency. The drive’s reliability is maximized by use of a magnetic coupling system to connect the drive motor to the cup. The slurry cup is the same highly reliable design as is found in our other consistometers. The manual pressure control system is both simple to use and reliable. An automatic pressure control system is optional.
