�� Max Bottle Diameter: 6.0 inches

Pin Positioning Chart

The chart below shows the diameter range for each pin

position.


Vise Jaws For Rectangular Bottles

Special vise jaws are frequently supplied for rectangular and

unusual shaped bottles. These special jaws are required in

order to insure that the bottle is centered under the cap

chuck.

See example below.

Adjusting The 1614 Universal Vise

When pins are used for clamping the test sample, the vise

should be tightened just enough to hold the bottle but not so

tight as to distort the shape of the bottle.

By noting the position of the handle crank and returning to

this position when changing samples, the user can rapidly

load and unload the vise.


About The Chuck Height Adjuster

The Height Adjuster was designed to position the cap

chuck at a convenient height for loading and unloading test

samples while providing for the minimum amount of

vertical chuck motion for the operator.

Positioning The Chuck With The Height Adjuster

Loosen the Height Adjuster Thumb Screw and position the

cap chuck approximately 1" above the bottle cap when using

the 1506A beverage clamp or 1" above the position that

allows the test bottle to be loaded into the 1614 vise or other

tooling systems. (See picture below)

Keypad Torque Display

A Guide To Using Model 1502 Torqo Understanding the Control Panel � 28

Torque Display

This four-digit display is used to report test results and

provide a communication link between the user and the

software.

LED Indicators

The six LED indicators on the control panel are used as

status indicators for the system.

At a glance the user can determine what test mode is

selected, what unit of measure is selected and whether or not

the system is ready to perform a test.

The Removal, Removal & Incremental, Removal & Bridge,

Batch and Reverse Ratchet LED's serve only one purpose

and that is to indicate what has been selected in the Current Machine. (See Using Machine Numbers)

The Metric LED serves two purposes.

First it serves as an indicator when lit, that the unit of

measure is Metric not English.

Secondly it serves as an end of test status indicator.


Blinking Metric LED

This LED will blink when a test has been completed

indicating that the data that is currently displayed must

either be saved or discarded before another test can be

performed. (See Logging Test Results)

Keypad

The Torqo keypad was designed with a two-color overlay to

make it as user friendly as possible.

It serves as the primary communication link between the

user and the system software.

The picture to the left shows the keypad with a typical three

function key high-lighted.

The number keys are used for inputting numerical values

when programming the Torqo.

The words printed in Black above the numbers are the

primary key functions and are used when the system is in the

Ready State.

The words printed in Red beneath the numbers are the

secondary key functions and are accessed by pressing the

[Mode] key first.

Do not use sharp objects to depress the keys on the Keypad.

Damage to the Keypad will occur.


Quick Start

What’s Inside

This chapter contains a button-by-button, step-by-step

procedure to help the user become familiar with the

operation of the Torqo by actually performing a Removal

Torque Test.

Performing A Test

With the system turned on and initialized as described in the

System Power Up section of this manual the front panel

should appear as shown.

By default, the Removal Torque Test Mode will be selected.

The torque display should now read zero.

Zeroing the Display

If the display does not read zero, press [Clear] before

proceeding with this sample test sequence.

The display must never be zeroed when the cap chuck is connected to a bottle in the holding fixture.

This action can result in an offset that will affect the measurements.

A Guide To Using Model 1502 Torqo Quick Start � 31

Now load the bottle to be tested into the holding fixture and

clamp the bottle in accordance with the procedure described

in the Bottle and Cap Tooling section of this manual.

Encage the cap chuck by gently pressing the drive extension

rod down until the chuck engages the cap.

Now press [Open]

Observe the display. The torque will increase until the

system detects that the cap has released. The drive will then

reverse and re-apply the cap to a preset torque value.

The re-application torque is normally set by the user and the

procedure for setting it is described in the section of this

manual titled Setting the Re-application Torque in the

chapter titled Programming a Removal Test.

The Re-application Torque used in this sample test was set

by default when the system was initialized. The chart below

shows the default values for the different size Torqo's.

Mdl #

Max. Torque

(In-lbs)

Application Torque

(25%)

1502-10 10 2.50

1502-20 20 5.00

1502-30 30 7.50

1502-40 40 10.00

1502-50 50 12.50

1502-70 70 17.50

1502-100 100 25.00


After re-applying the cap, the drive will relax to zero and

the removal torque will be displayed. (See example)

Note the Orange Metric LED is Blinking. This indicates

that the test has been completed.

Before another test can be started the results of the last test

must either be discarded by pressing [Clear] or saved in

memory by pressing [Next].

For this Quick Start example press [Next] and this will save

the data in memory for printing in the next step.

Now press [Print] then [1], this will produce a hard copy of

the stored test results when a printer is connected to the

system.

The Torqo is programmed to produce a number of different

printed reports, refer to the section titled Using the Torqo Printer for more information on this subject.

be selected and a step-by-step procedure for selecting one.

Description Of The Testing Modes

Provisions have been made for a number of special test

modes in the standard Torqo.

�� Removal Torque Test Mode

�� Removal & Incremental Torque Test Mode

�� Removal & Bridge Torque Test Mode

�� Reverse Ratchet Torque Test Mode

�� Batch Test Mode

A chapter is devoted to the programming of each of these

modes however a brief description of each of these modes

can be found below.

A Guide To Using Model 1502 Torqo Test Modes � 34

Removal Torque Test Mode

This mode is used to measure the Removal Torque on

conventional threaded bottles and caps.

Rotating the cap in the counter-clockwise direction until the

cap releases performs the test.

Removal & Incremental Test Mode

This mode is used to measure the removal torque as well as

the Incremental Torque in a single test cycle.


cap releases and then re-applying the cap to a position that is

6 degrees past the initial starting position performs this test.

Removal & Bridge Test Mode

This mode is used to measure the removal torque as well as

the Bridge Torque in a single test cycle.


cap releases and then continuing to drive until the Bridges

on the tamper evident band are broken performs this test.

Reverse Ratchet Test Mode

This mode is used to measure the torque required to rotate a

child resistant closure in the free running state. (i.e. No

vertical down force)

This test is performed by rotating a child resistant cap in the

counter-clockwise direction for 2 complete revolutions

while looking for and storing the highest measured torque

value.


Batch Test Mode

This test mode enables the user to keep track of the removal

torque measurements by capping head number.

Selecting A Test Mode

A test mode can be selected by following the procedure

described below.

Press [Mode]

At this time a Blinking LED on the front panel will indicate

the current mode of operation.

Now by continuing to press the [Mode] key the Blinking

LED will advance from one mode to another.

following condition exists.

Data has already been stored in memory for this machine

number and therefore the mode can not be changed.

The Torqo software does not allow the user to combine data from different types of tests in the same data file. (i.e. Same Machine Number)


There are two 2 remedies for this problem.

1. Clear memory for the current machine number.

(See Chapter 17: Clearing Memory)

2. Change machine number and then select the desired

mode. (See Chapter 18: Using Machine Numbers)

Programming the Min Torque

What's Inside

This chapter contains a description of the Min Torque and a

button-by-button procedure for programming the Min

torque.

Min Torque Description

The Min Torque is a value of torque that must be reached

during a test in order for the system to consider the torque

reading valid.

This feature is provided as a method of preventing the

system from recording an erroneous torque during a removal

torque test.

Erroneous torques can be generated from slippage in the

tooling due to the mechanical tolerances of the test sample

and from improper use of the Torqo.

This value is programmed as a percent of the full-scale

torque of the system.

The default value for min torque is 10% of full-scale torque.

10% was selected as a reasonable value because most

measuring devices should not be used consistently in the

bottom 10% of their range. However the torqo, unlike

analog systems, does not lose its accuracy at the low end of

its range and therefore with proper attention to the cap and

bottle tooling measurements can be made below 10%.

A Guide To Using Model 1502 Torqo Programming the Min Torque � 86

During the testing process, the Torqo looks for a torque that

is greater than the Min Torque.

The system will drive 180° in search of this value.

If a value greater than Min Torque is not found then the

error message E 3 will be displayed.

Inputting a Min Torque

The Min Torque can be changed by the following procedure.

Press [Mode] then [Min-TQ]


the display. The default value is 010.0.

Key in the desired value and press [Next] twice to accept

the entry and return to the Ready State.

Gold Bottle Calibration Check

What's Inside

This chapter describes the Gold Bottle and the procedure for

using it to verify the calibration of the Torqo.

Gold Bottle Description

The Model 1612 Gold Bottle is used to quickly verify the

calibration and operational repeatability of the Model 1502

series torqo's. This bottle is pre-set at the factory to a

customer specified torque value.

Each Gold Bottle is labeled with its exact torque rating.

Since the cap torque of this bottle is the torque produced by

a permanent magnet assembly, the value will always be the

same. Therefore when tested on the Torqo, the measured

value should always repeat unless something has been

damaged.

The bottle is normally supplied with the customers cap so

that the customers Torqo Cap Chuck can be used in the

testing process.

These Gold Bottles are readily available and their torque can

be certified on an annual basis.

A Guide To Using Model 1502 Torqo Gold Bottle Calibration Check � 88

Using the Gold Bottle

The Gold Bottle must be tested in the Removal Mode and

since the cap cannot be removed, it therefore cannot be re-

applied.

The following procedure must be used when testing it.

Press [Mode] repeatedly until the Removal LED indicator is

blinking and then press [Next] to terminate the selection

process.

Press [Set-TQ] and key in the value 00.50 and then press

[Next] to terminate the input process.

Insert the Gold Bottle into the bottle holding tooling.

Press [Clear] to zero the display.

Now engage the Cap Chuck.

Press [Open]

Observe the Removal Torque when the Metric LED

indicator is flashing.

The torque reading on the display should now match the

reading on Gold Bottle Label.

The allowable variation is computed by adding together the tolerance on the bottle and the +/- .5% FS tolerance of the machine.

For example:

If the Gold Bottle has a Torque Setting of 12.00 +/- .2 in-lbs

and the Torqo is a 30 in-lb machine then the allowable

variation is +/- .35 in-lbs. (i.e. .2 +.15 = .35)

System Calibration

What's Inside

This chapter is intended to acquaint the user with the

required Calibration Equipment, the Calibration Verification

Process, the process for performing a User Calibration and

the procedure for Selecting the Calibration to be used.

General Calibration Information

The Torqo is supplied with a factory Calibration that is

burned into read-only memory. This is done so that the user

will always have a backup calibration when an incorrect user

calibration is performed.

Calibration Frequency

Checking the calibration of the Torqo at least twice a year is recommended when the system is used frequently.

Required Calibration Equipment

The following list of equipment is required to perform a

Torqo Calibration. When ordering this equipment please

provide the Model Number and Serial Number of the

machine that the equipment will be used on.

A Guide To Using Model 1502 Torqo System Calibration � 90

1. Calibration Beam (Disk)

2. Calibration Fixture

3. Calibration Weight Set

Calibration Beam

The calibration beam is a disk with a diameter of precisely

8.000 inches. Each disk is serialized and the actual diameter

is stamped on the bottom. The beam is supplied as an

assembly of the following parts.

1. Calibration Disk (C-19935)

2. Calibration Cables (A-21013)

Calibration Fixture

The calibration fixture is supplied as an assembly of the

following parts.

1. Calibration Bracket (D-19936)

2. Cable Pulleys (B-19870)

3. Retain Rings (N5100-25)

Calibration Weight Set

The calibration weight set consists of three weights that are

selected to provide a torque of 25%, 50% and 75% of the

full-scale torque of the Torqo.

(See chart below)


Calibration Weight Chart

The required weight in lbs for producing a specific torque

can be computed by dividing the desired torque value by 4,

since 4 inches is the Radius of the calibration beam.

This chart shows the weights that Mesa supplies when a

calibration kit is purchased. The 100% value is obtained by

combining the 25% and 75% weights

Selecting a Calibration to be Used

The currently selected calibration can be determined and

then changed by the following procedure.

Press [Mode] then [Mach] and observe the display.

The currently selected calibration identification number will

be displayed. (See table below)

�� 0 = No correction in use. (For Factory use only)

�� 1 = Factory Calibration in use.

�� 2 = User Calibration in use.

�� 3 = User Calibration in use and latched.


After performing a user Calibration, the number (3) will be automatically selected.

With the currently selected number displayed, Press the

[Limits] key to page through the setting numbers.

When the desired number is displayed, Press [Next] twice

to terminate the selection process.

Performing a Calibration Verification

This procedure is used to verify that the Torqo is in

calibration and to produce a hard copy of the measured

values when a Torqo Printer is connected to the system.

The first step in this procedure is to install the Calibration

Fixture on the Torqo.

Installing the Calibration Fixture

The calibration fixture mounts on the front of the Torqo as

shown in the picture.

To install the fixture, loosen the two 5/16 Socket Head Cap

Screws that can be accessed from under the base plate and

then insert the fixture between the base plate and the Torqo

cover. Now re-tighten the bolts.

(Wrench Size ¼ " Hex)

The next step is to install the calibration beam.


Installing the Calibration Beam

The beam is installed by first removing any bottle holding

tooling and then carefully placing the beam on top of the spindle cap.

Screws are provided for holding the beam in place.

(Qty 2 x .250-20 x 1" Skt Hd Cap Screws)

(Wrench size 3/16 " Hex.)

Creating a Calibration Verification Chart

With a Torqo Printer connected, a Calibration Verification

Chart can be created as the calibration check is being

performed.

If the system is not connected to a printer, the measured values should be manually recorded for analysis at the conclusion of this procedure.

Press [Mode] then [Cal] to commence the process. With the

depression of the cal button the following information will

be printed. This Header not only identifies the Torqo but

also provides information about which calibration is

All readings should be within the specified tolerance range.


Performing a User Calibration

Once again the calibration fixture and beam must be

installed on the Torqo before the calibration procedure can

begin.

Calibration Methodology

The calibration procedure consists of entering on the display

a known value of torque that will be applied by the weight

and beam. Then applying this value by hanging the weight

on the calibration cable. At this time the software will

compute the difference between the entered value and the

value applied by the weight. This difference will become the

correction value for this specific point and will be stored in

memory. Once all the points ( i.e. 25%, 50%, 75% and

100% in both the clockwise and counter-clockwise

direction) have been measured the software will compute a

correction curve to be applied during the measuring process.

Entering the Calibration Mode

The Calibration Mode is entered by first turning the

instrument off and then re-powering the system with the

[Cal] key depressed

The front panel will now appear as pictured.

The word HELP indicates that the system is in the calibrate

mode and ready for user input.


Before commencing the calibration procedure all previous

user calibrations should be erased and the system zeroed.

Erasing all Previous User Calibrations

Press [Mode], this will erase all previous calibrations and

return to the HELP screen.

Zeroing the Torqo in the Calibration Mode

Press [Cal] then [Next]; this will automatically zero the

system prior to commencing the calibration. Once again the

software will return to the HELP screen.

The following calibration procedure will begin by inputting

25%, then 50%, then 75% and finally 100% in the clockwise

direction and then repeating the procedure in the counter-

clockwise direction.

Care must be taken when entering values to insure that they have been keyed in correctly.


Entering Calibration Torques

Now key in the following numbers [0] [2] [5] [0].

The first 0 indicates that the direction will be clockwise.

The 25.0 indicates that the applied torque will be 25%.

Now press [Next]

Observe the display, when the next key was selected above

the decimal point was removed indicating that the torque

load can now be applied.

Place the 25% weight on the right hand calibration cable and

the 0250 count on the display will decrease to a small

number. (i.e. Usually less than 0050) Now when the display

becomes steady press [Next] and the value will be stored.

The display should now have returned to the HELP screen

and the 25% weight should be removed.




Now press [Next]

Once again the decimal point will be gone and now the 50%

weight should be placed on the right hand cable. The 0500

count on the display will decrease usually to a value less

than 0050. Now when the displayed reading becomes steady

press [Next].







Now press [Next]


weight should be placed on the right hand cable. The 0750



press [Next].



After calibrating at 25%, 50% and 75% in the clockwise

direction, key in the following numbers [2] [0] [0] [0].

The 2 indicates that the direction will be clockwise.


Now press [Next].

Once again the decimal point will be gone and now the

100% weight should be placed on the right hand cable. The

2000 count on the display will decrease usually to a value

less than 2050. Now when the displayed reading becomes

steady press [Next].

The 100% weight value is obtained by combining the 25%

weight and the 75% weight.



The 1 indicates that the direction will be counter clockwise.


Now press [Next]

Place the 25% weight on the left hand calibration cable and

the 1250 count on the display will decrease to a small

number. (i.e. Usually less than 1050) Now when the display

becomes steady press [Next] and the value will be stored.






Now press [Next]


weight should be placed on the left hand cable. The 1500



press [Next].







Now press [Next]


weight should be placed on the left hand cable. The 1750



press [Next].






Now press [Next].

Once again the decimal point will be gone and now the

100% weight should be placed on the left hand cable. The

3000 count on the display will decrease usually to a value

less than 3050. Now when the displayed reading becomes

steady press [Next].



Press [Next] twice to terminate this procedure and return to

the ready state. As the calibration procedure is terminated,

the software computes the correction curve for this user

calibration.


At this time it is a good idea to printout a report of the

complete system setup and calibration information.

This report shows both the factory calibration information

and the user calibration information.

Observe the actual correction values that are shown in this

report.

The new correction values should not be significantly different than the factory calibration values.

About the Child Resistant Option

This option enables the Torqo to provide a pre-settable down

force for push and turn caps.

An air supply with the ability to provide a minimum of 30

PSI is required.

Once connected to the air, the down force can be set to the

required force for a given application.

Connecting the Air Supply

The air supply connects to the air filter on the rear of the

tower.

This connection is a � NPT thread.

Both the air filter and regulator are designed for a maximum

of 100 PSI however the Force Gauge is limited to 30 PSI.

A Guide To Using Model 1502 Torqo Child Resistant Cap Option � 107

Adjusting the Down Force

Once connected, the Air Control Knob should be adjusted to

provide the required amount of down force.

Observe the down force gauge on the front of the tower

cover while adjusting the knob.

In most cases, a down force of 15 t0 20 lbs will open a child

resistant closure.

Adjusting the Down Force Foot

The Down Force Foot applies the force on the cap by

pressing down on the Drive Shaft Bearing when the Down

Force Switch is actuated.


To adjust the foot put the Down Force switch in the up

position and then place the sample to be tested in the bottle

holding fixture.

Now position the Cap Chuck on the cap by lowering the

drive shaft.

Pivot the Down Force Foot over the top of the Drive Shaft

Bearing and adjust for approximately 1/16 of an inch of

clearance. (i.e. the thickness of a quarter)

Loosening the Foot Position Shaft Clamp and sliding the

Foot Support Shaft up or down and then retightening the

clamp makes this adjustment.

Operating the Child Resistant Mechanism

Once the mechanism has been adjusted, a sample is tested

by pivoting the foot into position and actuating the Down

Force Switch.

At the conclusion of the test cycle, move the switch to the up

position and pivot the foot to the rear.

Repeat this procedure for the next sample.


Key lock Option

What's Inside

This chapter describes the features and use of the key lock

option.

Key lock Option Description

The key lock option adds a key actuated switch on the rear

panel of drive tower.

This option was designed to prevent the inadvertent altering

of the Torqo setup.

Using the Key lock Option

The key lock switch has two positions.

In the Program position, this option is not in use and

therefore all of the torqo features can be accessed through

the control panel.

In the Run position, the user is not permitted to change the

Mode, Limits or Setup features.

If a setup key is pressed, a three-beep alarm will be sounded

to indicate that this selection cannot be performed.

A Guide To Using Model 1502 Torqo Key lock Option � 111

Multi-Speed Option

What's Inside

This chapter describes the use of the Multi-Speed Option.

Multi-Speed Option Description

The multi-speed option adds a selector switch on the rear

panel of drive tower.

This option was designed specifically for testing bottle caps

with tamper evident bands. The increased speed of the drive

provides for a cleaner tear of the material that connects the

band to the cap.

This option may also be used for performing more rapid

testing. However one must be careful, when using the

system in this manner, to make sure that the increased speed

is not distorting the measurements.

The Speed Selector Switch enables the user to select the

following four speeds.

Position 1: 1 RPM

Position 2: 2 RPM

Position 3: 4 RPM

Position 4: 6 RPM

A Guide To Using Model 1502 Torqo Multi-Speed Option � 112

When a speed other than 1 RPM is selected, it will be used

in all the Test Modes with the exception of the Removal &

Incremental Mode.

The Removal & Incremental Mode is an industry standard

and cannot be changed.

This test is always performed at 1 RPM

When a high speed is selected, the system will drive at the

selected speed for the first 75% of a closing cycle and then

automatically revert to 1 RPM for the remaining 25%.

Using the Multi-Speed Option

To use this option the operator just has to put the Speed

Selector in the desired position and test in the normal

manner.

As mentioned previously, performing Removal tests at

speeds greater than 1 RPM may distort the data.

To insure the accuracy of the measurements, one should first

perform the tests at 1 RPM and then repeat the tests at a

greater RPM. The results should then be compared for

accuracy and repeatability.

Trouble Shooting

What's Inside

This section is provided to help the user solve some of the

minor problems that may occur with a Torqo.

Contacting Mesa Laboratories, Inc.

If you are unable to solve your problems with the system

after trying the suggestions in this manual then please call

are service department at 303-987-8000.

Before calling Mesa please obtain the serial number

from the label on the back of the control instrument and if

possible obtain the software version number by pressing

[Total] then [Display] and observing the torque readout.

If you have a printer connected to the system the software

version can be obtained by pressing [Total] then [Display] then [Print].

Trouble Shooting the System

If your Torqo does not appear to be performing properly, the

following procedures can be used to find and correct some

of the more common problems.

A Guide To Using Model 1502 Torqo Trouble Shooting � 118

Restoring the Factory Defaults

Restoring the factory defaults will correct errors that have

been made when programming the system.

Performing a Soft Reset

Press [Total] then [Mode]

This will return the system to the factory default state.

Re-initializing the System

The Torqo like all microprocessor-controlled systems can

experience a computer crash.

Blinking LED's

When a crash occurs, the LED's on the Control Panel will

Blink in a random pattern.

This problem is usually caused by an interruption in power

and can be avoided by using a Surge Protector.

Performing a Hard Reset

This procedure will re-initialize the microprocessor and reset

all factory settings.

The Hard Reset is performed by first turning the

instrument off and then re-powering the system with the

[Display] key depressed


Erratic System Behavior

The Torqo relies on a battery backed memory chip to store

program settings, date and time settings and test results. If

your system has lost the ability to maintain its settings, the

battery in the memory chip may have degraded. This will

result in Erratic System Behavior.

The life expectancy of this device is from 5 to 10 years.

However its life is affected by the amount of time that the

system is turned off because this is when the battery is in

use.

It is not a good idea to stock these devices as backup because their life is measured from date of manufacture.

L's on the Display

When the memory chip has degraded, the Torque readout

will frequently display the letter L in one or more digit

locations.

Checking the Memory Chip

The memory chip can be checked by setting the Date and

Time and then turning the system Off for 30 minutes. If

the battery backup is working the system date and time will

be correct.

A new memory chip can be purchased from Mesa and it

will be supplied with detailed instructions for installing it.


Torqo Drive Problems

The Torqo drive motor, drive electronics and drive belt

system are time proven, high reliability devices.

Most drive related problems can be remedied by checking

the following items.

Checking the Power

1. Verify that the power switch is on. (0=Off, 1=On)

2. Verify that the power cord is seated in the AC Input.

3. Verify that the power cord is plugged into a good outlet.

4. Verify the connection of the Drive cable at both ends.

5. If the drive still does not operate check the fuse.

Checking the Fuse

1. Turn the Power Switch off.

2. Remove the AC power cord.

3. With a small flat bladed screwdriver, pry open cover with a

twisting motion.

4. Note the direction of the arrow and then pull the white fuse

holder out of the module.

5. Check the fuse and replace if required. (MDL 1½ for

120VAC and MDL ¾. for 240VAC)


Checking the Drive Belt

A broken drive belt can be detected by attempting to rotate

the drive shaft by hand.

If the Torqo is a standard Model 1502 without the Multi-

Speed option the shaft should not turn more than a few

degrees when rotated by hand.

If the Torqo has the multi-speed option, the shaft will turn

but with a great deal of resistance.

The drive belt is broken when the shaft turns freely in either of the two cases described above.

Replacing the Belt

1. Unscrew the Drive Shaft Knob.

2. Remove the Cover Screws.

3. Remove the Cover by lifting it up and over the

drive shaft.

The drive belt system in this picture is a multi-speed unit

however the procedure for removing a belt, determining the

size of a belt and installing a new belt is basically the same

in all units.

1. To remove the belt, loosen the screws on the motor

plate to take the tension off the belt and then

remove the belt.

2. To install the belt, place it around the sprockets,

slide the motor plate to tension the belt and then

tighten the motor plate screws.


Determining the Belt Size

The best way to determine the correct belt size for a system

is to lay the broken belt on a flat service and count the

number of drive pins.

Then contact the factory for the correct part number.

Checking the DC Power

1. Put the AC Drive Power Switch in the Off

position.

2. Remove the 12 screws that hold the rear panel on

the tower.

3. Carefully tilt the top of rear panel out as shown in

the picture.

4. Now put the AC Drive Power Switch in the On

position.

5. Observe LED01: It should be on whenever the

tower is energized. This indicates that the +5 vdc

supply is on.

Checking for the Clock Pulses

The clock pulses come from the control instrument to the

drive tower whenever the drive motor is turned on.

With the tower energized, press [Open] and observe the

LED02.

LED02 will be fully on when the motor is not running and

will dim slightly when the drive is turned on. (It is actually

blinking quickly)


If all of the above checks do not indicate where the problem lies please contact the factory for assistance.


Maintenance and Cleaning

What's Inside

This chapter describes the recommended maintenance and

cleaning procedures for a Torqo and its tooling.

General Information

The Torqo is designed to operate for many years with the

minimum amount maintenance.

However the Torqo, like any precision measuring tool,

should be periodically checked for accuracy. (See System

Calibration)

The calibration of the Torqo should be checked at least

twice a year.

A protective cover can be supplied for those applications

where washdowns are frequently performed.

General Maintenance

Keep the system clean, for this will make the use of the

Torqo more pleasurable.

Disconnect the power to the system when cleaning.

A Guide To Using Model 1502 Torqo Maintenance and Cleaning � 125

Clean the exterior with a mild detergent and a soft cloth.

Avoid abrasive cleaners that may scratch the lens on the

torque display and the keypad.

Cleaning the Tooling

The functionality of the bottle holding tooling and the

chucks should be periodically checked.

All bottle tooling should move smoothly and easily.

Chucks should slip onto caps with the minimul amount of

force.

Cleaning the 1506A Bottle Clamp

This tool is made from corrosion resisting materials and

therefore it can be fully submerged in hot soapy water for

cleaning.

Remove the fixture by unscrewing the 2 mounting screws

and lifting straight up.

Make sure the center hole is clean before re-installing the

fixture.

Cleaning the 1614 Pin Vise

This tool can also be submerged in hot soapy water but care

should be taken to throughly dry the lead screw and then it

should be lubricated with a light oil.
