INJECTOR CALIBRATOR CD3 MAINTENANCE AND TROUBLESHOOTING
4.3.3 Adjusting Pulley cover Interlock
1. Adjust pulley cover up or down so that when
closed, the cover will push in the button on the
pulley cover interlock.
2. Adjust latch, if necessary, so that cover closes
completely and stays closed while calibrator is
operating.
4.3.4 Adjusting Optical Detector on Camshaft
The optical detector is mounted on a cross bar in the
rear under the pulley cover. The encoder wheel is a
thin disk which passes through a slot in the detector.
1. If the encoder wheel rubs the sides of the slot in
the detector, loosen the nuts holding the detector
to the cross bar.
2. Adjust the detector forward or back until the
encoder wheel rides through the center of the
slot.
4.3.5 Motor Starter Overload Relay Setting
1. Find the operating volts located on the nameplate
of the test stand.
2. Locate the FLA (Full Load Amps) and SF (Service
Factor) for the corresponding voltage (step 1),
which can be found on the main drive motor.
3. The minimum dial setting on the Motor Starter
Overload Relay is equal to the FLA value.
4. The maximum dial setting on the Motor Starter
Overload Relay is calculated by multiplying the
FLA value times the SF.
5. Set the A (Auto), H (Hand) switch to H (unlocked
position.
4.3.6 Changing Drive Belt
To change the drive belt, it is necessary to
disassemble some components. Proceed as follows:
1. Switch the On/Off Switch to the OFF position.
2. Open the pulley cover.
