Remove the Program Module with fingers ONLY by pulling up on the tabs on each end of the Program Module.Do not use any mechanical tool to remove the Program Module or damage may occur.
3. Install the new Program Module onto the empty socket. The Module and socket are keyed so it can only be installed in the correct (seated) position.4. Locate small connector (2), near the upper right corner of the battery holder which has two wires coming from it.5. Separate connector (2) by pulling gently on the plug. This will disconnect the batteries from the Indicator II to prevent damage while changing the program module.Once the connector is separated, two pins will be seen on the part of the connector still attached to the circuit board.6. Use a screwdriver or paper clip to short these two pins together for at least 30 seconds. Reconnect the two halves of the two pin connector and push them together until they snap into place.This will reset the Indictor II microprocessor.7. Install the rear cover and the six screws.8. Turn the Indicator II ON and check for correct operation.Checking The Operation Of The 9U6701 Ultrasonic Wear Indicator II
The following procedure may be used to check the operation of the 9U6701 Indicator II and the 4C5485 Probe.The only components required for the test are the 9U6701 Indicator II, 4C5485 Probe, and 9U7981 Couplant.Perform all the procedures as shown in Operating Instructions for the 9U6701 Ultrasonic Wear Indicator II, in this publication.Instead of measuring undercarriage components, the 6.3 mm (.25 in) calibration disk should be measured and the MEASURED VALUE saved, and the MEMORY VALUE displays checked for accurate readings.Alternate Method For Checking The Operation Of The 9U6701 Ultrasonic Wear Indicator II
An alternate method is to measure a known thickness of undercarriage steel.1. Check the display of the undercarriage Storage locations for one machine. During this test, use all front panel keys to be sure they operate correctly. If the Indicator II does not operate properly during this test, refer to the topic Troubleshooting, in this publication.2. Next, test the Indicator II on actual undercarriage components. Correct measurements should appear on the MEASURED VALUE display without having to move the probe back and forth.3. Also check to see that measurements can be taken on very thick undercarriage components such as through track shoe grouser bars. If the Indicator II has trouble making any of these readings the gain may need to be adjusted.Refer to the topic Troubleshooting, in this publication, for the procedures to adjust the gain.This completes the test of the Indicator II.Troubleshooting
If the Indicator II does not operate properly, first check the battery voltage and recharge if needed, or replace them with new fully charged batteries.The battery voltage should be measured at the two pin connector beside the battery holder.To operate properly, the battery voltage must be at least 5.8 volts.Below this voltage the Indicator II will not turn ON.The display will flash if the voltage is below approximately 6.1 Volts.As
