- Check wiring; refer to ADS-464 Main Panel Wiring Diagram
- Re-Test
7. “DRUM FAULT” Message
PLC (PROGRAMMABLE LOGIC CONTROLLER) MESSAGE “DRUM FAULT”
a. PROBABLE CAUSE;
1. Stop motion detector module or sensor. With control voltage “ON” (green push-button), use the pendant
control in “LOAD POSITION” to rotate the tumbler.
Note input #0, 10 on the PLC, stop the tumbler and wait for device’s latched relay to de-energize. The
time from when the tumbler stopped to the relay de- energizing should be 15-20 seconds.
- If the de-energizing time is satisfactory, the unit is operating correctly
- Check circiut wiring, and Re-Test (refer to ADS-464 Main Panel Wiring Diagram)
- If the de-energizing time is incorrect:
- Adjust the “time adjust” on the stop motion detector module and re-test
If the input # 0, 10 on the PLC is not on after several rotations of the tumbler:
- Check fuse 2 and replace if necessary.
- Rotate the tumbler using the pendant control in “LOAD POSITION.” Does the module’s L.E.D.
respond?
- If “YES,” adjust the “sense time” until the L.E.D. (light emitting diode) stays on for 15-20 seconds
after tumbler stops, then refer to section 1 above
- If “NO,” check:
- Inductive proximity sensor for damage
- Sensor distance from targets is 3/16’. The proximity sensor is located in the same area as the
tumbler junction box.
- Inductive proximity adjustment
- Tumbler target
- Stop motion detector module
