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

-Circiut wiring; refer to ADS-464 main panel wiring diagram ADS-464 tumbler junction box wiring diagram
