6.”DRUM FAULT MESSAGE” Malfunction

a)PROBABLE CAUSES;

1a) Stop Motion Detector Module or Sensor.

2a) Wiring back to Main Electrical Enclosure

b)POSSIBLE SOLUTIONS;

Open the Main Electrical Enclosure locate input #0, 10 on the PLC (Programmable Logic Controller). With control voltage “ON” (“GREEN” Push-Button), use the pendant to rotate the tumbler. Notice a L.E.D. (light emitting diode) on as the tumbler (basket) is rotating.

If the L.E.D. is off, refer to paragraph 6 (section a) above.

1b) If the L.E.D. (light emitting diode) is off:

Check Fuse #2; replace if necessary.

Rotate the tumbler using the pendant control, and adjust the stop.

Does the module’s L.E.D. (light emitting diode) respond?

If yes, adjust the “Time Adjust” until the LED is on during rotation 12 to 15 seconds after.

If no, check:

Inductive Proximity Sensor for Damage
