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
