4.0 DRUM FAULT MESSAGE Malfunction
a. PROBABLE CAUSES;
1) Stop Motion Detector module or sensor
2) Wiring back to main electrical enclosure
b. PROBABLE SOLUTIONS;
1) 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 (basket).
Notice a L.E.D. (light emitting diode) on as the tumbler (basket) is rotating.
If the L.E.D. (light emitting diode) is off, refer to section #1a
1a) If the LED (light emitting diode) is off:
Check Fuse 2; replace if necessary
Rotate the tumbler (basket) using the pendant control, and adjust the stop
Does the modules L.E.D. respond?
If yes, adjust the Time Adjust until the L.E.D. (light emitting diode) is on during rotation 15 to
20 seconds after the tumbler (basket) stops
If NO, check:
Inductive proximity sensor is located in the same area as the tumbler (basket) junction box
Inductive proximity mechanical adjustment
The target that is attached to the outside of the basket
Stop motion detector module
Circuit wiring; refer to ADS-464 Main Panel Wiring Diagram, ADS-464 Tumbler Junction
Box Wiring Diagram
1b) If the L.E.D. (light emitting diode) is constantly ON
If YES, the stop motion detector is defective
If NO, check:
Inductive proximity sensor for damage. The proximity sensor is located in the same area as
the tumbler (basket) junction box
Inductive proximity mechanical adjustment
