• Retest; verify that the signal is operational
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 module’s 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
