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 MLS-460 Main Panel Wiring Diagram, MLS-460 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
