2Rear Panel Control Problems
EMERGENCY STOP (E-Stop) Function
a) PROBABLE CAUSES:
1. Rear panel disconnect plug
2. Defective switch
3. Wiring back to the main electrical enclosure
b) POSSIBLE SOLUTIONS;
1. If the EMERGENCY STOP (E-STOP) - rear - does not respond:
-Verify that ALL other EMERGENCY STOP (E-STOP) buttons are pulled out
-Verify that the rear panel’s disconnect plug is indeed connected. The disconnect plug is to allow the
removal of the panel for dryer servicing
2. Defective EMERGENCY STOP (E-STOP) Switch
-Shut power off (main breaker) remove the rear panel and check switch using an OHM meter; replace
if defective
-Re-test
3. Wiring back to main electrical enclosure
-Shut power off to the ADS-464 dryer (main breaker)
-Open “disconnects” on terminal 16 and terminal 17 of TB1; These disconnects are located on the
bottom of the main electrical enclosure.
-Connect an OHM meter to the output side of terminal 16 and terminal 17 of TB1
-Push in the Emergency Stop (E-Stop) button (opening the switch)
-Does the previous test show that there is a switch closure opening?
- If “YES,” refer to section 3a
- If “NO,” refer to section 3b
3a) Wiring from the Emergency Stop button to the main electrical enclosure is okay.
