Rear 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

Wiring from the Emergency Stop button to the main electrical enclosure is okay.
