2.0. 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
• Retest
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” (E-Stop) button to the main electrical enclosure is okay.
• Check wiring on Main Electrical Enclosure Panel (See Main Wiring Diagram)
• Retest
