3.EMERGENCY STOP (E-Stop) SWITCH - PB6

If the EMERGENCY STOP (E-Stop) - pendant - does not respond:

a)PROBABLE CAUSES;

1a) Another EMERGENCY STOP (E-Stop) Button

2a) A Disconnect Plug

3a) Faulty Switch

4a) Wiring Back To TB1

b)POSSIBLE SOLUTIONS;

1b) Verify that ALL other EMERGENCY STOP (E-Stop) buttons are pushed in, and Retest.

2b) Verify that ALL of the Pendant’s disconnect plugs are indeed connected. The disconnect plugs are for removal of the Pendant arm for shipping.

3b With the control voltage off, open pendant assembly and check switch using an OHM meter; replace if defective.

4b) Locate terminal #14 and terminal #15 on TB1 on the bottom of the main electrical enclosure. Open their associated disconnects and place an OHM meter across these terminals. Push the EMERGENCY STOP (E-Stop) button in. Does the OHM meter respond.

If YES, wiring to TB1 is correct, check wiring on the main electrical panel, then retest.

If NO, wiring from the pendant to TB1 is incorrect. Check wiring using the appropriated wiring diagrams listed above, and retest.

F.TEMPERATURE SENSING

Introduction

There is one (1) temperature sensing and controlling device in the AD-464 located in the exhaust. The temperature sensing device is a RTD (Resistance Temperature Device), whose resistance changes with temperature. The temperature information from each RTD’s (Resistive Temperature Device) is forwarded to a respective 4 to 20 milliampere (4 to 20 mA) transmitter located on the Main Electrical Enclosure Panel. The converted signal is then connected PLC’s (Resistive Temperature Device) analog input module for further processing.
