D. PENDANT CONTROL MALFUNCTIONS

INTRODUCTION

There are four (4) electrical switches associated with the ADS-464 Pendant Assembly. These components are interfaced to TB1 of Main Electrical Enclosure through two (2) disconnects and two (2) junction boxes.

The Pendant Assembly is remote control for Loading or Unloading the ADS-464. The functions provided are:

•LOAD - LEVEL - UNLOAD

•TUMBLER REVERSE

•TUMBLER FORWARD

•“EMERGENCY STOP” (E-Stop)

The following information will provide a means to respond to “Pendant” malfunction, and to verify ALL its electrical signals. Refer to the following ADS-464 Pendant associated wiring diagrams for detailed assembly and wiring information.

1.0Pendant Electrical Components

•LOAD - Level - UNLOAD ------------------ A and B

•Tumbler Reverse Switch ----------------------- PB2

•Tumbler Forward Switch ---------------------- PB1

•“EMERGENCY STOP” (E-Stop) Switch -- PB6

There are two (2) normally open electrical switches associated with this switch function, that are actuated by three (3) position selector.

SEL A = LOAD

SEL B = UNLOAD

Once this switch is turned to “LOAD,” the dryer’s front doors will open, and depending upon system configuration, will either tilt back or remain level.

•If the ADS-464 was configured to UNLOAD from the front: Any time this switch is turned to “UNLOAD,” the dryers front doors will open, and its tumbler (basket) will tilt to the front.

•If the ADS-464 was configured to UNLOAD from the rear: Any time this switch is turned to “UNLOAD,” nothing will happen. ALL unloading functions will be transferred to the rear control panel.

•TUMBLER REVERSE “PENDANT” --- PB2

This push button comprises of one (1) normally open switch, and is mechanically interlock with the Tumbler Forward Push-Button.
