PENDANT ASSEMBLY

A. PENDANT ASSEMBLY DESCRIPTION

The pendant assembly is used on both the gas and steam model dryer. Within the pendant assembly there is a three (3) position selection switch used to tilt the dryer in the load tilted, unload tilted, or level position. When the load tilted or unload tilted selection is made, the load/unload door will open once the door signal has been received, and the dryer will tilt. The jog forward/jog reverse push buttons, when depressed individually, will cause the tumbler (basket) to turn clockwise (CW) for forward and counterclockwise (CCW) for reverse. If both push buttons are depressed together the jog feature is disabled due to the mechanical interlock with the pendant assembly. This feature is used as a safety device to prevent both drive motors from being energized in opposite directions.

The EMERGENCY STOP (E STOP) button is a push-to-stop and twist-to-release switch. When the E STOP button has been depressed the control power to the dryer is disabled. Voltage is still present at the dryer even though the EMERGENCY STOP (E STOP) has been depressed.
