4-1 Controller Description and Operation

Identifying Control Panel Indicator Lights and Switches for the Standard Controller

Switches

System OFF/ON/START Switch. This switch energizes or de-energizes control power to the indicator panel and starts the dryer. (The controller can be energized without the dryer running.)

Indicator Lights

Alarm Light. This feature works in conjunction with the alarm horn to warn the operator of a high bed safety temperature, a regeneration heater fault, or a blower failure. This warning is reset by pressing the alarm silence button.

Process Air Temperature Controller

Our dryers use a microprocessor-based PID temperature controller for maintaining process air temperature. The controller is a modular, self-contained unit that can be removed from the mounting housing. All parameters except for the process air set point are factory set and adjusted; normally, no field adjustment to the internal controls is necessary.
