4-5 Temperature Controller LED Indicators

Process Value Numeric LED

During normal operation, this red LED on the control displays the process temperature at the "To Process" thermocouple. It also lists parameters during setup and error messages if an error occurs.

Set Value Numeric LED

During normal operation, this green LED on the control displays the process set point you want the dryer to maintain. It also displays parameter and pre-set function values during setup.

Output LED

This orange LED lights when the control output energizes the process air heater.

Remote LED

This lights when remote operation occurs on dryers equipped with optional communications.

Shift LED

This orange LED lights if the optional Shift Set switch is closed. The process temperature

will be changed by the amount set in the value in the Level 1 parameters. To shift to a lower value, be sure to enter a negative value.

Auto-Tune LED

This orange LED flashes during the Auto-Tune sequence. The controller will automatically determine the proper P.I.D. values for the operating conditions. See Section 6-11.

Alarm One LED - High Temp Alarm

This lights when the process air temperature has risen more than 25°F [factory default] from the setpoint. The alarm relay in the PLC is energized when this LED is lit.The audible/visual alarm will sound if the dryer is so-equipped. All heaters turn off and the blowers stay on to cool the heaters. It is adjustable - see Section 5-5.

Alarm Two LED - Low Temp Alarm

This lights when the process air temperature drops more than 25°F [factory default] from the setpoint. The alarm relay in the PLC is energized when this LED is out. The audible/visual alarm will sound if the dryer is so-equipped. It is adjustable - see Section 5-5.
