Sterling Plumbing Cabinet Series Dehumidifying Dryer 4-2Process Air Dew Point Display, OUT1, OUT2

4-2 Process Air Dew Point Display

The Dew Point display indicates the current process air delivery moisture content. The display uses a microprocessor-based controller for reading dew point air temperature. The controller is a modular, self-contained removable unit in the mounting housing. All parameters are factory-set and adjusted; no field adjustment to the internal controls is necessary. The high dew point alarm is also factory adjusted.

4-3 Process Air Temperature Controller

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

4-4 Identifying Temperature Controller LED Indicators

LED	Description
Indicator
Process Value	During normal operation, the process value (PV)
Numerical	numeric LED indicator displays the process
LED	temperature at the To Process thermocouple. It
	also lists parameters during setup and error
	messages if any errors occur.
Set Value	During normal operation, the set value (SV)
Numeric LED	numeric LED indicator displays the process set
	point you selected for the dryer. The dryer then
	maintains this set point temperature. This LED
	indicator also displays parameter and pre-set
	function values during setup.
OUT1	Lit when control output 1 turns on. The Out
	indicator lights when the controller signals the
	process heaters to be energized.
OUT2	Lit when control output 2 turns on. Not used in
	this application.
MANU	Lit when the manual operation mode is being
