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.

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

 

used.

 

 

STOP

Lit when control operation has been stopped. Not

 

used in this application.

 

 

RMT

Lit during remote operation. Not used in this

 

application.

 

 

AT

Flashes during auto-tuning.

 

 

SUB1

Lit when the output function assigned to auxiliary

 

output 1 turns on.
