SECTION 4 TEMPERATURE SETPOINTS
SECTION 4.1 CHANGING THE TEMPERATURE DISPLAY FROM FAHRENHEIT TO
CELSIUS
Locate SW1 on the main control board (see page 29) and move Dip Switch #1 to the on
position. All Fahrenheit temperature readings will be converted to Celsius.
NOTE: Because the unit is converting from
F to
C, the Celsius setpoint entered may be a
few degrees above or below the desired setpoint.
SECTION 4.2 MODIFYING THE PROCESS TEMPERATURE SETPOINT (PLASTIC
RESIN DRYING TEMPERATURE)
When the “TEMP” key is pressed, the display shows the current process setpoint and
allows the user to enter a new process setpoint.
Select the new setting, then press enter. The display will go back to the first screen.

Temperature.
NOTE: Dryer Exhaust temperature is displayed only if the
Pre-Cooler
option is purchased.
This allows the user to monitor the regeneration temperature, the Return air Temperature
and the Pre-Cooler Dryer Exhaust Temperature for trouble-shooting. You can return to the
First Screen by pressing the “RETURN” key. The regeneration temperature setpoin
t
cannot be modified and has been preset to provide your unit with an optimum regeneration
cycle. The Pre-Cooler Water Valve Control will monitor the temperature of the Pre-cooler
dryer exhaust temperature.
