- standard controller
The pressure dew-point is displayed on the display of the control panel. When the dew-point displayed is equal to or better than -40°C
(-40°F) PDP the dryer will switch into energy saving mode and stop cycling, resulting in zero purge, but no interruption in ow. When
the dew-point degrades to -39°C (-40°F) or higher, then the dryer will restart cycling ensuring the dew-point is maintained at or better
than -40°C (-40°F).
If during normal operation, the unit fails to achieve dew-point (degrades above -30°C (-22°F )) the dewpoint alarm output will be
indicated on the front screen and the remote alarm output will activate.
The set levels for the ES and dewpoint alarm are adjustable and can be accessed by carefully removing the front bezel to expose the
PLC and adjustment buttons.
Hold buttons A & B down for 8 seconds to access the menu shown on page 17 display 8.
