Process Air Dew Point Display

Optional

The Process Air Dew Point meter indicates the current process air delivery moisture content. Standard dryers use a microprocessor-based controller for displaying dew point air temperature. The controller is a modular, self-contained unit removable from the mounting housing. All parameters are factory set and adjusted; normally, no field adjustment to the internal controls are necessary.

Note: No field adjustment is required. The dew point meter is meant for moisture indication only!

Setting the High Dew Point Alarm

The high dew point alarm setting is changed by pressing the up and down keys to input the alarm value. The factory setting for Alarm Value 1 (AL-1) is -10°F (-23°C).

Restoring the Process Air Dew Point Meter (E5CK) to Factory Setup

If the preset parameters on the controller have been tampered with and it no longer functions properly, call the Service Department. This controller is not meant to be modified.
