Purge Control
Panel
LCD Display
The control panel LCD display is back lighted to facilitate viewing in low light ambient
conditions. The back light is activated when any keypad switch is pressed. However, if the
operator simply wishes to activate the back light the “STATUS” switch is the preferred choice
since it has no effect on purge operation. If after 30 minutes of no further keypad activity the
back light will automatically go off.
NOTE : The LCD back light automatically activates during any “FAULT” condition and will
remain activated until the “FAULT STATUS” is reset (see page 45 for additional
information on fault indications).
Keypad Switches
All purge unit functions are controlled via a multi -function 16-switch keypad and a LCD display
located on the front of the unit’s electrical control box. (See pages 31 through 40 for further
information on the functioning of the various keypad switches)
NOTE: Some keypad switches have multiple functions, the same switch may serve a
different purpose depending upon the mode you are in (i.e. the ADAPTIVE
mode switch is also a compressor test switch and a number 1 switch).
