maintenance
2 Separator Differential Displays pressure drop across the separator element for determining
when to maintenance
3 Temperature Displays temperature of air end oil leaving the air end for monitoring
4 Line Pressure Displays the line pressure (air leaving the minimum pressure valve) for
monitoring
5 Sump Pressure Displays pressure in the sump tank for monitoring
6 Power On Light Amber light which turns on when power to the compressor is available
7 Selector Switch 3-position switch to select suitable mode of operation and to turn the

5.2 MODES OF OPERATION
The selector switch allows the operator to choose between RUN and AUTO modes of operation for the
compressor. The functions of these modes are explained below.
5.2.1 RUN MODE
Selecting the RUN mode of operation will keep the motor running while the compressor is loaded and
unloaded. This mode of operation is best used in high air demand systems to minimize motor starts.
5.2.2 AUTO MODE
Selecting the AUTO mode of operation allows the motor to shut off during periods of little to no air usage, as
controlled by the pressure switch. The compressor will automatically restart once line pressure drops to the
load setting of the pressure switch.
