While Sullair has built into this compressor a com-
prehensive array of controls and indicators to as-
sure you that it is operating properly, you will want to
recognize and interpret the reading which will call for

PURPOSE
Pushing in this switch, found adjacent to the controller,
cuts all AC outputs from the latter and de--energizes
the starter. A fault message (E STOP) is displayed by
the Supervisor until the button is pulled out and the "O"
pad is depressed.
Depress to turn the compressor ON.
Depress to turn the compressor OFF and reset the com-
mon fault circuit.
To select between continuos (HAND) operation and au-
tomatic stop/start (AUTO) operation. Shuts off compres-
sor automatically after the compressor runs unloaded for
a specified time (ranging from 3--60 minutes [T1]). Re-
starts compressor when the pressure switch trips to the
reload setting. Dual control is enabled by pressing the
"AUTO" pad.
Records cumulative hours of compressor operation;
useful for planning and logging service schedules.
Continually monitors service line air pressure. It is lo-
cated on dry side of receiver downstream from check
valve.
Continually monitors receiver/sump pressure at vari-
ous load and/or unloaded conditions.
Monitors temperature of the air leaving the compressor
unit. For both air and water--cooled compressors, the
normal reading should be approximately 180_F to
205_F (82_C to 96_C ).
Indicates when the air filter element change is required.
The gauge shows the red zone when drop through the
filter is excessive. The compressor must be running full
load for an accurate indication.
Indicates when a fluid filter element change is required.
It shows red when the pressure drop through the filter is
excessive.
Indicates when separator element change is required.
Shows red when the pressure drop through the filter is
excessive. The compressor must be running full load
for an accurate indication.
Indicates when the starter is receiving power.
Indicates when compressor is in operation.
Indicates when compressor is in auto mode.
service or indicate the beginning of a malfunction.
Before starting your Sullair compressor, read this
