5.1 GENERAL

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

read this section thoroughly and familiarize your-
self with the controls and indicators --- their pur-
pose, location and use.
PURPOSE
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 com-
pressor automatically after the compressor runs un-
loaded for a specified time (ranging from 15---30 min-
utes). Restarts compressor when the pressure switch
trips to the reload setting. Dual control is enabled by
placing the control switch in the "AUTO" position.
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 compres-
sor 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 re-
quired. 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 re-
quired. 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.
Monitors fluid level in the sump. The fluid must be vis-
ible in the glass. Check the level when the compressor
is shut down. Maximum fill level is the level of the fill
port, minimizing the risk of overfilling.
