OPERATION

4.1 GENERAL
While Sullair has built into this compressor a com-
prehensive array of controls and indicators to
assure you that it is operating properly, you will
want to recognize and interpret the reading which
will call for service or indicate the beginning of a
malfunction. Before starting your Sullair compres-
sor, read this section thoroughly and familiarize
yourself with the controls and indicators - their pur-
pose, location and use.

4.2 PURPOSE OF CONTROLS
CONTROL OR INDICATOR
PURPOSE
ENGINE SWITCH
The engine switch is used to both energize the compressor’s
electrical system and engage the engine/starter. The rotary
type switch works similar to an automotive key switch; it turns
in a clockwise direction with “off” being the first position, “igni-
tion” the second and “start” being the third position. It also has
a built-in anti-restart device that protects the starter fromen-
gaging while the engine is running. The switch must be turned
back to the “off” position before the engine can be re-started.
When re-starting the compressor,make sure receiver
tank pressure has blown down to (10 psig 0.7 bar) or
less. More than 0.7 bar (10 psig ) can put extra load on
the starter.
NOTE
VOLTMETER
Monitors the condition of the batteries and the charging
circuit. The normal reading is 24 to 28 volts.
AIR PRESSURE GAUGE
Continually monitors the pressure inside the receiver tank at
various load and unload conditions.
ENGINE WATER TEMPERATURE GAUGE
Monitors the temperature of the engine water. The normal
operating temperature should read approximately 160°F to
210°F (71°C to 99°C ).
EMS (ENGINE MONITORING SYSTEM)
Depicts system-related diagnostics. Can be used for system
performance monitoring.
COMPRESSOR DISCHARGE TEMPERATURE
GAUGE
Monitors the temperature of the air/fluid mixture leaving the
compressor unit. The normal reading should be approximately
200°F to 230°F (93°C to 110°C).
SYSTEM PRESSURE SWITCH
Prevents starter engagement when the air system is pressur-
ized.
FLUID LEVEL SIGHT GLASS
Monitors the fluid level in the sump. Proper level is always
visible in the sight glass. Check the level when the compres-
sor is shut down.
COMPRESSOR DISCHARGE TEMPERATURE
Opens the electrical circuit to shut down the compressor
when the discharge temperature reaches 265°F (124°C) or
250°F (121°C) for interstage.
REDUCING REGULATOR VALVE
Provides regulated air pressure to the inlet valve and engine
speed control to open the inlet valve and move engine gover-
nor to full speed with warm-up valve in the“run” position.
BACK PRESSURE REGULATING VALVE
Provides an air signal to the inlet valve and engine speed
cylinder to close the inlet valve and reduce engine speed to
control air delivery according to demand.
