Becoming familiar with the functional
instrumentation, as given in
Section 4.2,
Purpose of Controls
, will help the operator

OPERATION
4.2 PURPOSE OF CONTROLS
CONTROL OR INDICATOR
PURPOSE
Discharge Air Pressure
Screen
Continuously monitors service line discharge air pressure. Will activate shut-
down if over-pressure occurs.
Discharge Air Temperature
Screen
Continuously monitors service line discharge temperature. Will activate shut-
down if over-temperature occurs.
Hour Meter Screen
Indicates accumulated hours of operation for planning and logging service
schedules.
Fault Reset Screen
Fault message appears if over temperature or over pressure condition is
encountered. Button must be pressed to clear.
Oil Fill/Level Plug
Check/fill compressor oil level.
Minimum Pressure/Check
Valve
Maintains minimum operating pressure and prevents back flow when
unloaded/shutdown.
Pressure Transducer
Controls operating pressure; prevents loaded start.
Inlet Solenoid Valve
Opens/closes inlet valve in response to pressure transducer.
Air Inlet Valve
Opens/closes in response to air demand and acts as check valve upon unload/
shutdown to prevent oil blow back into filter.
Hydraulic Pressure Relief
Valve
Relieves hydraulic pressure to return line in event of hydraulic over-pressure
condition.
Hydraulic Solenoid Valve
Responds to activation circuit to direct flow to compressor motor or to return
line.
Air Pressure Relief Valve
Opens sump pressure to atmosphere in case of air over-pressure condition.
