4.1 GENERAL INFORMATION
The IMT CAS80R Hydraulic compressor has
a comprehensive array of controls and
indicators (see
Figure 4-1
). Understanding
the correct operation of the system will help
you to understand and recognize when it is
operating optimally. The information in the
Operation Section will help the operator to
recognize and interpret the readings, which
will call for service or indicate the beginning
of a malfunction.
WARNING
Before starting, performing maintenance,
or replacing parts, relieve the entire system
pressure by opening a service valve which
will vent all pressure to the atmosphere:
remove all electrical power.
IMPORTANT
Before starting the IMT CAS80R
compressor, read this section
thoroughly and familiarize
yourself with the controls and
indicators - their purpose, location
and use.
SECTION 4:
OPERATION
4.2 PURPOSE OF CONTROLS
CONTROL OR INDICATOR PURPOSE
Discharge Air Pressure
(Pressure Gauge) Continuously monitors service line discharge air temperature. Will activate shut-
down if over-pressure occurs.
Discharge Air Temperature
(Temperature Gauge) Continuously monitors service line discharge temperature. Will activate shutdown if
over-temperature occurs.
Hour Meter Gauge
(Operation Hours) Indicates accumulated hours of operation for planning and logging service sched-
ules.
Reset Button To reset latch-in relay in event of over-pressure or over-temperature.
Oil Fill/Level Plug To check/fill compressor oil level.
Minimum Pressure Check
Valve Maintains minimum operating pressure and prevents back flow when unloaded/
shutdown.
Pressure Regulator Controls operating pressure.
Inlet Solenoid Valve Opens/closes inlet valve in response to pressure regulator.
Air Inlet Valve Opens/closes in response to air demand and acts as check valve upon unload/shut-
down to prevent oil blow back into air filter.
Hydraulic Pressure Relief
Valve Relieves hydraulic pressure to return line in event of hydraulic over-pressure condi-
tion.
Hydraulic Solenoid Valve Responds to on/off switch 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.
