Air Operations (SRS-40P)
Activating the compressor switch sends
power to the cooling fan and normally
closed terminal (87A) of the Bosch relay.
Power from the Bosch relay goes to the
hydraulic solenoid valve and speed control.
The compressor and speed control are acti-
vated any time the hydraulic system is
engaged and the compressor switch is on.
The compressor pumps air until the pressure
reaches 175 psi. The proportional compres-
sor inlet valve then shuts down and only
allows in sufficient air to maintain 175 psi.
This pressure will be maintained as long as
the air usage remains within the capacity of
the compressor. The inlet valve is controlled
by the compressors pneumatic control cir-
cuit. The air pressure is factory set and
needs no further adjustment. The pneumati-
cally controlled compressor is also protect-
ed by two switch gauges. If the air pressure
or oil temperature exceeds the preset val-
ues, the switch closes energizing the relay
coil which opens the normally closed switch
on the relay shutting off power to the
hydraulic solenoid and speed control.
Operating Notes:
This rotary screw compressor must not be
used for breathing air. To do so will cause
serious injury whether air is supplied direct
from the compressor source or to breathing
tanks for later use. Any and all liabilities for
damage or loss due to injuries, death
and/or property damage, including conse-
quential damages stemming from the use
of this compressor to supply breathing air
will be disclaimed by the manufacturer.
The use of this compressor as a booster
pump and/or to compress a medium other
than atmospheric air is strictly non-
approved and can result in equipment
damage and/or injury. Non-approved uses
will also void the warranty.
Never use plastic pipe or improperly rated
metal pipe. Improper piping materials can
burst and cause injury or property damage.
