10.Operation
When running, the compressor is controlled directly by the pressure switch. This disconnects the power
supply to the motor when the pressure inside the sump reaches the value that has been set on the
pressure switch (10 bar for single stage compressors, 11 bar for dual stage compressors or 13 bar for
special applications) and reconnects the power supply when the pressure inside the sump falls by
approximately 2 bar in relation to the maximum pressure allowed. This specific setting is defined during
testing according to customer specifications.
WARNING:
•
This reciprocating compressor should be made to operate for 60% of running time.
•
Compressors incorporate a safety valve on the sump with a pressure setting that is equal to the
maximum operating pressure setting on the pressure switch. This is triggered in the event of a
pressure switch malfunction in order to vent excess air.
•
Never, under any circumstances whatsoever, adjust the compressor in order to exceed the
maximum pressure setting.
•
To avoid the risk of burns, do not touch the connecting hoses, cylinder head, motor, check valve
or any other parts of the compressor that may become hot while the compressor is running and
for some minutes after it has stopped.
