2.8. Switching off the compressor
The compressor can be switched off locally pushing the OFF button or remotely opening the start/stop remote
contact (if a remote contact is connected to the appropriate terminals). In both cases, when the machine is
commanded OFF, the controller de-energizes all the relay outputs controlling the contactors as well as the solenoid
valve, thereby causing the compressor to stop in a turn off delay time (parameter P17 – default 15 s) .
When the motor is stopped, the control unit activates a safety restarting delay (parameter P16 - default 15 s) to
prevent the compressor from restarting with pressure in the inner tank when the ON button is pressed (or when
the remote start/stop contact is opened). Compressor restart is inhibited throughout the count down of the
restarting delay time.
The inhibition to restart is indicated by the flashing of LED x10. When the count down of the restating delay time
is over, LED x10 is turned off. At that point, it is possible to restart the compressor.
The following diagram provides an example of the operating cycle.
