The BASE controller that regulates the compressor based on the pressure settings and readings of the
pressure sensor.
Loading
As long as the working pressure is below the preset maximum, the solenoid valve is energised, allowing
control air to the unloader: the inlet valve opens completely and the unloading valve closes completely.
The compressor will run fully loaded (100% output).
Unloading
When the working pressure reaches the maximum limit, the solenoid valve is de-energised, venting the
control air: the inlet valve closes completely and the unloading valve opens completely. The compressor
will run unloaded (0% output).
The G 7, G11 and G 15 are equipped with the BASE controller, an intelligent controller that will stop the
compressor after a variable period of unloaded operation using following algorithm:
If the unloading pressure is reached after the first start and if there is no air consumption, the
compressor will run unloaded during 2 minutes and then stop.
If there is a pressure request within the first 2 minutes after being stopped, the controller is expecting
a higher air consumption: the next time the unit will stop after 5 minutes of unloaded operation.
If there is no pressure request earlier than 2 minutes after being stopped, the controller is expecting a
lower air consumption: the next time again it stops after 2 minutes of unloaded operation.
If the compressor is stopped manually, it stops after 2 minutes of unloaded operation.
The compressor will automatically restart when the net pressure drops to the minimum limit.
