Version 2.2

The system is controlled by an electronic controller t-Log (4) which keeps the net pressure 
within programmable pressure limits by automatically loading and unloading the compressor 
in relation to air consumption.

Unloading:

If air consumption is less than the air delivered by the compressor, the net pressure 
Increases and reaches the upper limit of working pressure (unloading pressure). The 
controller (2) stops energize the solenoid valve (3), the valve opens, the air pressure from 
the separator tank (4) closes the damper (5) of the suction valve (1), and the compressor’s 
pneumatic system is unloaded through the throttle.

Loading:

When the net pressure decreases to the loading pressure, the controller (2) energizes the 
solenoid valve (3). Air pressure from the separator tank (4) is interrupted and the damper (5) 
opens. Air suction resumes and the compressor runs loaded.
