2.5 Description of Controls
2.5.1 Compressor Controls
The W3 Series compressor may operate with the following two controls:
Automatic Start
–
Stop Control:
This is the standard control type for all single pressure compressor systems. With this type of control, once the
compressor is manually started, it will run till it reaches the high set pressure where is will automatically stop (the
pressure where the motor will cut-out); after the pressure drops to the low set-pressure (the pressure where the motor
will cut in), it will automatically re-start. This control system is standard on all single pressure compressors.
Drain Control:
W3 Series compressors can be automatically drained by automatic drain valves. These drain valves
are controlled by 3 way Solenoid Valve which is normally closed. This solenoid valve supplies or
cuts the control air on the drain valves, thus letting them to open or close. The solenoid valve itself
is controlled by a timer installed in the electrical panel. The dual time adjustment on this timer
allows to adjust the time period (t1~7 min) which the solenoid will remain energised (=the drain
valve will remain closed), and the duration( t2 ~ 6 seconds) during which the solenoid will be de-
energised (=the drain valve will open and perform the drain function).
Important !
Do not change the factory settings of the drain times and durations. Consult the factory if you need to
change the settings.
