Commissioning.
This should be undertaken by a technically competent person
With the generator installed as described earlier remove the front cover. Check that all the internal
components are securely located and have not moved during transit.
Open the air supply and turn the unit
ON.
Set the regulator on the Inlet Filter/Regulator to the desired
pressure.
Check that the cooling fans are operating and exhausting air out of the generator. Check that the cam on
the timer is rotating. Check that the red LED on the Temperature Control Boards is lit.
After a maximum of 2 minutes the cam timer valve should operate to change over the columns on the
PSA drier unit. This is accompanied by an audible rush of exhaust air from one of the exhaust ports.
Should this not happen the position of the Cam Follower will need adjusted. This is done by the adjusting
screw on the arm of the Cam Follower. (Note: - the 5/2 valve will not operate if the system pressure is
below 60 psig. If the system pressure has not reached 60 psig wait a few minutes until the next cycle.)
After a maximum time of 40 minutes the Catalytic Chambers should have reached temperature. When
this happens the relay on the Temperature Controllers will “click” and the LED's will go out. The heaters
will then cycle as required.
Do not touch any part of the Catalytic Chambers or Copper Lines, as they will be VERY hot.
