Final pressure switch
The pressure switch shuts off the compressor automatically
when the selected final pressure is reached. The final
pressure switch is already adjusted to the corresponding cut-
out pressure.
The pressure can be adjusted with the upper adjusting screw
as follows:
Increasing cut-out pressure:
Turn the adjusting screw clockwise
Reducing cut-out pressure:
Turn the adjusting screw anti-clockwise
Adjust the pressure switch in steps of a quarter turn.
Restart the compressor after every adjustment step to verify the actual cut-out pressure.
Example settings:
Note
Do not adjust the final pressure switch to the safety valve pressure. The final pressure switch
has to be adjusted to min. 10 bar below the safety valve pressure. Otherwise, the safety valve
can open during operation. This considerably reduces the life of the safety valve.
