Auto Start Function
The auto start function allows operating the compressor
optionally in automatic or semi-automatic mode by turning
the selector switch.
Semi-Automatic Operation:
Start the compressor by pushing the Start button. The
compressor automatically shuts off when final pressure is
reached. To restart the compressor, push the Start button
again. The unit can be shut down at any time during
operation by pushing the Stop button.
Automatic Operation:
Start the compressor only once by pushing the Start button. The Start button lights up and the unit
automatically shuts off when final pressure is reached. If outlet pressure decreases below the
selected minimum pressure, the unit automatically restarts.
Note
i
The compressor can not be started manually during automatic operation.
To enable a manual start, shut off automatic operation by pushing the Stop button (Start button
lamp goes out). Now turn selector switch to semi-automatic mode and start the compressor with
the Start button.
Adjust re-start pressure (minimum filling pressure)
The pressure switch for start pressure is located after the
pressure maintaining valve. The pressure can be adjusted
with the upper adjusting screw.
Increasing re-start pressure: turn adjusting screw clockwise
Reducing re-start pressure: turn adjusting screw anti-
clockwise
Adjust pressure switch in steps of a quarter turn. Check
settings after every adjustment step.
