Routine commissioning

Danger
Make sure before commissioning that nobody is in
the danger zone of the motor/screw compressor.
After completion of work: Verify that all safety
devices have been refitted and that all tools have
been removed.
Only operate the screw compressor unit with
closed access panels.
For routine commissioning, proceed as follows:
Check oil level in the pressure reservoir (see also
•
chapter 6.4).
Open shut-off valves between the screw
•
compressor, reservoir and pipe.
Switch on the power supply master switch.
•
After the power supply was switched on, all LEDs
•
on the compressor control GD Pilot MK light up for a
display test. The fault shown on the display [FAULT
POWER LOSS] must be acknowledged before the
unit can be started. To this end, press the
acknowledgement push-button [Θ] (- 4 - Fig. 16).
After the acknowledgement, the message [READY
•
TO START] appears on the display, unless another
fault is present.
Press START button [ I ] (- 2 - Fig. 16).
