Routine commissioning
WARNING
Rotating parts inside the unit may lead to
injuries, e.g., cutting of finger or hand.
•
Before commissioning make sure that no
one is located in the danger zone of the
motor/screw compressor!
•
After doing work: Check that all safety
equipment is reinstalled and that all
tools have been taken out!
•
Only operate the screw compressor with
the coverings closed!
For routine commissioning, proceed as follows:
•
Check the water level in the pressure reservoir
(see also chapter 7.4)
•
Open shut-off valves between the screw
compressor, reservoir and pipe.
•
Turn on the main power supply switch.
•
After the power supply was switched on, all LEDs
on the compressor control GD Pilot TS light up for a
display test. The fault shown on the display [power
supply fault] must be acknowledged in the fault
memory menu item prior to starting the unit. (The
display language can be set in the start screen
using the "globe icon".)
•
After the acknowledgement, the message [READY
TO START] appears on the display, unless another
fault is present.
•
Press START button [ I ] (- 2 - Fig. 15).
•
To switch off the compressor in the usual way use
the STOP button (-3- Fig. 15) and not the
emergency STOP button (-7- Fig. 15). After
shutdown the compressor has a run on time of
30 - 50 seconds (soft-stop). The time remaining is
counted down on the display.
Start-up protection of the electric motor
The screw compressor unit will not start up if the final
compression pressure is more than 14.5 PSI.
Temperature start-up protection
The screw compressor unit will not start up if the ambi-
ent temperature is lower than 35,6 °F.
