8.1 First commissioning
DANGER
Rotating parts may lead to injuries,
e.g., cutting of finger or hand.
•
Always operate system with the casing
closed.
CAUTION
Damages during transport may impair
safety!
•
Before commissioning, every screw
compressor should be checked again
for damage and should be watched
during the first hour of operation.
NOTICE
The screw compressor is provided without
cooling water and may only be started after it
has properly been filled with water (also see
Chapter 7.4).
When storing the screw compressor system or
in the event of a longer period of downtime, if
there is the risk of frost ( t < 33.8°F) the cooling
water should be completely discharged
(compressor stage, coolers, system containers,
water filters, storage containers, RO unit, lines,
valves).
The screw compressor unit is completely factory-
assembled. It can be directly connected to the com-
pressed air mains by means of a flexible connection.
First commissioning is carried out as follows:
•
Remove transport guards, if fitted.
•
Check the water level in the pressure reservoir
(see also chapter 7.4) (Fig. 12)
•
Check settings of the fan motor protection switch
(see Chapter 7.3.1)
•
Check the setting of the control-power transformer
(see also chapter 7.3.2).
•
Check and re-tighten all connecting terminals of the
electrical control.
•
Open isolator 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.
•
The factory setting of the setpoint value for the
network pressure (upper and lower switching point)
is saved in the compressor control GD Pilot TS and
depends on the relevant pressure variant of the
compressor (see nameplate fig. 1, stage pressures
= maximum operating pressure). These settings can
be checked or changed in the compressor control
GD Pilot TS menu [Settings; Pressure range, p1]
(further information can be found in Section 5 of the
compressor control GD Pilot TS operating manual).
•
Next, check the control transformer output voltages
while operating under load (see Chapter 10.9).
Temperature start-up protection
The screw compressor unit will not start up if the
ambient temperature is lower than 35,6 °F.
8.2 Putting a decommissioned
compressor back into operation
Before commissioning the compressor all the electrical
and electronic components and units should be
checked for the ingress of water or condensation.
If the electronic control system was removed during
shut down, it must be re-installed.
Then proceed as described in chapter 8.1 'First
commissioning'.
