8.1 First commissioning
DANGER
The rotational direction of the motor can
only be checked with the casing open.
Rotating parts 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
screw compressor!
•
Be careful of rotating parts!
•
Keep a sufficient distance from rotating
machine parts!
•
Wear ear protectors
•
Always operate system with the casing
closed except when performing this test.
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
When the compressor system is connected to a
power source for the first time, always check
the drive direction of the drive motor!
When the compressor system is connected to a
power source for the first time, always check
the drive direction of the drive motor! With a
wrong direction of rotation, shut down the unit
immediately by pressing the emergency STOP
button(-1- Fig. 18) (not the


- STOP button),
otherwise the compressor may be seriously
damaged, even during short periods of
operation.
The compressor unit is fully assembled at the factory. It
can be directly connected to the compressed air supply
system with a flexible connection.
Carry out the first commissioning as follows:
•
If transport safety devices are present, remove
them.
•
Fill the pressure reservoir with oil up to the
“maximum oil level” mark (this applies to
compressor systems which are delivered without oil)
(for oil filling see Sections 7.3.1 and 10.13).
•
Check the oil level in the pressure reservoir
(also see Section 7.3.1 Fig. 15)
•
Check of the fan motor circuit breaker setting (only
L23RS-L29RS) (also see Section 7.3.1)
•
Check the control transformer setting (also see
Section 7.3.2).
•
Check and tighten all connecting terminals on the
electrical control system.
•
Open the isolating valves between the screw
compressor, reservoir and pipework.
•
Turn on main switch to the power supply.
•
When the unit has been switched on for the first
time, the
POWER LOSS
fault appears on the display.
This fault must be acknowledged with (Fig. 20,
page 34). The system is supplied with the display
language set to English. To choose another
language, see Section 9.5.1.
•
After acknowledging the fault the message [READY
TO START] appears in the display as long as no
other fault is present.
•
The target system pressure set at the factory (upper
and lower switching points) is stored in the GD Pilot
compressor control and is set according to the
corresponding compressor pressure type (see
nameplate Fig. 1, page 2, stage pressures =
maximum positive operating pressure). Chapters
9.5.2 / 9.5.3 describe how you check these settings
or change the values.
•
To check the drive direction, temporarily open the
enclosure, prescribed drive motor direction see
(- 1 - Fig. 16). The prescribed fan direction, see the
rotation arrow on the fan (- 3 - Fig. 19). The
rotational direction of the fan can be checked by the
direction of the cooling air flow, see (-1-, -2- Fig. 19).
•
Press the Start button

I
(Fig. 20, page 34) and
immediately check the direction of rotation.
•
If the direction is incorrect, immediately press the
EM-STOP button (-1- Fig. 18) and correct the
direction of rotation.
•
Next, check the control transformer output voltages
while operating under load (see Chapter 10.9).
