COMMISSIONING AND OPERATING
6.1
Initial commissioning
NOTICE
Material damage
Although every compressor has already under-
gone a test run in the factory and has undergone
a careful final inspection in dispatch, the possi-
bility of transport damage cannot be excluded.
➯
Before commissioning check the compres-
sor once more for damage and monitor it
during its initial operating hours.
➯
If the compressor is being connected to a
power supply network and started for the
first time, then dependent on the version,
the direction of rotation of the drive motor
and/or fans must be checked.
– Drive motor for non-
RS
compressors,
– Fan for
RS
compressors
Preparations
Check all electrical and electronic compo-
nents/devices for water ingress or condensate
formation, in case of complaints, contact Gard-
ner Denver.
If the compressor has been in storage for a
substantial period of time (up to 2 years), the
main switch must be switched on at least one
hour prior to starting. This ensures the operabil-
ity of the capacitors and prevents any damage
from occurring.
If the compressor has been stored for longer
than 2 years, consult Gardner Denver.
Carry out the initial commissioning as follows
1. Check the oil level.
2. Check the settings of the fan motor overload
switch.
3. Check the setting of the control transformer.
4. Check all the terminals of the electronic control
unit and tighten as necessary.
5. Switch on the main switch.
– All three LEDs on the control panel illumi-
nate.
6. Set the display language.
7. Set ambient pressure / altitude level for RS + e
8. Acknowledge faults indicated on the display.
– The message [Ready to Start] appears on
the display.
9. Check the factory setting of the pressure set-
points (minimum line pressure [Line Pres-
sure min.] and maximum [Line Pressure max.])
and readjust if necessary.
10.Ensure the external cooling water supply is ad-
equate (water-cooled compressor only).
11.Press start button < I >.
12.Check the direction of rotation of the drive mo-
tor (not RS compressors) or the fans (RS com-
pressors ). See the following descriptions.
13.Check the output voltages of the control trans-
former in load operation.
Check the direction of rotation of the drive
motor (not RS compressors )
DANGER
Risk of injury
The drive motor rotational direction can
only be checked if the clutch cover is de-
mounted.
➯
Before switching on, check that
there is nobody in the danger area!
➯
Maintain an adequate distance from
rotating machine parts!
➯
Wear ear defenders!
➯
Except for test runs, only operate
the compressor with the enclosure
closed.
