6 COMMISSIONING AND
OPERATION
6.1 Initial commissioning
NOTICE
Property damage
Although every compressor has already
undergone a test run at the factory, and has
been checked thoroughly again prior to shipping,
the possibility of transport damage cannot be
eliminated.
➯
Check the compressor again for damage
before commissioning and observe it during
the first few hours of operation.
➯
If the compressor is connected to the power
grid again and started, the direction of
rotation of the drive motor and/or the fan
absolutely must be checked, depending on
the version.
– Drive motor for non-RS compressors
– Fans for RS compressors
Preparations
Check all electrical and electronic components
and devices for water that may have
penetrated or condensed. If any is found,
contact Gardner Denver.
If the compressor has been stored for an
extended period of time (up to 2 years), then
switch on the main disconnect switch at least
one hour prior to starting. This ensures that the
capacitors are functional and prevents them
from being damaged.
If the compressor has been stored for longer
than 2 years, consult Gardner Denver.
Perform initial commissioning as follows
1
Check the oil level.
2 Check the settings of the fan motor protection
switch.
3 Check the settings of the control transformer.
4 Check all connection terminals on the
electronic controller, and tighten if needed.
5 Switch on the main disconnect switch.
– All three LEDs on the control panel light up.
6 Set the display language.
7 Acknowledge the faults shown on the display.
– The message [Ready to start] appears on
the display.
8
Check the factory settings for target pressure
(minimum network pressure [min. network
pressure] and maximum network pressure
[max. network pressure] ) and adjust if
necessary.
9
Switch on the cooling water supply (for water-
cooled compressors only).
10
Press start button < I >.
11
Check the direction of rotation of the drive
motor (not RS compressors) or the fans (RS
compressors). See the following descriptions.
12
Check the output voltages of the control
transformer under load.
Check the direction of rotation of the drive
motor (not RS compressors )
DANGER
Risk of injury
The direction of rotation of the drive
motor can be checked only if the
coupling cover is removed.
➯
Before switching on, ensure that
there is no one in the hazard zone.
➯
Keep a safe distance away from
rotating parts of the machine.
➯
Wear hearing protection.
➯
Operate the compressor only when
the enclosure is closed, except for
test runs.
