7.7 Setting the motor overload protection switch
Electrical diagram in chapter 13.3 gives the setting values for the motor overload protection switch.
In direct on-line starting, the current for the fan motor is fed via the motor overload protection
switch.
To prevent the motor overload protection switch from being triggered by voltage fluctuations,
temperature influences or component tolerances, the setting can be higher than the rated
motor current.
➤ Check the motor overload protection switch setting.
The overload protection switch shuts the machine down despite being correctly set?
➤ Contact KAESER Service.
7.8 Evacuating the machine
Before initial start-up the compressor must be evacuated and then filled with gas.
After a long transport or storage, the protective gas may have escaped, see also chapter 6.3.
➤ Perform a leak test before commissioning. If required, consult with the manufacturer.
Evacuation
1. Close the user's shut-off valves at the inlet and outlet ends.
2. Evacuate the machine to a minimum vacuum of ≤5 mbar using the hose couplings of the evac‐
uation connections, see chapter 13.1.
3. Open the user's inlet and outlet shut-off valves.
Filling with gas
1. Fill the machine with gas via the evacuation connections hose couplings as described in chap‐
7.9 Starting the machine for the first time
Precondition No personnel are working on the machine
All access doors are closed.
All removable panels in place and secured.
1. Open the user's inlet and outlet shut-off valves.
2. Switch on the power supply isolating device.
After the controller has carried out a self-test, the green
Control voltage LED is lit continuously.
3. If required:
Change the display language as described in chapter 7.11.
4. Press the «ON »key.
The drive motor runs up and after a short time the machine switches to LOAD and delivers
gas.
