2. Pour the stipulated amount of cooling oil into the airend and replace the filler plug.
3. Turn the airend manually by means of the belt pulley to distribute the oil.
7.6 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 shut-off valve to the air network.
2. Switch on the power supply disconnecting device.
After the controller has carried out a self-test, the green
Controller voltage LED is lit continu‐
ously.
3. Press the «ON» key.
The green
Machine ON LED lights continuously.
The drive motor runs up and after a short time the machine switches to LOAD and delivers
compressed air.
➤ Watch for any faults occurring in the first hour of operation.
➤ After the first 50 operating hours, check all electrical connections and tighten where nec‐
essary.
Does the machine stop when the compressor motor rotates in the wrong direction?
➤ Switch off and lock out the power supply disconnecting device and check that no voltage
is present.
➤ Changeover phase lines L1 and L2.
➤ Acknowledge any existing alarm messages and switch the machine on again.
7.7 Setting the network setpoint pressure
The setpoint pressure (cut-out pressure) is factory set at the maximum permissible working pres‐
sure of the compressor.
Adjustment is necessary for individual operating conditions.
Do not set the machine's maximum working pressure higher than the maximum working pres‐
sure of the air main connected.
System setpoint pressure: Switching point
1. Scroll with the arrow keys until the parameter D "Setpoint pressure: switching point" is dis‐
played in line 3.
2. Press and hold «enter» for at least 3 seconds until the cursor flashes.
3. Use the arrow keys to set the desired switching point and confirm with the «Enter» key.
System setpoint pressure: Switching differential
This switching differential is factory set. Adjust this parameter if the motor starting frequency is too
high.
Precondition The machine has been running at least 5 minutes under LOAD.
