4.3 Operating modes and control modes
4.3.1 Machine operating modes
There are two operating modes:
■ LOAD
The machine delivers compressed air.
The drive motor runs under full load.
■ READY:
No air is compressed. The check valve to be installed by the user prevents already com‐
pressed air flowing back into the compressor. The compressor block is vented.
The drive motor is stopped.
4.3.2 External control unit
An external control unit is required to activate the drive motor, the pressure switch, the solenoid
valve, and the oil level monitoring (Option C5). This enables an unloaded starting of the machine.
The control unit is not provided with the machine and is to be supplied by the user.
WARNING
Controller voltage!
➤ Incorrect control voltage can lead to irreparable damage to the electrical componentes.
Use the START CONTROL controller by KAESER.
The following points have to be observed:
■ Install the control unit to EN 60204 specifications.
■ Select the components to suit the motor power.
■ Connect the solenoid valve such that it first closes when the drive motor has run up to speed.
Further information The operating manual of the START CONTROL control unit provides detailed information about
the function and design of the control unit. This manual is a component of the shipment.
