Air supply system: Compressor

The compressor is driven by an electric motor. Voltage is supplied to the electric motor via a relay. The relay is activated by the EHC control unit until the specified nominal height is reached. The compressor temperature is monitored by a time model (stored in the EHC control unit). If the maximum operating time for the compressor is exceeded, further control actions are suppressed. Once the value drops below the threshold value for switching on again, adjustments can be made again.
