Converter (Ozone prPruction)
Release of the Converter including status indication.
The converter can be turned on / off at any time when in normal operation.
The system can be operated without converter. Here gas flows through the generator, the
energy supply is switched off and thus the manual purge mode is carried out.

Dew Point Purge Mode (Option)
Release of the Purge Mode including status indication.
If the system is not switched on, the dew point can be kept at the start level for a longer
period of time. This means that a partial flow is continuously discharged via the dew point
purge valve. (start level < -56°C atm.), Purging only takes place if the inlet pressure is above
start level (> operating pressure EOZ).
