Automatic CO2 purge of the dryer, HMI TCC-Control

Description

During the filling process, the dryer cartridge is enriched with the CO2 flowing through it. When the flow stops after the compressor shuts down, the cartridge releases the CO2 again, and the entire dryer cartridge housing is filled with CO2.
To ensure that this CO2 does not enter the breathing apparatus, the CO2 in the dryer housing is flushed out for about 30 seconds when the compressor starts and only then is the air passed on to the filling device for filling.
