1 Service chamber inlet
2 Service chamber outlet
In the "Cleaning" state (A), the inlet and outlet of the "inner" service chamber are used as
follows (the internal volume of the "front" service chamber does not change, and so no
pressure compensation measures are required here):
• Depending on the cleaning method, cleaning agent and purge gas are supplied via the
inlet (1).
• These media are removed via the outlet (2).
In the "Move from service position to measuring position" state (B), the pressure conditions
in the service chamber must be balanced when moving. The inlet and outlet of the service
chamber are assigned as follows:
• The air is removed via the inlet (1) (inlet is open).
• The air is supplied via the outlet (2).
