The valves are assigned in "Set up 2 > Topcal > Config. Topcal".
Activate the sealing water in "Set up 2 > Topcal > Activate Topcal".
What is sealing water?
In processes where the medium is fibrous or tends to stick, assemblies with a ball valve for shutting
off the medium are used e.g. Cleanfit P CPA473 or CPA474. To keep the rinse chamber free of
medium, the sealing water valve opens automatically before the assembly moves out of the process.
The counterpressure in the rinse chamber caused by the sealing water prevents the ingress of
medium into the chamber. The sealing water pressure must then be greater than the pressure of the
medium. The time the sealing water runs before and after moving the assembly can be set
individually.
