The overpressure valve ÜDV1 can be omitted if it can be assured that the pressure in the interstitial space will not ex-
ceed the test pressure (e.g. through warming) and that the set pressure on the pressure reducer is lower than the test
pressure of the interstitial space.
If overpressure valves ÜDV1 from higher pressure levels are used, sufficient pressure resistance of the interstitial space
must be guaranteed.
3
The overpressure valve ÜDV2 can be omitted if the test pressure of the interstitial space is higher than the operating
pressure of the overpressure valve integrated in the pressure reducer.
4
Switches 1 to 9 are designed to select the pressure level; switch 10 is designed to select the operating mode.
