1. Unlock the rotary knob (only DPA-63-10-… and DPA-100-10-…).
2. Turn the rotary knob clockwise as far as stop (delivery condition).
3. Apply inlet pressure to port P1.
Note
Do not exceed the maximum permitted pressure.
Use to check the pressure gauges:
–
inlet pressure at port P1:
max. 8 bar
–
differential pressure between ports P1 and P2:
min. 2 bar
4. Turn the rotary knob clockwise until the desired outlet pressure is reached.

The outlet pressure setting is less than
the inlet pressure.
The pressure regulator on the DPA relieves pressure until
pressure levels are in balance. The CRVZS is emptied.
The outlet pressure setting is at least
2 bar greater than the inlet pressure.
Normal operating status. The outlet pressure is reached.
The DPA also switches at low air consumption.
