1. Supply the MPPES-... with direct current
(supply voltage U
= DC 24 V).
v
2. Pressurise the MPPES-... with an input pressure higher than the
maximum desired output pressure.
3. Supply current to the MPPES-... with a setpoint value signal
corresponding to the valve type (current/voltage variant).
A proportional output pressure P
To the setpoint value signal range DC 0 ... 10 V or 4 ... 20
mA are assigned the following pressure ranges, depending
on the design (è Tab. 3):

For visual inspection of the control process at the MPPES-...:
Wire the MPPES-... with the following measuring device according
to Fig. 13/Fig. 14:
Use for the
– voltage variant a voltage measuring device
and for the
– current variant a current measuring device (ammeter).
The actual electrical value can be tracked on the display of the meas
uring device. This changes proportional to the pressure curve at port
2.
