· Connect the VPPM−...C1 with a setpoint value signal. The VPPM−...C1 possesses
a differential input." The setpoint value signal 0 ... 10 V is then applied to con
tacts 3 and 4, whereby the lower potential must be connected to contact 3 and
the higher potential to contact 4. Contact 3 ( setpoint value) can be connected
to contact 7 (0 V DC).
· Apply direct current (DC) to the VPPM−...C1 (supply voltage UV = 24 V DC ± 10%).
· Pressurise the VPPM−...C1 with a supply pressure at least 1 bar higher than the
maximum desired output pressure. An output pressure p2 proportionate
thereto is then set. The following output pressure is then assigned to the set
point value signal:

7 Operation
Note
When switching off the VPPM..., make sure that first the setpoint value is set
to 0 V or 4 mA, then the supply pressure, then the setpoint value and finally the
supply voltage are switched off.
Resetting the VPPM−...C1 to the factory setting
(also if the security code cannot be found)
Note
By resetting to factory setting, the current settings are lost.
·If needed, note down these settings before resetting.
· Proceed as follows:
Reset the VPPM−...C1
1. Press and hold down the UP, DOWN and EDIT buttons.
2. Switch on the operating voltage.
3. Then release the buttons.

4. Select the parameters which you wish to reset to the factory setting with the
UP and DOWN buttons.
[Out] flashes: All output parameters are reset.
[In] flashes: All input parameters are reset.
[All] flashes: All input and output parameters as well as the security code are
reset.
5. Press the EDIT button in order to reset the selected parameters.
The VPPM−...C1 is then in the RUN mode again.
