• Connect the VPPM-...C1 with a setpoint value signal. The VPPM-...C1 possesses
a so-called “differential input.” The setpoint value signal 0 ... 10 V is then ap-
plied to contacts 3 and 4, where the lower potential must be connected to con-
tact 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 %).
• Pressurize the VPPM-...C1 with an input 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:

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 settings, the current settings are lost.
• If required, make a note of 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.

Service and maintenance
Cleaning:
• Switch off the following sources of energy before cleaning the exterior of the
device:
– Operating voltage
– Compressed air
• If the VPPM-...C1 is dirty, clean the exterior with a soft cloth.
The permitted cleaning agents are mild soapy water (max. + 50 °C ) or all non-
abrasive media.
