flashes. To confirm, press the EDIT key.
[Lock] flashes, display [OFF] or display of security code.
5. Set the desired security code, maximum 4-figure, with the UP or DOWN key (OFF = no protec­
tion). To confirm, press the EDIT key.
Tip: Keep the security code where it can be found.
If the security code is forgotten è Section 7.
6. To confirm, press the EDIT key.

• 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, 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).
• Supply the VPPM-...C1 with direct current (supply voltage UV = 24 V DC ±10 %).
• Pressurize the VPPM-...C1 with a supply pressure at least 1 bar higher than the
maximum desired outlet pressure. An outlet pressure p2 proportionate to it is
then set. The following outlet pressure is then assigned to the setpoint value
signal:

– Outlet pressure: 0 V or 4 mA generates an outlet pressure of 0 bar

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, after that the setpoint value, and finally
the supply voltage is switched off.
Reset VPPM-...C1 to factory setting
(also if the security code cannot be found)
Note
By resetting to factory settings, the current settings are lost.
• Carry out the following steps:
Resetting the VPPM-...C1
1. Press and hold down the UP, DOWN and EDIT keys.
2. Switch on the operating voltage.
3. Release the keys again.
