6 Commissioning
6.1 Fast commissioning with factory setting
The VPPM-...C1 is delivered with the following factory setting:
• Switching behaviour:
• Switching point
The switching point is only active when a comparator is selected (threshold
value or window comparator).
• Hysteresis:
• Switching characteristic:
If you wish to use the factory setting but define a different switching point for Out,
proceed as follows;
Note
When the operating voltage is switched on, the VPPM-...C1 will automatically be
in the RUN mode (basic setting). If you are not sure whether the VPPM-...C1 is in
the RUN mode, hold the EDIT button down for 3 s. The VPPM-...C1 will then be in
the RUN mode. You can set switching points manually.
You can set a switching point manually as follows:
1. In order to activate the EDIT mode, press the EDIT button. [Out] flashes.
2. Press the EDIT button twice. SP flashes.
3. Edit the threshold value shown with the UP or DOWN button.
4. Hold the EDIT button pressed down for 3 s. The VPPM-...C1 will then be in the
RUN mode.

6.2 Preparing for commissioning

Note
• Make sure that the VPPM-...C1 is not subjected to high-frequency irradiation
(e.g. by radio sets, mobile telephones or other devices which emit interfer-
ence). In this way you will avoid increased tolerances in the output pressure
(EMC specifications Technical data).
• The VPPM-...C1 interprets setpoint value signals which are smaller than 1 %
full scale as 0 V ( Output pressure range table). In this case the working
pressure will be set to the ambient pressure.
During the initial start-up the RUN mode will appear. This shows the current
measured value. By briefly pressing the DOWN button you can display the setpoint
value.
The RUN mode can be accessed from other modes:
– Press the EDIT button down for 3 s.
– after expiration of a monitoring time (Timeout
Proceed with preparation for commissioning as follows:
• Switch on the operating voltage. The VPPM-...C1 will then be in the RUN mode.
• Check the functioning of the VPPM-...C1

Note
Selection of the control characteristics via digital inputs D1 and D2 takes priority
over the factory parameter sets in VPPM-...C1.
• If you wish to select the control characteristics via the factory parameters,
