Festo VPPM-C1 Series User Manual

Note
If the Y−connecting cable type NEBV−M12G8−KD−..−M12G5 is connected to CPX
I/O modules, the I/O modules will no longer be galvanically isolated.
· Connect the cables of the VPPM−...C1 in accordance with the circuit diagram.

6 Commissioning
6.1 Fast commissioning with factory setting
The VPPM−...C1 is delivered with the following factory setting:
· Switching characteristics: Threshold value comparator
· Switching point: 40 % FS (full scale)
The switching point is only active when a comparator is selected (threshold
value or window comparator).
· Hysteresis: 0.5% FS
· Switching characteristic: NO (normally open  contact)
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
(cf. specifications on EMC in the section Technical data").
· The VPPM−...C1 interprets setpoint value signals which are smaller than 1 %
full scale as 0 V (see output pressure range table). In this case the working
pressure will be set to the ambient pressure.
During the initial start−up the RU N 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.
If a monitoring time expires (for timeout, see section Menu structure")
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
Observe the following points for setting the control characteristics via digital in
puts or display:
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,
make sure that a logic 0 signal is present at digital inputs D1 and D2.
·You can select the desired factory parameter set in the EDIT menu on the
VPPM−...C1 (see Fig.28). Parameter set Set2 (universal control characteris
tics) is preselected ex−works.
·If you wish to preselect the control characteristics via the digital inputs, activate
the following signals at digital inputs D1 and D2:
