Preparing For Commissioning - Festo VPPM- C1 Serie Mode D'emploi

Note
If the Y-connecting cable type NEBV-M12G8-KD-...-M12G5 is connected to CPX
I/O modules, galvanic separation of the I/O modules is no longer guaranteed!

6 Commissioning
6.1 Fast commissioning with factory setting
The VPPM-...C1 is delivered with the following factory setting:
– Switching characteristics:
– Switching point:
The switching point is only active when a comparator is active (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 is automatically 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 seconds. The VPPM-...C1 is then
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 key.

è The VPPM-...C1 is in the RUN mode.

6.2 Preparing for commissioning

Note
• Make sure that the VPPM-...C1 is kept away from high-frequency radiation
(e.g. from radio sets, mobile telephones or other interference-emitting devi­
ces). In this way you will avoid increased tolerances of the outlet pressure
(specifications for EMC è Technical data).
• The VPPM-...C1 interprets setpoint value signals which are smaller than 1 % of
full scale as 0 V (è Fig. 29). In this case, the working pressure will be set to
the ambient pressure.
During initial start-up, the RUN mode appears. This shows the current measured
value. By briefly pressing the DOWN key, you can display the setpoint value.
The RUN mode can be accessed from other modes:

Proceed with preparation for commissioning as follows:
• Switch on the operating voltage.
è The VPPM-...-C1 is in the RUN mode.
• Check functions of the VPPM-...C1.
Observe the following when setting the control characteristics via digital inputs or
display:

Selection of the control characteristics via the digital inputs D1 and D2 takes
priority over the factory parameter sets in VPPM-...C1.
• When selecting 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 (è Fig. 27). Parameter set [Set 2] (universal control characteri­
stics) is preselected at the factory.
