Commissioning instructions for the proportional pressure regulator
Note
Place the proportional pressure regulator as near as
possible to the consuming device. This will lead to better
control accuracy and shorter response times.
Make sure there is sufficient space for the connecting
elements. In this way you will prevent the connecting
cable from being bent.
Long signal cables reduce the immunity to interference.
Make sure that the signal cables are not longer than
10m.
Make sure that the proportional pressure regulator is
not subjected to high−frequency irradiation (e.g. by radio
sets, mobile telephones or other devices which cause
interference). In this way you will avoid increased toler
ances in the output pressure (compare specifications on
EMC in appendix A).
The proportional pressure regulator interprets nominal
values which are smaller than 1 % full scale as zero point
switching off, i.e. the valve is force−ventilated and there
fore assumes a defined position.
Pressurise the proportional pressure regulator with an
input pressure at least 1 bar higher than the maximum
required output pressure. A proportional output pres
sure P2 sets itself as the nominal value. Tab.4/9 shows
the output pressure which is assigned to the end ranges
(1 % FS or 100 % FS) of the nominal value.
When switching off the proportional pressure regulator,
make sure that first the supply pressure, then the supply
voltage is switched off.
