General Description
With your purchase of a pressure switch, you have chosen a high-quality
product with excellent reliability. This switch features a large four-digit
display which shows the current value.
The moveable housing allows the display to be adjusted and read from
different directions. Parameters are configured using two buttons. The
process is menu-driven and self-explanatory.
Two programmable switching outputs (each independent of the other)
and an analogue output are available for connecting to electrical control-
lers. In addition, each switching output has two switching points used for
setting the activation and shut-off points as required (variable hysteresis).
The switching outputs are switched as NO or NC contacts corresponding
to the set switching points, hysteresis or window functions, and indicated
on the status display. An apparent function error will be signalled on the
digital display and can be further processed in accordance with Desina.
The electronics are protected against reverse polarity, over-voltage and
short circuits. They are also resistant to moisture and vibration.
