Connection
Ensure that the power is disconnected during connection of the cable.
The electrical connection is made either via plug and pin or by cable.
The exact wiring scheme is shown on the sketches hereafter or at the type
plate of your sensor.
Meaning of the different connector markings
UB+
positive pole of the supply voltage
OV
negative pole of the supply voltage
S+
positive pole of the output signal
S-
negative pole of the output signal
Shielding
Cable protection enclosure-earth
The sensor can be supplied with a non stabilised DC source with the given volt-
age range. The minimum supply voltage for pressure sensors with current output
should be the minimum UB plus the minimum voltage, which is needed for the
external indicator:
