safety requirements on the interface are automatically met.
The OZE 3-mA is a sensor with a passive 4-20 mA two-wire interface, i.e. the
power is supplied externally, e.g. via the control unit.

Installation

If required, switch on metering unit time-delayed!
present at the input of the control unit. Design the electrical
installation such that it will not result in any uncontrolled metering
and consequential damages!
that the sensor is electrically isolated from all other consumers!
The connected control unit must be electrically isolated both from
the sensor and the power supply!
The power source must be able to provide at least 16 Vdc at a min. of
35 mA! An insufficient power supply results in an incorrect reading!
Voltage supply:
max. load:
Turn the adapter of the sensor one quarter turn anti-clockwise and pull off
(bayonet mount).
Loosen the clamping screw of the M12 screw fitting and feed through the
measuring line from the control unit.
Strip the cable ends and connect to the 2-wire connector:
1 = Plus, 2 = Minus.
