Electrical connection

Disconnect the system from power. Then connect the device according to the connection diagram.

BE-Connection:

When mounting the sensor, a galvanic connection has to be made from the electronics to the potential

of the protective wire. This is made by means of the red BE-cable.

The potential BE must be connected to the container potential! This connection should be

made over the shortest distance and routed with straight wire. (Shortening or lengthening

of the cable is possible, using a single-lead cable 0,25...1,5 mm

Please take note that the use of a DC / DC-transducer calls briefly for a higher current

than the operating current when initially switching on the equipment. Therefore the power

supply must have enough low-impedance!

Wiring of the sensor should be routed separately or screened from heavy conductor

lines, as in extreme cases inductive peak voltages can destroy the sensors despite the

integrated protective circuit. Screened cable or twisted lines are recommended, espe-

cially for longer cable runs > 5 m. Direct control of electric light bulbs is to be avoided,

because during the switch-on moment cold current is many times the rated current and

can destroy the output stage of the sensor.

Units with strong fields nearby, e. g. high power walkie-talkies, or noise sources in the

lower frequency range, e. g. long, middle or short wave transmitters should not be oper-

ated close to the sensors or additional measures have to be taken in order to eliminate

incorrect operation.
