6.3 Supply voltage

The transducer must be operated with a separated extra‐low voltage (supply

voltage 9…36 VDC).

7 Functional testing

You can check the functionality of the rotor and the stator from the LEDs on

the evaluation unit.

• It is not allowed to extend or reduce the length of the connection

cable between rotor and evaluation unit!!!

• Don’t lay cable parallel to high voltage and control cable. If this is not

avoidable, please let a minimum gap of 50cm and lay the cable inside a

steel tube.

• Avoid transformer, motor, gate, thyristor circuits and similarly leakage

fields.

Important

• Check the calibration signal specified on the type label or test protocol.

• To obtain stable conditions, the measurement should be started or the

calibration signal should be activated only once the transducer has been

warming up for 15 minutes.
