Calibration control
4.2.1 Calibration Control at Analog Output
By applying voltage of +5 V to +28 V the calibration control will switch on.
Voltage below 2,8 V will switch off the calibration control.
4.2.2 Calibration Control at RS485
The calibration control switch on is carried out by a command.
For this, ask for Protocol (document no. 090110).
4.3
Cable
Only use a shielded cable with preferably small capacity. We recommend measuring cables from our product range.
They have been tested in combination with our sensors and meet the metrological requirements.
4.4
Shielding Connection
In combination with the sensor and the external electronics, the shield forms a Faraday Cage. By this, electro-
magnetic disturbances do not have any influence on the measurement signal.
4.5
Running of Measuring Cables
Do not run measuring cables together with control or heavy-current cables. Always assure that a large
distance is
kept to engines, transformers and contactors, because their stray fields can lead to interferences of the measuring
signals.
If troubles occur through the measuring cable, we recommend to run the cable in a grounded steel conduit.
4.6
Angle (Option)
At angle or speed measurement, the pulses / revolutions are
acquired. By a second transmitter trace, displaced by 90° and
flank evaluation, the pulses / revolutions can be quadrupled.
The trace, displaced by 90°, can also be used for the rotational
direction detection.
See corresponding data sheet for the output levels.
