Commissioning
7.1
Overview of commissioning steps
■
Connect the voltage supply.
■
Commission the sensor using the factory settings.
■
Configure the sensor.
7.2
Positioning on drive
Different stroke lengths must be differentiated when positioning the sensor on the drive
to achieve the best possible performance.
•
Stroke > 5 mm:
The sensor head must be positioned in the center of the range of movement so
that the minimum and maximum measured position have the same value. On a
drive with a range of movement of, for example, 30 mm, the minimum position
must be -15 mm, the maximum position 15 mm.
In a device with analog output, the voltage on this drive must therefore be
between 2 V and 8 V (for measuring range at factory setting -25 mm ... 25 mm).
The optimal position of the sensor can, for example, be determined by recording
the position value or by placing an auxiliary magnet in the slot: The piston is then
moved into the end positions and the respective position of the auxiliary magnet is
marked. The center between the two marks is then the optimal position for the
sensor head (arrow on the sensor head should be at this position).

•
Stroke < 5 mm:
Mount the sensor head so that the magnet only moves in half of the measuring
range and, if possible, only positive or negative positions are output. However, the
value for the position should be no greater 8 mm.
For a sensor with analog output, the voltages should be no greater than 5 V or less
than 5 V (for measuring range at factory setting -25 mm...25 mm).

Commissioning the sensor for the first time
For optimal sensor performance, move the drive through the entire range of movement
of the drive roughly 5x. Not until teach-in is complete is the complete accuracy (minimal
linearity error, correct display of measuring range) achieved.
