Zero position

The measured distance value is relative to the set zero point position. By default, the zero posi-
tion of the sensor coincides with the sensor front and can be set to any value between 0 and the
maximum measurement distance of the sensor. The distance value and the switching point po-
sitions are calculated relative to the zero position. The function allows tolerance measurements
for quality testing, for example.
Example 1:
Physical distance to the object to be measured: 150 mm
n
Set zero position: 0 mm (default setting)
n
Output measured value: 150 mm.
n
Example 2:
Physical distance to the object to be measured: 150 mm
n
Set zero position: 150 mm
n
Output measured value: 50 mm.

INFO
Negative values are not permitted for the zero position.

Measurement range

With the Measurement range function, the limits of the measurement range can be set so that
the active measurement range is limited to a partial range of the maximum measurement range
of the sensor. The purpose of this function is to eliminated interfering reflections (e.g. if there is
a pane of glass between the sensor and the object to be measured).
The Near limit of the measurement range must be larger than the minimum limitation of the
n
sensor (Sdc).
The Far limit of the measurement range must be smaller than the maximum limitation of the
n
sensor (Sde).
The alarm output is activated as soon as no object to be measured is located within the config-
ured measurement range or the signal quality is insufficient.
