6.1 Programming inputs
Programming inputs La and Lb must be used in order to
make settings. A programming input at 10 to 30V
corresponds to activation (high active).
The Balluff BTL7-A-CB02-… adjusting box can be used for
this (see Accessories on page22).
Automatic deactivation!
If no signals are transmitted via the
programming inputs for approx.10min,
programming mode is automatically ended.
6.2 Calibration procedure notes
Prerequisites
– Programming inputs are connected.
– The transducer is connected to the system controller.
– Voltage or current values from the transducer can be
read (using a multimeter, the system control or the
adjusting box).

Calibration procedure
Values for null and end point
– Any desired position of the magnet can be used as the
null or end point. However, the null and end points may
not be reversed.
– The absolute null and end points must lie within the
minimum or maximum range of what can be output
(see value table).
The last set values are always saved, regardless
of whether the setting was ended using the
programming inputs or automatically after
10min have expired.
