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 calibration box BTL7-A-CB02-… can be used
for this (see Accessories on page 20).
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 BTL connected to the system controller.
– Voltage or current values from the BTL can be read
(using a multimeter, the system control or the
calibration box).

Values for null and end point
– Any desired position of the float 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.
