Setting
The sensitivity and hysteresis of the level sensor are set by
trimmers “S” and “H” located under the left cover screw on
the rear side.
The basic sensitivity and hysteresis is factory adjusted and
is suitable for most applications.
The sensitivity is set by trimmer “S” located under the left
cover screw on the rear side. Clockwise turning makes the
sensitivity lower, reverse direction turning makes the sensi-
tivity higher.
If the sensed medium is at your disposal before setting into service it is useful to provide individual
setting as follows. In this way it is possible to achieve resistance against sediments.

Sensitivity
Electrical connection must be done in de-energized state! For switching supply sources,
it is necessary to check that the input is galvanically separated from the network side
and that they are fitted with a filter suppressing the conforming interference (terminals
+ and – oscillate together towards the ground potential), or the interference is removed
in another manner.
It is recommended to lead the cable separately from power distribution leads and strong sources of
EMI (pulse converters, electric motors etc.).
In case of strong ambient electromagnetic interference, paralleling of conductors with power distribu-
tion, or for the distribution to distance over 30 m, we recommend to use shielded cable.
