If the level is uctuating around the
target value (e.g. ripple movement
during lling), the hysteresis keeps the
switching status of the outputs stable.
When the level is increasing, the
output switches when the respective
switching point (SP) is reached; if the
level sinks again, the output switches
back only after the reset switching
point (RP) has been reached.

The window function enables moni-
toring of a dened range. If the level
is between window high (FH) and
window low (FL), the output will be
active (normally open) and/or inactive
(normally closed).
The error status of the measuring
device reects the cable break
monitoring. During an error status,
the measuring device switches to
a safe state; i.e. the switching outputs
become inactive.
As far as the downstream signal
evaluation is concerned, this
corresponds to a cable break.
