3 Configuring the switching outputs
If the level is fluctuating around the set value
(e.g., ripple movement during filling), the hyster-
t
esis keeps the switching status of the outputs
stable. When the level is increasing, the output
switches when the respective switching point
HNO
(SP) is reached; if the level sinks again, the
output switches back only after the reset switch-
ing point (RP) has been reached.
HNC
The window function enables monitoring of a
defined range. If the level is between window
high (FH) and window low (FL), the output will
be active (normally open) or inactive (normally
t
closed).
The error status of the measuring device reflects
the cable break monitoring. During an error
status, the measuring device switches to the
safe state; i.e., the switching outputs become
FNC
inactive.
As far as the downstream signal evaluation is
FNO
concerned, this corresponds to a cable break.
