If the alarm threshold is undershot/
overshot, this triggers an alarm with the
error message and error current at the
transmitter (note alarm delay in field F3).
If defined as a Min contact, the alarm
threshold must be < switch-off point.
If two factory settings are displayed the
one on the left side stands for CUS41 the
one on the right side stands for CUS31.

Entering a switch-off point selects either a
Max contact (switch-off point < switch-on
point) or a Min contact (switch-off point >
switch-on point), thereby implementing a
hysteresis that is constantly required (see
"Illustration of the alarm and limit
functions" figure).
