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).

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.
