When the alarm threshold is
violated, the measuring
transmitter issues an alarm with
an error message and error
current (note alarm delay).

The switch-off point entry selects
a max contact (switch-off point
< switch-on point) or a min
contact (switch-off point
> switch-on point), thereby
implementing an always required
hysteresis function (see Fig. 5.5).
