Entering the switch-off point
selects either a max contact
(switch-off point < switch-on
point) or a min contact (switch-off
point > switch-on point) and
implements a constantly required
hysteresis (see Fig. 5.4).

When the alarm threshold is
violated, the measuring
transmitter issues an alarm with
an error message and error
current (note alarm delay).
When defining the min contact,
the alarm threshold must be set
to a lower value than the
switch-off point.
