The output is switched analogously upon entry into and upon exit from the upper track limit.
The output is reset when the actual value reaches the ”upper track limit+hysteresis”.
(without Fig.)
b) Setting of an output
Fig. 7-9 shows switching of an output upon exit from and upon entry into the upper track
limit.
The output is reset when the upper track limit is exceeded, and the specified hysteresis value
goes into force for this limit. The direction is reversed within the hysteresis range. The output
is set when the actual value reaches the ”upper track limit - hysteresis”.

The output is switched analogously upon exit from and upon entry into the lower track limit.
The output is set when the actual value reaches the ”lower track limit+hysteresis”.
(without Fig.)
If an output was allocated during the configuring phase to several overlapping tracks, a hysteresis
is taken into account only on the lower track limit of the lowest and on the upper track limit of
the highest track.
