Comment: the precondition for the following examples is
that the output is in

mode, that is, it switches ON when
the measured value ≥ L1.LL (low limit). The input signal
has an increasing characteristic, but rippled.

value
= 1000. The value of the relevant hysteresis (

) = 0.
Example:
Hysteresis > 0
A hysteresis with a value of zero means that the limit
detection has no hysteresis. The output switches ON when
the value on the display reaches or is in excess of

,
and switches OFF when it goes lower than

again.
The following figure shows the essentials of
hysteresis, when it’s value is higher than zero Figure:
Hysteresis > 0
