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 = 100.0 °C.
The value of the relevant hysteresis (
) = 0 °C.
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

°C, and switches OFF when it goes lower than
 °C
again.
The following figure shows the essentials of hysteresis,
when it’s value is higher than zero
