Switching Mode Of The Relay Output - Burkert 8041 Manuel Utilisateur

The following diagram shows switching examples of the relay output depending on the
different possible parameter settings and the flow velocity:
Hysteresis mode
Switching time-out = 0 s
Switching time-out = 2 s
Window mode
Switching time-out = 0 s
Switching time-out = 2 s

3.6.1 Switching mode of the relay output

The switching mode of the relay output can be chosen among 2 modes, either window or
hysteresis.
- Window mode: the change of state of the relay output (OUT) occurs at any threshold
