In the IO setup, a separate relay can be allocated independent of these settings.
Both values for E1 ("E1 min" and "E1 max") can be set independent of each other and
act on a relay together if correspondingly programmed. If a function is activated or if a
relay is allocated, both settings ("min" and "max") are initially at "OFF".
Work can be carried out with one as well as with both limit indicators.
The same setting applies to "E2 Min." and "E2 Max.", described below for "E1".
Undercutting the signal ("E1 Min").
If the signal undercuts the set value "E1 min", this is reported until the set value (plus
adjustable hysteresis) has been exceeded once again.
Exceeding the signal ("E1 max").
If the signal exceeds the set value "E1 max", this is reported until the set value (minus
hysteresis) has been undercut once again.
E1 Hysteresis
Hysteresis adjustment in the unit of measure of the programmed input signal.
