If “ Level min. ” is higher than “ Level max. ” , the “ Level max. ” switching point is without hysteresi.
9.11.2 Limit indication depending on setting or sensor signal
Same procedure for analogue inputs “ E1 ” and “ E2 ” .
Limits Following functions can be allocated to the limit indication

col as an alarm.

In the IO setup, a separate relay can be allocated independent of these settings.
Limits 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.
