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
OFF

col as an alarm.

Message

sage on the actual value display and no message via alarm relay.

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.

Information
Always adjust the value for the maximum input signal higher than the value for the minimum input
signal!
