Limit indication depending on (offset) to Setpoint
In operating modes as a controller (via
2.01
), two limit indicators can be carried out based on the set
target value (Setpoint) and measured actual value (on E1).
Offset Function
Following functions can be allocated to the limit indication

.
In the IO setup, a separate relay can be allocated independent of these settings.
Offset 1
Offset 1, Offset 2
Both values for Offset 1 and Offset 2 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 (Offset 1 and Offset 2) are initially at
“
OFF
”
.
Work can be carried out with one as well as with both limit indicators.

for alarm in case of an exceeding of the max. deviation between actual and
target.
Switch ON point: actual value = Se/- offset
Swtich OFF point: Actual value by hysteresis under the switch-on point
“
Offset 2
”
for alarm in case of an undercutting of the max. deviation between actual and
target
Switch ON point: actual value = Se/- offset
Swtich OFF point: Actual value by hysteresis over the switch-on point
Offset 2
Offset Hyst.
Offset Hysteresis

Offset Delay
Time delay until indication through relay and alarm symbol.
Setting range: 0 - 120 sec.
Factory setting: 2 sec.
