Limit indication depending on (offset) to Setpoint

In operating modes as a controller (starting from
on the set target value (Setpoint) and measured actual value (on E1).
Only for active Setpoint of control circuit 1!
Display for operation with two control circuits: 1.Offset function, 1.Offset 1, 1.Offset 2, 1.Offset hyst.,
1.Offset Delay

In the IO setup, a separate relay can be allocated independent of these settings.
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.
"Offset 1" for alarm in case of an exceeding of the max. deviation between actual and
target.
Switch ON point: actual value = Setpoint +/- 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 = Setpoint +/- offset
Swtich OFF point: Actual value by hysteresis over the switch-on point
Offset Hysteresis
Hysteresis switch-on point: In temperature regulation + / - 10 K, otherwise sensors
10 % of measurement range
Offset Delay
Time delay until indication through relay and alarm symbol.
Setting range: 0 - 120 sec.
Factory setting: 2 sec.
