5.1.4 Setpoint value configuration
This setting determines which analog input specifies the setpoint value, how high the
base load is, and which alternative value should be applied in the event of an error.
Value / settings Description
Setpoint input Current input This setting specifies which analog input supplies the setpoint
value for the power output.
Note:
These inputs can also be used for logic operation.
v For switching level, see Chapter 10.7 "General char-
acteristic data"
Voltage input
Binary input1 Note:
This setting is only available if power controller
r
SCR control
r
Logic (switch) is set.
In this case, the power controller is controlled in the same way
as a solid-state relay (SSR) via binary input 1 or 2:
contact: closed
r
100 % and open
r
0 %
(for control direction set ex works).
Binary input2
Via interface Means that the setpoint value for the power output is provided
via an interface.
Input in the event of
an error Current, voltage, and interface input are monitored for errors
(wire breaks or bus errors). This setting specifies which alter-
native value the power controller should use if the default set-
point value is incorrect.
Last value The last valid value is used ex works.
Voltage input or cur-
rent input Depending on which input is set for the setpoint selection, the
second free input may appear at this point.
If an error (e.g. wire break) now occurs at the current input,
which is set ex works for the default setpoint value, the power
controller uses the value at the voltage input.
Value, adjustable This means that the "Value in the event of an error" is used.
Value in the event
of an error 000.0 This value is used in the event of an error.

In the case of continuous SCR control via the analog input,
the maximum actuating variable in the master branch at the
measuring range end (e.g. 20 mA) can be varied during opera-
tion.

Continuous (power controller) is set.
The unit depends on the setting for subordinate control loop
and device type:
- U2 and U: display in V (example: 0 to 230 to 264.5 V)
- P: display in W (example: 0 to 4600 to 5290 W)
- I2 and I: display in A (example: 0 to 20 A)
- None: display in % (example: 0 to 100 %)
