5.1.4 Set point value configuration
Here you can determine the analog input that specifies the set point value, how high
the base load should be and which alternative value is to be used in the event of a
fault.
Value/settings Description
Default set point
value Current input This setting specifies which analog input is to supply the set
point value for the power output.
Voltage input
Binary input 1 Note: This setting is only available when the controller

control
➔
Logic (switch) is set.
In this case, the power controller is controlled like a solid state
relay (SSR) via binary input 1 or 2.

(with factory-set control direction).
Binary input 2
Via interface This means that the set point value for the power output is
provided via an interface.
Default value in the
event of a fault Last value The current, voltage and interface inputs are monitored for
faults/errors (line/wire breaks or bus errors). This setting is
used for specifying which alternative value is to be used by the
power controller if the default set point value is faulty.
The factory setting specifies use of the last valid value.
Voltage input or cur-
rent input
Depending upon which input is set for the default set point
value, the second (still free) input appears at this point.
If a fault (e.g. line/wire break) occurs at the current input that is
factory set for the default set point value, the power controller
then uses the value at the voltage input.
Value, adjustable This means that the " Value in the event of a fault" is used.
Value in the event
of a fault 000.0 This value is used in the event of a fault.
