Parameter: Winding selection
•
Default setting
(_:16351:161) Winding selection
=
Winding 1
With the
Winding selection
parameter, you specify whether the controller controls the voltage of
Winding 1
or
Winding 2
.
You may select the winding to be controlled using the
Winding selection
parameter or the
Manual
winding selection
controllable. The function value
Active winding
shows the winding selection.
Controlling
Parameter: Check switching authority
•
Default setting
(_:107) Check switching authority
=
yes
With the
Check switching authority
parameter, you specify whether the switching authority (On-site,
Remote) is checked during an adjusting command.
Parameter: Control model
•
Default setting
(_:109) Control model
=
SBO w. enh. security
This parameter
Control model
specifies the control model according to IEC 61850-7-2 that corresponds to
the behavior of the data (SBO – Select Before Operate).
You can select one of the following settings:
•
direct w. normal secur.
•
SBO w. normal secur.
•
direct w. enh. security
•
SBO w. enh. security
Parameter: SBO time-out
•
Default setting
(_:110) SBO time-out
=
30.00 s
This parameter specifies the time for detecting the time-out of the SBO command. The range of values
extends from 0.01 s to 1800.00 s. This is the time that can elapse between command acceptance and
command execution (command model as per IEC 61850-7-2).
Parameter: Feedback monitoring time
•
Default setting
(_:111) Feedback monitoring time
=
10.00 s
Reaching a new tap position after the adjusting command is monitored via the feedback-monitoring time. If a
new tap position is not reached, the command is canceled after this time.
Voltage Controller
Parameter: Number of target voltage
•
Default setting
(_:14011:156) Number of target voltage
=
1
With this parameter, you specify the number of available
target voltages
(
1
to
4
). You can select a target
voltage from the available ones using the function key, communication, or binary input.

i
NOTE
Keep in mind that the parameter
Number of target voltage
cannot be influenced by way of the
settings group switching.
You can specify the
target voltages
(
1
to
4
) in primary, secondary, or in percent.
For the activation of the target voltage 1 to 4 via a binary input, you need a CFC chart.
Parameter: Target voltage 1
•
Default setting
(_:14011:112) Target voltage 1
=
110.000 V
With the
Target voltage 1
parameter, you specify the voltage that the voltage controller is supposed to
reach.
