6 Functions and settings
Maschinenfabrik Reinhausen 2014 66 2374092/04 EN TAPCON® 260
The device provides the following ways of changing the desired voltage val-
ue during operation:
▪
Using the control parameters menu item via the operating screen
▪ Using binary inputs
▪ Using control system protocols if a communication card is ready for op-
eration
Desired values set in kV refer to the primary voltage of the voltage trans-
former. Desired values set in V refer to the secondary voltage of the voltage
transformer. The transformer data must be entered correctly for this display.
To set the desired value, proceed as follows:
1. > Parameter > Control parameter > Press until the
desired parameter is displayed.
2. If you have already entered the transformer data, press to select
the unit you want: "V" or "kV".
3. Press to highlight the position.
ð
The desired position is highlighted and the value can be changed.
4. Press to increase the value or to reduce it.
5. Press .
ð The desired value is set.
Bandwidth
You can use this parameter to set the maximum permissible deviation in
measured voltage U
Act
. The deviation relates to the activated desired value.
The following sections describe how you determine and set the bandwidth
required.
Setting delay time T1
Use this parameter to set delay time T1. This function delays the issuing of a
tap-change command for a defined period. This prevents unnecessary tap-
change operations if the tolerance bandwidth is exited.
To set the delay time T1, proceed as follows:
1. > Parameter > Control parameter > Press until the
desired parameter is displayed.
2. Press to highlight the position.
ð The desired position is highlighted and the value can be changed.
3. Press to increase the time or to reduce it.
