You can find a short introduction into parameter setting and routing of the binary inputs for the tap position in
chapter 6.8.2 Application and Setting Notes.
Besides the tap-position display via
BCD with prefix , the SIPROTEC 5 device offers the option to code the
tap position as follows:
•
Binary
•
1-of-n
•
BCD
•
Table
•
Gray Code
•
IEC 61850 GOOSE indication (Type BSC)
Optionally, you can also use an mA signal or a resistance-coded tap-position display. An ANAI module must be
installed for the analog integration of the tap-position signal.
Checking the Tap Position
The active binary input is marked with a cross in the device menu under the entry Binary IO. Siemens recom-
mends driving through all positions of the tap changer completely, if possible, thereby testing the correct tap-
changer position indication once the parameterization of the tap position detection is finished and the tap-
position display is activated.
You can carry out the tap-position check from the on-site operation panel or from the DIGSI Online-Editor. If
you are using the DIGSI Online-Editor, set the switching authority of the device to Remote and the operating
mode of the voltage controller to Manual.
