9.4.2 Tap position capture method
The current tap position of the on-load tap-changer is transmitted from the
motor-drive unit to the device. You can use this parameter to select the type
of tap position capture.
In order to ensure proper function of the tap position capture, make sure
that the inputs of the corresponding tap position capture method are acti-
vated and correctly wired.
1. Go to Settings > Parameters > On-load tap-changer > Tap position
monitoring > Tap position capture method .
2. Select the desired tap position method.
3. Press the Accept button to save the modified parameter.
The tap position is transmitted in one of the following ways:
9.4.2.1 Digital tap position capture
The tap position can be transmitted as a digital signal from the motor-drive
unit to the device. The following variants are available:
▪ BCD
▪ Dual code
▪ Gray code
▪ N/O contact series
9.4.2.2 Analog tap position capture
The tap position can be transmitted as an analog signal from the motor-drive
unit to the device. The following variants are available:
9.4.2.2.1 Injected current (0/4…20 mA)
For the analog tap position capture, you must set which tap positions corre-
spond to the minimum analog signal and maximum analog signal.
Pos. at max. analog signal
You can use this parameter to set the tap position of the on-load tap-
changer corresponding to the maximum analog signal (e.g. 20 mA for
4...20 mA signal).
1. Go to Settings > Analog tap position capture > Pos. at max. analog
signal .
2. Set the tap position.
3. Press the Accept button to save the modified parameter.
