3. Press the Accept button to save the modified parameter.
TSO/CSO > and TSO/CSO <
You can set two limit values for tap selector operations / change-over selec-
tor operations:
▪ TSO/CSO >: upper limit value
▪ TSO/CSO <: lower limit value
If the Motor Current Index is greater than the upper limit value or is less than
the lower limit value, the device triggers an event message.
To set the TSO/CSO > and TSO/CSO < limit values, proceed as follows:
1. Go to Settings > Parameters > Motor Current Index > TSO/CSO > /
TSO/CSO < .
2. Enter the desired value.
3. Press the Accept button to save the modified parameter.
RSO > and RSO <
You can set two limit values for reverse tap-change operation:
▪ RSO >: upper limit value
▪ RSO <: lower limit value
If the Motor Current Index is greater than the upper limit value or is less than
the lower limit value, the device triggers an event message.
To set the RSO > and RSO < limit values, proceed as follows:
1. Go to Settings > Parameters > Motor Current Index > RSO > / RSO < .
2. Enter the desired value.
3. Press the Accept button to save the modified parameter.
K1/K2 signal assignment
You can use this parameter to set how the device is to interpret the K1 and
K2 signals:
▪ Standard: K1 = RAISE level, K2 = LOWER level
▪ Swapped: K1 = LOWER level, K2 = RAISE level
To set the K1/K2 signal assignment, proceed as follows:
1. Go to Settings > Parameters > Motor Current Index > K1/K2 signal as-
signment .
2. Select the desired option.
3. Press the Accept button to save the modified parameter.
Primary transformer current
You can use this parameter to set the primary current of the current trans-
former for measuring the motor current. The secondary current is 5 A.
