The parameter shows the lower limit of the line voltage measurement scale used for the voltmeter input.
3.10.2.

Upper VT voltmeter input scale limit

Address

Single- Multi-
node node

2458 410 16 bit
4506
The parameter shows the upper limit of the line voltage measurement scale used for the voltmeter input.
The default value of the upper limit depends on the controller model (see the table in paragraph "3.9.6. Upper voltmeter input scale limit").
3.10.3.

VT voltage transformer input offset

Address
Format
Single- Multi-
node node
1435
2459 411 16 bit
4507
The parameter sets the offset applied to the line voltage value read at the input of the VT voltage transformer to match the expected val-
ue. Its function is to correct a possible constant reading error. This offset applies linearly to all readings.
