Voltage transformer (Add 602)
The voltage
phase conductor to phase con-
ductor (L-L)
is given as the secondary and pri-
mary voltage in the display of the UMG96S.
The transformation ratio is calculated from the
programmable
primary
and
secondary
voltages.
A transformation ratio of one is set in the fac-
tory.
300V standard version: 400V/400V (148..520V)
150V special version: 100V/100V (85..260V)
In the 300V standard version, voltage trans-
formers can be connected with the
secondary
voltage
within the range 148V to 520V.
In programming mode, the voltage transformer
setting is denoted by the symbol “
VT
”.

Programming
In programming mode, use Key 2 to page to the
voltage transformer setting. Use Key 1 to con-
firm the selection.
The first digit of the primary voltage flashes and
can be changed using Key 2. If you press Key
1, the next digit is selected and flashes.
If the whole number flashes, the decimal point
can be shifted.
If none of the digits are flashing any more, use
Key 2 to switch to display and programming of
the outputs.
