of display C to select input element 2.
Each time
ELEMENT
is pressed the element indicator character of display C illuminates in the
order shown below. The wiring system of the circuit on the primary side of the inverter
is single-phase, two-wire, and the circuit is connected to input element 2 of the WT230.
To show the measured value of input element 2 on display C, we illuminate input
element 2.

• When input element 1 is illuminated, the line voltage across phases U and V (see
page S-5) on the secondary side of the inverter is indicated.
• When input element 3 is illuminated, the line voltage across phases W and V (see
page S-5) on the secondary side of the inverter is indicated.
• When input element
Σ
is illuminated, the average of the line voltage across phases U
and V and the voltage across phases W and V on the secondary side of the inverter is
indicated. However, this value does not have any physical meaning.
