Displays generator voltage as follows:
3-phase system: LINE TO LINE VOLTAGE--Phases C-A
1-phase system: LINE TO NEUTRAL VOLTAGE--Phases B-N
8.2.4.4. GENERATOR PHASE/NEUTRAL VOLTAGE DISPLAY (LINE
TO NEUTRAL)
The generator phase/neutral display allows the operator to view the
generator line to neutral voltage for all 3 phases of the system. Note:
The generators neutral must be connected to MEC 2 terminal TB1-VN
and the “neutral connected” prompt in the main program menu must be
selected as “Yes”.
