Diesel Generator Operation Manual Control System Part 6
Alternator Data Submenus
If the Alternator Data button in Menu A is pressed, the Alternator Data submenus will appear (Figure 6-1).
6.1 Voltage L–L and L–N
Indicates voltage Line–to–Line, and Line–to–Neutral. Note that the Line–to–Neutral column will not be displayed for a 3-phase/3-wire system. Accuracy 1%.
The voltages Line–to–Line (L1, L2 and L3) are measured between L1 to L2, L2 to L3 and L3 to L1, respectively.

All phases. Accuracy 1%.
Generator set output frequency.
6.4 AVR Duty Cycle
Displays voltage regulator (drive) level in percentage of maximum.
6.5 kW, kVA and PF
Displays generator set kW and kVA output (average and individual phase, and direction of flow) and power factor with leading/lagging indication. Accuracy 5%.
Note:The PF reading will contain an asterisk if the power factor is leading (e.g., *.30).
