How to Read the AC Ammeter and AC Voltage Gauges.
The AC ammeter and AC voltmeter gauges are controlled
by the AC ammeter and AC voltmeter change-over switches.
Both of these switches are located on the control panel and
DO NOT effect the generator output. They are provided to
help observe the phase to phase voltage and the current
flowing to the load at the UVWO output terminals lugs.
Observe that the voltage change-over board (Figure 17) has
been configured for 3Ø, 240V operation.

AC Voltmeter Gauge Reading
Place the (Figure 18)
in the W-U position and observe the phase to phase voltage
reading between the W and U terminals as indicated on the
(Figure 19).
AC Ammeter Gauge Reading
Place the (Figure 20)
to the U position and observe the current reading (load drain)
on the U terminal as indicated on the
(Figure 21). This process can be repeated for terminals V
and W.
