GENERATOR OUTPUTS/GAUGE READING
HOW TO READ THE AC AMMETER
AND AC VOLTMETER 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 affect the generator output. They are provided to
help observe how much power is being produced at the
UVWO terminal lugs.
Before taking a reading from either gauge, configure the
Voltage Change-Over Board (Figure 21) which produces
the desired output voltage.

240/3Ø Position
AC Voltmeter Gauge Reading
Place the AC Voltmeter Change-Over Switch (Figure 22)
in the W-U position and observe the phase-to-phase voltage
reading between the W and U terminals as indicated on
the
AC Voltmeter Gauge
(Figure 23).

AC Ammeter Gauge Reading
Place the AC Ammeter Change-Over Switch (Figure 24)
in the U position and observe the current reading (load
drain) on the U terminal as indicated on the AC Ammeter
Gauge
(Figure 25). This process can be repeated for
terminals V and W.

NOTICE
The ammeter gauge will only show a reading when
the
Output Terminal Lugs
are connected to a load
and in use.
