GENERATOR OUTPUTS/GAUGE READING
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 changeover switches.
Both of these switches are located on the control panel and
DO NOT effect the generator output. They are provided to
help observe how much power is being supplied, produced
at the UVWO terminals lugs.
Before taking a reading from either gauge, confi gure the
Voltage ChangeOver Board (Figure 12) which produces
the desired output voltage.
Voltage ChangeOver Board Figure 12.
240/3 Ø Position
AC Voltmeter Gauge Reading
Place the AC Voltmeter ChangeOver Switch (Figure 13)
in the WU position and observe the phase to phase voltage
reading between the W and U terminals as indicated on
the AC Voltmeter Gauge (Figure 14).

AC Ammeter Gauge Reading
Place the AC Ammeter ChangeOver Switch (Figure 16)
in the U position and observe the current reading (load
drain) on the U terminal as indicated on the AC Ammeter
Gauge (Figure 16). 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.
