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 change-over
switches.
Both of these switches are located on the generator 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, set the 3-position
voltage selector wheel switch (Figure 13) to the position
which produces the desired voltage. For example, 3Ø, 240V,
choose the center position on the voltage selector wheel
switch.

Wheel Switch .
AC Voltmeter Gauge Reading
Place the AC Voltmeter Change-Over Switch (See Figure
14) 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 15).

AC Ammeter Gauge Reading
Place the AC Ammeter Change-Over 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 17). 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.
