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 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 Voltage
Selector Switch (Figure 14) to the position which produces
the required voltage (For example, for 3Ø 240V, choose
the center 3Ø 240/139V position on the voltage selector
switch).

AC Voltmeter Gauge Reading
Place the AC Voltmeter Change-Over Switch (Figure 15)
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 16)
NOTICE
For 3Ø 208V/1Ø,120V, place the Voltage Selector
Switch in the 3 Phase 240/139 position.

AC Ammeter Gauge Reading
Place the AC Ammeter Change-Over Switch (Figure 17)
in the U position and observe the current reading (load
drain) on the U terminal as indicated on the AC Ammeter
Gauge (Figure 18). 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.
