Generator Outputs/Gauge Reading - MQ Power DCA300SSJU4F3 Operation Manual

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, configure the
Voltage Change-Over Board (Figure 22) for the desired
output voltage.

AC Voltmeter Gauge Reading
Place the AC Voltmeter Change-Over Switch (Figure 23)
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 24).

AC Ammeter Gauge Reading
Place the AC Ammeter Change-Over Switch (Figure 25)
in the U position and observe the current reading (load
drain) on the U terminal as indicated on the AC Ammeter
Gauge (Figure 26). 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.
