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 16) 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

Ø Position

ac voltmeter gauge reading

Place the

AC Voltmeter Change-Over Switch (Figure 17)

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 18).

ac ammeter gauge Reading

Place the

AC Ammeter Change-Over Switch (Figure 19)

in the U position and observe the current reading (load

drain) on the U terminal as indicated on the

AC Ammeter

Gauge (Figure 20). 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.
