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)

Figure 14. Voltage Selector Switch

240/139V 3Ø Position

NOTICE

For 3Ø 208V/1Ø,120V, place the Voltage Selector Switch in the 3 Phase 240/139 position.

AC Voltmeter Gauge Reading

Place the ACVoltmeter 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)

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.
