Multiquip DCA-45US1 DCA-45USI Gauge Reading, How to Read the OutputTerminal Gauges

How to Read the OutputTerminal Gauges.

The gauges and selector switches on the control panel DO NOT effect the generator output. They are provided to help observe how much power is being supplied at the Out- put Terminal Lugs.

Before taking a reading off 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 posi-

tion on the voltage selector switch.)

DCA-45USI — GAUGE READING

Reading Amperage

To determine the amperage at a terminal lug, set the AC Ammeter Change-Over Switch to the appropriate setting (Figure 19) to activate the AC Ammeter Gauge (Figure 20) and read the available amperage at the terminal lug.

For example, to measure the amperage at the U terminal lug, set the AC Ammeter Change-Over Switch to U and read the AC Ammeter Gauge.

To determine the voltage between two terminal lugs, set the AC Voltmeter Change-Over Switch to the appropriate setting (Figure 17) to activate the AC Voltmeter Gauge (Figure 18) and read the available voltage between the two lugs.

For example, to measure the voltage between the W and U terminal lugs, set the AC Voltmeter Change-Over Switch to W-U and read the AC Voltmeter Gauge.
