DCA-70USI (50 Hz) — GAUGE READING
How to Read the Output Terminal 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
Output terminals lugs
.
Before taking a reading off either gauge, set the
Voltage
Selector Switch
(Figure 17) to the position which produces
the required voltage (For example, for 3Ø 200V,
choose the center 3Ø 240/
139V position on the volt-
age selector switch.)

(Volt reading on W-U Lug)
For 3Ø 200V/1Ø,115V, place
the Voltage Selector Switch
in the 3 Phase 240/139
position.

The
ammeter
gauge will only
show a reading when the
Output Terminal Lugs
are
connected to a load and in use.
NOTE
Reading Voltage
To determine the voltage between two terminal lugs, set the
AC Voltmeter Change-Over
Switch
to the appropriate
setting (Figure 18) to activate the
AC Voltmeter Gauge
(Figure 19) 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
.
NOTE
Reading Amperage
To determine the amperage at a terminal lug, set the
AC Ammeter Change-Over
Switch
to the appropriate
setting (Figure 20) to activate the
AC Ammeter Gauge
(Figure 21) 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.
