DCA-70USI (50 Hz) — GENERATOR START-UP PROCEDURE (MANUAL)
Figure 48. Voltage Adjust Control Knob
Figure 49. Ammeter
(No Load)
13. The ammeter (Figure 49) will
indicate
zero amps
with no load
applied. When a load is applied, the
ammeter will indicate the amount of
current that the load is drawing from
the generator.
12. The generator's AC-voltmeter (Figure 47) will display the
generator’s output in VOLTS. If the voltage is not within
the specified tolerance, use the voltage adjustment
control knob (Figure 48) to increase or decrease the
desired voltage.

Figure 46. Frequency Meter (Hz)
11. The generator's frequency meter (Figure 46) should be
displaying the 50 cycle output frequency in HERTZ.
10.Verify that the Engine Running
status LED on the MPEC unit
(Figure 45) is ON (lit) after the
engine has been started.

Tachometer Gauge
16. The
tachometer gauge
(Figure
52) will indicate the speed of the
engine when the generator is
operating. Under normal operating
conditions this speed is
approximately 1500 RPM’s.
15. The
coolant temperature gauge
(Figure 51) will indicate the
coolant temperature. Under
normal operating conditions the
coolant temperature should be
between 165 and 215 degrees
Fahrenheit (
Green Zone
).

Temperature Gauge
14. The engine oil pressure gauge
(Figure 50) will indicate the oil
pressure (kg/ cm
2
)
of the engine.
Under normal operating conditions
the oil pressure is approximately
35~65 PSI.

Circuit Breakers (ON)
17. Place the
main
,
GFCI
, and
aux
. circuit breakers in the
ON position (Figure 53).
18. Observe the generator's ammeter
(Figure 54) and verify it reads the
anticipated amount of current with
respect to the load. The ammeter
will only display a current reading if
a load is in use.
