DCA-70USI (50 Hz) — GENERATOR START-UP PROCEDURE (MANUAL)

10.Verify that the Engine Running status LED on the MPEC unit (Figure 45) is ON (lit) after the engine has been started.

Running LED (ON)

11.The generator's frequency meter (Figure 46) should be displaying the 50 cycle output frequency in HERTZ.

Figure 46. Frequency Meter (Hz)

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.

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.

(No Load)

14.The engine oil pressure gauge (Figure 50) will indicate the oil pressure (kg/ cm2) of the engine. Under normal operating conditions the oil pressure is approximately 35~65 PSI.

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).

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.

17.Place the main, GFCI, and aux. circuit breakers in the ON position (Figure 53).

Circuit Breakers (ON)

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.
