Multiquip DCA250SSIU manual Frequency Meter

GENERATOR START-UP PROCEDURE (MANUAL)

7.The generator’s frequency meter (Figure 43) should be displaying the 60 cycle output frequency in HERTZ.

12.The coolant temperature gauge (Figure 48) will indicate the coolant temperature. Under normal operating conditions the coolant temperature should be between 167°~203°F (75°~95°C) (Green Zone).

8.The generator’s AC-voltmeter (Figure 44) will display the generator’s output in VOLTS. .

9.If the voltage is not within the specifi ed tolerance, use the voltage adjustment control knob (Figure 45) to increase or decrease the desired voltage.

10.The ammeter (Figure 46) 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.

13.The tachometer gauge (Figure 49) will indicate the speed of the engine when the generator is operating. Under normal operating conditions this speed is approximately 1800 RPM’s.

14.Place the main, GFCI, and aux. circuit breakers in the ON position (Figure 50).

11.The engine oil pressure gauge (Figure 47) will indicate the oil pressure of the engine. Under normal operating conditions the oil pressure is approximately 28 to 85 psi. (193~586 kPa).

15.Observe the generator’s ammeter (Figure 51) 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.

16.The generator will run until manually stopped or an abnormal condition occurs.
