GENERATOR START-UP PROCEDURE (MANUAL)

BEFORE STARTING

CAUTION

The engine’s exhaust contains harmful emissions.

ALWAYS have adequate ventilation when operating. Direct exhaust away from nearby personnel.

WARNING

NEVER manually start the engine with the main, GFCI or auxiliary circuit breakers in the ON (closed) position.

1.Place the main,G.F.C.I.,and aux. circuit breakers (Figure 35) in the OFF position prior to starting the engine.

Figure 35. Main, Aux. and GFCI

Circuit Breakers (OFF)

2.Make sure the voltage change-over board has been confi gured for the desired output voltage.

3.Connect the load to the receptacles or the output terminal lugs as shown in Figure 10. These load connection points can be found on the output terminal panel and the output terminal panel’s hard wire hookup panel.

4.Tighten terminal nuts securely to prevent load wires from slipping out.

5.Close all engine enclosure doors (Figure 36).

STARTING (MANUAL)

1.Place the battery ON/OFF switch (Figure 37) in the ON position.

Figure 37. Battery ON/OFF Switch (ON)

2.Place the engine speed switch (Figure 38) in the LOW (down) position.

Figure 38. Engine Speed Switch (Low)

3.Place the MPEC control switch in the MANUAL position to start the engine (Figure 39).

Figure 39. MPEC Control Switch

(Manual Position)

4.Depending on the temperature of the coolant (cold weather conditions), the pre-heat lamp (Figure 40) will light (ON) and remain on until the pre-heating cycle has been completed. After completion of the pre-heating cycle, the light will go OFF and the engine will start up automatically.

5.Once the engine starts, let the engine run for 1-2 minutes. Listen for any abnormal noises. If any abnormalities exist, shut down the engine and correct the problem. If the engine is running smoothly, place the engine speed switch (Figure 41) in the HIGH (up) position.

Figure 41. Engine Speed Switch (High)

6.Verify that the engine running status LED on the MPEC unit (Figure 42) is ON (lit) after the engine has been started.
