DCA-125USJ — GENERATOR START-UP PROCEDURE (AUTO MODE)

16.Observe the generator's ammeter (Figure 53) 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.

Figure 53. Ammeter (Load)

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

WARNING - AUTO MODE MAINTENANCE

When running the generator in the AUTO mode, remember the generator can start up at any time without warning. NEVER attempt to perform any maintenance when the generator is in the auto mode.

CAUTION - ENGINE SPEED SWITCH

The Engine Speed Switch must be set to the “High” position when running in the Auto-Startmode. Failing to set the switch in the proper position can result in damage to your generator when it turns on.

DANGER - ELECTRICAL SYSTEM HAZARDS

Before connecting this generator to any building’s electrical system, a licensed electrician must install an isolation (transfer) switch. Serious damage to the building’s electrical system may occur without this transfer switch.

CAUTION - BACKUP GENERATOR USE

When connecting the generator to a isolation (transfer) switch, ALWAYS have power applied to the generator's internal battery charger. This will ensure that the engine will not fail due to a dead battery.

is placed in the AUTO position,

NOTEthe engine glow plugs will be warmed and the engine will start automatically.

When starting generator in AUTO mode use the "Manual Start-up" procedure except where noted (see below).

1.Perform steps 1 through 5 in the Before Starting section as outlined in the Manual Starting Procedure.

2.Place the MPEC Control Switch (Figure 54) in the AUTO position

When the generator is set in the AUTO mode, the generator will

NOTE automically start in the event of comercial power falling below a prescribed level by means of a contact closure that is generated automatically by a transfer switch.

3.Continue operating the generator as outlined in the Manual Start-upprocedure (start at step 9).
