GENERATOR STARTUP PROCEDURE (AUTO MODE)
CAUTION
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.
DANGER
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.
NOTICE
When the generator is set in the AUTO mode, the generator will automatically start in the event of commercial power falling below a prescribed level by means of a contact closure that is generated automatically by a transfer switch.
WARNING
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
The engine speed switch must be set to the “High” position when running in the autostart mode. Failing to set the switch in the proper position can result in damage to your generator when it turns on.
NOTICE
When the MPEC control switch is placed in the AUTO position, the engine glow plugs will be warmed and the engine will start automatically.

1.Perform steps 1 through 4 in the Before Starting section as outlined in the Manual Starting Procedure.
2.Place the engine speed switch (Figure 56) in the HIGH position
Figure 56. Engine Speed Switch (High)
3.Place the MPEC Control Switch (Figure 57) in the AUTO position.
