Section 2 Generator S et Operation

2.1 Prestart Checklist

To ensure continued satisfactory operation, perform the

following checks or inspections before or at each

startup, as designated, and at the intervals specified in

the service schedule. In addition, some checks require

verification after the unit starts.

Air Cleaner. Check for a clean and installed air cleaner

element to prevent unfiltered air from entering the

engine.

Air Inlets. Check for clean and unobstructed air inlets.

Battery. Check for tight battery connections. Consult

the battery manufacturer’s instructions regarding

battery care and maintenance.

Exhaust System. Check for exhaust leaks and

blockages. Check the muffler condition.

D Inspect the exhaust system components for cracks,

leaks, and corrosion. Check for tight exhaust system

connections.

D Check for corroded or broken metal parts and replace

them as needed.

D Check that the exhaust outlet is unobstructed.

Oil Level. Check the oil level before starting the

generator set and at the intervals given in Section 5,

Scheduled Maintenance. Maintain the oil level at or

near, not over, the full mark on the dipstick.

Operating Area. Check for obstructions that could

block the flow of cooling air. Keep the air intake area

clean. Do not leave rags, tools, or debris on or near the

generator set.

2.2 Exercising the Generator Set

Operate the generator set without load once each week

for 20 minutes. See Section 2.4 for information about

loaded and unloaded exercise modes. For instructions

to set the exerciser, see:

D Section 3.6 for the RDC2 controller

D Section 4.5 for the DC2 controller

2.3 Generator Set Operation

2.3.1 Local St arting and Stopping

Start: Press the RUN button to immediately start the

generator set.

Stop: Press the OFF button. The engine stops.

Run the generator set with no load for at least 2 minutes

to ensure adequate engine cooldown.

2.3.2 Automatic Starting and Stopping

An automatic transfer switch monitors the utility power

and signals the generator set to start when utility power

is lost. The ATS then transfers the load to the generator

set.

When utility power is restored, the transfer switch

transfers the load back to utility, runs the generator set

with no load to cool down the engine, and then stops the

generator set.

2.3.3 Remote Starting and Stopping

A remote switch connected to terminals 3 and 4 can be

used to start and stop the generator set. Close the

switch to start and run the generator set. Open the

switch to stop the generator set.

Run the generator set with no load for at least 2 minutes

to ensure adequate engine cooldown.

2.3.4 Engine St art Crank Cycle

The controller attempts to start the generator set three

times (three crank cycles, 15 seconds crank and

15 seconds off). If the generator set does not start in

three attempts, the system shuts down on an overcrank

fault. See Section 2.5.

Cranking 1, 2, and 3 are displayed during the crank

cycle. Pressing the OFF button during the crank cycle

stops the cranking. No other buttons are acknowledged

during the crank cycle.

2.3.5 Engine Cooldown

The engine cooldown time delay allows the engine to

run after the loads have been removed.

The engine cooldown time delay is set to 5 minutes. The

engine stops before the cooldown time delay expires if

the temperature drops below the cooled-down
