Note: Block heater damage. The block heater will fail
if the energized heater element is not immersed
in coolant. Fill the cooling system before turning
on the block heater. Run the engine until it is
warm, and refill the radiator to purge the air from
the system before energizing the block heater.
Drive Belt(s). Check the belt condition of the water
pump and battery charging alternator belt(s).
Exhaust System. Check for exhaust leaks and
blockages. Check the silencer and piping condition and
check for tight exhaust system connections.
Inspect the exhaust system components for cracks and
corrosion (exhaust manifold, exhaust pipe, exhaust
clamps, and silencer).

2.3 Exercising the Generator Set

Operate the generator set without load every week or
every other week for 20 minutes. Perform all of the
prestart checks before starting the exercise procedure.
See Section 2.5 for instructions to set the automatic
exerciser.

2.4 Generator Set Operation

2.4.1

Local Starting 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.
2.4.2

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.
TP-6810 6/15
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 engine. The electric fans continue to run
for two minutes after the engine shuts down to evacuate
the engine compartment.
2.4.3
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.
2.4.4
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

during the crank cycle.
2.4.5
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
temperature level, or if the temperature rises above the
high limit during the cooldown cycle.

compartment.
If a transfer switch other than the Model RXT is used, an
additional engine cooldown time delay may be
programmed on the transfer switch. To allow the smart
engine cooldown on the RDC2 controller to operate
most efficiently, set the cooldown time on the transfer
switch controller to zero or the minimum time allowed.
Refer to the instructions provided with the transfer
switch for more information.
