Kohler Industrial Generator Set - Cold Weather Operation and Controller Starting

TP-6694 7/1836 Section 2 Operation
2.3 Operation in Cold Weather
Climates
Cold weather operation is generally considered ambient
temperatures below freezing 0C(32F). The following
items are recommended for cold weather starting and/or
operation when the unit is located in an enclosure or
unheated structure. Have a licensed electrician install
120 VAC, 15 amp outlets as needed if not already in the
immediate area.
Refer to the engine operation manual regarding engine
oil viscosity, fuel composition, and coolant mixture
recommendations.
D The engine block heater is generally recommended
for most units when operated below 0C(32F) and
required as part of NFPA 110. Refer to the respective
spec sheet for temperature recommendations in
available options.
D A battery heater is generally recommended for most
units when operated below 0C(32F). Refer to the
respective spec sheet for model availability.
D An alternator strip heater is available for most
generator sets providing a heat source to prevent
moisture and frost buildup.
D The crankcase ventilation (CCV) heater kit
provides a controlled heating source to the crankcase
ventilation system preventing freezing water buildup
during cold weather. The thermostat turns on at 4_C
(40_F) and turns off at 16_C(60_F). Refer to
Section 3, Scheduled Maintenance for more
information. (Applies to 125/150 kW, 8.1 L GM- and
8.8 L PSI- powered generator set models only.)
D Heater tape is recommended when the generator set
is equipped with a closed crankcase ventilation
system and operated at or below 50% of rated load.
Wrap the UL/CSA compliant heater tape around the
crankcase canister/breather system hose that runs
from the crankcase to the air intake and use cable ties
as needed to secure the heater tape. If the heater
tape is within 152 mm (6 in.) of the exhaust system,
use thermal insulation material to protect the heater
tape.
40--60REOZK Models only. When the ambient
temperature drops below --15_C(5_F) a turbocharger
pre-lube sequence begins when the crank cycle is
initiated. During the first 10 seconds of cranking, the fuel
system is disabled to ensure engine oil is present at the
turbocharger. This is necessary for the longevity of the
turbocharger on the KDI 3404TM engine. The fuel
system is then enabled for the next 5 seconds of cyclic
cranking and the engine will start as normal.
2.4 Controller Operation
The controller operation includes several types of
starting and stopping functions as detailed in the
following paragraphs. The controller master control
switch buttons, lamps, and alarm horn functions are
summarizedinFigure2-1.
