Kohler Industrial Generator Set - 3.10.4 Charge Battery

TP-6694 7/1874 Section 3 Scheduled Maintenance
3.10.4 Charge Battery
Use a battery charger to maintain a fully charged battery
when the generator set is used in a standby application.
The engine battery-charging alternator charges the
battery while the generator set is running.

C F
Example No. 1
Temperature below 26.7
C(80F)
Hydrometer Reading 1.250
Acid Temperature --6.7
C(20F)
Subtract .024 Specific Gravity
Corrected Specific Gravity is 1.226
1.250 -- .024 = 1.226
Example No. 2
Temperature above 26.7
C(80F)
Hydrometer Reading 1.235
Acid Temperature 37.8
C (100F)
Add .008 Specific Gravity
Corrected Specific Gravity is
1.243
1.235 + .008 = 1.243
The t emperature correction amounts
to about .004 (4 points) of specific
gravity for each 5.5C(10F) change
in temperature.

Note: If the generator set is in a temporary prime power
application in which the generator set has periods
of inactivity, the controller circuitry may drain the
battery. If there is no power source for a battery
charger, place the controller in the prime power
mode, if equipped, or disconnect the battery from
the generator set.
3.11 Storage Procedure
Perform the following storage procedure before taking a
generator set out of service for three months or longer.
Follow the engine manufacturer’s r ecommendations, if
available, for fuel system and internal engine
component storage.
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (--) lead first
when disconnecting the battery.
Reconnect the negative (--) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or equipment connected to the set, disable the
generator set as follows: (1) Move the generator set master
switch to the OFF position. (2) Disconnect the power to the
battery charger. (3) Remove the battery cables, negative (--)
lead first. Reconnect the negative (--) lead last when
reconnecting the battery. Follow these precautions to prevent
starting of the generator set by an automatic transfer switch,
remote start/stop switch, or engine start command from a
remote computer.
Hot engine and exhaust system.
Can cause severe injury or death.
Do not work on the generator set until
it cools.
WARNING
Servicing the exhaust system. Hot parts can cause
severe injury or death. Do not touch hot engine parts. The
engine and exhaust system components become extremely
hot during operation.
Hazardous voltage. Moving parts.
Will cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
areinplace.
