Note: For generator sets with an ADC 2100
controller and with serial numbers below
2051416: These units used an earlier version of
the ADC 2100controller that was equipped witha
removeable power mode jumper at P7.
Operation of the remote digital gauge’s start/stop
function requires that the jumper is enabled on
the Advanced Digital Control (ADC) (generator
sets shipped from the factory already have the
jumper enabled). Refer to the wiring diagram in
the generator set operation manual if the jumper
was disconnected from terminals 1 and 2 on the
P7 connector (continuous power mode).
Note: For generator sets with an ADC 2100
controller: ADC application program version
3.32 or higher is required for complete digital
gauge operation. If your application program
version is lower than 3.32, use your SecurID to
access Kohler Power Resource Center, click on
the TechTools button, and follow the instructions
to download the files.
Note: For generator sets with a Decision-Makerr
3500 controller: Firmware version 1.14.3 or
higher is required for complete digital gauge
operation. If your firmware version is lower than
1.14.3, visit the Kohler Power Resource Center
website using the TechTools button.

Safety Precautions
WARNING
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.
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or connected equipment, 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.
Carbon monoxide symptoms. Carbon monoxide can
cause severe nausea, fainting, or death. Carbon monoxide
is a poisonous gas present in exhaust gases. Carbon
monoxide is an odorless, colorless, tasteless, nonirritating gas
that can cause death if inhaled for even a short time. Carbon
monoxide poisoning symptoms include but are not limited to
the following:
D Light-headedness, dizziness
D Physical fatigue, weakness in
joints and muscles
D Sleepiness, mental fatigue,
inability to concentrate
or speak clearly, blurred vision
D Stomachache, vomiting, nausea
If experiencing any of these symptoms and carbon monoxide
poisoning is possible, seek fresh air immediately and remain
active. Do not sit, lie down, or fall asleep. Alert others to the
possibility of carbon monoxide poisoning. Seek medical
attention if the condition of affected persons does not improve
within minutes of breathing fresh air.
Operating thegenerator set. Carbon monoxidecan cause
severe nausea, fainting, or death. Be especially careful if
operating the generator set when moored or anchored under
calm conditions because gases may accumulate. If operating
the generator set dockside, moor the craft so that the exhaust
discharges on the lee side (the side sheltered from the wind).
Always be aware of others, making sure your exhaust is
directed away from other boats and buildings.
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) Press the generator set off/reset
button to shut down the generator set. (2) Disconnect the
power to the battery charger, if equipped. (3) Remove the
battery cables, negative (--) lead first. Reconnect the negative
(--) lead last when reconnecting the battery. Follow these
precautions to prevent the starting of the generator set by the
remote start/stop switch.
WARNING
Carbon monoxide.
Can cause severe nausea,
fainting, or death.
The exhaust system must be
leakproof and routinely inspected.
Explosion.
Gasoline vapors can cause
explosion and severe injury or
death.
Before starting the generator set,
operate the blower 4 minutes and
check the engine compartment for
gasoline vapors.
Ignition-protected equipment. Explosive fuel vapors can
cause severe injury or death. Gasoline vapors can cause an
explosion. USCG Regulation 33CFR183 requires that all
electrical devices (ship-to-shore transfer switch, remote start
panel, etc.) must be ignition protected when used in a gasoline
and gaseous-fueled environment.
