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.

Do not use copper tubing in diesel

exhaust systems. Sulfur in diesel

exhaust causes rapid deterioration

of copper tubing exhaust systems,

resulting in exhaust leakage.

9Safety Precautions and InstructionsTP-6990 8/18

Fuel System

Explosive fuel vapors.

Can cause severe injury or death.

Use extreme care when handling,

storing, and using fuels.

WARNING

The fuel system. Explosive fuel

vapors can cause severe injury or

death. Vaporized fuels are highly

explosive. Use extreme care when

handling and storing fuels. Store fuels

in a well-ventilated area away from

spark-producing equipment and out of

the reach of children. Never add fuel to

the tank while the engine is running

because spilled fuel may ignite on

contact with hot parts or from sparks.

Do not smoke or permit flames or

sparks to occur near sources of spilled

fuel or fuel vapors. Keep the fuel lines

and connections tight and in good

condition. Do not replace flexible fuel

lines with rigid lines. Use flexible

sections to avoid fuel line breakage

caused by vibration. Do not operate the

generator set in the presence of fuel

leaks, fuel accumulation, or sparks.

Repair fuel systems before resuming

generator set operation.

Explosive fuel vapors can cause

severe injury or death. Ta ke

additional precautions when using the

following fuels:

Propane (LPG)—Adequate ventilation

is mandatory. Because propane is

heavier than air, install propane gas

detectors low in a room. Inspect the

detectors per the manufacturer’s

instructions.

Natural Gas—Adequate ventilation is

mandatory. Because natural gas rises,

install natural gas detectors high in a

room. Inspect the detectors per the

manufacturer’s instructions.

Draining the fuel system. Explosive

fuel vapors can cause severe injury

or death. Spilled fuel can cause an

explosion. Use a container to catch fuel

when draining the fuel system. Wipe up

spilled fuel after draining the system.

Gas fuel leaks. Explosive fuel

vapors can cause severe injury or

death. Fuel leakage can cause an

explosion. Check the LPG vapor or

natural gas fuel system for leakage by

using a soap and water solution with

the fuel system test pressurized to

6--8 ounces per square inch

(10--14 inches water column). Do not

use a soap solution containing either

ammonia or chlorine because both

prevent bubble formation. A successful

test depends on the ability of the

solution to bubble.

LPG liquid withdrawal fuel leaks.

Explosive fuel vapors can cause

severe injury or death. Fuel leakage

can cause an explosion. Check the

LPG liquid withdrawal fuel system for

leakage by using a soap and water

solution with the fuel system test

pressurized to at least 90 psi

The automatic voltage regulator is a control device that

regulates the output voltage of the alternator by

controlling the current into the exciter field and the

reactive power (VAR) supplied by the generator set.

Input power to the AVR is derived from a single phase

permanent magnet generator (PMG exciter).

See the voltage regulator user manual (Figure 1, List of

Related Materials) for voltage regulation operation and

maintenance.

1.4.6 Customer Connections

Customer connections and accessories connect to

either the customer connection terminal or the dry

contact board located in the bottom compartment of the

control panel. See Figure 1-3

such as remote start/stop, binary inputs and

accessories such as remote emergency stop. The

customer connection terminal block also contains inputs

for breaker position and CAN communication with other

Decision-Makerr 8000 controllers.

The dry contact board contains designated relay

connections for accessories, kits, and alarms such as a

run relay, high coolant temperature alarm, overspeed

alarm, and radiator fan control connections.
