Section 4 Troubleshooting

This section contains generator set troubleshooting,

diagnostic, and repair information.

Use the following charts as a quick troubleshooting

reference. The table groups generator set faults and

suggests likely causes and remedies. The table also

refers you to more detailed information including

sections of this manual, the generator set service

manual (S/M), the generator set installation manual

(I/M), and the engine service manual (Engine S/M) to

correct the indicated problem.

Corrective action and testing often require knowledge of

electrical and electronic circuits. To avoid additional

problems caused by incorrect repairs, have an

authorized service distributor/dealer perform service.

NOTICE

Fuse replacement.

Replace fuses with fuses of the same

ampere rating and type (for example: 3AB or 314, ceramic).

Do not substitute clear glass-type fuses for ceramic fuses.

Refer to the wiring diagram when the ampere rating is

unknown or questionable.

Maintain a record of repairs and adjustments performed

on the equipment. If the procedures in this manual do

not explain how to correct the problem, contact an

authorized distributor/dealer. Use the record to help

describe the problem and repairs or adjustments made

to the equipment.

4.1 Fault Codes

The Advanced Digital Control displays fault codes to aid

in troubleshooting. Fault codes, descriptions, and

recommended actions are listed in Figure 2-5.

Identify and correct the cause of the fault condition.

Then reset the controller after a fault shutdown. See

Section 2.6.5.

4.2 Controller Troubleshooting

Figure 4-1 contains troubleshooting, diagnostic, and

repair information for the Advanced Digital Control.

Problem

Possible Cause

Corrective Action

Controller LED display

is off

No power to the controller:

Continuous power mode jumper is disconnected

and the generator set has not run for 48 hours or

longer.

Controller display will automatically activate when a remote

start command is received or the generator set master

switch is moved to the RUN position. Connect the jumper

to maintain continuous power to the controller, if desired.

Controller fuse (F3) is blown.

Replace the fuse. If the fuse blows again, contact the

distributor/dealer.

Low or no battery voltage.

Check connections.

Check generator set battery.

Generator set master switch is in the OFF/RESET

position.

Move generator set master switch to the AUTO or RUN

position.

Generator set master switch in AUTO but no start

command has been received since last controller

reset.

No action required. Controller display will activate when a

remote start command is received or the generator set

master switch is moved to the RUN position. Use the

remote switch to start generator set and activate the

controller display, if desired.
