Section 4 General Troubleshooting
This section contains generator set troubleshooting and
diagnostic information.
Use the following charts to diagnose and correct
common problems. First check for simple causes such
as a dead engine starting battery or loose connections.
The generator set may be connected to a customer-
supplied remote control system.
Disconnect the
generator system from the remote control system at
plug P6 and use the generator set master switch to
operate the generator set. If the problem persists after
P6 is disconnected, use the troubleshooting procedures
in this manual to diagnose the problem. If the generator
set operates normally when P6 is disconnected, the
remote controller may have sent a remote stop
command or there may be a problem with the remote
control system. Refer to the instructions for the remote
control system.
Note: Use an ohmmeter or continuity tester to check for
shorts or open leads in the wiring harnesses
before replacing the controller circuit board or
other system components.
Follow the instructions in Section 3.3 to remove the
generator set from the enclosure, if necessary. Service
fixtures are required if it is necessary to run the
generator set outside of the enclosure. See Section 5.1.
Maintain a record of repairs and adjustments performed
on the equipment.
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) Place the generator set start/stop
switch in the STOP position. (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.
Hazardous voltage.
Can cause severe injury or death.
Only authorized personnel should
open the enclosure.
(600 volts and under)
WARNING
Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
are in place.
Moving rotor.
WARNING
Grounding electrical equipment. Hazardous voltage can
cause severe injury or death. Electrocution is possible
whenever electricity is present.
Open the main circuit
breakers of all power sources before servicing the equipment.
Configure the installation to electrically ground the generator
set and related equipment and electrical circuits to comply with
applicable codes and standards. Never contact electrical
leads or appliances when standing in water or on wet ground
because these conditions increase the risk of electrocution.
