Figure 4-9. Wiring Diagram— Fault #1 or Fault #2 message

Fault #1 Or Fault #2 Message

The external fault function can be used to identify a
problem with the emergency power system, or a support
device of the emergency power system. A dry relay
contact can be used to signal a fault, such as a Ten Relay
Dry Contact Kit, sold as an accessory with the generator
set.

NOTE: The contact kit must be a dry contact, the logic
controller supplies its own voltage source.

The fault messages are used to monitor accessory
components. A fault message appears on the LCD when
an accessory is grounding the pin to which it is
connected. See Figure 4-9.

1. If a FAULT #1 message appears on the LCD, check

TB-DC1-8.

a. If there is an accessory connected to TB-DC1-8,

disconnect the accessory. Press the RESET

MENU key. If the message disappears, the logic

board is performing correctly. The FAULT #1

message is caused by the connected accessory.

b. If there is not an accessory connected to

TB-DC1-8, remove power from the logic board

and disconnect the P2 ribbon cable connector

from the power supply board. Using an

ohmmeter, connect one test lead to P2-7 on the

power supply board. Connect the other test lead

to TB-DC1-34. If the resistance is low, replace

the power supply board. If the resistance is high,

replace the logic board assembly.

2. If a FAULT #2 message appears on the LCD, check

TB-DC1-11.

a. If there is an accessory connected to

TB-DC1-11, disconnect the accessory. If the

message disappears, then the logic board is

performing correctly.

b. If there is not an accessory connected to

TB-DC1-11, remove power from the logic board

and disconnect the P2 ribbon cable connector

from the power supply board. Using an

ohmmeter, connect one test lead to P2-8 on the

power supply board. Connect the other test lead

to TB-DC1-34. If the resistance is low, replace

the power supply board. If the resistance is high,

replace the logic board assembly.
