*AC Phase*
L1 and L2 miswired/exchanged. 1. Check L1 and L2 for proper line phasing.
Fault 105
*Call Service*
Relay Module self-test failure. 1. Reset and sequence the CB 780/CB 784.
2. If fault reappears, remove power from the device,
reapply power, reset and sequence the
CB 780/CB 784.
3. If fault persists, replace the relay module.
Fault 106
*Call Service*
Relay Module self-test failure. 1. Reset and sequence the CB 780/CB 784.
2. If fault reappears, remove power from the device,
reapply power, reset and sequence the
CB 780/CB 784.

Fault 107
*Call Service*
Relay Module flame signal
cross-check failure.
1. Reset and sequence the CB 780/CB 784.
2. If fault reappears, remove power from the device,
reapply power, reset and sequence the
CB 780/CB 784.
3. If fault persists, replace the relay module.
Fault 109
*Call Service*
Negative cycle test failed; earth
ground absent or line voltage
phasing improper.
1. Assure that a good earth ground connection
exists at the installation site and that all earth
ground connections are complete and correct.
2. Assure that the CB 780/CB 784 and all loads
operate at the same line voltage phase.
3. Reset and sequence the CB 780/CB 784.
4. If fault persists, replace the relay module.
Fault 110
*Call Service*
Configuration jumpers differ
from stored values.
1. Inspect the jumper connections. Assure they
match the original selection and clipped jumpers
were completely removed.
2. Reset and sequence the CB 780/CB 784.
3. If fault persists, replace the relay module.
4. Configuration jumpers must be selected prior to
200 hours of operation. If configuration jumpers
are changed after 200 hours of operation, lockout
110 occurs.
Fault 111
*Call Service*
Relay Module configuration
jumper test failure.
1. Inspect the jumper connections. Assure they
match the original selection and clipped jumpers
have been completely removed.
2. Reset and sequence the CB 780/CB 784.
3. If fault persists, replace the relay module.
Fault 112
*Call Service*
Relay Module self-test failure. 1. Reset and sequence the CB 780/CB 784.
2. If fault persists, replace the relay module.
Fault 113
*Call Service*
Relay Module self-test failure. 1. Reset and sequence the CB 780/CB 784.
2. If fault persists, replace the relay module.
Fault 114
*Call Service*
Relay Module self-test failure. 1. Reset and sequence the CB 780/CB 784.
2. If fault persists, replace the relay module.
Fault 117
*Call Service*
