Fault Codes
Code Trip Cause Comments
FT Fast Trip Circuit breaker channel has hard short
I2 I2T Trip Circuit breaker channel has soft fault
FO Fail Open Circuit breaker switch failed open circuit
FS Fail Short Circuit breaker switch failed short
ECBU Fault Indications (Red LEDs)
Red LEDs Indication Comments
All On Process Not
Running
ECB Channel x On FT or I2 ECB channel tripped; ECB channel x LED continuously illuminated
ECB Channel x Flash
@2 Hz
FO or FS ECB channel tripped; channel x LED flashes
This condition will usually mean that the breaker is unresponsive
to the override switches and the green LED will either remain on
or off depending on the fault.
All three of these Analog subsystem faults are reported via unique blink codes using the red LEDs. One or more
blink codes are displayed on those LEDs which are not indicating a trip or ECB fault. Blink codes are indicated by
some number of fast blinks followed by an off period. The system cycles through the blink code for each fault
which is present.
If all three faults are present there will be a sequence of xix blinks and three pause, as in: blink - pause - blink blink
- pause, blink, blink, blink - pause, which then repeats.
Single Blink – Pause
–
Repeat
Voltage Monitor
fault
If the voltage monitor inputs cannot be read, the ECB fault
detection described in the previous paragraph is disabled. Voltage
will continue to be reported on the NMEA bus but it may be
incorrect.
Blink followed by an off period
Analog subsystem fault – vSense
Two Blinks – Pause
–
Repeat
Current Monitor
fault
If the current monitor inputs cannot be read the I2T trip detection
is disabled. Current will continue to be reported on the NMEA bus
but it may be incorrect.
Blinks followed by an off period
Analog subsystem fault - iSense
Three Blinks – Pause
–
Repeat
Analog GPI fault If the analog GPIs cannot be read, any actions programmed in the
Configuration Data Base based on analog GPIs are disabled.
Blinks followed by an off period
Analog subsystem fault – gpi inputs
