TP-7045 3/18c 65 Section 9 Paralleling Generator Sets
Step Potential Cause Explanation Troubleshooting
Fault: Close Attempt
Fault: Fail to Close
(Continued)
7 Breaker is not powered The 24V electronics on the circuit breaker
require an external 24V source on a 12V
generator.
Verify the 24V input which exists on
paralleling generators is receiving 24VDC
in the correct polarity.
8 Wiring to power is not
complete
There is no voltage to the CB close relay
on this circuit breaker.
Connect the supply to the CB close relay to
either 24V from wire #70 or an external
24VDC supply (with battery storage).
9 Breaker status feedback
is not valid, no bus
sensing
The breaker closes but the controller does
not see a change in status. The controller
cannot see the bus is energized as the bus
sensing is not connected correctly on any
generators on the network.
Verify the wiring on the circuit breaker to
ensure that it is connected correctly. Verify
bus wiring for all nodes. Verify the
generator output is connected to the line
side of the generator breaker.
Fault: CB Status
Warning: Bus Sensing Not Connected
1 Breaker status feedback
is not valid, no bus
sensing
The breaker closes but the controller does
not see a change in status. The controller
cannot see the bus is energized as the bus
sensing is not connected correctly on this
generator, but another generator is
connected.
Verify the wiring on the circuit breaker to
ensure that it is connected correctly. Verify
bus wiring for this generator.
Fault: CB Status or Continuous Breaker Cycling
1 Breaker status feedback
is not valid
The breaker closes but the controller does
not see a change in status. The controller
sees the bus is now live.
Verify the wiring on the circuit breaker to
ensure that it is connected correctly.
