Fault Text Description
The primary controller has lost communication with the secondary
LossOfComm2 controller. (A secondary controller was detected, then
communication was lost.)
This generator has absorbed more than 25% reactive power
LossOfField
(magnetic excitation current) for 20 seconds.
The generator has verified that the metering is connected
MeteringOk correctly and that the direction is consistent with expected power
direction.
This generator does not know if the metering is connected or the
MeterUnknown orientation of the connection. This means that the generators
can't share load accurately until this information is known.
The generator has applied load (using the other generator) and
NoCurrent
has observed no current on the power sensing inputs.
The generator has been attempting to synchronize for over 2
SyncFailure
minutes without success.
 For paralleling system troubleshooting and service, contact an authorized dealer.

Description
This generator has been stopped by generator management because it is not presently needed to
supply the load. The generator is available and will start if it is needed again.
The contactor has been forced to open to protect one of the generators or the customer's load.
The generator is actively trying to match frequency, voltage and phase with that of the paralleling
bus.
The generator is actively trying to transfer load from itself to the other generator.
Possible Causes *
RBUS disconnected, secondary controller
battery disconnected, updating firmware in
secondary controller, or intermittent RBUS
connections.
Generator voltage on this generator is not
calibrated correctly.
Generator voltage on other generator is not
calibrated correctly.
Bus voltage on this generator is not
calibrated correctly.
Bus voltage on the other generator is not
calibrated correctly.
Status message indicates that the CT is
connected to the generator correctly.
System commissioning and startup not yet
complete. See the APM instructions.
The CT is not connected to the controller.
The output leads from the generator do not
go through the CT in the correct direction.
See the APM instructions.
Generator is hunting.
Advanced speed control settings need
adjustment.
Load is changing frequently to disturb the
online generator.
