Owner's Manual for Power Zone Pro Sync
Description
The Power Zone Governor
module #x failed to respond with
an acknowledge message to a
CAN bus message from the Main
Controller. The Main Controller
resends the CAN bus message a
number of times while waiting for
an acknowledge response before
triggering this warning. The
Governor module may be an
incompatible version with the
Main Controller or may have
corrupted firmware/settings.
The Power Zone AVR module #x
failed to respond with an
acknowledge message to a CAN
bus message from the Main
Controller. The Main Controller
resends the CAN bus message a
number of times while waiting for
an acknowledge response before
triggering this warning. The AVR
module may be an incompatible
version with the Main Controller
or may have corrupted firmware/
settings.
The Power Zone Battery Charger
#x failed to respond with an
acknowledge message to a CAN
bus message from the Main
Controller. The Main Controller
resends the CAN bus message a
number of times while waiting for
an acknowledge response before
triggering this alarm. The Battery
Charger module may be an
incompatible version with the
Main Controller or may have
corrupted firmware/settings.
A module with an unknown
address failed to respond with an
acknowledge message to a CAN
bus message from the Main
Controller. The Main Controller
resends the CAN bus message a
number of times while waiting
for an acknowledge response
before triggering this warning. It
may be harder to troubleshoot the
cause of this warning since the
address of the module is
unknown.
