Corrective Action
1) Reset the LMV5
2) If fault occurred after changing a parameter, check
the parameters that were last changed.
3) If fault cannot be rectified by the reset: Restore
parameters form the AZL to the LMV5
4) Replace the LMV5
None
If fault occurs sporadically, reduce electrical noise.
If fault occurs continuously, replace LMV5.
This lockout occurs when escape and enter on the AZL
are pressed simultaneously. This lockout also occurs
when the remote reset X4-01.4 is energized when an
alarm condition does not exist.
If fault occurs sporadically, reduce electrical noise.
If fault occurs continuously, replace LMV5.
1) This fault occurs when an un-addressed actuator is
connected to the CANBus. Addressing the actuator
should eliminate the fault.
2) Check CANBus cabling. Ensure that all cable shields
(screens) which are located in the cable sheath are
terminated correctly at each actuator, O2 module, and
at the LMV5x...
3) Check each CANBus connector to ensure proper
termination (no conductors exposed on the back of the
plug)
4) If fault occurs sporadically: Reduce electrical noise.
5) If fault occurs constantly: Replace actuator according
to diagnostic code.
