LMV5 QSG Rev 4
Meaning for the LMV5x system
Fault with Connected actuators
Temperature warning and shutdown
Actuator turns in the wrong direction
Actuator operates with too short a ramp time,
or with an angular rotation that is too long for the ramp time
Timeout during A/D conversion
Fault during ADC test
Fault during A/D conversion
Actuator is outside the valid angular
rotation (0-90°) or linearization data are faulty
CAN fault
CRC fault of a parameter page
Page too long open
Page disrupted
Invalid parameter access
Fault during copying of parameter page
External plausibility fault. This type of fault covers possible
faults occurring due to invalid presettings in the drive
commands. In response, the presettings will be ignored
Internal plausibility fault. This type of fault covers possible faults
that can occur due to strong EMC impact
Sec 5 Pg 32
Corrective action
Check the housing temperature of the Air actuator. Max
housing temperature 140 F
Verify that the air damper is not bound. A bound air
damper will cause the actuator to trip on overcurrent.
During this short trip the actuator can be momentarily
pushed backwards by torsional effects.
1) Match ramp time to the slowest connected actuator
(SQM48.4 30 sec, SQM48.6 60sec.)
2) Check the CanBus power supply. Verify fuses FU2
and FU3 are ok. Verify CanBus is not overloaded. (See
Section 3)
1) If fault occurs sporadically: Improve EMC.
2) If fault occurs constantly: Replace Air Actuator.
Check to see if actuator is within the valid positioning
range (0-90°) When the actuator is not powered, it could
be moved out of the valid positioning range. Take power
off the actuator and position shaft back within the valid
positioning range.
1) 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...
2) Check each CANBus Connector to ensure proper
termination (no conductors exposed on the back of the
plug)
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
1) Check the paramters related to special positions. The
special positions of each activated actuator should be
programmed between 0 to 90 degrees.
1) If fault occurs sporadically: Improve EMC.
