Meaning for the LMV5x System
Fault with Positioning an Actuator or VSD Speed
Running time fault of actuators or VSD.
The diagnostic value is made up of the following faults or their
combinations (the individual diagnostic codes are added up in
hexadecimal format)
Running time fault of air actuator
Running time fault of auxiliary actuator 1
Running time fault of auxiliary actuator 2
Running time fault of VSD
Running time fault of auxiliary actuator 3
Basic unit has detected that one or several actuators (incl. VSD
module) has / have not reached the special position pertaining
to the phase
The diagnostic value is made up of the following faults or their
combinations (the individual diagnostic codes are added up in
hexadecimal format)
Positioning fault of air actuator
Positioning fault of active fuel actuator
Positioning fault of auxiliary actuator 1
Positioning fault of auxiliary actuator 2
VSD has not reached the speed
Positioning fault of auxiliary actuator 3
VSD quick shutdown, as the difference between the speed
setpoint and the actual speed exceeds the value permitted in
the TolQuick Shutdown parameter.

Corrective Action
1) Check parameters TimeNoFlame and
OperatRampMod . These should be set to values
greater than the ramping time of the attached actuators
or VSD.
2) Check connected actuators to determine if their
torque rating is being exceeded (stuck damper or valve,
etc...).
3) Check the two 12V fuses located under black covers
on the right side of the LMV5.
4) Check the CANBus power supply (blue or black
transformer) terminal SEK2. Pin 1 and pin 4 should
have 12VAC to reference ground which is pin 2.
Voltage between pin 1 and pin 4 should be 24VAC.

Voltage between pin 1 and pin 4 should be 24VAC.
4) If a VSD is being used, check for filters, damping,
and / or delays on the input signal to the VSD. The
VSD should respond to the input signal in a linear
fashion. See Error Code 15 for more information.
