Meaning for the LMV5x system
Fault with Actuator (VSD) Positioning, Actuator (VSD) Run Time
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 1 / 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 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

Corrective action
1) Check parameters (TimeNoFlame) and
(OperatRampMod). These should be set to values
greater than the ramping timeof the attached actuators
or VSD.
2) Check connected actuators to determine if their
torque rating is being exceed (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) Pin 1 and Pin 4 should have 12VAC to
reference ground which is pin 2. Voltage betwen Pin 1
and Pin 4 should be 24VAC.

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.
