Display
Special Pos not reached Positioning fault of air actuator
Special Pos not reached Positioning fault of fuel actuator
Special Pos not reached Positioning fault of auxiliary actuator 1
Special Pos not reached Positioning fault of auxiliary actuator 2
Special Pos not reached VSD has not reached the speed
Special Pos not reached Positioning fault of auxiliary actuator 3
Code for VSD Module Fault Basic unit has detected a fault in
connection with the VSD module
Speed Acquisition faulty Internal VSD module test was not
successful
Wrong Direction of Rotation Fan rotates in the wrong direction
Speed Acquisition faulty Pulse sequence and length at the speed
input were different from those anticipated
Standardization canceled Fan was not able to keep the standardized
because of VSD speed at a constant level
Standardization canceled Air actuator has not reached the prepurge
because of Air Actuator position. For this reason, speed
standardization is not possible
Speed Test was not successfully Internal VSD module speed test was not
completed successful
Meaning for the LMV5x system Troubleshooting
If fault occurs sporadically: Check CAN bus wiring.
Improve EMC.
If fault occurs constantly: Replace the defective basic unit
Check to see if the motor's direction of rotation is correct.
Check to see if the sensor disk on the motor is mounted the
correct way.
Change live conductor on the fan motor or check
parameterized direction of rotation on the VSD and correct,
if necessary
Check to see if sensor disk and speed sensor are correctly
mounted.
Check if the distance of the inductive sensor is correct.
Check if the inductive sensor is correctly connected
Check if motor runs.
Check if the inductive sensor is correctly connected.
Check if distance of inductive sensor is correct
Check to see if all air-influencing actuators travel to the
prepurge position.
Check to see if the relevant actuators are mechanically
overloaded or replace defective actuator, if necessary.
Check power supply to the actuators
