Error relay supervision
Check for voltage feeding back on the output given by the diagnostic code. Fix the wiring
error / defective component causing the voltage feedback and reset the fault.

External power supply NO contact (fuel
valve 1 - X8-02.1)

Error relay supervision
Remove the wire from fan output terminal X3-05.1 and perform the following two tests:
1. With power connected to the LMV3 and the LMV3 in standby, ensure there is no voltage
on fan output X3-05.1.
2. With no power connected to the LMV3, ensure there is no continuity between fan output
X3-05.1 and neutral.
If either test fails, replace the LMV3. If both tests are passed, reset the fault.

Internal error relay control
If the fault occurs continuously, replace the LMV3.

Internal error relay control
On software version V03.10, if this error occurs during standardization of the VSD,
temporarily deactivate the alarm in the case of start prevention (set parameter 210 = 0),
reset the fault, and re-standardize. Otherwise, if the fault occurs continuously, replace the
LMV3.
