Note: Diagnostic codes are additive. If a diagnostic code appears that is not on this list, it is a combination of multiple diagnostic codes.
Any # Control range limitation of VSD
1 Control range limitation at the bottom
80
2 Control range limitation at the top
81 1 Interrupt limitation speed input
Any # Error during VSD's speed standardization
82 1 Timeout of standardization (VSD ramp down time too long)
2 Storage of standardized speed not successful

Meaning for the LMV3 System
A VSD speed error occurred. See diagnostics codes for more information.
This indicates that the LMV3 has decreased its signal to the VSD as much as
possible and the motor RPM is still too high.
1) Increase VSD / LMV3 ramp times.
2) Increase VSD braking if possible.
3) Ensure that the VSD and LMV3 are configured for the same analog
signal (0-10 VDC).
4) Re-standardize the speed. Be sure to check combustion after the re-
standardization.
This indicates that the LMV3 has increased its signal to the VSD as much as
possible and the motor RPM is still too low.
1) Increase VSD / LMV3 ramp times.
2) Check for filters, damping, or delays on the input signal to the VSD. The
VSD should respond to the input signal in a linear fashion.
3) Check speed sensor on motor for correct installation, especially the gap
between the sensor and the speed wheel.
4) Ensure that the VSD and LMV3 are configured for the same analog
signal (0-10 VDC).
5) Re-standardize the speed. Be sure to check combustion after the re-
standardization.
The LMV3 has detected an interruption on the speed input. Decrease the
electrical noise on the speed sensor wires. If the fault occurs continuously,
replace the LMV3.
An error occurred while attempting to standardize the speed of the VSD.
See diagnostic codes for more information.
Standardization timed out because the VSD took too long to ramp down at
the end of the standardization. Either decrease the ramp down time in the
VSD or increase the setting of parameter 523.
Press the info button with any other button to cause a manual lockout,
then reset the fault and attempt to standardize again.
