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 # Trim function: Maximum time for trim limit exceeded
A trim limit was met for the maximum allowable time. See diagnostic
codes for more information.
0 Lower limit trim function
The VSD trim signal was lower than allowed by the minimum trim limit
(parameter 547) for a time period longer than the maximum time allowed
(parameter 551).
1 Upper limit trim function
The VSD trim signal was higher than allowed by the maximum trim limit
(parameter 548) for a time period longer than the maximum allowed
(parameter 551).
10 Fuel 1: Lower limit trim function
The VSD trim signal was lower than allowed by the minimum trim limit
(parameter 567) for a time period longer than the maximum time allowed
(parameter 571).
11 Fuel 1: Upper limit trim function
The VSD trim signal was higher than allowed by the maximum trim limit
(parameter 568) for a time period longer than the maximum allowed
(parameter 571).
Any # Trim function: Failed the analog input test
A fault occurred during the analog input test. See diagnostic codes for
more information.
0 Analog value standby
If the analog input test is enabled, the LMV3 looks for 12mA to be present
on terminal X64 during standby. Check parameter 916 to ensure that the
input signal lies in the permissible range of -1%...+1%. Setting parameter
530 to a value other than 2 or 4 disables the analog input test.
1 Analog value prevention
If the analog input test is enabled, the LMV3 looks for 4mA to be present
on terminal X64 during prepurge. Check parameter 916 to ensure that the
input signal lies in the permissible range of -16%...-14%. Setting parameter
530 to a value other than 2 or 4 disables the analog input test.
165 Any # Internal error
166 0 Internal error watchdog reset

If the fault occurs continuously, replace the LMV3.
