Resolving safe-state mode with SPN and FMI codes

42 |

Danfoss | October 2018

In order to resolve safe-state mode with this method, SPN and FMI codes must be obtained and referred

to in the User Manual. There are two ways to obtain SPN and FMI codes: through the error history pages

or the error occurrence counter page.

1. Go to System Navigator > Diagnostics > SEHS Error History_Main (or _Safety).

The blue arrow shows the most recent error in the list.

After 16 errors are recorded, new errors are written over previous errors starting at Error Record 1.

2. Click the corresponding "Error Record" button to see more details on the error. This will display the

Suspect Parameter Number (SPN) and the Failure Mode Identifier (FMI) of the error.

3. Search the SPN in the User Manual and then look for the correct FMI to learn more about the error

and find possible root causes.
