Error numbers

Possible errors of the MSE6-E2M are divided into three error classes with different priority, depending
on the seriousness of the error. If an error occurs, the system error LED (SF LED) will flash depending on
the error class.

Error class 1 (simple error): 1 * flash, pause
Error class 2 (error)
Error class 3 (serious error): 3 * flash, pause
Tab. 8.2 LED SF
If several errors occur together, the error with the highest priority will have precedence. This means
that:
– The system error LED flashes according to the higher priority
– The number of the error with the higher priority will be entered in the system diagnostic data under
function number 1938 (error number).
Within an error class, errors of modules with a lower module number have higher priority. For example,
errors of module number 0 have the highest priority within an error class. Errors of module number 1
have the second highest priority, etc.
