Cause : Converter cooling faulty (active in all operating states) comes when the heat sink temperature is higher than the permissible value (depending on the MLFB).
- The monitoring function is activated 6s after the electronics supply is connected.

(The current heat sink temperature is indicated at parameter r013 and on connector K050)
