HF reactor module: Overtemperature or fan failure

What does 237312 mean?

The reactor module has detected an overtemperature condition or a failure in its cooling fan. This alarm serves as a warning for a potential thermal issue. If this alarm persists for longer than 30 seconds, it will escalate to fault F37313 (likely 237313), indicating a more critical and sustained thermal problem that requires immediate attention.
