HF reactor module: Overtemperature or fan failure

What does 237313 mean?

This fault is triggered when alarm A37312 (overtemperature or fan failure in the reactor module) persists for more than 30 seconds, leading to an OFF2 reaction and stopping the drive. The underlying issues are typically a disconnected/defective connector between the reactor and damping module, a faulty reactor module fan, or an ambient temperature that exceeds safe limits. This fault indicates a critical condition requiring immediate attention to prevent severe damage to the HF reactor module and ensure system safety.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify that the ambient temperature surrounding the module is within the permissible range and that there is adequate airflow for cooling.
