HF reactor module: Overtemperature or fan failure

What does 237312 mean?

This alarm indicates that the reactor module has detected an overtemperature condition or a fan failure. The immediate causes can include a disconnected or defective connector between the reactor and damping module, a malfunctioning reactor module fan, or an excessively high ambient temperature. If this alarm persists for longer than 30 seconds, it will escalate to fault F37313, indicating a more critical condition. Continued operation under these conditions risks permanent damage to the module.

Complete Troubleshooting Guide

1. 1

   Check the connector between the reactor and damping module to ensure it is securely connected and not defective. Re-seat or replace if necessary.

2. 2

   Inspect the fan of the reactor module for proper operation (e.g., rotation, unusual noise). Replace the fan if it is faulty or damaged.

3. 3

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