HF reactor module: Overtemperature or fan failure
Siemens · FC1765DC Controller
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.
Complete Troubleshooting Guide
- 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
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
Verify that the ambient temperature surrounding the module is within the permissible range and that there is adequate airflow for cooling.
