HF reactor module: Overtemperature or fan failure

Was bedeutet 237312 ?

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.

• Impending or intermittent fan failure (e.g., worn bearings, vibration, motor intermittently stalling) on the HF reactor module.
• Partial blockage of cooling air paths due to dust buildup or obstruction in the cabinet.
• Brief, intermittent overload conditions causing the reactor to temporarily heat up.
• Elevated ambient temperature in the cabinet, approaching the reactor's temperature limit.
• Early stage degradation of thermal paste or poor contact between internal components and the heat sink.

1. 1

   Inspect the HF reactor module's fan during operation to confirm it is rotating freely and at full speed.

2. 2

   Clean the air filters and cooling vents of the control cabinet and the reactor module itself.

3. 3

   Monitor the load on the drive system (r0067) to identify transient overloads; reduce load if necessary.

4. 4

   Measure the internal cabinet temperature and compare it to the module's specified maximum operating temperature.

5. 5

   Check the reactor's internal temperature sensor feedback (r0037, if available) against ambient readings and expected values.
