HF reactor module: Overtemperature heat sink

What does 237311 mean?

The heat sink temperature of the HF reactor module has surpassed its maximum permissible limit. This condition is often due to insufficient cooling (e.g., fan malfunction), an overloaded system causing the module to generate excess heat, or an ambient temperature that is too high for safe operation. Persistent high temperatures can lead to damage and failure of the reactor module.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Evaluate and reduce the motor load if it is exceeding the module's capacity or causing excessive heat generation.

2. 4

   Ensure the alarm threshold for alarm A05000 has been undershot before attempting to acknowledge this fault.
