Cause : System temp comes when you receive an alarm indicating that one or more system temperature measurements are too high, it's crucial to address the issue promptly to prevent damage to equipment and ensure the safety of the system.

Here's a step-by-step approach to handling this situation:

  1. Immediate Action: Take immediate action to mitigate the risk of overheating. Shut down the affected equipment or system if necessary to prevent further temperature rise and potential damage.

  2. Identify High-Temperature Areas: Determine which components or areas of the system are experiencing elevated temperatures. Use temperature monitoring equipment, such as infrared thermometers or thermal imaging cameras, to identify hotspots and areas of concern.

  3. Check Ventilation and Cooling Systems: Inspect the ventilation and cooling systems of the affected equipment or system. Ensure that cooling fans are operating correctly, air vents are not blocked, and airflow is sufficient to dissipate heat effectively.

  4. Remove Heat Sources: Identify and remove any external heat sources or obstructions that may be contributing to the high temperatures. This could include equipment placed too close together, exposure to direct sunlight, or blocked airflow from nearby objects.

  5. Inspect Heat Dissipation Components: Check heat sinks, heat exchangers, and other heat dissipation components for damage, dust buildup, or improper installation. Clean or replace components as necessary to improve heat dissipation efficiency.
