Maximum Temperature Exceeded

What does 0005 hex mean?

This diagnostic code (found within FA00:03 Temperature error) indicates that the internal temperature of the device has exceeded its maximum permissible operating limit. This condition can affect the primary and secondary microcontrollers (μC1, μC2) and may lead to component degradation or terminal shutdown.

• Ambient temperature or internal component temperature has exceeded the predefined safe operating limit.
• Overload condition causing excessive heat generation.
• Cooling system malfunction (e.g., fan failure, blocked ventilation) leading to high temperatures.

Click steps to track your progress.

1. 1

   Check the diagnostic object FA80:01 (Temperature Primary MC) and FA80:02 (Temperature Secondary MC) to monitor current internal temperatures.

2. 2

   Verify the ambient temperature around the EL6900 terminal does not exceed the specified operating limits.

3. 3

   Ensure proper airflow around the EL6900 terminal by checking for obstructions in the cabinet or around the device.
