Temperature Difference Exceeded
Beckhoff · EL6900 Operating Instructions
¿Qué significa 0007 hex ?
This diagnostic code (found within FA00:03 Temperature error) indicates that the temperature difference between the internal measuring points (e.g., Temperature Primary MC and Temperature Secondary MC, FA80:01 and FA80:02) has exceeded its permissible threshold. A significant temperature differential can suggest localized heating or cooling issues within the terminal, potentially leading to component stress or operational instability.
Causas comunes
- The difference between two measured temperature points (e.g., inlet vs. outlet, or ambient vs. internal) exceeds the acceptable threshold.
- Imbalance in the thermal management system.
- Faulty temperature sensor leading to an erroneous differential reading.

- 1
Check the diagnostic object FA80:01 (Temperature Primary MC) and FA80:02 (Temperature Secondary MC) to identify the specific temperature values and calculate the difference.
- 2
Verify the mounting and heat dissipation of the EL6900 terminal for even temperature distribution.
- 3
Inspect the terminal internally for any debris or obstructions that might impede heat transfer or cause localized heating.
