Environment Error: Valid temperature difference between μC1 and μC2 exceeded
Beckhoff · EL2912 TwinSAFE
¿Qué significa 7 ?
When LED Diag 1 is off and LED Diag 2 flashes with code 7 (400ms ON / 400ms OFF), it indicates that the temperature difference between microcontrollers μC1 and μC2 has exceeded a valid threshold. This environment error could point to uneven cooling, a sensor malfunction, or an internal fault causing one μC to heat differently than the other, potentially compromising the integrity of dual-channel temperature monitoring.
Causas comunes
- Significant temperature difference between the two internal microcontrollers (μC1 and μC2).
- Uneven heat dissipation within the device.
- Faulty temperature sensors associated with μC1 or μC2.
- Improper mounting leading to thermal gradients.
Pasos de reparación & Lista de verificación
Haga clic en los pasos para seguir su progreso.
- 1
Read internal temperature readings for μC1 and μC2 from diagnostic parameters (e.g., P7-01, P7-02).
- 2
Ensure adequate airflow around the device to equalize internal temperatures.
- 3
Verify the integrity of the device's thermal paste or heat sinks.
- 4
Inspect temperature sensor connections if accessible.
