HelloSalatiM, One possibility is that the chosen CT ratio of 7SJ is not same as the field CT ratio. For example if the CT ratio of 7SJ is XX/1 A and the field CT ratio is XX/5 A then the Errore red led will lit. To know the CT ratio of the 7SJ; in DIGSI right click on the 7SJ file and select Object Properties from the context menu then the Properties-Siprotec Device dialog will open, click on MLFB tap, there you can see infront of Nominal Current the CT ratio. If the CT ratio is not same as the field CT ratio then you need to change the CT ratio of 7SJ by changing the jumper inside the 7SJ hardware and for doing this you need to read the 7SJ manual. If the CT ratio is correct then may be Re-Initialize the device by using DIGSI may solve the problem. See attached file:
