If your Siemens Protection Device relays aren't communicating in a ring network, verify that all relays are powered up with the auxiliary power supply and have unique addresses. Also, in self-powered mode, check that the CT input current is above 1.62 * I (1-phase) or 0.6 * I (3-phase).
What to do if Siemens Reyrolle 7SR46 Protection Device relay does not power up?
If your Siemens Protection Device relay does not power up, check that the correct auxiliary AC or DC voltage is applied with the correct polarity. Ensure that the phase connections are based on the terminal diagram and that CT power is applied. Also, check the USB port if the relay is connected with USB power, and verify the battery healthy voltage if it's powered by battery.
Why is the HEALTHY LED off or LCD not displaying on my Siemens Reyrolle 7SR46 Protection Device?
If the HEALTHY LED is off or the LCD is not displaying on your Siemens Protection Device, check the minimum phase currents in the absence of auxiliary voltage. Also, review the error messages and error codes under IRF in the INSTRUMENT MODE.
Why do binary inputs not work on my Siemens Protection Device?

What to do if external trip (ET) input does not work on Siemens Reyrolle 7SR46 Protection Device?
If the external trip (ET) input on your Siemens Protection Device is not working, check whether the device is operating on CT power or auxiliary power and ensure it is in a healthy condition. Short the ET terminals with a resistance wire and ensure that the line wire resistance is less than or equal to 20 ?.
How to troubleshoot low/critical battery indication on Siemens Protection Device?
If you see a low or critical battery indication on your Siemens Protection Device, check whether the paper strip between the battery clip and battery has been removed. Also, ensure the battery is connected with the correct polarity and verify the battery healthy voltage.
