hello colleagues, could you help me about the issue please.
I have a big problem on gcs222.

On gecb side: 200,201, 218 faults
On gdcb drive side: 514
I replaced PRS sensor, magnets, gecb pcb, canceled ADO parameter. Checked 1LV, 2LV, UIS, DIS signals. But the errors occur almostly every travel. but sometimes work without problems. also errors on both direction and at every floor.
4 stops, 1 m/s, 2 entrance door, 2013

Thank you for your support.
