Error Question
How do I test tube rotor impedance on the Brivo XR285amx?
Short Answer
The Tube Rotor Impedance diagnostic measures the tube stator winding impedance.
Possible Causes
Open/shorted stator winding; tube rotation cable issue; rotor-board fault.
Troubleshooting Steps
Run Tube Rotor Impedance. If abnormal, inspect the rotation cable, then measure stator Common-to-Phase and Common-to-Auxiliary resistance and isolation at the tube side.
