Overvoltage at backup power supply
â–¶ How to fix
Check voltage level at backup supply (30_1). Trouble shoot backup supply voltage circuit
What you'll see
No driver-visible symptom recorded.
System reaction
Active load and actions that are supported by backup power supply are canceld. New activations and actions are rejected.
Diagnostic depth
Detection
Evaluated cyclically every 4ms. Voltage at pin 30_1 > parameter voltage threshold
Possible cause
Voltage level too high
