Cause : Mechanical brake control alarm. Alarm is activated, eg, if brake acknowledgement is not as expected during brake opening.
Programmable fault: 35.09 BRAKE FAULT FUNCTION
Check mechanical brake connection.
Check mechanical brake settings, parameters
35.01...35.08.
To determine whether problem is with
acknowledgement signal or brake: Check if
brake is closed or open
