Cause:
- the brake is not detected as open at the start of the trip
- the brake does not open
- the brake release monitoring does not switch
Remedial action:
- check the brake release monitoring
- check the control of the brakes
- check the brake opening time
- check the parameter "T_2" in the "Start" menu and increase it if necessary
- check the parameterisation of the brake release monitoring ("Monitoring" and "Control system" menues)
