Cause : SBT brake closing time exceeded comes when the maximum time (11 s) to close the brake during the brake test was exceeded.

Alarm value (r2124, interpret binary):

Bit 0 = 1: Internal brake was not able to be closed.
Bit 1 = 1: External brake was not able to be closed.

- When using an external brake, check that the feedback signal "brake closed" is correctly interconnected with the control word of the brake test (p10230.5, p10235.5).
- When using an internal brake with external feedback signal, check whether the feedback signal is correctly interconnected with the extended brake control.
- Carry out a safe acknowledgment.
- restart the brake test (p10230.1, p10235.1).
