Opening the brake

Overview
The following describes how you can set the command for the forced opening of the holding
brake.
Parameterizing the "Open brake" command
To parameterize the command for the forced opening of the holding brake, interconnect the
signal sink "Unconditionally open holding brake" (p0855) for the command that is to
unconditionally open the brake.
The brake opens when this signal or the internal signal "Open brake" has the value "1".
Note
Prioritization of the commands
The "Unconditionally close brake" signal has a higher priority than the "Unconditionally open
holding brake" signal.
