● Closing of brake for a 1 signal "unconditionally close holding brake" (p0858)
● Binector inputs for opening or closing the brake (p1218, p1219)
● Connector input for the threshold for opening and closing the brake (p1220)
● OR/AND block each with two inputs (p1279, r1229.10, r1229.11)
● Holding and service brakes can be activated
● Monitoring of the brake feedback signals (r1229.4, r1229.5)
