5.2.2 Separate valves for vehicles with a conventional braking system
On vehicles equipped with LSV regulators but without an ABS system, autonomous braking is effected in the same
manner as for vehicles fitted with an ABS braking system. In the system diagram (see 4.2.1), only the two ABS
solenoid valves (10) are missing.
On vehicles with a conventional braking system without an LSV regulator, the output pressure is instead fed into the
control input of the conventional relay valve via a two-way valve.
5.2.3 Separate valves for vehicles with an EBS braking system
When the driver actuates the brake signal transmitter (not shown here) on a towing vehicle with an EBS braking
system, the braking pressure is applied directly to the Tristop cylinders from the outputs of the axle modulator (2) in the
usual manner.
