Coupling Heads - BPW ECO Tronic EBS Operating And Installation Instructions

5.1.1 Coupling heads

Applications
The coupling heads of the two line brake system, red for
"supply" and yellow for "brake", are installed to connect the
supply and brake lines between the vehicle or the tractor unit
and trailer vehicles. They are constructed in such a way that
they cannot be wrongly connected.
Automatic coupling heads are installed on the towing vehicle
(commercial vehicle or trailer rear connection) to establish
connections to towed vehicles.
The coupling head with integrated fi lter simultaneously protects
the compressed air braking system from soiling.
The coupling heads meet the requirements of ECE/EC and
DIN-ISO 1728.
Mode of Operation
The coupling heads are connected to each other up to the stop
dog. This prevents a supply line coupling head being connected
to a brake coupling head. This means they cannot be wrongly
connected.
Installation Guidelines
The supply coupling head (red) is installed in the driving direction
to the right and the brake coupling head (yellow) to the left. The
coupling sealing surfaces must point towards the right.

Maintenance
The sealing surfaces must be clean and must be replaced if
they become damaged. In the case of coupling heads with
integrated fi lter, the fi lter inserts are to be cleaned regularly (at
least once a year).
Inspection
