DENOMINATION
INTERVENTIONS
Parking brake distributor
Parking brake distributor
(with control position)
Actuate the parking brake distributor till it snaps; the manometer
inserted on the control plug must mark the pressure discharge down
to 0 bar in 1 sec.
Simultaneously at the automatic coupling joint duct, the manometer
must show a pressure of 7.5 bar.
Quick discharge valve
Check functionality and seal.
Actuate the parking brake distributor, verify that the compressed air
is quickly discharged from the circuit.
Trailer braking triple-control
servodistributor
Fill-in the tank. Connect a manometer to the automatic coupling
head, and one to the moderate coupling head.
At a pressure of 1 bar, sent by Duplex distributor, in the moderate
coupling head a pressure from 0.8 to 1.5 bar must correspond. Carry
out a total braking (unmoving vehicle).
At the coupling head, the required braking pressure must be
available or a pressure decreased by 0.5 bar. Insert the parking brake;
at the moderate coupling head, the pressure must remain
unchanged or decreased by 0.5 bar.
Coupling heads
Check that there are no dirt or damages in coupling guides.
At the end of the coupling, actuate the brake pedal and check seal
and stability between coupling heads by inserting air at 7.5 bar.
Check that there is no air leakage from coupling gaskets.
Hydraulic or pneumatic pressure
control plugs
Make sure that protection plugs are inserted, check that they are
completely screwed.
Membrane cylinder
Check securing, integrity and seal.
The drain hole must be downwards oriented and must not be
clogged.
Combined cylinder
Check securing, integrity and seal.
The drain hole must be downwards oriented and must not be
clogged.
