13. Performance test and checking for leaks
Venting pressure
Pressure regulator must vent at approx. 8.1 bar (8 bars on LCD display).
In event of discrepancies, adjust pressure regulator on air tank.
Text-module
Tightness against leaks
Weekly checks with engine off:
Pressure drop with full system may not exceed 0.5 bar in 2 hours.
Text-module
Bullet-List
Check trailer advance-braking control system.
●
Fill air compressor until pressure regulator vents
●
With footbrake not actuated and handbrake released, yellow coupling head must be unpressurised.
●
After 20 mm footbrake pedal travel there must be pressure of 0.5 - 1 bar acting on yellow coupling
head.
In event of discrepancies, adjust solenoid switch (S005 / S006) on footbrake pedal
(see Favorit 700 Workshop Manual, Chapter 1070 Reg. F).
Text-module
Bullet-List
Check trailer control line (single-line system).
●
With brake released, pressure at black coupling head must be 5.1 - 5.5.
●
When footbrake or handbrake is actuated, pressure must drop to 0 bar.
Setting at trailer control valve (single-line system)
Text-module
Bullet-List
Setting handbrake
●
Set such that there is no pressure at yellow coupling head with handbrake released.
●
With 50% handbrake handle travel, pressure should rise to 70 - 7.8 bar.
Setting at linkage between trailer control valve (dual-line system) and brake cylinder.
