WABCO TAILGUARD - Braking System and TailGUARD Operation Safety

2.2 Summary of the safety instructions from the chapters
Observe the following safety instructions for interventions in the braking system:
 Observethespecicationsofthevehiclemanufacturer.
 Deactivationwhenthesupplypressureistoolow:Switchthesystemoffif
thevehicle'ssupplypressureistoolow.
 Onlyintervenewiththebrakingsystemifyouhavesufcientknowledgeof
thebrakingsystemandknowandcantakeresponsibilityfortheeffectof
youractionsandalltheirconsequences.
 Thebrakingsystemisunderpressure.Beforeinterveningwiththebraking
system,makesureallreservoirsandlinesarepressureless.
 Withbrakinginterventionsvia separately installed valves,thefrontaxle
mustnotbebraked.Makesurethatthevehicle'sfrontaxlecanNOTbe
brakedbythesystem.Brakinginterventionmustonlyoccurviatherear
axle(s).
To avoid any accidents, observe the following safety instructions for vehicles with braking intervention
through TailGUARD:
 Becausethestoppingdistancebecomeslongerwithheavilyladenvehicles
-inparticularwhenitisequippedwithEBS-thesettings(parameter
setting/pressurelimitingvalve)mustenablesufcientdecelerationforthe
fullyladenvehicle.
 Notepulsedbrakingwhenreversingtoofast:
 TailGUARDcanassistonlywithreversingspeedsbelowmax.9km/h.
 TailGUARDwilltriggershortbrakepulseswhenacriticalspeedis
reachedtoalertthedriver.
 Ifthedriveracceleratesfurther,TailGUARDdeactivatesitselfand
outputsafaultmessage.
 InthecaseofEBSvehicleswithbrakeinterventionvia separately
installed valves, ABSfunctionsarenotavailableduringTailGUARD
braking.EvenatthelowspeedrangeatwhichTailGUARDisactive,the
wheelsmightlockonslipperysurfaces.
 Speedsignalfaultsduetoincorrectorunprofessionalconnectioncan
signicantlyimpairvehiclesafety.
 Vehicles with a prepared interface for TailGUARD: TailGUARD may not
brakeifthevehicle’sEBSsystemhasafault.
