en 46 | BSA 43xx | Operation
R
If the vehicle runs off the set of rollers during the
brake test, causing the slip rollers to move upwards,
the drive rollers are automatically deactivated.
R
If the braking force exceeds the frictional force
between the wheel and the test rollers, the wheel
starts to slip (lock up). The drive rollers of the
BSA 43xx are automatically deactivated to avoid
damaging the tires.
4.6.3 Notes on brake testing for four-wheel drive
vehicles
R
All-wheel measurements are intended for vehicles
with permanent four-wheel drive.
R
The left and right test rollers are operated in
opposite directions to guard against overloading
of the vehicle limited slip differential.
R
The braking forces are measured on the side turning
forwards.
!
Also heed the test instructions in the 4WD vehicle
operating manual.
4.6.4

Notes on motorcycle brake testing

!
Motorcycle brake testing on the car brake tester is
only performed on the left roller and only in manual
mode.
¶
Use the motorcycle cover on the left side of the
rollers.
¶
Use the standard cover (clipped in or hinged) on the
right side of the rollers.
!
For the „Motorcycle" test routine, the analogue dis-
play must be equipped with LCD.

Notes on suspension tester

SDL 43x
R
Refer to the product description for setting the zero
point of the axle load scales.
R
The left and right sides of the chassis are tested
separately.
R
Chassis testing cannot be performed until both the
wheels of one axle are positioned on the shaker
plates.
R
If the vehicle runs off the set of shaker plates during
the chassis test, the drive motors are automatically
deactivated.
¶
Apply the brake during testing.

Notes on noise simulator

R
The noise simulation function is only ever to be
activated as briefly as possible.
R
Heavy vehicles and low frequencies exert the
greatest load on the device.
R
The noise simulation function is not to be activated
for more than 20 minutes per hour, taking care to
ensure even distribution of the operating times and
intervals (ideally: 3 minutes operation, 6 minutes
interval).
R
If a motor overheating smell becomes apparent,
terminate the application immediately for at least
15 minutes. To permit further operation of the
cooling fans, the system should not however be
switched off at the master switch.
4.6.7

Notes on side slip tester

¶
Drive both axles at a constant speed (max. 15 km/h)
over the side slip tester, taking care to keep the
vehicle straight.
4.7

Selecting test routine

i
Test routines contain test steps with fixed and con-
figurable parameters (e.g. peak value display time).
After switching on the BSA 43xx, the test routine P1
(brake test) or L1 (test lane) is selected automatically.
If required, additional test routines can be configured
by Service personnel.
i
If only one test routine is available for a particular
tester, the corresponding test routine is selected
automatically together with the tester.
i
If several test routines are available for a particular
tester, a list of the test routines available is
presented after selecting the tester.
