10.2.1 Test sequence for towing vehicle
Testing axle 1
Drive the axle 1 into the roller set.
Wait for running up of driving motors.
Press the key
a
(64).
Slowly increase the braking force of the SBS.
The run-out is determined automatically, if a braking force of >
3,000 N *) is kept constant over a time period of > 7 seconds
(approximately 1 wheel revolution).
Increase the braking force until the automatic slip deactivation
reacts. If there is no slip deactivation, press the key
S
(58) on the
remote control unit. By this, the maximally attained braking force
is taken over into the computer.
Drive the vehicle axle 1 out of the roller set.
Disconnect the measuring line for the pressurek pz1 on the brake
cylinder of axle 1 and connect it to axle 2 (not necessary, if radio
pressure sensors are used).
!
In order to determine the pressure value by extrapola-
tion based on the guideline governing the official vehic-
le inspection, according to § 29 STVZO dated
29.04.1993, the following procedure must be follo-
wed.
Definition of of the input pressure of the sensors P
zn
by measns of the LCD display
- determine the roller resistance, then press the button
U
(62) in order to change to the display mode of
pressure sensors P
zn
- gradually increase the brake force up to the input
pressure P
zn
and confirm by pressing
E
(60)
Definition of of the input pressure of the sensors P
zn
without an LCD display
- Activate the drive motors and wait until the automatic
mode inidcation lamp stops to flash.
- gradually increase the brake force until the fingers of
the analogue dials start to move.
- confirm the value by pressing
E
(60)
Testing axle 2
Drive axle 2 into the roller set.
Wait for running up of driving motors.
Press the key
a
(64) or
Press the key

2
and
E
(60).
Slowly increase the braking force of the SBS.
The run-out is determined automatically, if a braking force of >
3,000 N *) is kept constant over a time period of > 7 seconds
(approximately 1 wheel revolution).
Increase the braking force until the automatic slip deactivation
reacts. If there is no slip deactivation, press the key
S
(58) on the
remote control unit. By this, the maximally attained braking force
is taken over into the computer.
According to the specifications, the SBS of axle 2 belongs to the
AUBS 1.
Press the keys „
HBA
“ (54)
1
(9) „
HBA
“ (54) and „
2
“ (61)
„
BBA
“ (53) and „
ENTER
“ (60).
Test the parking braking system PBS of axle 2.
Wait for running up of driving motors.
Press the key
h
(55).
Increase the braking force of the PBS slowly until the automatic
slip deactivation reacts. If there is no slip deactivation, press the
key
S
(58) on the remote control unit. By this, the maximally
attained braking force is taken over into the computer.
Drive axle 2 out of the roller set.
i
In the example, there is only one test connection pz for axle
2 and 3. The measuring line must not be disconnected!
Testing axle 3
Drive axle 3 into the roller set.
Wait for running up of driving motors.
Press the keys
a
(64)
3
and
E
(60) or
press the key
E
(60).
Test the service braking system SBS of axle 3.
Press the key
F
(53).
Slowly increase the braking force of the SBS.
The run-out is determined automatically, if a braking force of >
3,000 N *) is kept constant over a time period of > 7 seconds
(approximately 1 wheel revolution).
Increase the braking force until the automatic slip deactivation
reacts. If there is no slip deactivation, press the key
S
(58) on the
remote control unit. By this, the maximally attained braking force
is taken over into the computer.
Test the parking braking system PBS of axle 3.
Wait for running up of driving motors.
Press the keys
h
(55).
Increase the braking force of the PBS slowly until the automatic
slip deactivation reacts. If there is no slip deactivation, press the
key
S
(58) on the remote control unit. By this, the maximally
attained braking force is taken over into the computer.
The vehicle may „climb“!
If the vehicle „climbs“ out of the roller set,
Danger to life
for any persons in the test roller area!
453258/1P
In case of danger, press the
„EMERGENCY STOP switch“ (13)!
