Safety Devices
- The lockable main switch can also be used as an emergency off-switch
- automatic button with pre-selection for a manual or an automatic start of the test stand
-
Automatic start of the test stand:
In the automatic operating mode, both sensor rolls must be
pushed down at the same time within 3 seconds, then the test stand starts with a time delay of
about 5 seconds. The test stand can be set in such a way that both rollers start at the same time
or consecutively with a time delay.
-
Automatic start-up monitoring:
The test stand detects wheels which turn with difficulty or which
are locked up and automatically shuts down after the test has been started. After about 5
seconds the test stand attempts to start again. The reason for wheels which rotate with difficulty
or are locked up can be an engaged gear, a pressed brake pedal, an actuated parking brake, an
all-wheel drive system or a defect on the brakes, bearings or else. If the test stand shuts down
again, the vehicle must be driven out of the set of rollers and the reason for the difficulty of
rotation must be inspected.
-
Automatic standby-mode switch-off:
If the test stand has started and no braking test has been
carried out for a longer period of time, the test stand automatically switches to manual mode.
-
Automatic slip switch-off:
The sensor rolls monitor the difference in the speed of rotation
between the wheels and the drive rollers. If a certain slip value is exceeded, the test stand
automatically shuts down. The slip limit is adjustable. The parameterization of this value is only to
be carried out by the authorized service personnel.
- The test stand also automatically shuts down if the load on the driving engines becomes too high
and the input speed drops under the pre-set slip value.
-
Automatic restart:
In the automatic mode, the test stand is switched on again each time after
the sensor rolls have been pushed down for about 5 seconds.
-
Automatic shut-down after the vehicle left the test stand:
If the vehicle is driven out of the
test stand and the sensor rolls move upwards, the test stand automatically shuts down.
-
Automatic auxiliary drive-off system:
If the test stand is driven by the drive wheels of the
vehicle and hence the test speed of the test stand is exceeded, the electric motors of the test
stand are automatically engaged. This prevents the rollers of the test stand from over-speeding
and makes it easier for the vehicle to be driven out. Additional power of the motors is provided in
all modes of operation, as long as the test stand is active and is connected to the power supply.

Operating Elements
7.2.1
Control Box
reset switch, to delete the
errors of the
frequency converter
main switch at the side
of the housing
Option:
direction of rotation and
measurement
reversal, rollers left
forwards / off / backwards
selector switch for test mode
MOTORCYCLE-PASSENGER
CAR-TRUCK
automatic button
Option:
direction of rotation and
measurement
reversal, rollers right
forwards / off / backwards
Option:
direction of rotation and measurement reversal, both rollers rotate in the same or in
opposite directions and single wheel changeover, operation at the control box
- By means of this option, each side of the drive rollers can be rotated forwards and backwards or
even turned off. By this means, not only the direction of rotation but also the direction of
measurement will be reversed automatically.
- The extended option
“automatic all-wheel drive detection”
is activated if both switches are in
middle position.
Option:
Selector switch for preselecting the vehicle, testing a motorcycle, a passenger car or a truck
