Operations

3.6Imbalance Display (Optional)

!Imbalance display

The imbalance display will show the difference between the right-hand and left- hand brake force in percentage (%). The imbalance display will be activated when a pre-set total brake force is reached.

The brake force difference should not exceed the legal permissable value.

!Testing in the large measuring range

If a vehicle is tested using the large measurement range (measurement range switch-over on the remote control or on the test stand) it can happen that the necessary trigger value to activate the imbalance display is not reached because the attained brake forces were not high enough. In this case, there will be no imbalance display.

3.7Special Features on Test Stands with MB Mode

Selection of the operating mode

Test stands with MB-Mode are equipped with an operational selector switch making it possible to switch between:

•"Automatic" : the rollers will start up automatically after the switch-on time delay.and

• "Manual" : the rollers are started one after the other manually by using the remote control. Observe the green lamp which indicates in which operational mode the test stand is.

The green lamp will extinguish if the pit safety system is triggered.

Switching on the unoccupied test stand

The "Automatic" operational mode is started by turning on the main switch while the test stand is unoccupied. Use the selector switch to switch to "Manual" operation.

Switching on the occupied test stand

The "Manual" operational mode is started by turning on the main switch while the test stand is occupied. The test stand can only be switched to "Automatic" operational mode when it is unoccupied.

Acknowledging malfunctions

Test stands with MB-Mode are also equipped with a malfunction button. If problems occur during operation, the malfunction lamp will light up. Certain problems can be acknowledged by pressing the malfunction button. (see defect codes).

If the trouble occurs while the test stand is occupied, it immediately switches to "Manual" operation.
