3.4Preparations for a Brake Test

The procedures described here are for normal operation of 4 wheel drive test stands. (4 wheel drive switch to position "0"). There is a seperate description available for the 4 wheel drive test. (See Tele-BPS II + RCF 30 operating manual).

If the test stand is equipped with an internal scale no weight may burden the roller set when the test stand is switched on. Otherwise the weighing electronic will store this switch on weight as an Offset value and the measurement will be distorted.

!Enable main switch

The needle of the display will complete an offset balance and return to zero.

!Press POWER ON key

Press POWER ON button or the '*' key on the remote control.

The white POWER ON lamp should now be lit up. The needles will again adjust and return to zero. The test stand is now ready for operation!!

On test stands without a PC-console but equipped with a DIN A4-printer which is offline or defective, the message "Printer defective (ONLINE?)" will appear after switch-on. If the test should be carried out without the printer, the printer can be de-activated by pressing the Power On button again.

!Select the measuring range (optional)

If the test stand is equipped with a manual measurement range button, use it to select the desired measurement range. The integrated green lamp will light up when the large measurement range is selected.

!Conduct a single-wheel test (optional)

Test stand which are not equipped with a remote control have a single wheel switch which facilitates single wheel testing. Depending on the test stand version the Power-On key must be pressed after a single wheel test.

The rollers will start up automatically after a single wheel test when the switch has been re-set to the 0 position.

3.5Running a Brake Test

The manufacturer does not accept any liability claims for damage to low lying vehicle parts.

Drive first axle to be tested onto the roller set switch into idle. After the delayed start-up, the motors will be started individually. Should the motors switch off again immediately, the start-up monitor has been triggered to protect your vehicle and/or its tires against damage. One or both wheels may be jammed (seized bearings, jammed brake pads, etc.).
