66 26.11.07 1 689 979 924N8. Measuring optionsBrake tests can be performed in the automatic mode of operation(„Automatik“) or in the manual mode („Hand“).8.1 Automatic mode („Automatik“) Press the push-button „Automatik“ A (12), indicator light „Automatik“ (8) lights up orpress the keys A (68) and e (59) at the same time, indicator light „Automatik“ (8) lights up.The drive motors will be activated automatically when the testvehicle is driven into the roller sets.i During running-up of the drive motors, no brake test andinput by the remote control is possible.8.2 Manual mode („Hand“) Press the key „AUS“ c (52), Press the key m (66). press the keys l (50) and e (59)at the same time, theleft-hand roller set is activated.Wait until the roller set has run up. gleichzeitig Tasten r (51) und e (59) drücken, derrechte Rollensatz wird eingeschaltet.i If the right-hand and left-hand side are tested separately inthe manual mode „Hand“, an allocation of the brake pres-sures p m /p z to the braking forces is not possible.8.3 Brake test sequenceThe brake test sequence is different, depending on whether theevaluation is carried out manually or by the test stand (automati-cally).8.3.1 Brake test with manual evaluationMake sure that there are no persons in the teststand area!Danger to life for any persons in the test roller area!Observe the regulations for the prevention of acci-dents!In case of danger, press the„EMERGENCY STOP switch“ (13)!! Drive the vehicle slowly into the roller sets.Orient yourself by the guiding mark (24).In doing so, it is guaranteed that- the wheels are approximately in the middle of the test rollers,- that the vehicle is in alignment,- that the tire shoulder is free and does not touch the coversheets.Select the mode of operation „Automatik“ or „Hand“.Hold tight the steering wheel after the drive motors were activa-ted.If the vehicle does not stand at right angles to the teststand, it will drift to the side!Danger to life for any persons in the test roller area!In case of danger, press the„EMERGENCY STOP switch“ (13)!Level out the vehicle by the steering.If the axle actuated by the parking brake is not to be tested, avoida lateral drift of the vehicle by applying the parking brake.i Secure the wheels outside the test stand by wheel chocksif you test the parking brake.i Wet brakes falsify the measuring values.Brake the brakes dry with medium braking force!Slowly increase the braking force.The display unit shows the braking forces of the left-hand andright-hand wheel brakes. If the braking force difference exceeds25 %, the indicator light „Braking force difference! (1) lights up.The braking force difference of 25 % is factory-set. Our customerservice can set a different value.Special featuresThe BT 6xx has 2 combination brake force displays with thedisplay ranges 0–8 kN and 0–40 kN.If the display is in the range 0–8 kN, the measuring range light „0–8kN“ (2.1.1) lights up.As soon as the left-hand or right-hand braking force exceeds 8 kN,there will be an automatic change-over to the display range 0–40kN and the light goes out.If the slip limit is reached, the drive motors of the roller sets aredeactivated automatically. The indicator light „Slip deactivationRH/LH“ (3) indicates the side having caused the slip.If the brake test braking force is so low that the automatic slipdeactivation is not actuated, Press the key S (58).The driving motors will be deactivated. The brake force course isstored.! Drive off the vehicle from the test stand only in forwarddirection and when the test rollers are running!Now, the next axle or brake system can be tested. |
