9.2 SETTING THE ACCELERATOR PETAL
Before further setting of the drive rheostat use a voltmeter to measure at the drive
control unit between X51 Pin 3 and Pin 9.
When the accelerator pedal is not pressed down, the voltage has to amount to
U
≈
0 V and increase continuously up to U
≈
6.5 V as the pedal is pressed down to
stop. In order to guarantee a perfect operation, the minimum voltage attained when
pressing down the pedal has to be U = 4.5 V.
After the pedal has attained its limit position, the drive rheostat must not positioned
at a stop. A clearance of 2mm is required between the final position of the accelerator
and the rheostat stop (check at the adjusting lever of the ‘R1’ rheostat if required).
If the stop position of the drive rheostat has already been attained with the
accelerator
pedal, the drive rheostat may be turned in its oblong holes.
Irrespective of the pedal position, a voltage of approx.
U
≈
10,5 V
applies between X51 Pin 3 and Pin 8.
