ACCELERATOR SENSOR OUTPUT SIGNALS

The accelerator output signal can be measured at connector 1X10.
The output signal can vary within the following range:
Output signal
measured (1X10/2-3) 7.5 V
The control range for the accelerator sensor is between 7.5 V and 11.25 V for reverse travel and between
7.5 V and 3.75 V for forward travel.
The following voltages are important for the control range when checking the traction control for proper
function.

ADJUSTMENT OF THE NEUTRAL POSITION

After loosening both locknuts, adjust the connecting rod from the pedals to the accelerator sensor so that
the travel required to actuate the accelerator sensor microswitch is equal in both directions of travel.
