2.5.1.1.1 ACCELERATOR SENSOR OUTPUT SIGNALS
The accelerator output signal can be measured at connector 1X10.
Pin arrangement 1X10
1=(15 V)
2=(output signal)
3=(-)
4=(1S12 direction of travel)
5=(+ U
B
direction of travel)
6=Enable
The output signal can vary within the following range:
Neutral Position Max. Reverse Max. Forward
Output signal
measured (1X10/2-3) 7.5 V 11.25±0.65 V 3.75±0.65 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.
Reverse Forward
Neutral position: 7.5 V 7.5 V
Contactor makes: 8.2 V 6.8 V
Clocking starts: 8.4 V 6.6 V
End-point signal approx.: 11.25 V 3.75 V
Contactor breaks: 8.0 V 7.0 V
2.5.1.1.2 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.
