WINDOW 6 ANALOGUE SIGNALS
Window 6 displays the analogue values for the travel and RPM control.
Voltage behind relay contact K1
in the LHC module
Power supply
Potentiometer actual
value in %
TEST CONDITIONS FOR MEASURING ANALOGUE VALUES VR AND VS
- Accelerator pedal in neutral position
- Brake pedal released
- Ignition on
- Battery voltage > 11.3 V
vr: Voltage behind relay contact K1 in the LHC module
The voltage should be approx. battery voltage.
vs Power supply 10 V
The voltage is provided by the electronic controller voltage regulator. The specified value is 9,500
- 10,500 mV and it is indicated under vs.
If the value is out of range, the controller assembly must be replaced.
p1: Potentiometer actual value in %
After the zero calibration of potentiometer 1B2 (see window 8), -100 % to +100 % should be obtained
for maximum forward and reverse pedal stroke.
NOTE: The maximum values for forward and reverse should be set with the respective pedal
stop screws.
