9.1.1 Signal Measurement at the
Drive Controller (SEVCON)
5. Cabling between accelerator potentiometer and drive controller okay?
Voltage measurement:
Green at A6-X51:8 (approx. 8.6V)
Red at A6-X51:9 (0-5V depending on potentiometer position)
Yellow at A6-X51:3 (approx. 0V)
Measured to battery minus
Resistance measurement (with machine switched off and
potentiometer disconnected):
Between green and red: approx. 5.7 k
W
Reducing to approx. 1.8 k
W
upon actuation
Between yellow and red: approx. 1.8 k
W
Increasing to approx. 5.7 k
W
upon actuation
Between yellow and green: approx. 4 k
W
Unchanged upon actuation
Caution: The potentiometer has a nominal value of 4 k
W 
20%. This means:
Due to the 20% tolerance, values may vary between 3.2 k
W
and 4.8 k
W
.
Depending on these tolerances, the measured values may increase or reduce
by up to 0.8 k
