4.4.2 Steering potentiometer
1. Specification of steering potentiometer
Resistance limitation: 0KΩ-5KΩ
Steering angle: 0°-360°
Voltage: 12V
2. Adjustment
a) Install the potentiometer on truck body, make steering wheels on zero
degree(straight traveling direction), adjust potentiometer to make output resistance value
be about 2.5 KΩ, if there is deviation, the output resistance must be between 0 KΩ and 5
KΩ when locating on 90
0
, -90
0
position.
b) Connect PC machine with controller connector.
c) If electric potentiometer installs correctly, the output voltage value will be changed
with hand wheel’s turning.
d) Enter STEERING SENSOR CALIBRATION menu.
e) Select ANTICLOCK parameter, turn hand wheel left until minimum steering value
displays, save it.
f) Enter CLOCK menu.
g) Turn hand wheel right, until maximum steering value displays, save it.
h) Enter MIDDLE menu.
i) Turn the steering wheel left and right until zero value displays (straight traveling
direction), save it.
j) Quit the menu.
