Electrical System
c. Boom Angle Sensor Installation
1. Install the sensor assembly to the sensor seat and
tighten both bolts.
2. Install the rod end to the sensor arm and tighten nut.
3. Measure and set rod length to 256 mm (10 in) if
needed.
4. Plug the electrical connector into the sensor
assembly.
5. Connect the battery negative (-) cable to the battery
negative (-) terminal.
6. Close and secure the engine cover.
d. Boom Angle Sensor Adjustment
1. Access Level 2 can be reached by pressing buttons
C
and
OK
at the same time.
2. Access level 2 consists of the following menu items:
• Anti-theft device
• Software-version
• Learning
3. The following submenus can be found in the
Learning Menu:
• Boom
• Vehicle Speed
4. After choosing "Boom" the analog values of the
boom angle sensor for the upper and lower limit
positions get determined and taken over.
The range detection of the analog values for the
boom must be performed for the boom angle sensor
in order to allow a precise calculation of the boom
angle.
Firstly, the upper analog value is learned. When the
boom is moved upwards (joystick Y-axis moved to
the back) one can see the analog value gets higher.
At the upper limit position of the boom the value gets
confirmed by pressing the
OK
button and the
learning of the lower limit position can be started.
When the boom is moved downwards (joystick Y-axis
moved to the front) the value decreases. At the lower
limit position the value needs to be confirmed with
the
OK
button and one comes back to the Learning
menu.
Conditions for the value range:
• If the lower value is outside the range of 70-330,
a value of 100 is taken over.
• If the upper value is outside the range of 550-
850, a value of 800 is taken over.
5. If either the lower value (100) or the upper value
(800) is shown, the boom angle rod may need
adjusted.
