Boom / Bucket angle calibration
-
MCU get sensing signal from boom angle
and bell crank angle and calculate bucket
cylinder stroke and boom link position an-
gle from ground real time basis.
-
Boom angle position and bucket cylinder
stroke is set by detent setting switch on
monitor.
-
Individual setting position is done by lever
(detent, release operation).
-
Angle sensor calibration is basically car-
ried out before delivery of the machine.
When angle sensor is replaced or actual
value is different compared to setting val-
ue, this function can be done.
-
The calibration must be carried out as fol-
lows :
a.
Lower the boom at maximum low po-
sition and press NEXT button or (bucket must be max tilting position).
b.
Raise boom at maximum high position and press NEXT button (or ).
c.
Position boom at -5° and press NEXT button (or ).
d.
Retract bucket cylinder length (to minimum position) at -5° boom position and press
NEXT button (or ).
e.
Extend bucket cylinder length (to maximum position) at -5° boom position and press
NEXT button (or ).
f.
In case above steps are carried normally, "Calibration is done" message is shown. Then
angle sensor calibration is finished.
