iCON grade, Calibrating the System
1. Position the blade in a horizontally flat position. Use two concrete
blocks (or equivalent) placing one underneath each side of the blade.
Lower the blade such that it rests on the two blocks. Mark the posi-
tion of the blade on the two blocks with spray paint (or equivalent).
Now change the setting such that the sensor value in the "< >" says
zero.
2. Turn the machine 180 degrees (reversing direction) and put the blade
back to the same position on the two blocks. Note down the
sensor
value
in the "< >".
Subtract the
sensor value by half
and add the result to the Blade Offset
value. If the
sensor value is negative
, then subtract this value from the
Blade Offset value.
Step 9:
BLADE CUT-OFF
Together with mainfall cut-off, this setting controls the "noise" and vibra-
tion inherently present on heavy machinery and for handling brief accel-
erations/decelerations of the machine.
There are two blade cut-off settings, blade threshold and blade timeout.
These are located in the Calibration menu.
Recommended values for the Blade Threshold is 1.5% and for the Blade
Timeout 600 ms.
Only a qualified service technician should modify these values.
Step 10:
MAINFALL OFFSET
To calibrate the mainfall sensor complete the following steps:
1. Park the machine on level ground.
2. Put the frame in a straight position (that is, with the gooseneck not
articulated).
3. Make sure that the front wheels of the grader are vertical.
4. Enter the menu on the control panel. Go to the
Calibrate -> Mainfall
offset
menu option.
5. Adjust the mainfall offset until the number in
<>
becomes
0
.
If it isn't possible to park the grader at a completely level surface then a
second calibration method can be used:
1. Park the machine on solid ground such as asphalt or concrete.
2. Mark the position of the front and rear wheels with marking spray
paint or equivalent. This is position 1 on picture below.
3. Enter the menu on the control panel. Go to the
Calibrate -> Mainfall
offset
menu option.
4. Write down the sensor value shown in the <>, remember to note the
sign also.
5. Turn the machine around and place the front wheels were the rear
wheels were and the rear wheels on the front wheels mark this is
position 2 on picture below.
6. Enter the menu on the control panel. Go to the
Calibrate -> Mainfall
offset
menu option.
