iCON grade, Calibrating the System
If the hydraulic system is an open-center system the idle speed must be
set to zero.
For Sideshift, the idle speed (left and right) must be set to zero.
Step 4:
MIN SPEED
The Min Speed is the fine precision control of the blade.
Precise meas-
urement of this setting is crucial for maximum performance
. Use of
a tape measure and stopwatch are highly recommended for this setting.
Adjust the min speed for each valve (left and right side for Sideshift) in
both directions (up / down or left / right for Sideshift) to the speed indi-
cated below. Verify the solution by pressing the
10s
button in the
Min
Speed calibration menu
. A tape measure is recommended.
For Lift, both left and right side:
Adjust this setting so that the blade moves 4 cm in 10 seconds measured
at the edge of the blade. Verify for both up and down motion. If one
setting results in too much movement and one setting lower is too little
movement, then select the slower option.
Step 5:
SYMMETRY
This compensates for the additional force required to lift the blade versus
lowering the blade. It is important for the system to provide identical
motion of the blade both upwards and downwards. Using a tape
measure, adjust the Symmetry value so that the blade returns to the
same position. Repeat for Lift, Tilt, and Sideshift.
Machine performance will vary depending on material type, weight,
and the load on the blade. If the machine appears "too slow" or
"too fast", DO NOT adjust any of the calibration settings. Perfor-
mance adjustments are compensated with the Gain settings for the
sensors used. Adjusting the Calibration values will not improve
machine performance!
Step 6:
CROSS-COUPLING
(X-COUPLING)
This setting is used for compensating for the motion of one side of the
blade to the motion on the other. The result is that the use of positioning
sensor with a slope sensor will react instantly on the slope side to any
vertical movement from the distance sensor. The recommended setting
is 35%.
If the machine fails to calibrate correctly for Min Speed and Gain, then the
Cross-Coupling should be set to Zero.
Step 7:
Auto/Manual
Switch Setup
Refer to chapter "3.9 Configuration of Auto / Manual Switches".
Step 8:
BLADE OFFSET
While every attempt should be made to weld or bolt on the cross-slope
sensor as true to horizontally flat as possible, this is often very difficult
to accomplish. To compensate for what error may remain, the blade
offset setting will correct for the difference between the actual and true
sensor angles.
