9. ADJUSTING LOAD DISPLAY

-Actual boom length must agree with the length step (LS) on the hand terminal display-.
Hoist a known test load. The test load shall be = or > 75% of the rated capacity. Refer to the
crane load chart. Hoist the load just above the ground and read the load display on the hand
terminal. Compare the displayed load with the actual load. Calculate the difference between
The terminal display indicates >C-LOAD I= n: <. or >C-LOAD x= n: <
Note: n = previously entered correction factor. x= a number between 1 and 7.
A load correction value can be entered and stored for the following boom angles(degree).
These correspond on the hand terminal display to >C-LOAD 1,............C-LOAD 7<.
If the boom is positioned between two of those angles during the initial start of the >V< function
Enter the calculated or estimated load correction factor in (% x 100) for the initial starting angle.
Note: If the address has already a data you must either subtract or add your calculated correction
factor. In example >C-LOAD I= -200< -- with a calculated correction factor of -- 4% enter
>C-LOAD I= -600<. Note: The correction value is limited to +/- 1000 = +/- 10%.
The program extrapolates the entry and writes the calculated values into the next stored angles
