Menu 9 – Compensation
The purpose of the compensation system is to ensure during boom down operations the hook load
remains accurate. It is not uncommon, when boom down operations begin, to see a slight dip in the
hook load. But if properly adjusted, the load compensation system will more accurately display the load.
1. To get into the compensation menu press the
09 Compensation
button. This will take you into
a new window that looks like this:
There are
Next
and
Previous
menus which allow the adjustment for the slow and fast angle
rate.
2. It is recommended to adjust the slow offset first. To adjust the compensation, extend the boom
approximately halfway out using a load of say 2000 pounds and lowering the boom at a slow
rate. If the displayed load diminishes or disappears during this operation, press
Edit
to enter the
menu allowing you to increase of decrease the amount of offset. This adjustment must be done
while the boom is in motion. Press the
Decrease
button to cause the offset number to display
negative. Press the
Increase
button to cause the number to become a positive number.
3. Once the load is satisfactory on the slow offset, press the
Exit
button to return to the previous
menu. Press the
Next
button to access the fast offset. Use the same procedure as the slow
offset, except boom down more quickly. When finished, press the
Exit
button on the lower right
to return to the main menu.
