MG510R Calibration 25 W450256 Rev A 06/07
Menu 09 - Compensation
This menu is used to enter data to compensate for fluctuating loads.
Loads can change dramatically when booming down because of fluctuating pressures in the base
side of the boom hoist cylinder. The rod side pressure transducer constantly monitors these
pressure changes on the base and rod side of the boom hoist cylinder and sends its signals to the
computer for processing. This signal calculates a correction for the fluctuations that are caused in
the base side pressure of the boom hoist cylinder being used to measure the load. This routine will
allow for adjustment of these pressure fluctuations.
TEST
SET
Press the key adjacent to either “Menu Up” or “Menu Down” until “09 Compensation” appears in the
information window at the right.
Press the key adjacent to “09 Compensation” to enter the routine.
To accomplish this testing, the boom should be half extended with a medium hook load of 2000 or
3000 lbs.
Set the boom angle above 60° and raise the load. 1.
Boom down at normal speed. Note the hook load during decent. If the load goes to “0” or 2.
drops and stays down, adjusting the compensation should bring it back up to the proper
reading during the boom down process.
Two compensation modes are allowed; “Slow Rate” and “Fast Rate”. The actual rate of the boom is
displayed while in this routine.
Press the key adjacent to “Edit” to enter the routine. Use the keys adjacent to “Next” and 3.
“Previous” to select desired compensations.
TEST
SET
Select the rate by pressing the key adjacent to “Edit” and adjust the offset value by pressing 4.
the key adjacent to “Increase” and “Decrease”. To see the effect, lower the boom. If the effect
is too small, increase the compensation.
TEST
SET
Note: It is customary to leave the slow rate compensation as “0”, or a very small number and adjust
the fast rate compensation to counter the booming down effect.
When you have finished, press the key adjacent to “Exit”. Press the key adjacent to “Next” or
“Previous” to adjust the fast rate compensation value. Repeat steps 1 and 2.
Note: Compensation is activated only when booming down.
