How to Calibrate the Load Cell
1 Release the parking brake.
2 For machine on wheels: To enter the calibration
mode, press the function key "a" on the display
while holding the bypass key in the "activation"
position for 5 seconds (ensure that the yellow
LEDs blink).
3 Press the function key "a" on the display to
start acquiring data (ensure that the green
LEDs blink).
4 Bring the machine with no accessory fitted to a
stable position (boom raised and retracted).
5 Press the function key "a" to acquire the first
datum (ensure that the red LEDs blink).
6 Install the forks, load a weight of 5500 lbs /
2500 kg, bring the forks as close as possible to
the ground and start extending the boom slowly
to discharge the weight from the rear axle (the
rear wheels will slightly lift off the ground).
7 Press the function key "a" to acquire the
second datum (ensure that the yellow LEDs
blink).
8 Press the function key to store the acquired
data in the EEPROM memory. If during data
acquisition at least one datum is out of the
valid range, the 2 red LEDs will illuminate with
a solid light. If the operator chooses to store
the data acquired during last calibration, the
out-of-range values will not replace the values
currently used by the system.
NOTICE
After the first calibration, the
machine must be turned off. This
procedure is not needed for any
subsequent calibrations.
