Setup - Load Cell Board (ECM3) Calibration
After having replaced the master board (ECM1) or the load
cell board (ECM3) or having replaced the load cell sensor
it's necessary to calibrate the “0” of the load cell system, by
this procedure the calibration parameters relevant to the
load cell sensor installed will be memorized on the ECM1.
Being possible difference between one load cell sensor
and another it's necessary to calibrate ECM1 with the load
cell sensor installed on the machine and not with another.
The load sensor system reset must be done with the bas-
ket removed.
The reset the load sensor system consist into saving the
value “0”, done without the basket, here follows the cali-
bration procedure:
1.
Turn ON the main key and stabilize the machine.
Stay out from the basket with remote control on
hands.
2.
Press button n.6 (SERVICE) and then press but-
ton n.7 (SETUP).
3.
Press button n.5 (PASSWORD). The display will
ask for the password.
4.
Inserting password 6138 the display will confirm
with “OK”.
5.
Press button n.9 (EXIT) and then button n.7
(LOAD SENS), the display will than visualize the
page here below:
6.
With the basket removed, press button n.3
(CALIB) and verify that display indicates “OK”. In
case of the basket is still loaded on its support
this page will display “NOT READY” instead of
“READY” and reset will not be possible.
7.
Press button n.9 (ESC) and then turn OFF the
main key.
8.
Turn ON again the main key and verify by INPUT
"LOAD A" and "LOAD B" that calibration is correct
by checking the variation at several basket load-
ing condition, the difference between LOAD A
and LOAD B values should be less than a certain
value.
Setup - ACCELER (Calibrating Tilt Sensor)
This menu allows the calibration of the tilt sensor.
After replaced the master board (ECM1) or the tilt sensor
it's necessary to calibrate the tilt levelling system.
NOTE:
Ensure the tilt switch is mounted at distance of 0.59
in (15 mm) and securely attached on the bracket
plate, with the screws 5x45 TCEI and Loctite.
NOTICE
A NEW TILT MODULE WILL ACT AS IF IT IS TILTED ALL OF THE TIME
UNTIL THE FOLLOWING PROCEDURE IS PERFORMED.
DO NOT CALIBRATE THE LEVEL SENSOR EXCEPT WITH A MACHINE LEV-
ELLED. PLACE THE MACHINE ON OUTRIGGERS, WITH BOOMS IN
STOWED POSITION AND ALIGNED WITH THE BASKET EMPTY. ENGINE
AND ELECTRICAL MOTOR MUST BE SWITCHED OFF (AVOIDING VIBRA-
TIONS).
Start of the calibration procedure:
1.
Turn ON the main key and stabilize the machine.
2.
Place a level on the slew ring and ensure
machine is level.
3.
Press button n.6 (SERVICE) and then press but-
ton n.7 (SETUP).
4.
Press button n.5 (PASSWORD). The display will
ask for the password.
5.
