9.7 CALIBRATING THE JOYSTICKS

1. Position the Platform/Ground select switch to the
Platform position.
2. Pull out both Platform and Ground Emergency Stop
switches.
3. Enter Access Level 1 and scroll to the CALIBRATION
/ JOYSTICK screen.
4. Scroll to the joystick that needs to be calibrated (JIB
JOY -> MAST JOY -> X-AXIS JOY -> Y-AXIS JOY).
5. Hit ENTER to enter Joystick calibration procedure.
6. The screen will indicate 'FWD TO MAX' (or 'LEFT TO
MAX') : Tilt and maintain the Joystick fully forward
(or fully to the left).
7. Hit ENTER to acquire the joystick position.

8. The screen will indicate 'CENTER'.
9. Release the joystick and allow it to center.
10. Hit ENTER to acquire the joystick position.
11. The screen will indicate 'REV TO MAX' (or 'RIGHT TO
MAX') : Tilt and maintain the joystick fully reverse (or
fully to the right).
12. Hit ENTER to acquire the joystick position.
9.8 CALIBRATING THE PRESSURE RELIEF
VALVE
The PWM Pressure Relief Valve has a setting for each
movement. The different settings can be viewed / altered
by accessing to the personalities. The aim of the calibra-
tion procedure is to set all the pressure personalities in
one operation.
NOTE: After a complete reset of the system, setting the max-
imum pressure for all the movements is mandatory.
Calibrating the Pressure Relief Valve is the recom-
mended practice: it does not only set the maximum
pressure for all the hydraulic powered movements
but adjusts the response curves of the valve.
Although it is possible to set all the maximum pres-
sures by adjusting all the MAXP personality settings,
this will not adjust the response curves.
Before any pressure measurement or adjustment,
warm up the system by operating the different move-
ments.
Pressure measurement is to be performed with a
function operated at maximum speed.
1. Position the Platform/Ground select switch to the
Platform position.
2. Pull out both Platform and Ground Emergency Stop
switches.
3. Position the machine on a flat level ground. A mini-
mum up and over clearance of 7m is required.
4. Connect a pressure gauge to the dedicated port
(port "2" on the hydraulic power unit valve body).
5. Connect the Analyzer, Enter Access Level 1 and
scroll to the CALIBRATION / RELIEF VALVE screen.
6. Press ENTER to enter Relief Valve calibration sub-
menu.
7. The screen will indicate 'SET GEN PRESSURE' : Hit
ENTER.
8. The screen will indicate 'MAST TO MAX' and display
MAST, MAXP personality.
9. Fully raise the mast; at the end of the stroke of the
mast, read the actual maximum pressure.
10. Using the Up and Down arrows, adjust MAST, MAXP
personality in order to set the pressure at 17MPa
(±0.5MPa). Adjusting the personality must be done
when the system is idle (no movement is controlled).
11. When the correct pressure is set, Hit ENTER to com-
plete the Pressure Relief Valve Calibration (the sys-
