SECTION 9 - JLG CONTROL SYSTEM

9.4 CALIBRATION INSTRUCTIONS

All calibration procedures are menu driven through the
use of the standard JLG analyzer (connected to the con-
trol system on the bottom of the platform control box). The
user is prompted to exercise the machine in a specific
order to use the machines physical properties to consis-
tently establish sensor response and the interaction of
valves, pump and motors.
The chart below lists the calibrations required and poten-
tial reasons for re-calibration.
Calibration Procedure
Master or Slave module replacement
Steer sensor removal or replacement
Steering spindle or steering pin removal
Steer Sensor
or replacement
Drive speeds out of tolerances
Switch removal or replacement
Platform replacement
Rollers replacement
Overload Switch
System parameters reset
Load control inaccuracy
Master or Slave module replacement
Joysticks replacement
Joysticks
Platform console inoperative
Master or Slave module replacement
Pressure Relief Valve replacement
Relief Valve
Hydraulic power pack replacement
Movement speeds out of range
NOTE: If the system is reset (by changing the machine
model), the steer sensor, the joysticks and the pres-
sure relief valve must be re-calibrated.
NOTE: The tilt sensor is not calibrated using the analyzer
(Refer to § 8-2 for the appropriate procedure).

9.5 CALIBRATING STEERING SENSOR

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.
4. Enter Access Level 1 and scroll to the CALIBRATION
-> SET STEER SENSOR screen.
5. Press ENTER to enter Steer Sensor calibration sub-
menu.
6. Hit ENTER again to begin the calibration process.
7. The screen will indicate 'LEFT TO MAX' : Activate the
steer control until the wheels are fully steered to the
left (you may drive for a limited distance while steer-
ing to ensure the mechanical stop is reached).
8. Hit ENTER to confirm.
9-6
Reasons for Re-calibration
9. The screen will indicate 'CENTER' : Activate the steer
control until the wheels are straight in relationship
with the chassis.
Figure 9-2. Wheel Straightening
10. Hit ENTER to confirm.
11. The screen will indicate 'RIGHT TO MAX' : Activate
the steer control until the wheels are fully steered to
the right (you may drive for a limited distance while
steering to ensure the mechanical stop is reached).
12. Hit ENTER to confirm.
13. After completing the Steer Sensor calibration, hit
ESC twice to go back to CALIBRATIONS.

9.6 CALIBRATING OVERLOAD SYSTEM

Calibrating the overload system is a mechanical opera-
tion. The procedure through the analyzer is established to
help the technician by removing the delay timers in the
system : the alarm will directly give the overload switch
status. Calibrating the overload system will clear the fault
'LSS HAS NOT BEEN CALIBRATED' : this fault is, by
default, present on all new system.
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.
4. Enter Access Level 1 and scroll to the CALIBRATION
-> SET OVERLOAD SW screen.
5. Press ENTER to enter Overload Switch calibration
sub-menu.
6. Position a 220kg load evenly distributed on platform
floor.
