CALIBRATION PREPARATION
The following procedure must be executed to prepare
for calibration and verification.
IF THE CALIBRATION MUST BE PERFORMED OUTDOORS, ENSURE THE
FOLLOWING ADDITIONAL CONDITIONS ARE MET BEFORE BEGINNING
CALIBRATION PROCEDURES:
•
MACHINE IS ON A SLOPE LESS THAN OR EQUAL TO
0.5 DEGREE
.
• WIND SPEED IS LESS THAN OR EQUAL TO 20 MPH
(32 KPH).
• CALIBRATION WEIGHT IN THE PLATFORM IS CEN-
TERED AND EVENLY DISTRIBUTED.
1. Ensure the batteries are fully charged (24.5V or
greater) and hydraulic fluid level is acceptable.
2. Resolve any active control system faults before
attempting calibration.
3. Park the vehicle on a level surface. The platform
should be fully stowed and level /- 0.5
degrees in both directions.
4. Ensure the vehicle temperature is at least +32°F/0°C
degrees Fahrenheit.
5. Complete Elevation Sensor calibration before
attempting to calibrate the LSS.
6. Set key switch to Ground Mode.
7. Fully lift down to the stowed position.
8. Remove all foreign materials and debris from the
deck.
9. Install any JLG Accessories that will be permanently
attached (Electrician's Tree, Panel Carrier, etc.).
10. Connect the JLG Analyzer to the diagnostic port in
the wire harness and enter the Access Level 1 pass-
word.
11. Adjust the PERSONALITY ' LOAD ' ACC'Y setting
(See
according to the documentation fur-
nished with the factory-provided accessories or con-
sult JLG.

DESCRIPTION
CALIBRATIONS:
LOAD 0%
CAL LOAD:
YES:ENTER;NO:ESC
Press ENTER to begin calibration or ESC to exit
CAL LOAD:FAIL
NOT IN GND MODE
Vehicle must be calibrated in Ground Mode. Set the keyswitch to Ground Mode and retry.
CAL LOAD:FAIL
CAL ANGLE
Elevation sensor must be fully calibrated. Follow procedure at CALIBRATIONS -> SET STOW ELEV
and CALIBRATIONS -> SET MAX ELEV and retry.
CAL LOAD:
PLATFORM EMPTY?
Verify the platform is empty and continue by pressing ENTER, or exit by pressing ESC.
CAL LOAD:FAIL
PLAT NOT STOWED
Vehicle must be fully stowed. Lift down and retry.
CAL LOAD:
LIFT TO MAX ELEV
Engage lift up so the control system can gather dynamic calibration information until the plat-
form reaches maximum height and then press ENTER
CAL LOAD:
LOWER TO STOWED
Engage lift down so the control system can gather dynamic calibration information until the plat-
form reaches the stowed position
CAL LOAD: FAIL
BATT < 24.5 V
On 3246R, if system voltage is below 24.5 V at the beginning of 0% or 110% calibration proce-
dures, voltage is allowed to drop below 24.5 V while calibrating and pump is running.
CAL LOAD:FAIL
MOTION STOPPED
Lift motion was interrupted and calibration could not be completed
CAL LOAD:
COMPLETE!
Load Sensing System calibration was successful
CAL LOAD:
CAL FAIL
Load Sensing System calibration was not successful so the original values were retained; retry
