CONNECTING THE JLG CONTROL SYSTEM
ANALYZER
1. Connect the cable supplied with the Analyzer to the
host control system located at the ground controlsta-
tion. There is also an alternate connection on the
under side of the platform control station. Connect
the remaining end of the cable to the analyzer.
NOTE:
The cable has a four-pin connector at each end of
the cable; The cable cannot be connected back-
wards.
2. Power-up the Control System by turning the key to
the Platform or Ground position and pulling both
emergency stop buttons.

HELP MENU & FAULT CODES
The Help Menu is a troubleshooting tool to communi-
cate detected System Faults to the technician. The fol-
lowing table documents the Faults for the Load Sensing
System. To access the Help Menu, use the LEFT and
RIGHT arrow keys to select HELP: PRESS ENTER from the
Top Level Menu. Press the ENTER key to view the menu.
When accessing the Help Menu, the JLG Analyzer will
display EVERYTHING OK if the platform is not over-
loaded and no difficulties are detected. Otherwise, the
JLG Analyzer will display OVERLOADED.
In the event of difficulty, the user can press ENTER again
to display Logged Help, which is a record of the last 16
Fault Messages. The following table lists each Help/
Logged Message, the Flash Code (for each Fault, the
module will flash the two-digit code on its LED) trig-
gered by the Fault, and a Description of the Situation
(cause).

CODE
DESCRIPTION OF SITUATION
PLATFORM OVERLOADED
2-5
The platform load measured at the Load Sensing System is excessive. Functions from the platform control are prevented, and func-
tions from the ground control may be prevented, depending on machine.
BATTERY TOO HIGH
4-4
Incoming Supply Voltage >34.0 Vdc. The control system’s battery voltage is too high. This may be due to over-charging or improper
charger operation.
BATT TOO LOW
4-4
Incoming Supply Voltage <9.0 Vdc. The control system’s battery voltage is too low due to excessive electrical load or discharge. This
may compromise ability to predict weight. Recharge batteries or check for damaged batteries.
CANBUS FAILURE: LSS
MODULE
6-6
The control system failed to receive messages from the LSS Module. Check wiring at the LSS Module and along scissor arms leading
up to platform.
CELL #1 ERROR
8-1
Cell #1’s Bridge <2V, >3V, or could not read Cell #1’s Internal Memory. This situation indicates damage to the sensor or its wiring.
CELL #2 ERROR
8-2
Cell #2’s Bridge <2V, >3V, or could not read Cell #2’s Internal Memory. This situation indicates damage to the sensor or its wiring.
CELL #3 ERROR
8-3
Cell #3’s Bridge <2V, >3V, or could not read Cell #3’s Internal Memory. This situation indicates damage to the sensor or its wiring.
CELL #4 ERROR
8-4
Cell #4’s Bridge <2V, >3V, or could not read Cell #4’s Internal Memory. This situation indicates damage to the sensor or its wiring.
WATCHDOG RST
9-1
Microprocessor’s Watchdog Timer Triggered. This is an indication that the LSS Module has been exposed to excessive electrical
noise, or has experienced a hardware difficulty.
EEPROM ERROR
9-2
Memory used to retain Personality/Machine Setup/Calibration has been corrupted and must be reset by verifying all entries and
re-calibrating. After resolution, re-cycle power to clear difficulty.
LSS NOT CALIBRATED
9-3
Calibration has not been successfully completed. A new LSS Module will display this message until properly calibrated.
LSS INTERNAL ERROR - PIN
EXCITATION
9-9
Pin excitation <4.25 V. The sensors may be excessively loading the excitation supply, or the LSS Module may have hardware diffi-
culty.
LSS INTERNAL ERROR -
DRDY MISSING FROM A/D
9-9
DRDY Interrupt from LSS Module’s A/D converter missing. This may indicate an LSS Module hardware difficulty.
