LSS WATCHDOG RESET
The Watchdog Timer on Load Sensing System Module’s micro-
processor was triggered by exposure to excessive electrical
noise, or by a hardware difficulty.
9-1 Flash Code
LSS Module Message – Status Message (0x81) is reporting
“WATCHDOG RST” AND [Machine Setup’s LOAD is set to 1=CUT-
OUT PLT OR 2=CUTOUT ALL]. Retained until power is re-
cycled.
No motion interlocks.
Re-cycle power to clear diffi-
culty

LSS EEPROM ERROR
Memory used to retain settings on Load Sensing System Mod-
ule has been corrupted and must be reset by verifying all
entries / re-calibrating.
9-2 Flash Code
LSS Module Message – Status Message (0x81) is reporting
“EEPROM ERROR” AND [Machine Setup’s LOAD is set to 1=CUT-
OUT PLT OR 2=CUTOUT ALL]. Retained until power is re-cycled.
Vehicle assumed to be Overloaded
After resolution, re-cycle power
to clear difficulty.

LSS HAS NOT BEEN CALIBRATED
9-3 Flash Code
The Load Sensing System’s Calibration EEPROM for Empty Plat-
form Load is set to Never Set (signature implanted by the In-
Circuit Test Fixture) AND [Machine Setup’s LOAD is set to
1=CUTOUT PLT OR 2=CUTOUT ALL]. Retained until Calibration
EEPROM is over-written by a valid calibration.
Vehicle assumed to be Overloaded.
Calibrate the Load Sensing Sys-
tem using the calibration proce-
dure to clear the message.
