PLATFORM MODULE SOFTWARE
UPDATE REQUIRED
Platform module code is too old to support the EIM or BPE load sensor and the machine
is configured to use one of these two sensors. The PM code must be updated to a newer
version.
HIGH RESOLUTION A2D FAILURE –
INTERRUPT LOST
The ADS1213 chip in the platform module has stopped asserting its interrupt (DRDY)
line for some reason. An EMS cycle is required.
HIGH RESOLUTION A2D FAILURE-
REINIT LIMIT
The ADS1213 has needed to be reset 3 or more times.
PLATFORM MODULE FAILURE:
hwfs CODE 1
Platform module Flow) FET has failed
GROUND MODULE FAILURE: hwfs
CODE 1
Ground module V(Low) FET has failed
GROUND SENSOR REF VOLTAGE
OUT OF RANGE
These faults occur when the seven volt reference voltage used for the joysticks, sen-
sors, etc goes out of range. Not reported during 2 second power-up.
PLATFORM SENSOR REF VOLTAGE
OUT OF RANGE
These faults occur when the seven volt reference voltage used for the joysticks, sen-
sors, etc goes out of range. Not reported during 2 second power-up.
EEPROM FAILURE – CHECK ALL
SETTINGS
A critical failure occurred with the EEPROM. Personalities, machine configuration dig-
its, etc may be reset to default values and should be checked.
CHASSIS TILT SENSOR NOT GAIN
CALIBRATED
Indicates that the chassis tilt sensor calibration information has been lost. Machine will
indicate that it is tilted at all times. This calibration data is programmed into the unit at the
factory.
CHASSIS TILT SENSOR GAIN OUT
OF RANGE
Indicates that the chassis tilt sensor calibration has become corrupted.
INCOMPATIBLE SOFTWARE
DETECTED
The UMS module detects that the Ground module software is incompatible with the
UMS module
