BLAM SENSOR SUPPLY OUT OF
RANGE HIGH Indicates that the supply voltage for the boom angle sensors is above the
expected range. An EMS cycle is required.
BLAM SENSOR SUPPLY OUT OF
RANGE LOW Indicates that the supply voltage for the boom angle sensors is below the
expected range. An EMS cycle is required.
LENGTH SENSOR REF VOLTAGE
HIGH Indicates that the supply voltage for the boom length sensors is above the
expected range. An EMS cycle is required.
LENGTH SENSOR REF VOLTAGE
LOW Indicates that the supply voltage for the boom length sensors is below the
expected range. An EMS cycle is required.
BLAM HIGH RES A/D FAILURE The high resolution Analog to digital converter in the BLAM module has failed.
An EMS cycle is required.
CHASSIS SENSOR SUPPLY OUT OF
RANGE LOW Indicates that the supply voltage for chassis sensors is below the expected
range. An EMS cycle is required.
CHASSIS SENSOR SUPPLY OUT OF
RANGE HIGH Indicates that the supply voltage for chassis sensors is above the expected
range. An EMS cycle is required.
