TWR LENGTH SENSOR TWO VALUE
OUT OF RANGE HIGH This fault is reported by the Ground module when the length sensor
value is outside the constant data limit
TWR LENGTH SENSOR TWO VALUE
OUT OF RANGE LOW This fault is reported by the Ground module when the length sensor
value is outside the constant data limit
TWR ANGL1 INVALID ANGLE Tower boom angle sensor #1 out of range
TWR ANGL2 INVALID ANGLE Tower boom angle sensor #2 out of range
INVALID ANGLE SENSOR #1 MODEL Wrong tower angle sensor Mfgr. Installed on a 1250AJP (Must be a
Rieker, not Spectron)
INVALID ANGLE SENSOR #2 MODEL Wrong tower angle sensor Mfgr. Installed on a 1250AJP (Must be a
Rieker, not Spectron)
MAIN ANGL1 INVALID ANGLE Main boom angle sensor #1 out of range
MAIN ANGL2 INVALID ANGLE Main boom angle sensor #2 out of range
MAIN ANGLE SENSOR NOT
DETECTING ANGLE CHANGE The main boom is being commanded to move and the main angle
sensors are not detecting any movement
MAIN ANGLE MOVEMENT WITH-
OUT CMD The main boom angle is changing without a main lift command
WRONG TWR TELE RESPONSE The tower telescope is moving in the opposite direction the user is
commanding.
WRONG TWR LIFT RESPONSE The tower lift is moving in the opposite direction the user is com-
manding
TWR CYL ANGLE SENSOR OUT OF
RANGE LOW The tower cylinder angle sensor is below 4721 A/D counts
TWR CYL ANGLE SENSOR OUT OF
RANGE HIGH The tower cylinder angle sensor is above 29535 A/D counts.
TWR CYL ANGLE NOT DETECTING
ANGLE CHANGE The cylinder angle is not changing during a tower lift up/down user
command.
TWR CYL ANGLE MOVEMENT
WITHOUT CMD The cylinder angle is changing without a tower lift command
MAIN TRN ANGLE SW FAILED The system detected a disagreement of the N.O. vs N.C. contacts on
the main boom angle switch.
TWR TRN SW DISAGREEMENT The system detected a disagreement between the tower boom
length switch and the tower length sensors.
TRN DUAL CAP SWITCHES BAD The system detected both the Dual capacity and the transport
switches are bad.
TRN DUAL CAP BAD TRANSITION The system detected that the Dual capacity or the transport
switches changed state out of order.
MAIN TRN LEN SW DISAGREEMENT The system detected a disagreement between the main boom
transport length switches.
DCAP LEN SW DISAGREEMENT The system detected a disagreement between the main boom dual
capacity length switches.
MAIN BOOM TRN ANGLE SW/SEN-
SOR DISAGREEMENT The system detected a disagreement between the main boom
transport angle switch and the main boom angle sensors.
CYL ANGLE SENSOR/SW DIS-
AGREEMENT The system detected a disagreement of the tower angle input from
the BLAM and the tower cylinder angle sensor.
