SECONDARY
BOOM ANGLE
SENSOR
11 Shorted to supply >4850 mV
· elevated drive
speed
· no elevated drive
due to tilt drive
cutout on CE units
Note: Driving at 2
MPH is allowed if
primary and
secondary angle
sensors are
calibrated and the
mV value is close
to the calibrated,
stowed value
Verify:
· 5V from TCON
C19-8 thru C3-15 to
sensor C15-C
· B- from C19-9 thru
C3-16 to C15-A
· Signal Output
approximately 1000 -
4000 mV across range of
motion at TCON C19-10
GY thru C58-5 from
C15-B (C124 SBS
RD/WH)
· Cycle Power with
problem corrected to clear
fault
To Calibrate:
Stowed mV must be
between 3600 & 4400 mV
Elevated mV must be
between 600 & 1400 mV
16 Value at 0v
0V
17 Not calibrated
Calibration Not
Completed
19 Out of Range
Reported angle
sensor value out
outside normal
range more than
3 degrees

Drive disabled
Verify:
· Engine speed signal =>
square wave
(HZ/frequency) at C20-1
TCON, C58-6 & C35-4
(C41RPM OR/BK)
· Confirm pump motor
speed signal=> square
wave (HZ/frequency) at
C34-31 and also C34-32
(D185SEN WH &
D186SEN BL)
Note: Approx. 6V DC
while turning, either B- or
12V when stopped.
