Length sensors:
Three length sensors are mounted to the boom base section to measure the overall length,
the inner mid section length and the center mid section length. The software utilizes the
signals to calculate the outer mid and fly section length.
Disengage the boom stop to retract the boom completely.
With retracted main boom the overall boom length signal is -500 mV (A101-X1/10). Use the
test pin MP 15 (AGND) or terminal A101-X1/8 (AGND) for reference ground. Disengage the
boom stop to retract the boom completely.
With retracted main boom the inner mid section length signal is -500 mV (A101-X1/24). Use
the test pin MP 15 (AGND) or terminal A101-X1/8 (AGND) for reference ground.
With retracted main boom the center mid section length signal is -500 mV (A101-X1/73). Use
the test pin MP 15 (AGND) or terminal A101-X1/8 (AGND) for reference ground.
Keep the cable on the length transducer drum spooled properly. A poorly spooled cable may causes the boom to
become out of sequence. If the boom becomes out of sequence, select manual mode and correct the length by
operating individual sections. Once the sections are sequenced again the operator may return to the automode.
Refer to section 9.1 for boom components installation and set up.
Inner mid retract and % reset switch:
The reset- proximity switch on the base section provides a (+24V) signal to central unit
terminal A 104 X1/80 when the inner mid section is retracted against the boom stop. The
signal resets the inner mid percentage to 1%.
The retract- proximity switch on the base section provides a (+24V) signal to central unit
terminal A 104 X1/78 when the inner mid section is fully retracted (disengage the boom stop).
