1. General Information
The DS 350 load moment indicator (LMI) with boom control extension is designed to aid the
crane operator through the crane operations. The DS 350 with boom control extension is not,
and shall not, be a substitute for good operator judgment, experience and use of accepted
safe crane operating procedure.

3. Warnings
The DS 350 load moment indicator (LMI) with boom control extension is an operational aid
that warns the crane operator when he approaches an overload condition, a two block
condition and an out of boom sequence condition. The boom control extension controls the
sequence of the boom during operation. It still remains the operator’s responsibility to verify
the operation and to select the correct mode during crane operations.
The manual mode is a rigging mode. Lifting loads with manual mode programmed is
prohibited.
Should an out of sequence condition occur, the crane operator is responsible to select
manual mode to return the sections into sequence before continuing the lift.
The responsibility for safe crane operation shall remain with the crane operator who shall
ensure that all warnings and instructions supplied are fully understood and observed.
Prior to operating the crane, the operator must carefully and thoroughly read and understand
the information provided by the crane and load moment indicator manufacturer.
Proper functioning depends upon proper daily inspection and observance of the operating
instructions provided with the crane and load moment indicator.

4. Service and Maintenance
Daily maintenance of the load moment indicator consists of inspecting:
1. The electrical wiring connecting the various parts of the system.
If electrical wiring is damaged, it shall be replaced immediately.
2. If the insulation is worn on the length sensor cable or cable guides are damaged, these
parts shall be replaced.
3. Check the anti two-block limit switches for freedom of movement.
4. The cable reel shall be under tension to operate properly.
5. Check the pressure transducers at the hoist cylinder(s) and the connecting hoses for oil
leakage.
Other than correcting the problems identified in the Malfunctions Table and replacing faulty
mechanical parts and cables, no other repairs shall be performed by non expert personnel.

Auto mode / Manual mode:
The operator selects auto mode or manual mode using the rocker switch in the dash board.
Auto mode is the working mode and manual mode is used for rigging or sequencing purpose
only.
Pilot pressure switch signal / Analog output signal:
Two pressure switches in the pilot pressure circuit are used to distinguish between boom
extend or boom retract. The two circuits are wired through the crane interface connector into
the DS 350 G central unit.
When the operator extends the boom, the pressure switch signal at central unit terminal
A101-X1/38 changes from 0V to +24V. The boom control logic allows electrical current to
flow to the extend pressure reducing valve coil. The minimum current equals 0 mA with the
control in neutral position. The maximum current output equals 800 mA.
To measure the coil current while extending, remove wire #20from central unit terminal
A101-X1/63. Connect the Amp-meter in series with wire #20 to terminal X1/63.
When the operator retracts the boom, the pressure switch signal at central unit terminal
A101-X1/40 changes from 0V to +24V. The boom control logic allows electrical current to
flow to the retract pressure reducing valve coil. The minimum current equals 0 mA with the
control in neutral position. The maximum current output equals 800 mA.
To measure the coil current while retracting, remove wire #21 from central unit terminal
A101-X1/64. Connect the Amp-meter in series with wire #21 to terminal X1/64.

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).

Center mid retract and % reset switch:
The proximity switch on the inner mid section provides a (+24V) signal to central unit terminal
A 114 X1/9 when the center mid section is fully retracted. The signal resets the center mid
percentage to 0%.
Refer to Parts & Installation Manual and follow the installation instructions for switch and target adjustment.
Outer mid/ fly retract and % reset switch:
The proximity switch on the center mid section provides a (+24V) signal to central unit
terminal A 114 X1/76 when the outer mid and fly section is fully retracted. The signal resets
the outer mid/ fly percentage to 0%.
Refer to Parts & Installation Manual and follow the installation instructions for switch and target adjustment.

Output for two- way valves:
A pair of two- way valves controls the oil to each tele- cylinder. The relay output K2, K6, K7
operates the pair of two- way valves in automode. The valve need to be de-energized to
operate the particular cylinder. The valves for the sections that are not selected are powered
to prevent movement of the other cylinders.
