1 GENERAL INFORMATION
The PAT Load Moment Indicator1(LMI) DS350 has been designed to provide the crane operator with
the essential information required to operate the machine within its design parameters.
DS350 LMI basically consists of a central microprocessor unit, graphic operator’s console, angle
sensor, force transducer sensor, and anti-two block switches. The system operates on the principle of
reference/real comparison. The real value, resulting from the load measurement is compared with the
reference data, stored in the central processor memory and evaluated in the microprocessor. If non
permitted conditions are approached, the DS350 LMI will warn the operator by sounding an audible
alarm, lighting a warning light and locking out those functions that may aggravate or worsen the
crane’s condition.
The fixed data regarding the crane, such as capacity charts, boom weights, centers of gravity and
dimensions are stored in memory chips in the central processor unit. This data is the reference
information used to calculate the operating conditions.
The boom angle is measured by the angle sensor, mounted at the boom base. The cable reel cable
serves as an electrical conductor for the anti two-block switches and force transducer signals.
The hoist load is measured by a force transducer mounted in the pendant, close to the boom tip.
The operator’s console uses interactive graphic illustrations to guide the operator through the
configuration setup and calibration programming, which considerably simplifies the input of operating
modes as well as the setting of geometry limit values.
The configuration setup allows the operator to define the crane current configuration, which the
computer uses to set the operating mode and define the limits for the crane configuration.
A calibration is required to define the load, radius, and boom angle for a specific crane configuration.
The calibration adjusts boom weights, deflection, and offsets in main boom and extension
configurations, which will be used to calculate the load moment to aid the operator in determining the
crane limits for the specific operating configuration. Refer to chapter 9 for further information.
NOTE: The zero setting of the force transducer requires that the pendent be disconnected, so
there are no external forces on the transducer.

Operation, Calibration & Service Manual
LinkBelt - DS350 1334 Console
The LMI can only work correctly, if all adjustments have been properly set. For correct adjustment,
the operator has to answer thoroughly and correctly all questions asked during the setup procedure
in accordance with the real rigging state of the crane. To prevent material damage and serious or
even fatal accidents, the correct adjustment of the LMI has to be ensured before starting the crane
operation.
2 WARNINGS
The LMI is an operational aid that warns a crane operator of approaching overload conditions and
over hoist conditions that could cause damage to equipment and personnel.
The device is not, and shall not, be a substitute for good operator judgment, experience and use of
accepted safe crane operating procedures.
The responsibility for the 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 in this manual to ensure that he knows the operation and limitations of indicator and
crane.
The use of load or angle sensor bypass plugs for pile driving applications will render the system
inoperable from proper function and operation, and is not recommended. But, the option is available
to prevent momentary cutout conditions due to spiking load indications that may occur or interfere with
the pile driving application. After performing this application, the system must be returned to its normal
working condition with all sensors connected, and bypass plug removed. The pre-operation inspection
and calibration verification in SECTION 6 of this manual MUST be performed.
Proper functioning depends upon proper daily inspection and observance of the operating instructions
set forth in this manual. Refer to Section 6. Pre-Operation Inspection and Calibration Verification of
this handbook.

3 SYSTEM DESCRIPTION
The PAT Load Moment Indicator DS 350 consists of a central microprocessor unit, operating console,
angle sensor, force transducer, and anti-two block switches.
The system operates on the principle of reference/real comparison. The real value, resulting from the
load measurement is compared with the reference data, stored in the central processor memory and
evaluated in the microprocessor. When limits are reached, an overload warning signal is generated at
the operator’s console. At the same time, the crane functions, such as hoist up and boom down, will be
stopped.
The fixed data regarding the crane, such as capacity charts, boom weights, centers of gravity and
dimensions are stored in memory chips in the central processor unit. This data is the reference
information used to calculate the operating conditions.
The boom angle is measured by the angle sensor, mounted in the boom base. The cable reel cable
serves as an electrical conductor for the anti two-block switches and force transducer signals.
The hoist load is measured by a force transducer mounted in the pendant, close to the boom tip.
The interactive user guidance considerably simplifies the input of operating modes as well as the
setting of geometry limit values.
