1 GENERAL INFORMATION
The PAT Load Moment Indicator1(LMI) DS 350 has been designed to provide the crane operator
with the essential information required to operate the machine within its design parameters.
Using different sensing devices, the Load Moment Indicator monitors various crane functions
and provides the operator with a continuous reading of the crane’s capacity. The readings
continuously change as the crane moves through the motions needed to make the lift.
The LMI provides the operator with information regarding the length and angle of the boom,
working radius, rated load and the total calculated weight being lifted by the crane.
If non permitted conditions are approached, the DS 350 Load Moment Indicator will warn the
operator by sounding an audible alarm, lighting a warning light and locking out those functions
that may aggravate the crane’s condition.
1LOAD MOMENT: generally the product of a force and its moment arm; specifically, the product of the load and the load-radius. Used in the
determination of the lifting capacity of a crane

2 WARNINGS
The LMI is an operational aid that warns a crane operator of approaching overload conditions
and of 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 safe crane operation remains 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.
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 manual.
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.

3 SYSTEM DESCRIPTION
The PAT Load Moment Indicator DS 350 consists of a central micro processor unit, operating
console, length/angle sensor, pressure transducers, and anti-two block switches.
The system operates on the principle of reference/real comparison. The real value, resulting
from the pressure measurement is compared to the reference data, stored in the central
processor memory and evaluated in the micro processor. When limits are reached, an overload
warning signal is generated at the operator’s console. At the same time, the aggravating crane
movements, such as hoist up, telescope out 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.
Boom length and boom angle are registered by the length/angle sensor, mounted inside the
cable reel which is mounted on the boom. The boom length is measured by the cable reel cable
which also serves as an electrical conductor for the anti two-block switches.
The crane load is measured by pressure transducers attached to the piston and rod side of the
hoist cylinders.
The interactive user guidance considerably simplifies the input of operating modes as well as
the setting of geometry limit values.

3.1 System Function
Upon switching on, the system starts with
an automatic test of the LMI system, of
lamps and audible alarm. During the test,
the LC display shows the initial logo.
If the system was turned off for more than
two hours, the setup configuration has to
be entered after the system test. (⇒
chapter 4)
First, the operating mode is determined by
an interactive step-by-step interrogation of
the rigging states.
Next is the interactive input of the reeving.
Now the LC display shows in symbols all
inputs and awaits acknowledgment or
canceling.
Upon acknowledgment of the inputs the
system is ready for operation.

3.2 Operating Console
The console has 3 functions:
• Inputs by the crane operator (operating mode, reeving)
• Input of geometry limit values and signalization of exceeded limit values
• Display of important data and information
The operator’s console is mounted in the crane’s cab in the operator’s field of vision. For a
better identification of displays and operating elements, they are continuously backlit during
operation.

4 CONFIGURATION SETUP
The LMI setup procedure allows the operator to input the crane configuration using interactive
displays. The operator must complete the setup procedure for the Load Moment Indicator
system if the system has been turned off for more than two hours or the crane operation
configuration has been changed.
4.1 LMI Setup Procedure
...starts: • Automatically, if the system was turned off for more than
two hours.
• Manually at each modification of the crane configuration by
pressing key (9) "SEL"
...is operated: • By answering the different questions using functional keys
F1...F4 in accordance with the actual configuration of the
crane.
...is cancelled: • Any time by pressing again key (9) "SEL". The system,
however, is only ready for operation, if the procedure has
been completed and the inputs have been confirmed.
If the system is turned off, for example during short breaks (less than 2 hours), all adjustments
remain stored. When turning on again the system these adjustments can be acknowledged by
merely pressing one key (provided that the crane configuration has not been modified!).
During the programming procedure, the Load Moment Prewarning Light (3) and the Load
Moment Limit Light (2) will light up and the aggravating crane movements will be interrupted.
Note: If a configuration is selected which is not available, the display will indicate error code
E04. In this case, the procedure has to be repeated with valid values!
The correct setting is of utmost importance for the proper functioning of the system and the
crane. Therefore, only operators who are thoroughly familiar with the crane and the
operation of the system should execute the setting of the system according the operating
configuration of the crane.
