1 GENERAL INFORMATION
The PAT Load Moment Indicator1(LMI) DS 350 has been designed to provide the crane
operator with essential information required to operate the machine within its design
parameters.
This low temperature system uses heaters for stable system operation in a subzero
climate. The main electronics are automatically warmed before the system boards and
components are energized. Therefore, all system components must be installed and
sealed from the environment when operating and/or troubleshooting in low temperature
conditions.
Using a variety of 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 necessary 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 calculated total weight being lifted by the crane.
If prohibited conditions are approached, the DS 350 Load Moment Indicator will warn the
operator by sounding an audible alarm, lighting a warning light, and rendering
inoperative 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 overhoist 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 in this manual and supplied by the crane
manufacture 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 anti-two block switches must be used in ALL operations. Simultaneous
two-hoist working is prohibited in all circumstances.
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. This low temperature system uses heaters for stable system operation in a
subzero climate. The main electronics are automatically warmed before the system boards
and components are energized. In low temperature conditions, a warm-up period is
required.
The system operates on the principle of reference/real comparison. The real value,
resulting from the pressure measurement is compared with the reference data, which is
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.
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
While the system is switching on, it starts with an
automatic test of the LMI system, lamps and audible
alarm. During the test, the LC display shows the initial
logo. Note during low temperatures the LC display will
not show the graphics, or be-come operational, until the
console heater has warmed the electronics.
The previous configuration setup will be displayed
showing bold symbols as selected inputs and must
only be confirmed OK if that configuration setup
corresponds with the crane’s actual configuration.
Otherwise it must be deleted to enter a new
configuration. (⇒chapter 4)
The operating mode is determined by an interactive
series of questions about the rigging states.
Now the LCDisplay shows in symbols all inputs and
awaits verification or cancellation.
The system is ready for operation after verification of
the data .
3.2 Operating Console
The console has 3 functions:
•Inputs by the crane operator (operating mode, reeving)
•Input of geometry limit values and notification 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. The
displays and operating elements are continuously backlit.

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 matching 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 less than 2 hours (during short breaks), all adjustments remain
stored. When turning the system on again, these adjustments can be acknowledged by
merely pressing the “OK” function key if the crane configuration has not been modified.
Note during low temperatures the LC display will not show the graphics, or become
operational, until the console heater has warmed the electronics.
For extended travel on tire without load, Press the “SEL” button to silence the alarm.
NOTE: When the “SEL” button is pressed and no operating configuration is selected, the
boom down and tele out functions are locked out because the LMI is not in operation.
