General Information 1

Operator's Manual
DS 350 / 1334
The RCL 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 RCL has to
be ensured before starting the crane operation.
1 GENERAL INFORMATION
The PAT Rated Capacity Limiter (RCL) 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 Rated Capacity Limiter 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 RCL provides the operator with information regarding the 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 Rated Capacity Limiter 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.
2 WARNINGS
The RCL 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 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.
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 Rated Capacity Limiter DS 350 consists of a central microprocessor unit, operating
console, angle sensor, line riders, 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 aggravating crane movements,
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 line rider signals.
The hoist load is measured by line riders mounted on top of the boom, close to the tip.
The interactive user guidance considerably simplifies the input of operating modes as well as the
setting of geometry limit values.

System Function
Upon switching on crane ignition switch, the system starts
with an automatic test of the RCL system, of lamps and
audible alarm. During the test, the LC display shows the
initial logo. (approximately 35seconds)
The previous configuration setup will be displayed showing bold
symbols as selected inputs and must only be confirmed OK if
that configuration setup equals the crane’s actual configuration.
Otherwise it must be deleted to enter a new configuration. ( 
chapter 4)
The operating configuration is determined by an interactive
step-by-step interrogation of the rigging states and reeving.
(chapter 4)
The configuration setup entered will be displayed showing
bold symbols as selected inputs and must be confirmed OK
to set the system into operation or deleted to enter a new
configuration. ( chapter4)
Upon acknowledgment of the inputs the system is ready for
operation.

Operating Console
The console has 3 functions:
inputs by the crane operator (operating configuration, reeving, and calibration)
input of geometry limit values and signalization of exceeded limit values
display of important data andinformation
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.
LC Display
The LC display (LCD) used in the PAT DS 350 operator’s console is a high-resolution, wide
temperature-range component with transflective characteristics that give it a high visibility in
sunlight and during backlit night operation. Due to the nature of any LCD, it works on the
principle of polarization of light. It should be noted that dual polarizations that are at a certain
angle to each other can reduce the amount of light up to completely eliminating it if that angle
becomes perpendicular. This can have significance if the operator is wearing polarized
sunglasses that happen to be at perpendicularly polarized in relation to the LCD’s polarization. In
this rare case, the operator has to work without sunglasses or find different sunglasses that do
not have this characteristic, in order to avoid having the visibility of the display impaired.
The LCD contains an automatic temperature compensation that will adjust the LCD’s contrast
according to the surrounding temperature. In case of rapid or drastic temperature changes, it might
be advisable to support this automatic function by using the manual contrast adjustment feature. (
