OPERATOR’S SECTION
1. GENERAL INFORMATION
The PAT Length-Angle-Radius-Load Indicator System EI 65 has been designed to provide the
crane operator with the essential information required to enable the machine to be used
within its design parameters. The EI 65 System indicates the length and angle of the boom,
tip height, working radius and the total calculated weight being lifted by the crane.
Using various sensing devices, the EI 65 System warns the crane operator of certain
approaching hazardous conditions which could occur during the operation of his crane.
The purpose of this operator’s manual is to provide information to help him operate, maintain
and troubleshoot the PAT System.
The manual contains the system description, operating, and calibration information.
2. WARNINGS
• The EI 65 is an operational aid that warns a crane operator of certain approaching
hazardous 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 operation of the crane 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 the indicator and crane.
• Proper functioning is dependent upon proper daily inspection and observations of the
operating instructions set forth in this manual.
Always refer to operational instructions and load charts provided by the
crane manufacturer for specific crane operation and load limits.

3 SYSTEM DESCRIPTION
The PAT EI 65 System consists of an operating console with central micro processor unit,
length/angle sensor, force transducers and anti-two block switches.
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 that also serves as an electrical conductor for the anti-two block switches.
The crane load is measured by running line tensiometers attached to the upper side of the
boom.
3.1 System Function
After ignition of the engine, the system starts with an automatic test of all lamps, the audible
alarm and the complete system.
After the system has passed through the system test without errors, the system will request
the operator to confirm the boom and jib configuration data. This allows the operator to
compare the system configuration with the actual crane configuration. (see Section 4.1).
After the operator confirms the system configuration, the console will indicate, on the display
(13), the actual load, tip height, boom length, boom angle, and radius.

During crane operation the readout will display the actual load, the tip height, the boom
length, the boom angle, the working radius, the selected hoist winch and the number of
reevings (parts of line). In case of a system error an error code is displayed in place of the
reevings.
During the setting procedure of the Operating Conditions and the limit setting procedure the
display shows the setting values and information for the operator.
4 PROGRAMMING PROCEDURE
During the startup phase the PAT System EI 65 automatically starts with a programming
procedure which relies on the correct entry by the crane operator.
This procedure consists of three parts:
• Startup Procedure
• Setting operating configuration of the crane
• Setting the preset limits
For simple operation, the computer guides the operator through the procedure step by step.
The operator has to read the information displayed and is instructed to answer questions by
using appropriate buttons of the keyboard. During each step of the procedure particular
button lights will come on to identify the possible choices for the step.
4.1Startup Procedure
After ignition of the engine the system starts the Startup Procedure with a self test.
During the Startup Procedure the crane operator will confirm the preset configuration stored
in system memory as described below. The operator will compare the preset operating
configuration values with the actual crane configuration.

OPERATOR’S SECTION

If there is a difference between the indicated and the actual condition, the operator must
correction those values by completing step 1 to 14 in Section 4.2.2.
The system stores the preset values for minimal 2 hours when the crane voltage is switched
off. After a loss of the preset values the operator will need to reset these values.
The display shows the previously programmed boom and jib
configuration. The crane operator can compare the preset
Operating Configuration Values with the actual crane
configuration. To confirm the displayed values push the button “OK” (10).
To change the configuration values go to one of the following sections. If the system
configurations are correct, go to Section 5 PRE-OPERATION INSPECTION.
• Section 4.2 will allow the operator to change all crane configurations.
• Section 4.2.1 will allow the operator to quickly change Reeving only
• Section 4.2.2 will allow the operator to quickly to change Hoist selection only.

an blinking colon.
For simple operation the computer guides the operator through the procedure step by step.
The operator has to read the information displayed and is instructed to answer questions by
using appropriate buttons of the keyboard. During the Setting Procedure the lamp in the
particular button lights up.
After a loss of the preset values the system sets the values of the Preset Limits on maximum
or minimum and deactivates all preset limits. This can happen, when the system is longer
than 2 hours without supply voltage.
The Activating and Setting Procedure can be started by the crane operator by pushing the
