3. SYSTEM DESCRIPTION
The PAT EI65 System consists of an operating console with a central microprocessor unit,
length/angle sensor, force transducers and anti-two block switches.
Boom length and boom angle is 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 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 (Refer 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. If an error occurs, refer to Section 8 and the error code
list.
In case of a lattice boom crane or if the crane is equipped with a jib, the operator has to confirm the
boom and jib configuration data after the system test and before normal operation (refer to Section 4
