ACCESS PROCEDURES ACCESS PROCEDURES LOAD MONITORING SYSTEM (LMI) LOAD MONITORING SYSTEM (LMI) This systems has been conceived and developed to offer two different levels of functionality of access to internal data, according to the actions to be done. The basic access level (Operator) does not need any password; this one, in fact, is required for possible assistances, only by Technical Service Personnel (failure detecting and repairing). - Page 4 COMPONENTS LOCATION ON THE MACHINE COMPONENTS LOCATION ON THE MACHINE Length sensor Used in case of boom indipendent sections Length/Angle sensor Control Panel : into the cabin Nr.2 Pressure Transducers: On the lifting cylinder.

Page 14: Troubleshooting
TROUBLESHOOTING TROUBLESHOOTING The first step to seek a fault is to identify the problem which occurred to the machine Operator. Thanks to the auto-diagnostic procedures, which are able to recognise transducers failures, cable breaking and internal electronic faults,alarm codes are automatically shown on the display, allowing the operator to a certain capability of repairing, and also to better inform the Technical Assistance even remotely. - Page 15 ALARM CODES AND ACTIONS TO TAKE ALARM CODES AND ACTIONS TO TAKE Alarm Description What to do code • Switch the system off and on.

Page 18: Alarm Code
ALARM CODE 56 : MEMORY DATA NOT RELIABLE CAUSE: All the calibration data are stored in four EEPROM 24C65. Through the “Check-sum” equation, software checks continuously the result to the original memorised value. When detecting a difference, the display will show the following message : ALARM 1 = memory data not reliable. - Page 19 ALARM CODE 15 : ANGLE TRANSDUCER READING LOWER THAN THE MINIMUM VALUE(*) CAUSE: The signal from the angle transducer to the main PC board is lower than the minimum programmed value. This can be produced by a short-circuit in the electrical wiring, between the Main Unit and Sensor or the sensor itself is in interdiction.
