WARNING :
A miscalculation of the lines of rope, could
lead to danger situation
To modify the line of rope, please proceed as
follows:
• Press the button 10 until on the display

is shown.
• Press button 8 to increase or 9 to decrease

AUTO
AUTO- -DIAGNOSTIC DIAGNOSTIC
Can the LMI detect faults?
Of course. To be considered a reliable system, it must be
able to perform self-check in order to detect internal or
components faults.
The LMI is equipped of an auto diagnostic system which is able to detect faulty pressure
transducers, or boom angle/length sensors, broken cables or internal electronic faults.
When an alarm occurs, the LMI puts itself in a safe condition stopping the dangerous
movements and at the same time the display shows an alarm message ( zone 1.8).
According to alarm code and message, it will be possible to identify the fault.
The codes are reported in the following list, that also includes some hints to solve the
problem and get back to normal working conditions.
