16. DMU Diagnostics - Trouble shooting
In case a fault is in the DMU system, the fault may be identied if you look at the lights that light up on
the DMU main panel, see which ones are ashing and observe how they ash, and the sound emitted.
Here are some indications from main panel relating to faults.
The nal part of the chapter also reports some indications of work situations which may be provided
by main panel.
Note: During the diagnostic work it is important that the acoustic alarm is not disabled to have
an indication on the exact type of sound.
NOTE: The LED light that ashes on the DMU main panel shows the position of crane boom where
the failure is.
