• Automatic levelling failure
1- Loss of ground contact during the automatic levelling sequence.
If an outrigger is no longer in firm contact with the ground:
➢ The levelling sequence is interrupted.
➢ An acoustic alarm (continuous sound) is triggered if the extension movement of
the outriggers is controlled.
➢ The outriggers can only be retracted.
- Check the condition and resistance of the ground or the absence of objects under the
outrigger pads.
- Possibly move the machine on firmer grounds.
Before a new attempt is made to automatically level the machine, the four outriggers must be
retracted until none contact the ground (system reset).
2- Outrigger cylinders reaching the end of their course or tilt aggravation detection.
If the outriggers reach the end of their course before the chassis is level or if the chassis tilt
gets worse instead of being corrected:
➢ The levelling sequence is interrupted.
➢ An acoustic alarm (continuous sound) is triggered if the extension movement of
the outriggers is controlled.
- Check the condition and resistance of the ground.
- Possibly move the machine on a surface where it will be possible to level the machine.
• Loss of ground contact
In case of ground contact loss when the platform is raised:
➢ The red outrigger position indicator lights up.
➢ An acoustic signal sounds.
➢ The green ground contact indicator of the corresponding outrigger switches off.
➢ All the movements from the platform control station or from the ground control station
are disabled.
-NOTE-
A specific procedure makes it possible to the work platform in the event an outrigger
looses contact with the ground or if the authorised tilt on outriggers is exceeded. Refer
to Section 7.2- Neutralisation of safety devices
4.6 GENERATOR (OPTION)
The onboard generator supplies the
work platform with AC current. The
output voltage as well as the maximum
power may vary function of the
generator type installed. Refer to the
data plate on the generator.
