Operation and Maintenance
20
Caution !
Whilst raising the arm, the system automatically manages the necessary
combination the movements for lifting and telescoping the arm. The
machine itself carries out a complementary movement to the controlled
movement, in order to keep the machine within the limits of the stability
zone. The arm and the fly jib are equipped with length and angle sensors
to fulfil these functions.
3.2.8 - Defects
When the machine is deployed, it
must always remain under power so
that the safety systems are active.
The machine is equipped with internal defect detection systems. The
number of flashes (1 to 9) of the defect indicator indicates to the user the
nature of the anomaly: refer to the table "Operating incidents" in chap. 6,
page 49 for the description of each type of defect. According to the nature
of the anomaly, the machine may switch to BASIC MODE: certain
movements may be limited or prohibited by the system to keep the user
safe.
.
Procedure :
• note the number of flashes emitted by the defect indicator, if any other
indicators are lit, and the state of the machine at the time that the de-
fect occurs
• use the controls to retract the telescope and fly jib lift to bring the plat-
form back inside the grey zone (see diagramme).
• fold the machine.
• forbid its use until the defect is repaired
• refer to chap. 6, page 49 "Operating incidents " to remedy the defect.
NOTE : If the user presses on the emergency stop during a movement
of the telescopic arm or fly jib, this may be in BASIC MODE
upon restarting the machine. In this case, fold the machine
completely, switch it off, and restart to re-initialise the machi-
ne.
NOTE : If lowering is carried out with the sealed electric safety pump,
refer to chap. 4.6.1, page 36.
3.2.9 - Range limits
The range limit indicator (orange) on the platform lectern is there for your
use as a visual indicator.
• This indicator flickers to indicate that the machine is executing a mo-
vement complementary to a required movement in order to keep the
platform within the limits of the stability zone. For example: the machi-
ne may retract the telescope when you ask for the fly jib to be lowered.
For extra safety, any accumulation of other movements is prohibited
during these phases. Lateral movement is prohibited within this zone.
• This indicator remains lit when the operator asks for a movement
which would make the platform extend beyond its working area. .
3.2.10 -Transport positioning control switch
This switch (control no. 12, Photo 1, page 27) located on the turret lectern/
panel when activated, allows the platform to be folded back under the fly
jib. It is active only when the arm is lowered, the fly jib retracted and raised
less than 5°. The platform must be empty of personnel and material when
this command is carried out.
