6.2 LOAD CONTROL
When the permissible load on the work platform
is exceeded, the corresponding lights on the
control stations flash, an alarm sounds, and all
the movements are stopped. The platform must
be partially discharged until the alarm stops.
-NOTE-
If the overload was triggered by a collision with an overhead obstacle, it is possible to
clear the machine by neutralising momentarily the load control device. Refer 7.2 -
Neutralisation of safety devices.
6.3 SYSTEM FAULT
The system fault light comes on when the control
system detects a defect on one of the
components or an operating fault.
Depending on the importance of the fault for the
safe use of the machine, the system authorises
the operation of certain controls in degraded
mode or completely disables the use of the
machine.
The exact nature of the fault is indicated on the
control module screen: Refer to Section 9.
The machine's operation is restored when the fault disappears or after the emergency stop is
cycled again (depending on the nature of the fault).
In any case, the machine's use must be interrupted until the fault is corrected. After repair, a full
check of the operation of the machine and the safety mechanisms must be carried out by a
qualified person before the machine is returned into service.
If a fault occurs when the platform is raised and is occupied by personnel, appropriate
measures must be taken to rescue the platform's occupants.
6.4 MOVEMENT ALARMS
A movement alarm may sound:
- During drive movements
- During lifting structure movements
- During drive and lifting structure movements
Refer to Section 9 – Control screen.
An optional flashing light may be fitted to the machine.
This equipment may be activated:
- On power up
- When the combustion engine is running
- During drive movements
- During drive and elevating structure movements.
Refer to Section 9 – Control screen.
