8.1. Cabin was raised too high
The end travel detector " final switch" (LS15) of the platform may reach the "superior
EXTREME" limit rail if:
• The " stop UP" (LS5) travel end runner or detector is incorrectly adjusted.
• There is a defect in the electrical system.
Emergency mesures:
• Use the emergency descent procedure to lower the platfom. Lower until the runner is
cleared. (SEE SECTION 7.13 EMERGENCY DESCENT PROCEDURE, ON PAGE 59)
o Note: if the travel end detector in blocked despite absence of contact with the runner,
the safety line remains triggered. Lower the unit to ground level to work safely.
• The cabin now moves out of the "superior EXTREME" travel end position.
• Identify the source of the problem and apply necessary corrections.
8.2. Cabin was lowered too low
The end travel detector " final switch" (LS15) of the platform may reach the "inferior
EXTREME" limit rail if:
• Air clearance of the engine brakes is too big.
• The "stop DOWN" (LS6) travel end runner or detector is faulty.
• There is a defect in the electrical system.
• The cabin in overloaded.
Emergency mesures:
• connect the derivation adaptor (ITEM RD-7243-BE-112, SEE CENTRIFUGAL EMERGENCY BRAKE
ACTIVATION, ON PAGE 60) in the port of the panel (CC1).
• On the operator control box (CC2), the white "HAUT/UP" button lights up, meaning the
control is available. Press and maintain the button to elevate the platform (automatic stop
after 5 seconds). Press again until the runner is cleared.
• The cabin now moves out of the "inferior EXTREME" travel end position.
• Identify the source of the problem and apply necessary corrections.
8.3. The overload warning device was triggered
(optional equipment only).
The platform is equipped with an overload warning device (optional) that prevents start-up when
the cabin is overloaded. If the cabin is overloaded, a red indicator light lights up on the main
power supply box.
WARNING!
If the indicator light in on, reduce the load on the platform until the indicator light turns off. Only
then will it be possible to start and move the platform.
NOTE
For more information on the prevention of overloads, consult the overload protection device
manual.
