5.1.4.1. SENTINEL control logic
When the operator is crushed against the BUMPER ( a ), in addition to what described in the previous paragraph, all the current
operations automatically react as follow:
- Drive with lifted platform (safety speed): the current operation is immediately stopped and reversed;
- Drive with lowered platform (at any speed) : the current operation stops slowly.
- All the extensible structure operations (lifting, lowering, rotation) individually or simultaneously activated except
for the pantograph lowering and the telescopic retraction: the current operation is immediately stopped and
reversed;
- Pantograph lowering, Telescopic retraction and Cage Levelling Correction: the current operation is immediately
stopped.
3 seconds after the operator hits against BUMPER ( a ), the control foot pedal is automatically deactivated regardless of the
joystick control, the green pilot on the platform control panel starts flashing, and you must first release and reactivate the foot
pedal in order to enable the other controls on the platform control panel.
The ground control panel is always available for the emergency recovery of the operator possibly trapped, in any condition of
the SENTINEL system.
