5.2.1 Main key switch / control station selector.
The main key of the ground control station is used to:
- Switch on the machine by selecting one of the two control stations:
- Control station on the platform with the key turned on the BLUE frame. Stable position with
the possibility of extracting the key (for machines commissioned outside Europe it is possible
that in this position the key cannot be removed);
- Ground control station with the key turned to PURPLE box. Stable position with non-
removable key.
- Switch off the control circuits by turning the key to position “0”. Stable position with the possibility
of extracting the key.
Attention: The master key must always be available to the recovery worker who remains on the ground
during normal use of the machine, ready to intervene in the event of an emergency.
At the end of the work, turn off the machine by turning the main key to position "0" and remove the key
itself in order to avoid unauthorized use of the machine.
5.2.2 ON / OFF selector / Preheating of thermal and electric engines / ENABLE
function.
This selector turns on / activates the motor needed to power the hydraulic control circuits.
- To start the internal combustion / electric engine, select ON;
- To switch off the internal combustion / electric engine, select OFF;
Once the engine has been turned on, to enable the movement switches of the extensible structure, the
switch must be activated in advance and kept in the ON position for the entire duration of the movement.
Releasing the switch, the command stops.
NOTE:
- By selecting and keeping the selector in OFF, the preheating glow plugs of the internal combustion
engine are activated (keep the command for about 10 seconds);
- If the machine is connected to the mains, the electric motor is activated (if present); otherwise,
the internal combustion engine starts up.
- With the machine powered by an electric motor, if no signal is received after 5 minutes, the electric
motor switches off.
