- a turret control box:
Picture 11: emergency box.
o emergency button EB (Picture 11): this red and mushroom-
shaped switch blocks the machine by removing the power supply
to the control circuits. It has priority over any other command: it
makes possible only the manual emergency lowering of the ma-
chine on the ground.
The emergency button has an auto-detent mechanical locking
system; therefore, it is necessary to unlock the button turning it
clockwise to reset its operability.
o electric engine start button SB (Picture 11): pushing this red but-
ton the electric engine starts; pushing it again, the engine switches
off.
o electrical power supply indicator 8 (Picture 11): when the green
led is on, the PLE is electrically powered;
o stabilization consent light 9 (Picture 11): this red light, if
switched on, shows the consent to stabilize the machine;
o emergency bypass lever covered by a yellow cap (Picture 11 -
see par.4.6.2).
4 Use procedures
4.1 Environmental operating conditions
The equipment can work normally in the following environmental condi-
tions (for uses in different conditions, a special equipment is required):
• temperature from -20°C (-4°F) to +55°C (131°F)
(even +70°C (158°F) for short periods which do not exceed 24 h);
• humidity from 30% to 90% (at 20°C);
• max wind speed 12,5 m/s (45 Km/h - 27,96 mph).
Do not cover the equipment with cloths in order to avoid condensation
inside the electrical boards.
After storage in closed and very wet places for a long period, the ma-
chine could have some problems due to condensation in the electrical
boards: in this case, should this occur, please contact the C.M.C. Ser-
vice before use.
Do not work in areas with dangerous environmental conditions:
poor visibility, storms, lightning risk, etc.
Do not to work inside refrigerating rooms.
Do not work with the MEWP when the wind speed exceeds a
12,5 m/s (45 Km/h). We hereby enclose the Beaufort wind scale
(Table 1):
