Control parts related
to safety:
The control systems are designed and built in such a way
as to prevent the arising of hazardous situations. They are
designed and built so that :
they can withstand the intended operating stresses and
external influences
A fault in the hardware or the software of the control
system doesn’t lead to hazardous situations:
Errors in the logic of the control system do not lead to
hazardous situations
Reasonably foreseeable human error during
manoeuvring doesn’t lead to hazardous situations
;
The machine cannot start in an unexpected way
The machine parameters cannot have unchecked
modifications
It’s not possible to block the stop of the machine if the
stop command has already been given
No mobile element or held piece can be expelled during
the working cycle
Manual or automatic stop of any kind of mobile element
is not hampered,
The protection devices must remain completely efficient
or give a stop command to the operative cycle,
The parts of the control system that are related to
security are applied in a coherent way inside the
machine.
Electrical Hazard:
Differential switch
Direct
and
indirect electrical
contacts
Protection against
overcurrent
The machine is powered by electricity, it is designed,
constructed and equipped in such a way as to prevent or
to permit to prevent all electrical hazards The electrical
system has been designed in accordance with Technical
Standard EN 60204-1. The plant is equipped with a
differential switch with threshold of protection of 30 mA
on the supply machine of the machine.
Electrical hazards:
Ground connections
Direct
and
indirect electrical
contacts
Protection against
overcurrent
On the system an appropriate protective equipotential
circuit, which includes:
The conductive structural parts of the electrical
equipment and of the machine.
The protective conductors in the equipment of the
machine
The plant has been designed in accordance with
Technical Standard EN 60204-1.
Lighting:
Lighting work areas of
the machine
Dazzling
The machine is equipped with a lighting device placed
inside the electrical cabinet, for any maintenance
operation. The machine is also realised in such a way so
that there is no shadow zone that can cause disturbing,
no irritating dazzle, no dangerous stroboscopic effects on
the moving parts.
Heat hazards:

Burn and scald
hazard for direct
contact with hot
parts
in
the
packaging area.
All elements that reach dangerous temperatures have
been protected and placed in non-accessible areas.
Signs have been placed to signal the areas that reach
high temperature. Always use protective gloves before
any intervention intended to remove any possible
stoppage in the system.

parts conveyed
on the system
The elements processed on the system reach dangerous
temperatures (Dry ice T = - 80 °C).
Signs have been placed to signal the dangerous areas.
Always use protective gloves.
