inside of the machine body where the dough dividing and rounding process takes place. It is an interlocked
door, which can be opened to the left as it is hinged to the machine body on its left side. The internal
components move inside it. This is a sturdy and rigid door, equipped with a solid handle for easy opening. If
the door is opened by more than 2 mm while the machine is running, the safety system commands the
emergency stop of the machine, which takes place in a very short time (fraction of a second) . To restart the
working components, it is first necessary to completely close the door, then press the RESET button
indicated with ref. 1 in Figure 5 . In the case of “SYNCRO” and “SYNCRO M”, the door is double, one on the
left hinged on its left side, and the other on the right, hinged on its right side. “SYNCRO E” and “SYNCRO
EM”, instead, feature a single door opening to the left.
3. Rear door associated with a mechanical safety microswitch: Figure 13 ref. 5. It allows accessing the
rear part of the machine body which contains the part of the machine suitable for generating the movements
of the components dedicated to processing the dough (which take place in the front part accessible from the
front door). In the rear area there are several gearmotors, proximity sensors, movement transmission
devices, which do not come into contact with the food product, but which must be cleaned from time to time
to remove the layer of flour dust that can settle, especially if a lot of flour is used during dough processing. In
both construction versions, a key safety microswitch stops the machine immediately if the key (fixed to the
door) is removed from the limit switch (fixed to the body of the machine). To restart the working components,
it is first necessary to completely close the door, then press the RESET button indicated with ref. 1 in Figure
5 . The opening of the door causes the machine to stop in emergency mode when the maximum distance on
its upper edge between the door and the machine body is 4 mm.
4. Mobile sliding guard applied to the loaf moulder: Figure 13 ref. 3, only for “SYNCRO M” and “SYNCRO
EM”. It allows accessing the upper area of the loaf moulder, which is useful for example to remove irregular
portions of dough that may have built-up during the working day. It consists of a horizontal surface that slides
horizontally on guides and supports the flour duster. It is associated with a key safety microswitch which
immediately stops the machine when it is opened by more than 2 mm. To restart the working components, it
is first necessary to completely close the door, then press the RESET button indicated with ref. 1 inFigure 5 .
5. Mobile safety bar at dough outfeed (only for “SYNCRO” e “SYNCRO E”): Figure 13 ref. 6. It consists of
a bar, pivoted at its base so that it can rotate in the event of pressure in both directions on the output axis of
the dough. It is associated with a mechanical limit switch. It is installed at the outlet of the product unloading
belt and it immediately stops the machine in emergency mode even if a slight pressure is exerted such as to
generate a small rotation around its fulcrum. In addition to this safety bar, there are some moving parts
dedicated to the correct unloading of the dough onto the transfer belt. To restart the working components, it
is first necessary to release said mobile bar so that it immediately returns to its resting position; then press
the RESET button indicated with ref. 1 in Figure 5 . The emergency stop of the machine takes place at a
pressure of 5 N (approx 0.5 kgf) generating a horizontal displacement of the bar of 5 mm.
6. Emergency stop push-button; indicated with ref. 2 in Figure 5 and ref. 2 in Figure 5. When pressed, it
stops any moving part and cuts off the power supply to all the components that may otherwise be
dangerous. Once pressed, it is mechanically held in such condition and can only be reset with a voluntary
action. To restart the machine, first reset the push-button, then restore standard operating conditions by
pressing the "RESET" button indicated as ref. 1 in Figure 5.
7. Fixed guards: these are guards held in place by elements that cannot be removed or opened, except by
using a tool (wrenches for screws, keys for locks, etc.) as an alternative to the mobile interlocked guards
illustrated in points 2, 3 and 4; they inhibit access to most of the movable working and motion transmission
parts. In practical terms, the internal components of the machine are segregated by fixed guards, which are
associated with interlocked removable guards and/or the safety devices illustrated in the previous points.
The electric box is also a fixed guard
ATTENTION!
It is prohibited to remove the guards and/or deactivate safety devices unless for real and unavoidable
reasons, provided that measures aimed at eliminating or minimising correlated risks have been adopted, and
that express authorisation of the employer, manager, supervisor, etc. has been obtained. Put back the guards
and lock them in place using all the required means and re-activate the safety devices as soon as the
reasons for their removal / deactivation have ceased. Anyone who does not comply with the instructions above
will be held fully liable for any and all direct or indirect injury to persons or animals and damage to property that
may occur.
5.2.3 CHECKING THE EFFICIENCY OF SAFETY DEVICES
At the beginning of the day and/or shift, check the efficiency and condition of the safety devices illustrated in
par. 5.2.2:
1. Check the efficiency of the light curtain installed on the hopper Carry out the test without dough in the
