1.7.1 Safety devices of the electrical equipment – Wiring diagram
The electrical circuits of the machine, the wiring diagram, the buttons, the switches and
the selectors are all designed and manufactured in conformity with the specific
standards
To preserve safety:
The electrical system that supplies the auxiliary circuits is powered by a low
voltage transformer (IEC 96-2).
A specific micro-switch with forced opening of contacts blocks operation at the
moment the protection of the rotating bowl (cover) is lifted
A specific micro-switch with forced opening of contacts blocks operation at the
moment the head is lifted.
An interface circuit between the command and the power ones prevents the
spontaneous restart after a voltage reduction or after the interruption of the
supply voltage, by making indispensable the voluntary reset intervention of
the machine operation circuit.
The electrical appliances and the circuit are inserted in the corresponding
containers with IP 55 protection level.
The wiring diagram has been carried out according to the standard instructions related
to the electric equipments of industrial
machines.
There is a copy of the wiring diagram in the appendix of this manual.
1.7.2 Safety devices of the mechanical equipment
In order to obtain the maximum degree of safety and reliability, the mechanical safety
devices are integrated to the structure of the machine and can’t be violated:
The cover of the bowl allowing the introduction of water without lifting it or
interrupting the system operation.
A vertical polycarbonate protective glass, permanently fixed to the bowl,
prevents that hands, fingers and other parts of the body get crushed or
trapped between the kneading column and the bowl.
Keep hands, arms or any other part of the body away from the
rotating bowl or the moving parts inside it.
Do not remove the rear or upper crankcase, or the polycarbonate
protection during machine operation.
