proportional
coils after verification of the safety conditions by means of
the sensors positioned on the machine.
The control functioning on the circuit board can be by‑pas‑
sed by means of the key selector switch with spring return:
“safety device by‑pass key”.
The circuit board records every by‑pass action of the safety
devices by the operator, cataloguing them by date, time and
duration for which the operator has held the “safety device
by‑pass key” in position.
The board also records events that memorises all operations performed on the machine for a
variable period of time.
REDUCED STABILIZATION AREA
This type of machine is equipped with an additional electronic control board (see picture)
which analyzing the position of the outriggers and of the aerial part discerns the permitted
rotation area.
All the functions of the electronic board previously described for the standard version are
unchanged.
