Solenoid valves
6.3.1 Motor-pump assembly
Electrical motor and pump are connected by an elastic coupling.
6.3.2 Oil reservoir
It is in the machine frame, and it has a maximum and a minimum level indicators, and a suction filter. On the left side of the
infeed roller table there is a plug which allows to refill the reservoir. The hydraulic system has 2 filters :
•
a 250 micron 45 liters suction filter
•
a 60 micron 45 liters outflow filter
These two filters have to be removed when changing the oil for the first time (after 500 working hours), washed using tri-
chloroethylene and dried blowing air.
6.3.3 Solenoid valves
The solenoid valves are mounted on blocks, and the control the hydraulic movements.

LECTRICAL SYSTEM
6.4.1 Control console
The control console is on the upper part of the control enclosure, and all the push-buttons and switches are mounted on it.
There is a 5” monitor, which displays the control commands.
6.4.2 Control enclosure
It is made bending metal sheets and it complies the IP55 standards. Inside there is the electrical panel which supports all the
electrical devices (relays, circuit breakers,...) complying the CEI 60204.1 standards.
