Intended Use
The control unit has been designed to control the pneumatically controlled process valves
manufactured by Bardiani Valvole S.p.A..
It is possible to fit the Giotto Top with a maximum of three solenoid valves for controlling the process valve
and up to a maximum of four inductive sensors, including an external one for controlling the position.
For the electrical connections inside the control unit, there are three different configurations:
• LED terminal block and As-i card: the LEDs indicate, in the presence of the relative inductive sensor,
the status of the valve: green light = valve open; yellow light = valve closed; white light = bottom or top
lift activated.
• 10-pole terminal block: no LEDs.
General warnings
• Always read the technical data carefully before machine installation, operation and maintenance.
• The Giotto Top must always be installed, operated and maintained by authorized personnel. Said
personnel must know and understand both the unit and the contents of the manual.
• Take care over any separate parts of the Giotto Top when removing it from its packaging.
• Always connect the air supply carefully and disconnect it after use.
• Always connect the power supply carefully and disconnect it after use.
• Never touch the moving parts in the Giotto Top or valves.
