INTRODUCTION This “Instruction, Use and Maintenance Manual” has been drawn up expressly for expert technical personnel. Consequently any information which can easily be deducted from reading the text and/or examining the illustrations and/or drawings provided herein shall not be the object of further explanation. This “Instruction, Use and Maintenance Manual” forms an integral part of the control unit. Before proceeding with installation, use or maintenance of each type of control unit it is compulsory to read and understand this manual. This manual must be kept for all future reference...

Special instructions must be followed to avoid injury to persons. Dismantling/Assembling and maintenance operations must be carried out by expert technicians only....

Safety, Warning and Mandatory Signs Operator training All persons who have to work on the valve must be qualified to carry out the relative maintenance tasks. They must be informed as to the possible hazards involved and must observe all the safety instructions set out in this manual. Allow expert personnel only to work on the electrical components.

General safety warnings 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...

WARNING The control unit contains circuits classified as LOW VOLTAGE LIMITED ENERGY CIRCUIT. For correct use in North America dimension the protection circuits in accordance with Standard UL508A. WARNING ALWAYS make sure the electrical and pneumatic connections are NOT active when executing operations on the Giotto Top and that the power supply voltage is only 24 Vdc. Under normal circumstances (exposure time, eye pupils, viewing distance) it is assumed that the LEDs do not present any danger to eyes. In principle, however, please remember that intense light sources have a high potential of...
