6. Instruction, Use and Maintenance Manual GB-IST-JGIOT360-0419 2 General safety warnings The control unit has been designed to control the pneuma tically controlled process valves manufactured by Bardiani Valvole S.p.A.. It is possible to fit the J- Giotto Top® with a maximum of two solenoid valves for controlling the process valve and up to a maximum of two inductive sensors for controlling the position. For the electrical connections inside the control un it, there are two different configurations: • LED terminal block: the LEDs indicate, in the presence of the relative inductive sensor, the status of the valve: green light = valve open; yellow light = valve closed. • 10-pole terminal block: no LEDs. General warnings • Always read the technical data carefully before mach ine installation, operation and maintenance. • The J-Giotto Top ® must always be installed, operated and maintained by auth orized personnel. Said personnel must know and understand both the unit and the contents of the manual. • Take care over any separate parts of the J-Giotto T op ® when removing it from its packaging. • Always connect the air supply carefully and disconnec t it after use. • Always connect the power supply carefully and disconne ct it after use. • Never touch the moving parts in the J-Giotto Top ® or valves. • Always handle detergents with care. Prohibited use Use of the control unit is not envisaged: • for any operations other than those for which it w as designed. WARNING The machine may not he used inside premises where ther e is a potentially explosive atmosphere or risk of fire unless otherwise stated by the manufacturer ( in the case of valves certified in accordance with Directive 2014/34/EU please refer to the ATEX Manual) . 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 connect ions are NOT active when executing operations on the J-Giotto Top® and that the power supply voltage is only 24 Vdc. BARDIANI VALVOLE S.p.A. declines all liability for installation, use or maintenance which fails to comply with the indications provided in this manual! 6
