2.1 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 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 unit, 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 machine installation, operation and maintenance.
• The J-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 J-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 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 was designed.
WARNING
The machine may not he used inside premises where there 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 connections are NOT active when executing operations
on the J-Giotto Top and that the power supply voltage is only 24 Vdc.

2 Safety
WARNING
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 secondary exposure due to their blinding effect. As also
occurs when looking at other bright light sources (such as vehicle high beams), there may be
a temporary reduction in visual acuity and afterimage which can cause irritation, discomfort,
eyesight issues and even injury, depending on the situation.
BARDIANI VALVOLE S.p.A. declines all liability for any
installation, use or maintenance which fails to comply with the
indications provided in this manual!

9 Disposal
9 Disposal
At the end of its service life, the device must be recycled in accordance with the legislation in force in the
country of valve use.
Any hazardous residues must be taken into consideration and adequately handled.
The control unit is made up of: elastomers (gaskets), plastic (control unit) and electrical components
(terminal board, solenoid valves, sensors).
Adhere to the following steps before disconnecting the valve and refer to the heading "General
Maintenance".
-Make sure the line on which the valve is installed in is not in use
-Disconnect the air supply
-Disconnect the electrical supply
-Remove the control unit from the valve
-To dismantle the control unit, refer to the heading "Disassembly"

10 Maintenance
10 Maintenance
1. PRECAUTIONS
When used correctly, the control unit does not need any special maintenance.
Any repair work must be carried out by authorized personnel only, making sure that the electrical and
pneumatic power supplies have been disconnected before carrying out any operation on the control unit.
Always make sure that the electrical and pneumatic connections are disconnected when carrying out
operations on the control unit.
2. REPLACING WORN PARTS
Should it be necessary to replace any component of the control unit, contact Bardiani Valvole S.p.A.
to purchase the necessary spare part as the use of any products not supplied by us may compromise
correct valve operation or constitute a hazard for personnel.
WARNING
Each time the casing is open, make sure that the various cables inside it are repositioned where they do
not interfere with cam movement.
2. SPARE PARTS:
Consult the spare parts manual to identify the part which needs replacing.
