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
When using valves in compliance with Directive 2014/34/EU (ATEX) it is mandatory to
consult a specic manual.
It being understood that the essential characteristics of the type of control unit described herein

1 Safety, Warning and Mandatory Signs
EN-IST-GIOT360-1021
1.1 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.

EN-IST-GIOT360-1021
2 Safety
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 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.
• 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).

2 Safety
EN-IST-GIOT360-1021
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.
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 installation, use or maintenance which fails to comply
with the indications provided in this manual!

EN-IST-GIOT360-1021
3.1 Giotto Top electrical connections
4 Checking / Unpacking / Lifting
1. CHECK:
-Make sure the control unit shows no signs of damage caused during transport and that it corresponds
with the order;
2. UNPACKING:
The control unit packaging is made up of cardboard, wood and plastic.
The control unit is primarily made from plastic materials. The gaskets are usually made from elastomers.
Disposal must be in compliance with local legislation.
3. VALVE LIFTING:
Exercise caution when lifting the control unit.
.
WARNING!
Before lifting, make sure there are no disassembled or separate parts which could fall off causing injury
to persons and damage to the valve.
4. WAREHOUSING:
Avoid storing the control unit in a damp, dusty, wet or excessively hot place. Avoid areas subjected to
strong vibrations.
