9.0 - RATING PLATE DATA
The user is obliged to keep the marking of the valve clearly visible: any coatings or
paintwork performed on the product that make the valve unidentifiable are not to be
attributed to the manufacturer.
The rating plate data (see example provided here) includes the following:
• Manufacturer’s name/logo and address (possible distributor name/logo)
• Mod.:
= name/model of the device followed by the diameter size
• CE-51CT4873
= certification pin number
• Cl. A
= Seal strength in counterflow at 150 mbar in accordance with EN 161
• Gr. 2
= Mechanical resistance group 2 in accordance with EN 161
• EN 161
= Product reference regulation
• P. max
= Maximum pressure at which product operation is guaranteed
• PS
= Allowable maximum pressure
• IP....
= Protection rating
• 230V....
= Power supply voltage, frequency (if Vac), followed by electrical absorption
• TS
= Temperature range within which product operation is guaranteed
•
=
Conformity with Regulation (EU) 2016/426 followed by Notified Body No.
•
(if it is present) = Conformity with PED Dir. followed by Notified Body No.
•
= In compliance with ATEX followed by the protection mode
(complete protection mode indicated on coil and CPI switch)
• year
= Year of manufacture
• Lot
= product serial number (see explanation below)
• U1737
= Lot issued in year 2017 in the 37th week
• 19491
= progressive job order number for the indicated year
• 00001
= progressive number referred to the quantity of the lot

6.2 - CPI SWITCH INSTALLATION and CALIBRATION
It is necessary to work in a non-explosive atmosphere
and shut off the gas before installation.
• ATTENTION:
The CPI switch is supplied with a 3 metre
long pre-wired connection cable. This cable
CANNOT
be
replaced with a different one. In the event of damage, the
part must be disposed of and replaced with an identical
new one; Any repair (if possible) can only be carried out
by the manufacturer;
• Unscrew the cap (
21
) under the valve body (
4
);
• In place of the cap (
21
) screw in the CPI kit (
15
). Make
sure that between the body (
4
) and CPI kit (
15
) there is
the aluminium washer (
20
);
• Tighten the CPI kit (
15
) to the valve’s body (
4
) with a special
commercial spanner;
• In the dangerous zone, wire the ends of the CPI cable with
explosion-proof approved equipment (E.g. Terminal box with
“E” protection or increased safety according to EN 60079-7)
using the special wire terminals;
• Connect the CPI cable (
16
) terminals in series to the
signalling device;
• To calibrate the microswitch, loosen the fastening nut (
19
)
and position (by screwing on or off) the adjustment ring nut
(
18
) so that, with the solenoid valve in a closed position,
the microswitch provides the signal;
• Secure the adjustment ring nut (
18
) in that position by
tightening the nut (
19
);
• The kit is now installed. Open and close the solenoid valve
(by supplying and cutting off power) 2-3 times to make sure
the microswitch is signalling correctly.
7.0 - TRANSPORT, STORAGE AND DISPOSAL
• During transport the material needs to be handled with care,
avoiding any impact or vibrations to the device;
• If the product has any surface treatments (ex. painting,
cataphoresis, etc) it must not be damaged during transport;
• The transport and storage temperatures must observe the
values provided on the rating plate;
• If the device is not installed immediately after delivery it must be
correctly placed in storage in a dry and clean place;
• In humid facilities, it is necessary to use driers or heating
to avoid condensation;
• At the end of its service life, the product is to be disposed of
in compliance with the legislation in force in the country where
this operation is performed.
