5.1 - REPLACING THE COIL
• Loosen the screw (or nut) (12) that locks the coil (11) and take it out from the armature assembly along with the seals/discs;
• Place the new coil + seals + discs inside the armature assembly and secure with the relative screw (or nut);
6.0 - CPI SWITCH
The microswitch that signals the closed position (CPI SWITCH) is a magnetic proximity sensor with normally open contact. It
provides a signal when the valve obturator closes.
If the solenoid valve comes with the microswitch, the position of the sensor is already calibrated and set; therefore, for operation
you simply need to connect it to the power supply.
If it comes separately and is installed at a later time on a solenoid valve with CPI set-up, follow the instructions provided in paragraph 6.2
6.1 - CPI SWITCH TECHNICAL DATA
• Ambient temperature
• Switchable voltage
• Switchable current
• Switchable power
• Resistance
• Protection rating
• Protection mode
• Cable length
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 (14) under the valve body (4);
• In place of the cap (14) 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 (18) terminals in series to the signalling device;
• To calibrate the microswitch, loosen the fastening nut (16) and position (by screwing on or off) the adjustment ring nut (19)
so that, with the solenoid valve in a closed position, the microswitch provides the signal;
• Secure the adjustment ring nut (19) in that position by tightening the nut (16);
• 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.
8.0 - WARRANTY
The warranty conditions agreed with the manufacturer at the time of the supply apply.
For damage caused by:
• Improper use of the device;
• Failure to observe the requirements described herein;
• Failure to observe the regulations pertaining to installation;
• Tampering, modification and use of non-original spare parts;
are not covered by the rights of the warranty or compensation for damage.
The warranty also excludes maintenance work, other manufacturers's assembling units, making changes to the device and
natural wear.
