6.0 - CPI SWITCH
The microswitch that signals the closed position (CPI SWITCH) is a magnetic proximity sensor with a normally open contact. It
provides a signal when the valve obturator closes.
If the solenoid valve comes with CPI, 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
• Cable length
6.2 - CPI SWITCH INSTALLATION and CALIBRATION (fig. 6 and 7)
It is necessary to close the gas prior to installation.
NOTE: CPI connector (23) wiring must be do ensuring a product rating of IP65;
• Remove the cap (11) under the valve body (7) and remove the aluminium washer (found between the cap and body);
• Instead of the cap (11), tighten the CPI ring nut kit (21). Make sure that between body (7) and kit (21) there is the new
aluminium washer or an O-Ring (25);
• Tighten the CPI ring nut kit (21) to the valve's body (7) with a special commercial spanner;
• Before wiring the CPI connector (23), unscrew and remove the central screw (34);
• Connect the CPI connector (23) terminals 1 and 2 in series to the signalling device. Use proper cable terminals (see the
figures in 3.2);
• Wire the CPI connector (23) with 2x1mm² cable with external Ø of 6.7 mm. The cable must be in double sheath, suitable
for outdoor use, with a minimum voltage of 500V and a temperature of at least 90°C;
• Secure the CPI connector (23), tightening (recommended tightening torque 0.4 N.m ± 10%) the centre screw (34);
• To calibrate the microswitch, loosen the fastening nut (22) and position (by screwing on or off) the adjustment ring nut (24)
so that, with the solenoid valve in a closed position, the CPI provides the signal;
• Secure the adjustment ring nut (24) in that position by tightening the nut (22);
• 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.
