6.2 - CPI SWITCH INSTALLATION and CALIBRATION
It is necessary to close the gas prior to installation.
NOTE: CPI connector wiring (21) needs to be carried out taking
care to ensure the product's IP65 rating.
• Unscrew the cap (24) under the valve body (4);
• In place of the cap (24) screw in the CPI kit (23). Make
sure that between the body (4) and CPI kit (23) there is
the aluminium washer (18);
• Tighten the CPI kit (23) to the valve's body (4) with a special
commercial spanner;
• Before wiring the CPI connector (21), unscrew and remove
the central screw (20);
• Connect the CPI connector (21) terminals 1 and 2 in series
to the signalling device. Use the special cable terminals (see
the figures in 3.2);
• Wire the CPI connector (21) with a 2x1mm² cable having an
external Ø of 6.7 mm. The cable must have double sheathing,
be suitable for use outdoors, with minimum voltage of 500V,
and minimum temperature of 90°C;
• Secure the CPI connector (21), tightening (recommended
tightening torque 0.4 N.m ± 10%) the centre screw (20);
• To calibrate the microswitch, loosen the fastening nut (22)
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 (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.
9.0 - RATING PLATE DATA
