2.0 - CPI SWITCH
2.1 - CPI SWITCH TECHNICAL DATA
• Ambient temperature
• Switchable voltage
• Switchable current
• Protection rating
2.2 - CPI SWITCH INSTALLATION and CALIBRATION
• black cable: common
• red cable: signal with micro switch not pressed
• white cable: signal with micro switch pressed
You must proceed as follows to install the CPI kit in on the solenoid valve:
DN 65 - DN 80 - DN 100 - DN 125 - DN 150 (see fig. 1):
• Loosen the fastening screw (1) inside the reset knob (2) and remove it;
• In the pin without the knob, insert the eccentric grub screw (8) with the larger part of the half moon on the left, and the new
knob supplied with the kit. The knob (2) must be inserted with the threaded hole facing up and making said threaded hole
match up with the pin hole. Secure the knob (2) by tightening and securing the grub screw (1) inside;
• Loosen the 2 screws (9) of the upper cover (11);
• Secure the upper cover (11) to the support bracket (7) of the micro switch using the 2 screws (9);
• Tighten or loosen the micro switch (5) for calibration so that when the solenoid valve is closed, the micro switch pin (4)
is pressed;
• Secure the micro switch (5) in that position by tightening the 2 threaded grub screws (6);
• The kit is now installed. Reset and close the solenoid valve (by cutting off the power) to make sure the microswitch is
signalling correctly. Repeat the operation 2-3 times;
• Position the protective cover of the knob (3) and secure it in that position with the screw (10).
