(see figure on the side)
Refer to the technical manual regarding CPI micro switch.
For protection mode see the solenoid valve instruction IT347.
2.2 - CPI SWITCH INSTALLATION and CALIBRATION
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 (11) inside the reset knob (1) and remove it;
• In the pin without the knob, insert the eccentric grub screw (2) with the larger part of
the half moon on the left, and the new knob supplied with the kit. The knob (1) must be
inserted with the threaded hole facing up and making said threaded hole match up with
the pin hole. Secure the knob (1) by tightening and securing the grub screw (11) inside;
• Loosen the 2 screws (9) of the upper cover (12);
• Secure the upper cover (12) to the support bracket (7) of the micro switch using the 2 screws (9);
• For calibration, change the position of the microswitch from the 2 screws (4) and 2 nuts (6) so that when the solenoid valve
is closed, the micro switch's pin (3) is pressed;
• Secure the micro switch (5) in that position by tightening the 2 nuts (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 cover of the knob (8) and secure it in that position with the screw (10).
