5.1 - REPLACING THE CONNECTOR
• Unscrew and remove the central screw (
13
), then remove the connector (
1
) from the coil (
11
);
• When you have taken out the existing internal electrical wiring, wire the new connector and secure it to the coil, as shown in 3.2;
5.2 - REPLACING THE COIL
• Unscrew and remove the central screw (
13
), then remove the connector (
1
) from the coil (
11
);
• 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
