If the coil and/or electronic board/connector need to be replaced:
• Before performing any operation, make sure that the device is not electrically powered;
• Since the coil is also suitable to be permanently powered, coil heating in case of continuous operation is an entirely
normal phenomenon. It is advisable to avoid touching the coil with bare hands after a continuous power supply lasting
longer than 20 minutes. In case of maintenance, wait for the coil to cool down or, if necessary, use suitable protections;
NOTE: if the coil (1) needs to be changed following an electrical failure, we recommend changing the connector (2) as
well. The coil and/or connector replacement operations need to be carried out taking care to ensure the product's IP65 rating.
6.1 - REPLACING THE CONNECTOR
• Fully unscrew and remove the central screw (3), then remove the connector (2) from the coil (1);
• 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;
6.2 - REPLACING THE COIL
• Fully unscrew and remove the central screw (3), then remove the connector (2) from the coil (1);
• Loosen the screw (17) that locks the coil (1) and take it out from the armature assembly (4) along with the gaskets/discs;
• Insert the new coil + seals + discs into the armature assembly (4) and secure everything with the screw;
• Couple the connector to the coil and secure it as shown in 3.2;
• If it is necessary to set up the wiring, proceed as described in 3.2
7.0 - CPI SWITCH
If the solenoid valve comes with CPI, the position of the micro switch is already calibrated and set, therefore, for operation you
simply need to connect it to the power supply. Follow the instructions in 7.2.
7.1 - CPI SWITCH TECHNICAL DATA
• Ambient temperature
• Switchable voltage
• Switchable current
• Protection rating
7.2 - CPI SWITCH CONNECTIONS and CALIBRATION
black cable: common - red cable: signal with micro switch not pressed - white cable: signal with micro switch pressed
If CPI calibration adjustments are required, it is possible to remove the threaded grub screw (19) and screw/unscrew the micro
switch (18). Then tighten the threaded grub screw (19) so that with the valve closed, the CPI provides the desired signal.
8.0 - 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 (e.g. 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 separately from other waste (WEEE directive 2012/19/EU)
and in compliance with the legislation in force in the country where this operation is performed.
