First Start-Up - Madas EVPF/NC Manual Del Usuario

• Wire the connector (30) with a 3x0.75mm² cable with external Ø 6.2 to 8.1 mm. The cable must feature a double sheath,
suitable for outdoor use, with a minimum voltage of 500V and a temperature of at least 90°C;
• Connect terminals 1 (L) and 2 (N) to the power supply and the earth cable to the terminal
"SOLENOID VALVE POWER" (see diagram 1 - fig. 5). IMPORTANT: respect the polarity with 24 Vdc power supplies:
(normal connectors: pin1 connector =
• Secure the connector (30) by tightening (recommended tightening torque 0.4 N.m ± 10%) the centre screw (32);
• The valve needs to be earthed either through the pipe or through other means (e.g. cable jumpers).
3.3 - INSTALLATION IN PLACES WHERE THERE IS THE RISK OF EXPLOSION (DIRECTIVE 2014/34/EU)
The solenoid valve is not suitable for use in potentially explosive areas.

4.0 - FIRST START-UP

• Before start-up make sure that all of the instructions on the rating plate, including the direction of flow, are
observed;
• IMPORTANT: During the first start-up, energise the valve electrically for about 15-20 seconds and de-energise
it. Repeat the step at least 4-5 times to ensure the Air and Oil inside the hydraulic circuit are separated.
• After having gradually pressurised the plant, check the tightness and operation of the solenoid valve by supplying/
cutting off the power.
4.1 - RECOMMENDED PERIODIC CHECKS
• Use a suitable calibrated tool to ensure the bolts are tightened as indicated in 3.2;
• Check the tightness of the flanged/threaded connections on the system;
• Check the tightness and operation of the solenoid valve;
The final user or installer is responsible for defining the frequency of these checks based on the severity of the service conditions.
