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 calibration tool to ensure the bolts are tightened as indicated in 3.2;
• Check tightness of the flanged/threaded connections on the system;
• Check tightness and operation of the solenoid valve;
• Pulire regolarmente il prodotto per evitare accumuli di polvere;
• E' fondamentale annullare il rischio di innesco causato da correnti vaganti o qualsiasi condizione di differenza di potenziale
tra i dispositivi presenti sull'impianto. Verificare periodicamente che sussista una buona conduzione elettrica tra corpo
valvola e linea di equipotenziale di impianto e tra bobina e linea di equipotenziale di impianto.
It is the responsibility of the final user or installer to define the frequency of these checks based on the severity of the service
conditions.
4.2 - ADJUSTMENTS (XVF/NC models)
• The flow adjustment must be done in the absence of an explosive atmosphere with the system stopped and the
valve NOT electrically powered. It is recommended to wait for the actuator to cool down (if previously powered)
and/or to use suitable thermal protection for hands;
• Unscrew the fastening screw (17) and move the protective casing upwards (6) into the position shown in fig. 1.
• Loosen the screw (18) and move the switch (19) by sliding it along its pin. The more the switch is moved upwards, the more
the max flow of the solenoid valve is limited. Once the switch (19) has been set in place, secure the position by tightening
the screw (18). The setting range is marked with the min and max indications.
• IMPORTANT: verify that the switch de-energises the pump at the set position.
