Pneumax 2 SAFELI 412/2 Series Quick start guide

Descrizione prodotto: / Product description:
Elettrovalvole 3/2 N.C. versione 412/2 compatta con sistema di diagnostica dello stato della valvola. Consente di interrompere l’alimentazione e mettere in
scarico il circuito pneumatico dell’impianto d’installazione collegato alla porta 2, una volta che uno dei due, o entrambi i comandi elettropneumatici vengono
deenergizzati. Il sistema di diagnostica a doppio canale ridondante, legge la posizione della spola e di conseguenza rende noto lo stato delle valvole.
Solenoid valve 3/2 N.C. 412/2 compact version with diagnostic system indicating valve state. It allows to interrupt the power supply and to discharge the
pneumatic circuit of the installation system connected to port 2, once one or both of the electro-pneumatic controls are de-energized. The diagnostic system
reads the position of the spool and consequently takes note of the valve’s state.

• Se necessario montare i silenziatori sulle bocche di scarico.
• If necessary, mount the silencer on the exhaust port, where it was not installed.
• Alimentare elettricamente le bobine alla tensione nominale.
• Electrically supply the coil at the rated voltage.
• Alimentare elettricamente i sensori ad effetto di Hall e collegarli al sistema di diagnostica.
• Electrically power the Hall effect sensor and connect it to the diagnostic system.
• Alimentare pneumaticamente la sotto base.
• Pneumatically supply the base with air.

• with a de-energised coil, the sensor in ON status, OUT connection not under pressure.
• a bobine eccitate sensore in stato OFF, connessione OUT in pressione.
• with an energised coil, the sensor in OFF status, OUT connection under pressure.
Eseguire all’istallazione, prima di ogni utilizzo e periodicamente i controlli di corrispondenza dei segnali che mettono in relazione gli stati di ingressi e uscite:
Upon installation, before any use and periodically, determine the control of the signal correlations which compare the input and output states:
• STATO 0: alimentazione pneumatica/segnale elettrico assente
• STATE 0: pneumatic supply/electrical signal missing
• STATO 1: alimentazione pneumatica/segnale elettrico presente

utilizzare prodotti aggressivi o a base di alcool. Per operazioni di manutenzione su componenti interni si consiglia di rivolgersi a PNEUMAX SPA.
Before carrying out any operation, it is essential to remove the pneumatic and power supply to the device and wait for the residual pressure to be completely
discharged. Please ensure that the discharge is always clear, and in case a silencer is used, periodically verify that it is not obstructed. Periodically remove
any dust deposits from the valve using a damp cloth. Use soapy water to clean the device. Do not use corrosive or alcohol-based products. For maintenance
operations on internal components, please consult with PNEUMAX SPA.

Raccordare la bocca di scarico in modo che l’aria in scarico possa essere evacuata in una zona al di fuori dell’atmosfera potenzialmente esplosiva (in
particolare in presenza di polveri). Evitare di colpire le parti metalliche della valvola con oggetti metallici che potrebbero generare scintille di origine.

2014/34/EU ATEX DIRECTIVE - Notes for use in POTENTIALLY EXPLOSIVE environments
Connect the discharge port so that the discharge air can be evacuated to an area outside the potentially explosive atmosphere (particularly when there is
presence of dust). Avoid striking the metallic parts of the valve with metallic objects, which may generate sparks. Verify that the group of electrical construction
is appropriate to the gases and/or vapors present (the IIC group is suitable for any type of gas or vapor, in diverse mining installations).
Verify that the temperature class of the electrical construction is appropriate to the gases and/or vapors present in the installation area. Verify that the device´s

Special conditions of use (X): Please make sure that non-metallic parts are not subject to rubbing other parts in relative motion. These precautions are
also valid for other objects placed nearby and which may accumulate an electrostatic charge. Ground the metallic parts and limit the dimensions of the tubes
to Ø20mm. Do not rub and use damp cloths for cleaning. Protect the electrovalve island from direct impacts of more than 4J. To use in an environment with a
pollution level not higher than 2 (IEC 60664-1).
