First Start-Up - Madas M16/RM N.C. EEX Manual Del Usario

4.0 - MANUAL RESET (see fig.1, 2, 3 and 4)
To reset the solenoid valve:
• Make sure there is power;
• Close the flow downstream of the solenoid valve in order to balance the pressure between upstream and downstream when opening;
• Loosen and remove the protective cover (7);
• Fully press the reset pin (8) and wait a few seconds for the pressure upstream and downstream of the valve to stabilise until
it locks into place;
• Screw the protective cover (7) back on in its original place. Or seal it in that position.

5.0 - FIRST START-UP

• Before start-up make sure that all of the instructions on the rating plate, including the direction of flow, are observed;
• After having gradually pressurised the system, reset the solenoid valve, as indicated in 4.0;
• Check the tightness, the operation and the closing of the solenoid valve, electrically disconnecting.
5.1 - RECOMMENDED PERIODIC CHECKS
• Use a suitable calibration 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;
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.
6.0 - MAINTENANCE
No maintenance operations need to be carried out inside the device.
On completion of the operations described below, repeat the procedure indicated in paragraph 5.
If the coil 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;
6.1 - COIL REPLACEMENT (see figure on the side)
• Disconnect the coil's power supply cable, requiring replacement, from the system;
• Use a size 14 commercial spanner to loosen the nut (15) completely and remove
it together with the washer (19);
• Remove the coil (1) from the armature assembly (2);
• Insert the armature assembly: the new coil + washer + nut;
• Tighten the nut (max torque = 1,2 Nm);
• Re-wire as indicated in 3.2;
