Safety instructions 1. The installation, maintenance, initial operation, removal and repair has to be carried out by qualified experts with knowledge about electrical equipment and know-how about handling of pressure equipment and pneumatic pressure units. 2. The statutory and other applicable regulations and standards have to be noticed and kept. 3. Comply with the specifications on the data plate. 4. The pressure and temperature details given by the data plate have to be kept. 5. A fuse (with max. 4 A) has to be connected in series to the supply voltage of the control valve. 6. A pressure-reducing valve has to be installed in the control pressure supply line and it has to be set at the given control pressure. 7. The process pressure (delivery pressure) and the control pressure given by the type plate must not be exceeded. 8. Initial operation and pressure admission only when the silo filling device is completely installed. 9. When the silo filling device is damaged the compressed air and voltage supply has to be shut off immediately and it is to released from any pressure e.g. by removal of the control medium conveying line. 10. Any work at the filling device has to be carried out in pressure-free and de-energized condition only. ! 11. Read and follow the attached safety instructions for the single units. 12. By usage in explosive hazardous areas read and follow the enclosed safety instructions of the operating instructions and the explosive protection informations of the single units. 13. All product touching parts have to be made of stainless-steel if a) rust-containing particles (like rust film) are existent in the conveying medium and a gaseous explosive atmosphere is conveyed. b) combustible dusts with a minimum ignition energy less than 3 mJ or with a minimum ignition temperature below +300 °C (BAM procedure) are conveyed. 02 SFAQ-BA 02/22 © by MOLLET Operating instruction MOLLET D-74706 Osterburken Tel. +49 6291 6440-0 Fax +49 6291 9846 M LLET Füllstandtechnik GmbH Silo filling device SFA-Q Operating instructions 1. Specification 1.1 Extent of delivery Gasket Pinch valve Control valve (3/2-way solenoid valve) Protection tube Connection coupling Swivelling lever with limit switch Padlock with 2 keys 011-0200 Extent of delivery is depending on the choice of options. 1.2 Intended use The device is to be mounted at the filling pipe of silos, which were filled pneumatically by a silo vehicle, to connect the filling hose, for contacting and to shut-off the filling pipe. In its capacity as part of the silo filling device, the pinch valve is designed, build and approved as a ,,pressure-maintaining component" in accordance to the Pressure Equipment Directive 2014/68/EU. 1.3 Function The swivelling lever has to be swivelled aside to connect the filling hose to the coupling. The limit switch, which is integrated in the swivelling lever, signalizes to the control unit that a hose has been attached. The pinch valve will be actuated by compressed air via a control valve (Solenoid valve). The pinch valve is closed when deenergized. 1.4 Technical data Manufacturer MOLLET Füllstandtechnik GmbH Address Industriepark RIO 103 74706 Osterburken Name Silo filling device Type SFA-Q ...
