EN 61000-4-6 3 V; 0,15 ... 80 MHzFunction and features The flow monitor monitors liquid media. It senses whether there is a preset flow (= medium flows) or not (= medium does not flow) and provides a switching signal.
- For use in T-pieces to DIN 2353. Installation Insert the unit into the T-piece (1) and orientate it. Fasten the nut (2); always keep the unit in its orientation. To avoid malfunction a minimum distance between the flow mon- itor and bends, valves or such like must be observed (fig. 3).
- Min. 5 x pipe diameter upstream,
- Min. 3 x pipe diameter down- stream.
min. 5 x D min. 3 x D7 ENGLISH Electrical connection The unit must only be mounted by an electrician. The national and international regulations for the installation of electrical equipment must be observed. Voltage supply for units up to 60 V to EN50178, SELV, PELV. Disconnect power before connecting the unit. Wiring diagramm: Core colours of ifm sockets: 1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4 = BK (black).
1. Apply the operating voltage. Switch on the flow (preset value) and

If necessary, build-up which adheres firmly (e.g. lime) can be removed with a common vinegar cleansing agent. The units are suitable for use in moderate electromagnetic fields (see table). When operating ISM equipment or powerful walkie-talkies in the vicinity of the units additional measures to avoid malfunction can be required.
