1 Function and features The flow monitor monitors liquid media. It senses whether there is a preset flow and provides a switching signal. • The switch point can be set: 10...60 cm/s in steps of 5 cm/s). This value is valid for water and installation in pipes 4".
To avoid malfunction a minimum distance between the flow monitor and bends, valves, changes in cross-section or such like must min. 3 x D be observed: • Min. 5 x pipe diameter upstream (A). min. 5 x D • Min. 3 x pipe diameter downstream (B).
The maximum current rating must not be exceeded. Even if it is exceeded for a short time the unit is destroyed. 4 Switch point setting Apply the operating voltage (+UB) to pin 2 for the specified time. IN (Pin 2) OUT = 1 OUT = 0 Time window...
5 Operation ► After mountingand wiring check whether the unit operates correctly. Recommended maintenance: ► Check the sensor tip for build-up from time to time. Clean it with a soft cloth. If necessary, build-up which adheres firmly (e.g. lime) can be removed with a common vinegar cleansing agent.
