1 Preliminary note 1.1 Symbols used ► Instruction > Reaction, result […] Designation of buttons, switches or indications → Cross-reference Important note Non-compliance can result in malfunctions or interference� 2 Safety instructions • Please read the product description prior to set-up of the unit� Ensure that the product is suitable for your application without any restrictions�...
3 Functions and features 3.1 Application area The unit monitors the flow of liquid and gaseous media� 3.2 Operating principle flow monitoring • The unit detects the flow speed to the calorimetric measuring principle and switches the output: - output closed if medium is flowing / output open if no medium is flowing� This applies to the unit on delivery: output = normally open�...
4 Installation Using process adapters the unit can be adapted to different process connections� • Adapters have to be ordered separately as accessories� A correct fit of the unit and ingress resistance of the connection are only en- sured using ifm adapters� • For small flow rates ifm adapter blocks are available�...
4.2 Sources of interference in the pipe system Components integrated in the pipes, bends, valves, reductions, etc� lead to turbu- lence of the medium� This affects the function of the unit� Recommendation: Adhere to the distances between sensor and sources of inter- ference: 5...10 x D 3...5 x D...
5 Electrical connection • The unit must be connected by a qualified electrician� • The national and international regulations for the installation of electrical equipment must be adhered to� • Caution: For the output circuit the same protective measures as • for the supply circuit must be taken�...
6 Operating and display elements Flow High 0 1 2 3 4 5 6 7 8 9 Setpoint 1: Operation display • The green LEDs indicate the current flow (the LEDs 0 to 9 represent the range between no flow and maximum flow)� • A lighting LED indicates the position of the switch point (orange = output closed, red = output open)�...
7.1 Change the switch point (optional) For the factory setting the switch point is at LED 7� A change makes sense in the folowing cases: • the display shows example 2� • the flow fluctuates much or pulsates� • a faster response time of the unit is requested (low switch point = fast response with rising flow, high switch point = fast response with falling flow)�...
8 Additional settings (optional) 8.1 Low flow adjustment If the unit is used in media other than water, you should additionally adapt the unit to the minimum flow� Note: The following adjustment must only be carried out after the high flow adjust- ment�...
► Press both setting pushbuttons simultaneously for at least 10 s in the operating mode� > The indication goes out, the unit locks or unlocks� On delivery: unlocked� 9 Error during adjustment If no adjustment is possible, all LEDs flash red� The unit then passes into the operating mode with unchanged values�...
10 Operation After every power on all LEDs light and go out again step by step (during this time the output is closed if configured as normally open)� The unit is then ready for operation� In case of power failure or interruption all settings remain� Operating indicators Green LED bar: Current flow within the representa- tion range�...
