Preliminary note • An instruction is indicated by “►”: Example: ► Check whether the unit operates correctly. • A reaction to the action is indicated by ">": Example: > LED 9 lights. 1 Safety instructions • Please read the product description prior to set-up of the unit. Ensure that the UK product is suitable for your application without any restrictions. • The unit conforms to the relevant regulations and EC directives.
2 Functions and features 2.1 Application area The unit monitors the flow of liquid and gaseous media. 2.2 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. In case of need you can change the output to normally closed (→ 7.2). It then applies: output open if medium is flowing.
3 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 ensured using ifm adapters. • For small flow rates ifm adapter blocks are available. 3.1 Installation location General • The sensor tip is to be completely surrounded by the medium. • Insertion depth of the sensor: minimum 12 mm.
3.2 Sources of interference in the pipe system Components integrated in the pipes, bends, valves, reductions, etc. lead to turbulence of the medium. This affects the function of the unit. Recommendation: Adhere to the distances between sensor and sources of interference: D = pipe diameter; S = sources of interference 3.3.
4 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. Voltage supply to EN 50178, SELV, PELV. ►► Disconnect power.
6 Set-up and settings for water (For media other than water → 7.1: Low flow adjustment). ►► Switch on the supply voltage. >> 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 in the operating mode. ►► Let the normal flow circulate in the installation. ►► Check the display and determine further actions.
6.2 High flow adjustment (optional) The unit determines the existing flow as normal flow and adapts the display representation (all LEDs except the switch point LED light green). ►► Let the normal flow circulate in the installation. and keep it pressed. ►► Press the pushbutton >> LED 9 lights, after approx. 5 s it flashes. ►► Release the pushbutton. The unit is now adapted to your flow conditions. It passes into the operating mode, the display should now show example 1.
7.3 Restore the factory setting (reset) ►► Press the pushbutton for at least 15 s. >> LED 9 lights, after approx. 5 s it flashes. >> After approx. 15 s LEDs 0...9 flash orange. ►► Release the pushbutton. All settings are reset to the factory setting: -- operating area: 5 ...100 cm/s for water -- switch point: LED 7 -- output function: NO -- unlocked. 7.4 Lock / unlock the unit The unit can be locked electronically to prevent unintentional settings.
9 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 representation range. Indication of the switch point (SP): UK - LED orange: output closed. - LED red: output open.
