1501. Functions and features The flow monitor detects the flow velocity of water. Two switching outputs provide a signal if the respectively set flow velocity has been reached. In addition a row of LED’s indicates the current flow velocity.

• For pipes with nominal widths between DN 40 ... DN 100. Typical measurement errors for water and different temperatures of the medium.

• Min. 5 x pipe diameter upstream (A),

• min. 3 x pipe diameter down- stream (B). (This information refers to laminar flow.) Step 1 Weld the adapter into the pipe. The installation depth depends on the pipe wall thickness. The bush should be inserted so that the figure corresponding to the wall thickness is flush with the outside pipe wall and can be seen fromall sides. In the case of horizontal pipes the bush should be welded at an angle of 45°.

min. 5 x D min. 3 x DStep 2 Insert the flow monitor with lock nut, O-ring seal and compression washer into the bush and screw it in completely using the full thread. Step 3 Position the flow monitor (in the longitudinal pipe axis or trans- verse to it) and fasten the lock nut.

The national and international regulations for the installation of electrical equipment must be observed. Voltage supply to EN50178, SELV, PELV. The device shall be supplied from an isolating source and protected by an overcurrent device such that the limited voltage circuit requirements in accordance with UL 508 are met. Disconnect power before connecting the unit. Wiring: When the supply voltage is applied, all LEDs light and go off one after the other.* The unit is then ready for operation. *During this time both outputs are switched (= ON).

ENGLISH Core colours of ifm sockets: 1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4 = BK (black).

*Decrease the switch point: Let the flashing and lit LEDs move to the maximum setting value. Then the cycle starts again at the minimum setting value.

The current switch point is indicated in steps of 2% (here: 30 + 6 = 36 cm/s), after 5s the value is increased* (incremental by pressing briefly or scrolling by holding pressed). Here: 36 - 39 - 42 cm/s The set value becomes effective; the unit is reset to the operating mode. Press the button and keep it pressed (here setting of S1).

Press for a short time (= acknowledgement for S1).

LED green = last flow value indicated lit LED = 10% value of the switching point yellow (YE) = output switched; red (RD) = output not switched flashing LED = 2% value of the switching point

RDLocking/unlocking The unit can be electronically locked to prevent unwanted adjustment of the set parameters: Press both setting buttons for 10s. Indication goes out briefly (acknowledgement of locking / unlocking). Units are delivered from the factory in the unlocked state.

6. Installation and set-up / operation / maintenance

After mounting, wiring and setting check whether the unit operates correctly. When the supply voltage is applied, all LEDs light and go off one after the other.* The unit is then ready for operation. *During this time both outputs are switched (= ON). Indication in the operating mode Faults displayed during operation: 5 left LED’s flashing in case of short-circuit at the switching output S1; 5 right LED’s flashing in case of short-circuit at the switching output S2. 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.

ENGLISH LED’s green = current flow rate (here: 90 - 105 cm/s). 1st LED flashes = no flow

yellow LED = switch point / output switched here: output 1 switched

red LED = switch point / output not switched here: output 2 not switched
