ENGLISH

• In the case of horizontal pipes mount the unit from the side, if pos- sible (fig. 1). When the unit is to be mounted at the bottom of the pipe, it should be free from deposits. When the unit is to be mounted at the top of the pipe, it should be completely filled with the medium to be monitored.

• In the case of vertical pipes mount the unit in a place where the medium flows upwards (fig. 2). To avoid malfunction a minimum distance between the flow mon- itor and bends, valves, changes in cross-section or such like must be observed:

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

31. Lubricate the nut (3) and all threads with grease to ensure the nut

can be loosened and tightened several times. Note: No grease must be applied to the sensor tip (A).

2. Screw the suitable adapter (2) onto the process fitting (1).

3. Insert the flow monitor into the adapter. While keeping the unit

aligned tighten the nut (3); (max. tightening torque 50Nm). Insertion depth of the sensor: min. 12mm in the pipe. When the adapters are used which are available as accessories, the correct depth is ensured. Note: The sensor tip must not touch the pipe wall. ENGLISH

Setting of the switch points (SP1 / SP2)

• Press the Mode/Enter button briefly (to set SP1), or press the Mode/Enter button twice (to set SP2).

• Press the Learn/Set button for 5s,

• keep the Learn/Set button pressed or press the button several times until the requested switch point is set.

• Press the Mode/Enter button briefly.

Monitoring excess flow

• Press the Mode/Enter button three times.

• Press the Learn/Set button for 5s, release the button when LED flashes.

• Press the Learn/Set button several times to shift the LED for the maximum display value.

• Press the Mode/Enter button briefly.

Reset to factory settings

• Press the Learn/Set button for >15...<20s

Programming■■ The following applies to all setting procedures:

• If no button is pressed for 15s during the setting procedure, the unit returns to the operating mode with the parameter values unchanged.

• If adjustment has not been possible, all the red LEDs flash. The unit returns to the operating mode with the parameter values unchanged.

Locking / Unlocking The unit can be electronically locked to prevent unwanted adjustment of the set parameters: Press both setting buttons for 10s (the unit must be in Run mode). Indication goes out briefly (acknowledgement of locking / unlocking). Units are delivered from the factory in the unlocked state. If the unit is locked, it is possible to indicate

• the current switch point 1 (press the Mode/Enter button once),

• the current switch point 2 (press the Mode/Enter button two times),

• the setting of the function “monitoring excess flow” (press the Mode/Enter button three times). 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 according to the programming: ON with the NO function and OFF with the NC function. Failure indication: 5 left LED’s flashing in case of short-circuit at the output S1; 5 right LED’s flashing in case of short-circuit at the 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.

to EN50178, SELV, PELV; referring to UL: see page 24 (Electrical connection).■■ Setting of the detection range The detection range (window) is determined by:

• Adjustment to the required maximum flow (HI-Teach) = upper limit of the window. This setting is sufficient for the majority of waterbased appli- cations.

• Adjustment to the required minimum flow / flow standstill (LO-Teach) = lower limit of the window.

• Adjustment to maximum flow (HI-Teach) The unit detects the current flow and sets this value as the maximum value for the LED display (LED 9).

Press the Learn/Set button and keep it pressed. The green LEDs on the right and on the left flash, after 5s the LED bar (green) fills from left to right (release the button as soon as the first LEDs light). The indication goes off briefly. The unit stores the current flow as maximum flow and passes into the operating mode. LO HI LO HI HILO >5...<10s

S• Adjustment to minimum flow / flow standstill (LO-Teach), optional The unit detects the current flow and sets this value as the minimum display value for the LED display. In normal operation the first green LED (LED 0) flashes when the flow falls below this value (or when it comes to a standstill). NOTE: The LO-Teach operation may only be carried out after the HI- Teach operation. ENGLISH

Press the Learn/Set button and keep it pressed. The green LEDs on the right and on the left flash, after 5s the LED bar (green) fills from left to right after a further 5s the LED bar (gren) fills from right to left (release the button as soon as the first LEDs on the right light). The indication goes off briefly. The unit stores the current flow as minimum flow and passes into the operating mode. LO HI HILO LO HI >10...<15s

Allow the medium to flow through the system at the required minimum flow rate or bring to a standstill.

*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. - SP1: min. setting value = LED 0; max. setting value = LED “SP2”. - SP2: min. setting value = LED “SP1”; max. setting value = LED 9. **Overflow: If the flashing LED and the lit LED exceed the maximum setting value, the cycle starts again at the minimum setting value.

Press the Mode/Enter button. The current switch point is indicated: LED lit: coarse setting, LED flashes: fine setting. Press the Learn/Set button and keep it pressed After 5s the switch point is increased* (incremental by pressing briefly or scrolling by holding pressed). Indication: The flashing LED moves from left to right. After LED 9 has been reached the cycle starts again at LED 0. The LED which is constantly lit moves on by one position.** LO HI LO HI LO HI 1 time (= setting of SP1) 2 times (= setting of SP2)

>5s■■ Monitoring excess flow With this function the position of the display window within the detection range can be defined: Shift the LED for the maximum dis- play value to position 8, 7, 6 or 5. In the case of maximum flow all LEDs from 0 up to this LED are lit. The LEDs above the range signal excess flow. If the switch point is above this range, the unit switches in the case of excess flow. Please note: The display value is reset (to LED 9) after each maximum flow rate adjustment (HI-Teach. ENGLISH

SHysteresis function When the flow rises, the outputs switch when the corresponding switch point (SPx) has been reached. When the flow falls again, the output switches back when the value "SPx minus hysteresis" has been reached.. The hysteresis is considerably influenced by the choice of the operat- ing range on the sensitivity curve of the sensor:

• In the case of adjustment to HI-Flow values in the range 0 ... 60cm/s the hysteresis is 2 - 4cm/s (values apply to water).

• In the case of adjustment to HI-Flow values above 100cm/s the hysteresis increases as the flow rises. The typical response time of the unit is 3 ... 8s. It can be influenced by setting the LO-Teach and the switch point:

• The lower the LO-Teach or the switch point is set, the faster the unit switches on.

• The higher the LO-Teach or switch point is set, the faster the unit switches off. ENGLISH
