to EN50178, SELV, PELV■■ 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.

• Additionaly: adjustment to the required minimum flow / flow standstill (LO-Teach) = lower limit of the window (optional).

• 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

Apply the operating voltage. After approx. 15s the unit is ready. Allow the medium to flow through the system at the required maximum flow rate.

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.

• Remote adjustment You can also adjust the unit via the programming wire, if the function for remote adjustment is active. Apply the operating voltage (+U

) to pin 2 (P) for the respective time: >5...<10s for HI-Teach; >10...<15s for LO-Teach ENGLISH

If the operating voltage is applied to pin 2 for more than 15s,

• all adjustments are set back to factory setting. If the operating voltage is applied to pin 2 for more than 20s,

• the adjustment does not become effective; the unit passes into the operating mode with unchanged values,

• the unit is locked (the buttons are inactive as long as the operating voltage is applied to pin 2).

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.

S■■ Setting of the switch point The switch point is preset at the factory (LED 7). The setting influ- ences the reaction time of the unit.

• High switch point = fast reaction in the case of flow decrease.

• Low switch point = fast reaction in the case of flow increase.

*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. **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 briefly. 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 x

Press the Mode/Enter button briefly (acknowledgement). The indication goes off briefly. The set switch point becomes effective; the unit passes into the operating mode. HILO

>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

Press the Mode/Enter button briefly (acknowledgement). The indication goes off briefly. The unit stores the new setting and passes into the run mode.

5s■■ Activate / deactivate the function for remote adjustment If the function is active, the unit can be adjusted by applying voltage to pin 2. Unit supplied: function active. If the function for remote adjustment is active and the operating voltage is applied to pin 2 for more than 20s, the unit is locked (the but- tons are inactive as long as the operating voltage is applied to pin 2). Use 4-wire connection cables without a link between pins 2 and 4. With 3-wire sockets with a link between pin 2 and pin 4 switching of the output stage triggers the remote adjustment!

SHysteresis function When the flow rises, the output switches when the switch point (SP) has been reached. When the flow falls again, the output switches back when the value "SP 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.
