Function and features

The flow monitor

• detects the flow velocity in liquid and gaseous media
- switches the outputs according to the programming (N.O./or-N.C./, programmable by wiring; →page 24)
- and indicates the relative flow value within the adjustable detection range by means of LEDs:

• LED 0 = lower limit of the detection range (maximum value / LO)
• LED 9 = upper limit of the detection range (minimum value / HI)

- It is also possible to indicate:

• Switching status (LED red: flow below the switch point, LED orange: flow has reached the switch point).
• Excess flow: LED 9 flashes if the flow is considerably higher (2 LEDs) than the display range.
• Underflow / flow standstill: LED 0 flashes if the flow is lower than the display range.

Installation

The unit is adaptable for various process fittings (adapters to be ordered separately as accessories).

• In the case of horizontal pipes mount the unit from the side, if possible (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).

Programming diagrams / Technical information

■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 applications.
• 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).

1	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.
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(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.
	>5...<10s

- 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.

1	Allow the medium to flow through the system at the required minimum flow rate or bring to a standstill.
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
	>10...<15s
			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.

■ Setting of the switch points

Switch point 1 (SP1) = lower value, setting range: LED 0 ... SP2

Switch point 2 (SP2) = upper value, setting range: SP1 ... LED 9

1	1 time (= setting of SP1)2 times (= setting of SP2)	Press the Mode/Enter button.The current switch point is indicated:LED lit: coarse setting, LED flashes: fine setting.
2	>5s	Press the Learn/Set button and keep it pressedAfter 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.**
3		Press the Mode/Enter button briefly (acknowledgement).The set switch point becomes effective; the unit passes into the operating mode.

*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.

■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 display 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.

1		Press the Mode/Enter button three times. The current setting is indicated (green LED).
2		Press the Learn/Set button for 5s (until LED flashes).
3		Press the Learn/Set button several times until the requested LED flashes (LED 8, 7, 6 or 5). Each time the button is pressed the LED moves back by one position. When it is lower than LED 5 the cycle starts again at LED 9.
4		Press the Mode/Enter button briefly (acknowledgement). The indication goes off briefly. The unit stores the new setting and passes into the run mode.

Please note:
The display value is reset (to LED 9) after each maximum flow rate adjustment (HI-Teach.

■Return to factory setting

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 (green) fills from right to left,

after a further 5s the LED bar (orange) fills from left to right (release the button as soon as the first orange LEDs light).

The indication goes off briefly. All settings are returned to factory setting and the unit passes into the run mode flow.

Hysteresis 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 operating 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.
