LPH (litre/hour) value for nominal diameter 19 and 24 = displayed value × 10• The flow monitor detects the flow rate of water,

• shows the current flow rate on its display, (max. value displayed: final value of measuring range + 20%)

• and generates 2 output signals according to the set output configuration. Application: water. (please see the maintenance details on page 29)

• For seamless precision steel to DIN 2391/1 and T-pieces to DIN 2353.

• Adjustable to T-pieces with nominal diameter of 15mm, 19mm or 24mm. Measuring range

gallons / hour cubic metre / hour for nominal diameterDisplay range Run mode (Normal operating mode) With power on and the power-on delay time elapsed* (approx. 10s) the unit is in the Run mode. It monitors and generates output signals according to the set parameters. The display indicates the current flow (can be deactivated, → page 32). The red LEDs indicate the switching state of the outputs. *During the power-on delay time the most important parameter values are displayed briefly, then the current measured value is indica- ted. Even if the display is deactivated (diS = OFF), the most important parameter values are indicated, then the current measured value is indicated for 15s, then the display goes out. Both outputs are switched according to the programming: ON with the NO function (Hno/Fno) and OFF with the NC function (Hnc/Fnc). Note: When the hysteresis function is active, the outputs remain in this switching state after the power-on delay time has elapsed if the flow is between SPx and rPx. If output 2 is configured as analog output, the output signal is 20mA or 10V.

For nominal diameter 19 and 24, 1/10 of the LPH value is displayed. The displayed value must be multiplied by factor 10. Example: displayed value = 98; real value = 98 * 10 = 980 LPH. Operating modesDisplay mode (Indication of parameters and the set parameter values) When the "Mode/Enter" button is pressed briefly, the unit passes to the Display mode which allows parameter values to be read. The inter- nal sensing, processing and output functions of the unit continue as if in Run mode.

• The parameter names are scrolled with each pressing of the "Mode/Enter" button.

• When the "Set" button is pressed briefly, the corresponding para- meter value is displayed for 15s. After another 15s the unit returns to the Run mode. Programming mode (Setting of the parameter values) While viewing a parameter value pressing the "Set" button for more than 5s causes the unit to enter the programming mode. You can alter the parameter value by pressing the "Set" button and confirm the new value by pressing the "Mode/Enter" button. The internal sensing, processing and output functions of the unit continue as if in Run mode with the original parameter values unless a new value is confirmed. The unit returns to the Run mode when no button has been pressed for 15s. Step 1 Grease the nut (A) with greasing paste to ensure the nut can be loosened and tightened several times. Note: No grease must be applied to the sensor tip. Remove the protective cap (B) from the sensor tip. Insert the unit into the T-piece.

ENGLISH Installation

greaseStep 2 Align the unit as shown such that the flats are parallel with the pipe. The arrow mark should be upstream, if possible. Fasten the nut, max. tightening torque 70Nm, while maintaining this orientation. Finally, rotate the top part of the sensor for best visibility of LED display. Minimum distance To avoid malfunction a minimum distance between the flow moni- tor and bends, valves, changes in cross-section or such like must be observed:

• Min. 10 x pipe diameter upstream (A).

• Min. 5 x pipe diameter down- stream (B). (This information refers to lami- nar flow).

flatsThe unit must only be connected by an electrician. The national and international regulations for the installation of electrical equipment must be observed. Voltage supply to EN50178, SELV, PELV. Disconnect power before connecting the unit. Wiring:

2: OUT2 4: OUT1 1 x n-switching / 1 x analogThe unit can be electronically locked to prevent unwanted adjustment of the set parameters: Press (in Run mode) both programming buttons for 10s. As soon as the indication goes out the unit is locked or unlocked. Units are delivered from the factory in the unlocked state. With the unit in the locked state is indicated briefly when you try to change parameter values.

Mode/Enter Set Mode/Enter Set Mode/Enter Set Press the Mode/Enter button several times until the respective parameter is displayed. Press the Set button and keep it pressed. The current parameter value flashes for 5s, then the value is increased* (incremental by pressing briefly or scrolling by holding pressed). Press the Mode/Enter button briefly (= acknowledgement). The parameter is displayed again, the set parameter value becomes effective.

Change more parameters: Start again with step 1. Finish programming: Wait for 15s or press the Mode/Enter button until the current measured value is indicated again. *Decrease the value: Let the display of the parameter value move to the maximum setting value. Then the cycle starts again at the minimum setting value. Select the display unit (Uni) before setting the switch points (SPx, rPx) or the limits for the analog output signal (ASP, AEP). This avoids rounding errors generated internally during the conversion of the units and enables exact set- ting of the values. If no button is pressed for 15s during the setting procedure, the unit returns to the Run mode with unchanged values.After mounting, wiring and setting check whether the unit operates correctly. Failure indication 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 Operation / maintenance excess flow (flow > 120% of the final value of the measuring range) flashing: short circuit of the switching output 1 flashing: supply voltage too low (< 19V); the switching outputs are reset, the analog signal is reset to 0V / 0mA. flashing: short circuit of the switching output 2 flashing: short circuit of both switching outputsAdjustable parameters

Technical information / Functioning / Parameters Switch-on point 1 / 2 Upper limit value at which the output changes its switching status. SP2 is active only if OU2 = Hno, Hnc, Fno or Fnc. Switch-off point 1 / 2 Lower limit value at which the output changes its switching status. rPx is always lower than SPx. The unit only accepts values which are lower than SPx. Changing the switch-on point also changes the switch-off point (the distance between SPx and rPx remains constant). If the distance is higher than the new switch point, it is automati- cally reduced: rPx is set to the minimum setting value (0.0). rP2 is active only if OU2 = Hno, Hnc, Fno or Fnc Setting range for SPx / rPx: → page 59. Configuration of output 1 4 switching functions can be set: - Hno = hysteresis / normally open - Hnc = hysteresis / normally closed - Fno = window function / normally open

Enhanced functions This menu item contains a submenu with additional parameters. You can access these parameters by pressing the SET button briefly. Min-Max memory for flow rate:

• HI: displays the highest measured flow range

• Lo: displays the lowest measured flow range Erase the memory: - Press the "Mode/Enter" button until HI or Lo is displayed. - Press the "Set" button and keep it pressed until “- - -” is displayed. - Then press the "Mode/Enter" button briefly. It is recommended to erase the memory as soon as the unit starts working under normal operating conditions. Customer-specific calibration (explanation → page 35) If the function is active, the current flow value is displayed. - Press the SET button to set the requested value (scrolling by holding pressed; incremental by pressing briefly). - Acknowledge with the Mode/Enter button. After calibration the calibration indicator is displayed at the upper left corner. Calibration is only possible for values > 25% of the final value of the measuring range. For smaller values Lo is displayed, the set- ting of the parameter is disabled. Setting range: -40% ...+40% of the final value of the measuring range; max. value displayed: final value of the measuring range + 20%. Calibration reset - Press the "Mode/Enter" button until CAr is displayed. - Press the "Set" button and keep it pressed until “- - -” is displayed. - Then press the "Mode/Enter" button briefly. The calibration set by CGA is reset; the calibration indicator no longer lights.32 Start-up delay During this time special conditions apply to the switching of the outputs (explanation → page 36).

• Adjustable in steps of 1s.

• Setting range: 0 ... 50s (0 = start-up delay not active). The time applies to both outputs. Output palarity 2 options can be selected: PnP = positive switching, nPn = negative switching. This setting applies to both switching outputs. Setting of the display 3 options can be selected:

• OFF = The display is deactivated in the Run mode. When one of the buttons is pressed the current measured value is displayed for 15s. When the Mode/Enter button is then pressed, the display mode is opened. The LEDs indicating the switching state and the calibration indicator remain active even if the display is deactivated. Display unit 5 options can be selected:

• CPH = cubic metre /hour For nominal diameter 19 and 24, 1/10 of the LPH value is dis- played. The displayed value must be multiplied by factor 10. Example: Displayed value = 98; real value = 98 * 10 = 980 LPH. Labels for the different units of display are enclosed with the unit. Stick the respective label on the sensor or fill in the blank label. Select the display unit before setting the switch points (SPx, rPx) or the limits for the analog output signal (ASP, AEP). This avoids rounding errors generated internally during the conversion of the units and enables exact setting of the values.Measurement accuracy Typical measurement errors for water and different temperatures of the medium. Dirt / build-up on the sensor tip affects the measurement accura- cy. Check the sensor tip for build-up from time to time. If necessary, clean it with a soft cloth and a vinegar cleansing agent. Hysteresis The hysteresis keeps the switch- ing state of the output stable if the flow varies about the preset value. When the flow is rising, the out- put switches when the switch-on point has been reached (SPx). When the flow is falling again, the output switches back when the switch-off point (rPx) has been reached. The hysteresis can be adjusted: First the switch-on point is set, then the switch-off point with the requested difference.

Hno hysteresis HncWindow function The window function enables the monitoring of a defined acceptable range. When the flow varies between the switch-on point (SPx) and the switch-off point (rPx), the output is switched (window function/NO) or not switched (window func- tion/ NC). Scaling the measuring range (analog output) With the parameter "Lower end of analog output" (ASP) you can select the measuring value for which the output signal is 4mA or 0V. With the parameter "Upper end of analog output" (AEP) you can select the measuring value for which the output signal is 20mA or 10V. Minimum distance between ASP and AEP = 40% of the final value of the measuring range. Voltage output 0 ... 10V

AEP ASP0 MEW factory setting measuring range scaled MEW = value of measuring range The output signal is between 0 and 10V in the set measuring range. It is also indicated: Flow above the measuring range: output signal > 10V.Current output 4 ... 20mA Customer-specific calibration (CGA) This calibration changes the slope of the curve of measured values. It influences the display and the analog output. Calibration is only possible for values > 25% of the final value of the measuring range. It can be reset (→ menu item CAr).

AEP ASP0 MEW factory setting measuring range scaled MEW = value of measuring range The output signal is between 4 and 20mA in the set measuring range. It is also indicated: Flow above the measuring range: output signal > 20mA.

A = curve of measured values without calibration A1, A2 = curve of measured values after calibration displayStart-up delay (dSt) If the start-up delay is active (dSt > 0), the following conditions apply: As soon as the flow has reached the value 3% of the final value (FV)

• the start-up delay starts and

• the outputs are switched according to the programming: ON with the NO function (Hno / Fno), OFF with the NC function (Hnc/Fnc). During the start-up delay 2 cases are possible:

• fast increase of flow, switch point / acceptable range are reached within dSt → outputs remain active

• slow increase of flow, switch point / acceptable range are not reached within dSt → outputs are reset Example dSt with hysteresis function

flow reaches 3 % of the final value (FV) → dSt starts, the output becomes active dSt has elapsed, flow has reached SP → the output remains active flow falls below SP but remains above rP → the output remains active flow falls below rP → the output is reset flow reaches 3 % of the final value again → dSt starts, the output becomes active flow reaches SP → the output becomes active dSt has elapsed, flow has not reached SP → the output is reset Hno Hnc

ENGLISH flow reaches 3 % of the final value (FV) → dSt starts, the output becomes active dSt has elapsed, flow has reached the acceptable range → the output remains active flow exceeds SP (leaves the acceptable range) → the output is reset flow falls below SP again → the output becomes active again flow falls below rP (leaves the acceptable range) → the output is reset again flow reaches 3 % of the final value again → dSt starts, the output becomes active flow reaches acceptable range → the output becomes active dSt has elapsed, flow has not reached the acceptable range → the output is reset

1/10 of the LPH value is displayed (the displayed value must be multiplied by factor 10).
