To set the value of the alarm, you change the figure by figure with “+/-“ if necessary and confirm with “M”. Next figure will be highlighted and you repeat until you get your desired value. Note It is not possible to set the alarm outside the flow range (Q min/Q max) Also the hysteresis effects on the alarm settings. L1 cannot be set higher than Q max - “Hyst1”, and L2 can’t be set lower than Q min - “Hyst2”. Hysteresis The hysteresis is necessary to avoid the alarm to ripple (go on and off) when the flow is close to the set point. The hysteresis is changeable separate for each alarm between 2.5, 5 and 10% (of Q max). To change the hysteresis, you scroll to that value you want to change and then press the ”M” button so the value highlights and then use “+/-“ to change and confirm with the ”M” button. To leave this menu, scroll down to “Return” and press “M”, or press “C” button during 2 sec. “Return” takes you back one step in the menu, the “C” button takes you back directly to the operating mode.

Totalizer To activate the totalizer; when “Show ?Q” is highlighted press “M” to move to the right. Use ”+ or -” to set ”On” and confirm with ”M”. The totalizer will start in the same time you confirm “On”. Press “C” 2 sec. to go back to operating view. The value of the totalizer is the same as the displayed unit, so if you have l/min, l/s or l/h, the unit is liters, and if you have m³/min, m³/h the totalized value will be in m³. If you have the displayed unit in “%”, the totalizer will not work The totalizer works as long the flow is within the flow range. If the flow should go outside the range or there is a power failure, the totalizer goes back to “Off” and also disappear from the display. If you want to go back to totalizing mode, you need to reactivate it. It is also possible to restart the counter by press “-“ in the “Operating mode”. Note The end value for the totalizer is 99999, when this value reaches the counter stops. Display Depending on the mounting orientation of the Flow meter, the display can be rotated in 4 different angles, 0°, 90°, 180°and 270°. To change the orientation, scroll down to “Display” and press “M” and when “Rotate” is highlighted press “M” to move to the right. Use “+” or “-“ to rotate to the angle you want, and confirm with “M”.

To leave this menu, scroll down to “Return” and press “M”, or press “C” button during 2 sec. “Return” takes you back one step in the menu, the “C” button takes you back directly to the operating mode. Filter This filter will slow down the response time for the output signal and the displayed flow value. It can be necessary to use this function if you are facing problems in your pipe system with pressure chocks or variations in the flow, giving the display and the output signal an instable value. The filter can be set between 1 and 99, where level 2 is factory default setting. The micro processor makes 5 measures per seconds and creates an average value of this, then, for level 2, adds this value to the latest value and divides with 2. On level 3, it takes the new average value and add with the two latest and divides this with 3, etc. Note Don’t set the filter higher than necessary as this will have an effect on detecting “true” changes in the flow. The responds time will approximately be 0.2 sec x filter value. To change the filter value, scroll down in the “Options” menu until “Filter” will be highlighted. Then press “M” and the input box will lights up. To set the value you can change figure by figure with “+/-“ if necessary and you confirm with “M”. Next figure will be highlighted and you repeat until you get the desired value and then confirm with the “M” button To leave this menu, scroll down to “Return” and press “M”, or press “C” button during 2 sec. “Return” takes you back one step in the menu, the “C” button takes you back directly to the operating mode. Simulation This function gives you the possibility to create and simulate a real mA-signal from the unit even if you don’t have any flow. For example you want to check other instruments or functions in your system. In this case you can simulate a desired flow or mA-signal from the unit. Note It’s only possible the simulate the mA-signal, not the frequency output Warning Before using this function, be sure that the unit measuring actual flow, as this simulation will disconnect the real signal and then disturb receiving instruments. To activate the simulation, scroll down in the “Main menu” until “Simulation” will be highlighted and press the “M” button. Scroll down to “Q sim” or “mA sim” and press the “M” button, and the input box will lights up. To set your desired value you change figure by figure with “+/-“ and confirm with the “M” button. The next figure will be highlighted and you repeat until you get the right value. Confirm with the “M” button. Scroll down to “Start” and press the “M” button to start the simulation Configuration guide for D-series display 8 70A5E11, 2010-04-20/ÅE The display will flash between black/white during the simulation. To cancel, press the “C” button. Info This menu will give you information about the version of soft ware and hardware and also the type of output signal i.e. zero-based or Non-zero based. Factory default Warning Warning All changes in this menu will have an effect on the function of the flow meter. This menu is only necessary when you change to a new orifice (another flow range), or want to change the output signal from Zero-based to Non-Zero-based or opposite or make a recalibration of meter. All other configurations will be made in the “Main menu” From the operating mode you reach the “Factory default” menu by press the buttons -, +, and C consecutively and keep them pressed 2 sec until the menu lights up T/D: show you the actual flow turn down, in this case 1:5 (Q min is five times less than Q max). This is factory preset and cannot be changed from here. Changing of flow range for a new orifice Scroll down to “Q unit” and press the “M” button to move to the right. Set the right unit for the new orifice by using “-/+”, and confirm with the “M” button. l/s, l/min, l/h, m³/min, m³/h, USGpm, CFM, or CFH Scroll down to “Q max” and press the “M” button and the input box will light up. Set the right value according to the new orifice To set the value you change figure by figure with “+/-“ if necessary and confirm with the “M” button. Then next figure will be highlighted and you repeat until you get the right value. Configuration guide for D-series display 9 70A5E11, 2010-04-20/ÅE Output signal The output signal can be set in two different ways; “Zero” (zero-based) means that 4-20 mA represent 0-100% of Q max. This is most common and the factory default. “Non-Zero” (non-zero-based) means that 4-20 mA represent the flow range (4 mA = min value of the flow range), see the graph on next page To change, scroll down to “mA signal” and press the “M” button to move to the right, and then change by using “-/+” and confirm with the “M” button To leave this menu, scroll down to “Return” and press “M”, or press “C” button during 2 sec. “Return” takes you back one step in the menu, the “C” button takes you back directly to the operating mode. On Zero-based units, the signal goes from 20 mA down to the min value (20% or 50% depends of the turn down), 2% below min the signal drop down to 4 mA. On Non zero-based the signal goes from 20 mA down to 4 mA at the min value (20% or 50% depends of turn down), 2% below min the signal stop at 3,7 mA. The signal have an end value at max, 20,3 mA. Configuration guide for D-series display 10 70A5E11, 2010-04-20/ÅE Calibrate The meter is already calibrated from factory and shall normally not be necessary to recalibrate. If you still want to do this, you need a master meter so you can adjust to a correct flow. A new flow calibration will overwrite the old factory calibration and it’s not possible to recall it. Flow Scroll down to “calibrate” and press the “M” button and when “Flow” is highlighted press the “M” button once more. Chose “Type”; Zero or Non-zero, by pressing the “M” button and use “-/+” to change and confirm with the “M” button. scroll to “No of points” and choose how many calibration points you want to set. From factory, Turn down 1:5 is calibrated at 9 points and Turn down 1:2 at 5 points (D2 and D5 respectively). Change the number of points by pressing the “M” button and the input box will lights up. Set the value with “+/-“ and confirm with the “M” button. Scroll down to “Start” with “-“ and press the “M” button If you have come this far by mistake, you can interrupt the calibration without causing any changes here or you can go on with the calibration by adjusting a stable flow through your reference meter matching the value on the display “Set flow to”. Move with “+” so “Next” will be highlighted and press the “M” button to confirm The adjusting of the calibration takes some seconds and during this time you need to keep the flow stable. Next step in the calibration lights up and you can adjust to the flow the software ask for and press the “M” button to confirm. The calibration always start on Q max and finish on Q min and split automatically the calibration points proportional over the flow range. Repeat this procedure through the whole calibration. Configuration guide for D-series display 11 70A5E11, 2010-04-20/ÅE After the last calibration point you get a confirmation whether the calibration was “OK” or “Failed”. If the calibration was OK, the new calibration will be saved as default in the E²-memory and the display goes back to the factory default menu. To leave the menu, scroll down to “Return” and press the “M” button, or press the “C” button during 2 sec If the calibration Failed, the display goes back to the “Calibrate menu”, and you have to do a new calibration by start from the beginning of the calibration procedure. The old calibration is still saved in the E²-memory as long a new calibration not passed OK. mA signal The output mA-signal from the meter is also possible to calibrate. It is already done before leaving the factory, but if you, for some reason to suspect that it is not correct, there is a possibility to adjust the mA-signal as follows;. Disconnect the cables from the mA-output (3 and 4 on the terminal block) Connect a calibrated mA-meter (multimeter) to terminal 3 and 4. Scroll down to “Calibrate” and press the “M” button. Scroll to “mA signal” and press the “M” button. 4 mA will be displayed and now you shall compare this value with your multimeter and if necessary you can adjust the signal from the flow meter 10 step up and down with the “-/+” buttons. Each step is 0.05 mA. Adjust as close as possible and confirm with the “M” button. The program will jump automatically to 20 mA. Repeat the adjusting sequence as above and press the “M” button to confirm. Reconnect the cables on terminal 3 ad 4. To leave this menu, scroll down to “Return” and press “M”, or press “C” button during 2 sec. “Return” takes you back one step in the menu, the “C” button takes you back directly to the operating mode.
