13 Adjustment 4 Adjustment 4.1 Indicating and adjustment elements A rotary switch is located on the circuit board. It is used for adjustment of the instrument address on DISBUS. This setting is necessary if the measured values are be transmitted via the DISBUS cable external instruments, e.g. VEGADIS 174 indicating instrument, VEGACOM 557 interface converter or other VEGAMETs. With these external instruments, the allocation of a received measured value a specific measurement loop can be determined by means of the address. The adjustment range 1 F corresponds the DISBUS addresses Facry setting: 1 Note: With address 0, the VEGAMET does not participate in the DISBUS communication. Rotary switch F A B E C D The set instrument address on the DISBUS can be indicated on the LC display. Note If several VEGAMET are linked via the DISBUS, each address must only be assigned once!

16 Adjustment 4.4 Configuration and parameter adjustment No matter whether you set up your VEGAMET via the keys of the adjustment module or via a PC with the software VVO, the procedure is always the same. Proceed in the following sequence: - configuration (if not already configured as facry setting) - parameter adjustment. In this operating instructions manual, the adjustment steps are described which are directly carried out on the keys of VEGAMET. The adjustment via the software VVO is described in a separate manual. Configuration Configuring means assigning or setting (once) functions. VEGAMET requires a (mostly once) basic co-ordination that determines the applications and the assignments of the inputs and outputs. Choices can be made from existing functions and options. This procedure is called configuration. The signal conditioning instruments are delivered with a configuration which only needs be changed in special cases. The basic configuration includes the following steps: 1 Configuration measurement loop Choose the kind of application (level, gauge ) Choose sensor type (capacitive, hydrostatic ) Determine application (standard, level difference ) Determine options (no option, corrections ) 2 Configuration of inputs Specify from where your VEGAMET receives the input data (sensor, other VEGAMET) Enter sensor characteristics values (meas. range, current range) 3 Configuration of outputs All outputs (except fail safe relay) can been assigned one sensor or can be switched off. After basic configuration, VEGAMET goes in operating mode and indicates the actual measured value. The other configurations should be carried out after the parameter adjustment. Parameter adjustment Parameter adjustment means changing the values. Signal conditioning instruments have many parameters, the values of which can be modified, such as for example the integration time of s. The modification of these values is called parameter adjustment. The parameter adjustment does not influence the configuration. Take notice that parameter adjustment is only possible after a configuration has been carried out (e.g. set values of the current input after the current output has been assigned). Note: The measurement loop configuration can only be modified if a " single measurement or " linked application has been carried out before (under "Additional functions ). 16 VEGAMET 515

17 Setup 5 Setup Adjust the VEGAMET instrument address with the rotary switch on the circuit board (if measured values should be transferred via the DISBUS cable external instruments, e.g. VEGADIS 174 indicating instrument, VEGACOM 557 interface converter or VEGAMET). Install VEGAMET. Connect sensor and power supply. After switching on, the display indicates for approx. 10 secs the instrument type and the software version, e.g. "MET 515 V1.12. If no measurement loop has yet been configured, the display shows "Configuration, the red fault indicar LED also lights. In this case, proceed as described under "6.1 Configuration measurement loop. If a measurement loop has already been configured, the display shows a value, e.g. " 21.8.You can now carry out the settings. VEGAMET

Difference VEGADIF VEGABAR Moniring The measurement loop configuration is usually provided as a facry setting. Should a general modification of the measurement loop configuration be necessary, first of all a " single measurement or " linked application should be carried out (with " single measurement the VEGAMET is prepared for configuration of two independent single measurements. With " linked application it is prepared for configuration of linked applications). Only then can adjustments in the menu items Application, Sensor type, Mode and Option be modified. Proceed in the menu items in the given sequence. The adjustment or selection possibilities always depend on what was adjusted in the previous menu item. When e.g. in the menu item Application "Level is adjusted, only one sensor type can be selected in the menu item "Sensor type which is suitable for level detection. As soon as you have made an adjustment in the menu item "Option and confirmed it, the display shows the message: "TAG being created!. You choose the application 4/20 ma if you want connect a sensor of another manufacturer VEGAMET. In the following illustrations, different types of applications are shown. In addition, you will see which adjustments you have carry out in the menu items "Sensor type and "Mode. The menu item "Position D only appears when in the menu item "Option either "Offset correction or "Real value correction has been set.

The enquired VEGAMET number corresponds the DISBUS address of the instrument (see chapter 4.1). Enter under "Sensor characteristics the values stated in the test certificate (of hydrostatic pressure transmitters). These settings are important if you carry out a differential measurement with your VEGAMET. The menu items "Min. meas. range and "Max. meas. range are only visible with hydrostatic pressure transmitters.

The gauge difference is measured on each weir with one VEGAMET 515. Normally two sensors would be required for each VEGAMET. However, since the gauge value of the upstream water is valid for both VEGAMETs, one sensor is sufficient for the upstream water. The input signal of sensor 1 (upstream water) is transmitted via the DISBUS cable from one VEGAMET (MET04) the other VEGAMET. The value of sensor 1 is therefore available both signal conditioning instruments. 30 VEGAMET 515

33 Parameter adjustment 7 Parameter adjustment 7.1 Adjustment with medium You can either carry out the adjustment with medium or without medium. To carry out an adjustment with medium, it is necessary that you know the percentage values of the vessel for the actual filling. Adjustment example Maxadjust at 100,0 You know that your vessel is presently filled up 80. Move the menu item "Max-adjust at Briefly push the [ ] key, so that the figure flashes (editing mode). Maxadjust at 80,0 Continue pushing [ ] until the figure 80.0 appears on the display. Now push [OK] save the adjustment. Signal conditioning Minadjust at 0,0 mode). Then if your filling is for example 10, move the menu item "Minadjust at 0.0. Briefly push the [+] key until the figure 0,0 flashes (editing with medium Adjustment Minadjust at 0,0 Scaling Maxadjust at 100,0 Lin. curve linear Integr ation time s 0 Density in kg/dm DK value (Er) For this procedure, percentage values must be entered for min. and max. that correspond the actual fillings. The sequence of the min. or max. value is not important. For example, if you know that your filling is presently 80, you can enter in the menu item Max. adjustment the value "80. Then if your filling is, for example, 10, you enter in the menu item Min. adjustment the value "10. The larger the difference between the two adjustment points, the more exact the measurement over the whole measuring curve. It follows that adjustment at 0 and 100 would be best. For practical reasons, however, it is not always possible completely fill or empty a vessel. The distance between the two adjustment points, however, should be at least 10 of the sensor range. Minadjust at 10,0 Continue pushing [+] until "10 appears on the display. Now push [OK] save the adjustment. Of course, you can carry out the adjustment with medium also at 0 and 100 filling. Please note: The figures 0 and 100 must flash (editing mode) before they can be saved with the [OK] key. Note: If the medium is later changed (medium with another density value or dielectric constant) and no new adjustment is possible or if the MET indication and the DIS outputs refer height in metres, note the following: For applications with hydrostatic pressure transmitters, the adjusted density value must correspond the value of the medium. For applications with capacitive electrodes, the adjusted dielectric constant must correspond the value of the medium (water has a density of 1.0 kg/dm 3 and a dielectric constant of 81.00). The menu items "Density or "DK value are displayed if the respective sensor type was selected under "Configuration measurement loop. VEGAMET

34 Parameter adjustment 7.2 Adjustment without medium Adjustment example Adjustment Meas. value indication You know the data of your sensor, i.e. you know the sensor delivers at 0 filling a current of 4.2 ma and at 100 filling a current of 15.5 ma. Enter these values in the menu items ma at 100 with medium w.o. medium Adjustment ma bar m Offset correction Sensor unpres sur d? 0 at ma 4, at ma 20, ma at 0 Offset corr. Now! 0 at ma 4, at ma 15,500 For the "Adjustment without medium, two anticipated levels, gauges etc., corresponding 0 and 100 must be entered. Depending on the sensor type used, the adjustment can be carried out in ma, bar or m. In these two menu items, you enter the sensor values. Use the [+] and [ ] keys set the values and [OK] save the values. The menu item "Offset correction is activated when connecting hydrostatic pressure transmitters. The offset correction should be carried out after installation of the sensors because the sensor values can differ slightly in various installation positions (vertical or horizontal mounting). With the offset correction, the measured data of an unpressurized sensor (vessel empty) are detected as a corrective value and taken in account in all all subsequent measurements. 34 VEGAMET 515

35 Parameter adjustment 7.3 Adjustment with linked measurements Linked measurements are possible with VEGAMET 515. For this reason, two sensors are connected which carry out one measurement each (TAG1 and TAG2). VEGAMET 515 calculates from the two sensor values a third value, e.g. a gauge difference (TAG3). When adjusting linked measurements, facrs other than those with single measurement will possibly have be taken in account. For all linked measurements, it is important enter the sensor characteristics values before the adjustment. To do this, move the menu item under "Sensor characteristics.

36 Parameter adjustment Adjustment of gauge difference Upstream water Gauge difference TAG1 TAG2 TAG3 Downstream water The adjustment of the individual measurement loops TAG1 and TAG3 is the same as the adjustment of single measurement loops, see "7.1 Adjustment with medium and "7.2 Adjustment without medium. It is also possible carry out the adjustment only for measurement loop TAG3. If you want adjust all three measurement loops, the sequence is not important. Make sure the gauge is the same (difference = 0 ). Enter in the menu item "Min-adjust at the figure "0.0 (push the "+ or "- key until the figure "0.0 flashes, then push the "OK key). Mark the position of the sensor in the downstream water. Suspend the sensor 30 cm higher (if 30 cm should correspond 100 ). A 30 cm lower gauge is now simulated. Enter in the menu item "Max-adjust at the figure "100.0 (push the "+ or "- key until the figure "100.0 flashes, then push the "OK key). Suspend the sensor in the original position. Note: You can also suspend the sensor in upstream water in a lower position carry out the max. adjustment. Adjustment of the gauge difference measurement loop (TAG3) Suspend the sensors the same level. Note that a difference of 30 cm (e.g. with weir control) can correspond 100. Adjustment without medium The easiest way would be carry out the adjustment without medium in the adjustment unit "m.

37 Parameter adjustment Adjust in the menu item "Adjustment the unit "m. Enter in the menu item "0 at m and "100 at m the values 0.00 and 0.30 (if 30 cm should correspond 100 ). Only carry out the offset correction at this point when both sensors are unpressurised. If you want carry out the adjustment in ma or bar, you have enter the difference values of the sensor currents or the pressures. If you want that the gauge difference of 30 cm is shown in the meas. value indication in cm, you can carry out a scaling (see "7.4 Scaling ). No. 3 Adjustment with level measurement in pressurized vessels For the adjustment of measurement loop TAG1 (level) you can proceed in the same manner as for the adjustment of a single measurement loop. The adjustment can be either carried out with or without medium (product). Measurement loop TAG2 (gauge pressure) is adjusted without medium, preferably in "bar. For level measurement (TAG1), an adjustment of TAG2 is not necessary. Also, the adjustment of measurement loop TAG3 (tal pressure) must not be carried out if you only want know the level of TAG1. Often, the tal pressure is requested as measured value, if e.g. in a filling system, the filling pressure should be measured and controlled. In this case carry out the adjustment without medium in "bar. Adjustment Signal conditioning Scaling 0 corres ponds corres ponds 300 Decimal point 888,8 prop.

In the menu item "Decimal point you determine the position of the decimal point. In the next menu item "prop. you get a choice of parameters: push [+] or [ ] select percent, mass, volume, pressure etc. and save with [OK]. According this adjustment, the menu item "Unit provides a new choice, e.g. m, dm, cm, mm, ft, yd and in, if you have selected the parameter "Height (compare chapter "8 Measuring results and units ). 0 corres ponds 1500 Set the number 1500 (with keys [+], [ ] and [OK]) in this menu item.

Scaling Lin. curve linear Integr ation time s 0 If the integration time is set 0 s (facry setting), each quick change of the product surface (e.g. waves) will be immediately detected and interpreted as level change. All output values of VEGAMET will follow the wave movements. To avoid this, the integration time can be increased (max. 600 s are possible with VEGAMET). The higher the time setting, the slower the measurement reacts. After a linearisation, the requested output can be assigned the linearised value in the menu range "Parameter adjustment outputs (menu items "prop. and "Unit ). VEGAMET
