6.4 Setup procedureAfter VEGACAL 62 is connected to voltage supply or after voltagerecurrence, the instrument carries out a self-check for approx. 30seconds. The following steps are carried out:l Internal check of the electronicsl Indication of the instrument type, the firmware as well as thesensor TAGs (sensor designation)l Status byte goes briefly to fault valueThen the current measured value will be displayed and thecorresponding digital output signal will be outputted to the cable.1)Before starting the actual parameter adjustment of a Profibus PAsensor, the address setting must first be carried out. You will find adetailed description in the operating instructions manual of theindicating and adjustment module or in the online help of PACTware orDTM.VEGACAL 62 measures the capacitance of the respective product. Todisplay the actual level of the product, an allocation of the measuredcapacitance to the percentage height must be carried out. For thisadjustment, the capacitance is entered with emptied and filled vessel.If the vessel cannot be emptied or filled completely, you can carry outthe adjustment also with two known levels - for example with 10 % and90 %. The difference between the empty and full adjustment valuesshould be as large as possible.The actual level can then be calculated on the basis of these settings.VEGACAL 62 must be installed. A change of level is necessary for thisadjustment.In the main menu item "Basic adjustment", the individual submenuitems should be selected one after the other and provided with thecorrect parameter values.Tip:If the indicating and adjustment module remains on the probe as adisplay, we recommend saving the sensor data in the indicating andadjustment module.Use the function "Copy sensor data".Start your parameter adjustment with the following menu items of thebasic adjustment:To be on the safe side, note the adjustment values for full and empty. Ifan adjustment procedure fails, it is not necessary to again carry out alevel change.1) The values correspond to the actual measured level as well as to the set-tings already carried out, e.g. default setting.Switch on phaseAddress settingParameter adjustmentCarrying out min. ad-justmentVEGACAL 62 • Profibus PA 276 Set up with the indicating and adjustment module PLICSCOM30025-EN-090603
