Any values not confirmed with [OK] will not besaved.5.4 Setup procedureAfter VEGAPULS 62 is connected to power supply orafter voltage recurrence, the instrument carries out aself-test for approx. 30 seconds. The following steps arecarried out:l internal check of the electronicsl indication of the instrument type, the firmware versionas well as the sensor TAGs (sensor name)l Output signal jumps briefly (approx. 10 seconds) tothe set interference current.Then the actual measured value is displayed and thecorresponding current is transmitted to the cable1)In HART-Multidrop mode (several sensors on one input)the address must be set before continuing with theparameter adjustment. You will find a detailed descrip-tion in the operating instructions manual of PLICSCOMor in the online help of PACTware™ or DTM.HART modeStandardAddress 0Because VEGAPULS 62 is a distance measuringinstrument, the distance from the sensor to the productsurface is measured. In order to have the actual leveldisplayed, an allocation of the measured distance to thepercentage height must be carried out. To make thisadjustment, the full and empty distances in the vesselare entered. If these values are not known, it is alsopossible to carry out the adjustment with other distan-ces, e.g. 10 % and 90 %. Starting point of these distancevalues is always the seal surface of the thread or flange.The actual level is then calculated on the basis of these1) The values correspond to the actual level as well as to the settingsalready carried out, e.g. default setting.Switch on phaseAddress setting HART-MultidropParameter adjustment36 VEGAPULS 62 - 4 ... 20 mA/HARTSetup with the indicating and adjustment module PLICSCOM28435-EN-050211
