6.4 Setup procedureAfter connecting VEGAFLEX 65 to power supply or after avoltage recurrence, the instrument carries out a self-check forapprox. 30 seconds:l Internal check of the electronicsl Indication of the instrument type, the firmware as well asthe sensor TAGs (sensor designation)l Output signal jumps briefly (approx. 10 seconds) to the setfault currentThen the corresponding current is outputted to the cable (thevalue corresponds to the actual level as well as the settingsalready carried out, e.g. factory setting).In HART-Multidrop mode (several sensors on one input) theaddress must be set before continuing with the parameteradjustment. You will find a detailed description in the operatinginstructions manual "Indicating and adjustment module" or inthe online help of PACTware or DTM.HART modeStandardAddress 0As VEGAFLEX 65 is a distance measuring instrument, thedistance from the sensor to the product surface is measured.To have the real product level displayed, an allocation of themeasured distance to the percentage height must be made. Tocarry out this adjustment, the distance is entered with full andempty vessel. If these values are not known, an adjustmentwith the distance values, e.g. 10 % and 90 % is also possible.Starting point for these distance specifications is always theseal surface of the thread or flange. With these settings, thereal level is calculated. Furthermore the operating range of thesensor is limited from maximum to the required range.The real product level during this adjustment is not important,because the min./max. adjustment is always carried outwithout changing the product level. These settings can bemade ahead of time without the instrument having to beinstalled.In the main menu item "Basic adjustment", the individualsubmenu items should be selected one after the other andprovided with the correct parameter values.Switch on phaseAddress setting HART-MultidropParameter adjustmentVEGAFLEX 65 • 4 … 20 mA/HART 276 Set up with the indicating and adjustment module PLICSCOM31845-EN-080716
