The electron-ics modules are adapted to the respective sensor and differ in signaloutput or voltage supply.The new electronics module must be loaded with the default settingsof the sensor. These are the options:• In the factory• Or on site by the userIn both cases, the serial number of the sensor is needed. The serialnumbers are stated on the type label of the instrument, on the insideof the housing as well as on the delivery note.When loading on site, the order data must first be downloaded fromthe Internet (see operating instructions "Electronics module").Caution:All application-specific settings must be entered again. That's why youhave to carry out a fresh setup after exchanging the electronics.If you saved the parameter settings during the first setup of the sen-sor, you can transfer them to the replacement electronics module. Afresh setup is then not necessary.9.6 Software updateThe device software can be updated in the following ways:• Interface adapter VEGACONNECT• HART signal• BluetoothDepending on the method, the following components are required:• Instrument• Voltage supply• Interface adapter VEGACONNECT• Display and adjustment module PLICSCOM with Bluetooth func-tion• PC with PACTware/DTM and Bluetooth USB adapter• Current instrument software as fileYou can find the current instrument software as well as detailedinformation on the procedure in the download area of our homepage:www.vega.com.Caution:Instruments with approvals can be bound to certain software versions.Therefore make sure that the approval is still effective after a softwareupdate is carried out.You can find detailed information in the download area atwww.vega.com.
