During work on and with the device the required personal protective equipment must always be worn. Appropriate use The VEGABAR 82 is a pressure transmitter for process pressure and hydrostatic level measurement. You can find detailed information about the area of application in chapter "Product description". Operational reliability is ensured only if the instrument is properly used according to the specifications in the operating instructions manual as well as possible supplementary instructions.
The instrument meets the specifications of IEC 61508: 2010 (Edi- tion 2). It is qualified for single-channel operation up to SIL2. The instrument can be used homogeneously redundant up to SIL3 in multi-channel architecture with HFT 1. Permissible process pressure The permissible process pressure is specified on the type label with "Process pressure", see chapter "Configuration". For safety reasons, this range may not be exceeded. This applies even if a measuring cell with a measuring range (order-related) higher than the permissible pressure range of the process fitting is installed. VEGABAR 82 • 4 … 20 mA/HART...

The instrument is shipped in locked condition. To prevent unintentional or unauthorized adjustment, the instrument is protected (locked) against all parameter changes while in normal operating condition. For each parameter change you have to enter the PIN of the instru- ment. In delivery status, the PIN is "0000". VEGABAR 82 • 4 … 20 mA/HART...

4. Depending on the application, carry out the adjustment e.g. in the menu items "Min. adjustment" and "Max. adjustment". Parameterization example VEGABAR 82 always measures pressure independently of the pro- cess variable selected in the menu item "Application". To output the selected process variable correctly, an allocation of the output signal to 0 % and 100 % must be carried out (adjustment).

3. Serial number acknowledgement Afterwards you confirm that the serial number of your instrument was carried over correctly. This is used to check device communication. 4. Verify parameters Confirm the modified values one after the other. If the described process of parameter adjustment was run through completely and correctly, the instrument will be locked and hence ready for operation. VEGABAR 82 • 4 … 20 mA/HART...
