You can find supplementary information in the corresponding, more detailed Operating Instructions Manual as well as the Safety Manual that comes with instruments with SIL qualification. These manuals are available in the download area of "www.vega.com". Operating instructions VEGABAR 87 - Modbus and Levelmaster protocol: Document-ID 46297 Editing status of the quick setup guide: 2019-04-02 3 1 For your safety VEGABAR 87 • Modbus and Levelmaster protocol 46330-EN-190404 1 For your safety 1.1 Authorised personnel All operations described in this documentation must be carried out only by trained, qualified personnel authorised by the plant operator. During work on and with the device, the required personal protective equipment must always be worn. 1.2 Appropriate use Model VEGABAR 87 is a pressure transmitter for level and gauge 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. 1.3 Warning about incorrect use Inappropriate or incorrect use of this product can give rise to applica- tion-specific hazards, e.g. vessel overfill through incorrect mounting or adjustment. Damage to property and persons or environmental contamination can result. Also, the protective characteristics of the instrument can be impaired. 1.4 General safety instructions This is a state-of-the-art instrument complying with all prevailing regulations and directives. The instrument must only be operated in a technically flawless and reliable condition. The operator is responsi- ble for the trouble-free operation of the instrument. When measuring aggressive or corrosive media that can cause a dangerous situation if the instrument malfunctions, the operator has to implement suitable measures to make sure the instrument is functioning properly. During the entire duration of use, the user is obliged to determine the compliance of the necessary occupational safety measures with the current valid rules and regulations and also take note of new regula- tions. The safety instructions in this operating instructions manual, the na- tional installation standards as well as the valid safety regulations and accident prevention rules must be observed by the user. For safety and warranty reasons, any invasive work on the device beyond that described in the operating instructions manual may be carried out only by personnel authorised by the manufacturer. Arbi- trary conversions or modifications are explicitly forbidden. For safety reasons, only the accessory specified by the manufacturer must be used. To avoid any danger, the safety approval markings and safety tips on the device must also be observed and their meaning read in this oper- ating instructions manual. 4 1 For your safety VEGABAR 87 • Modbus and Levelmaster protocol 46330-EN-190404 1.5 EU conformity The device fulfils the legal requirements of the applicable EU direc- tives. By affixing the CE marking, we confirm the conformity of the instrument with these directives. You can find the EU conformity declaration on our website under www.vega.com/downloads. 1.6 Permissible process conditions For safety reasons, the instrument must only be operated within the permissible process conditions. You can find detailed information on the process conditions in chapter "Technical data" as well as on the type label. The permissible process pressure range is specified on the type label with "MWP" (Maximum Working Pressure), see chapter "Configura- tion". 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. A temperature derating, e.g. with flanges, can limit the permissible process pressure range. 1.7 NAMUR recommendations NAMUR is the automation technology user association in the process industry in Germany. The published NAMUR recommendations are accepted as the standard in field instrumentation. The device fulfils the requirements of the following NAMUR recom- mendations: • NE 21 – Electromagnetic compatibility of equipment • NE 53 – Compatibility of field devices and display/adjustment components • NE 107 – Self-monitoring and diagnosis of field devices For further information see www.namur.de. 1.8 Environmental instructions Protection of the environment is one of our most important duties.
