3 1 About this document 1 About this document 1.1 Function This instructions manual provides the most important information of instruments according to "3-A Sanitary Standard for Sensors and Sensor Fittings and Connections, Number 74". 1.2 Scope These instructions apply to radar sensors VEGAPULS 63 with hygienic process fittings and seals. You can find the fittings chapter "Manufacturer declaration", instructions to the seals in chapter "Instrument versions". 3

4 2 3-A-Standards - Meaning and implementation Meaning of 3-A Use of instruments according to 3-A 2 3-A-Standards - Meaning and implementation The 3-A Sanitary Standards Incorporation issues hygienic standards giving specifications for the materials, the mechanical designs and the manufacturing methods. The organisation checks if the hygienic designs have been complied with. Conformity is checked by an independent third agency, CCE (Certified Conformance Evaluator). In case of conformity, 3-A SSI (Sanitary Standards, Incorporation) awards a symbol license for the 3-A logo. The use of instruments and components with the 3-A logo provides proof that the configuration was tested. The certificate always refers to a combination of sensor and process fitting. Both components of this combination must conform with 3-A. It looks like the following: The requirements for installations according to 3-A are much higher than those for standard applications. This applies especially to: Version of the housing (e.g. easy cleaning) Configuration of the process fitting (e.g. visibility of possible leakage) Seals (e.g. FDA and 3-A conformity, resistiveness) Installation position on the vessel (e.g. self-drainage) Cleaning, maintenance (intervals, methods) 4

5 3 Instrument versions Housing Process fittings Welded socket Seals 3 Instrument versions For use according to 3-A standard, the housing is preferably of stainless steel, electropolished (Z). On these instruments, e.g., the transition to the process fitting is shortened for better cleanability. This housing version is suitable for measurement loops with increased hygienic requirements and applications where a daily wet cleaning is required. As orientation, the definition of the zone division acc. to EHEDG is valid. If "3-A certification" is selected in the configurator, the housing will be marked with a "3-A" logo. The single chamber housing version stainless steel electropolished (8) can be used in applications with low hygienic requirements where for example an outside dry cleaning is sufficient. Only process fittings listed in chapter "Manufacturer declaration" may be used for installations according to 3-A standards. They meet the hygienic requirements of 3-A standards no. 63 and 74 including the requirement for self-drainage in case of a leak in the instrument seal. Only the welded sockets listed in chapter "Manufacturer declaration" may be used for installation according to 3-A standards. Only suitable, 3-A conform seals must be used for applications according to 3-A standards: 5

6 4 Mounting 4 Mounting Note the following items for a measuring point according to 3-A standard: All parts of the measuring point must be certified according to 3-A The sensor must be mounted vertically from top. The mounting position must enably the self-drainage of the sensor Welded connections must have a surface roughness 0.8 µm and must be free from any defects Welding sockets must be welded flush with the inside of the vessel 6

7 5 Maintenance, cleaning Maintenance Cleaning 5 Maintenance, cleaning According to 3-A standard no. 74, it is the responsibility of the user to ensure the hygienically safe condition of the sensor during its entire service life. This includes selecting the seal material according to 3-A standards. A leaky seal represents a hygienic risk. To avoid this, the seals should be replaced with new ones at regular intervals and the sensor checked for damage. The accessible surface must be cleaned carefully when the seal is exchanged. The user plans the intervals according to the process conditions and seal materials. The sensor should be kept clean by using validated, state-of-the-art cleaning processes. Success should be checked by dismounting the sensor. The user is responsible for ensuring that the seal material as well as the sensor itself are resistant to the medium and the cleaning process. Resistance lists as well as the technical data of the respective sensor can serve as a basis for selection. 7
