In case the temperature sensors used by the operator of the measuring devices are interchangeable, they must have their own MID-conformity label. Ambient conditions / influencing variables: - Climatic: max. ambient temperature 55 C, min. ambient temperature 5 C, Humidity class: IP 65 - Electro-magnetic class: E1 - Mechanical class: M1 - Pressure class: PN/PS: 10/16/25 bar 3.2 Further operating conditions Auxiliary energy: optional mains connection 115 V/230 V AC 50 Hz or battery 3.6 V or external supply 12 V to 24 V or 24 V AC 4 Interfaces and compatibility conditions The length of the connecting cables of the optional temperature sensors Pt 100 or Pt 500 in two-wire technology should not exceed 15 m each for the supply and the return line; in four-wire technology they should not exceed 50 m, optionally shielded or unshielded. The cable cross-sections have to be in line with EN , section 3. The length of the shielded connecting cable to the flow sensor must not exceed 10 m. In case the temperature sensors used in the measuring devices are interchangeable, they have to be connected to the connecting points in accordance with the installation and operating instruction (see section 2). Attention has to be paid that their electrical compatibility Pt 100 resp. Pt 500 is in line with the integrator.

9 Seite 9 von 29 Seiten Page 9 of 29 pages The compatibility of the pulse value and the nominal flow value q p between integrator, measuring head and base part has to be checked in case interchangeable components are used at the place of installation. See further specifications in section 5. 5 Requirements for production, starting of operation and use 5.1 Production requirements To ensure the compliance with the error limits acc. to MI-004, the production and calibration process has to be done in accordance with the specifications in section 2.6b. The length of the connecting cables of the temperature sensors in two-wire technology should not exceed 15 m for the supply and return line. In four-wire technology they each should not exceed 50 m, shielded or unshielded. The cable cross-sections have to be in line with EN , section 3. The length of the shielded connecting cable to the flow sensor must not exceed 10 m. The following user information has to be given in the installation instruction: Depending on the date of delivery of the heat meters and acc. to the version of the certificate which depends on the date of issue of the EC type-examination certificate, i.e. acc. to the original certificate of March 15, 2007, exclusively with permanently installed electric connecting cable between measuring head electronics of the flow sensor and integrator or acc. to the first revision of April 15, 2009, certified also with separable connecting cable, the electrical connecting areas have to be secured with user seals in accordance with the approval. In the installation instruction, mention has to be made for the user that he is not allowed to freely exchange the measuring head of the oscillating flow sensor of the base part that remains in the tubing system if a so-called user-defined volume adjustment has been carried out in the integrator 531. The user of the measuring device has to be informed on how he can identify and retrace a user-defined adjustment in the integrator at the place of installation, e.g. by displaying the requested data. If, however, during the MID-conformity management acc. to module F or a domestic re-calibration a user-defined volume adjustment is carried out, the measuring head and the integrator constitute a metrologically connected entity. In this case, a captive note, e.g. Attention: connection only approved with measuring head No. xyz, has to be attached to the integrator. Heat meters with permanently connected temperature sensors and installed remote read-out modules, see section 4, have to be protected against manipulation, see specifications in section 7, that the measuring devices can only be opened by damaging the safety seals. The connecting areas of interchangeable conformity-certified temperature sensor pairs as well as interchangeable remote read-out modules have to be furnished with

10 Seite 10 von 29 Seiten Page 10 of 29 pages safety measures (see section 4 and 2.7) for the user of the measuring devices acc. to the specifications see section 7. When mounting the measuring head (piezo sensing electronics) on the base part, the specified torques (see specifications in section 2.6b) have to be followed. The shielded connection cable to the flow sensor always has to be grounded with strain relief. If the heat meter is intended for symmetrical installation of the temperature sensor pair with protection pockets, the permanently connected temperature sensors must have a separate EC type-examination certificate also including the conformity-tested protection pockets. If, however, the sensor is connected permanently, the sensor does not have an EC-label. In any case, when supplying the protection pockets, they have to be stated on a list that is enclosed in the shipment to make sure that the user can clearly assign them to the measuring device or they have to be marked accordingly so that the corresponding heat meter can be identified. 5.2 Requirements for the start of operation After the installation and the functional test acc. to the installation instruction, every device has to be equipped with the security measures mentioned in the specifications, see section 7. Each device has to be supplied with an installation and operating instruction describing the start of operation. When mounting the measuring head (piezo sensing electronics) on the base part in the field, the specified torques stated in the installation instruction have to be followed. The seals have to be replaced after every disassembly. The shielded connection cable to the flow sensor always has to be grounded with strain relief! The length of the connecting cables of the temperature sensors in two-wire technology must not exceed 15 m for the supply and return line, see section 4, and 50 m in four-wire technology. With regard to the cable cross-sections, EN , section 3, applies. The length of the shielded connecting cable to the flow sensor must not exceed 10 m. The specifications made in the installation and operating instruction supplied with every device have to be adhered to. After electrical connection of the flow sensor to the integrator, the terminals 9, 10, 11 have to be secured by the supplied user seal. 5.3 Requirements for the use The user is asked to follow the operating conditions mentioned below (also listed in the installation and operating instruction): The temperature sensors have to be installed symmetrically in the supply and return line; preferably directly. If protection pockets are used, they have to be tested especially for their conformity with the temperature sensor used. The supply and

11 Seite 11 von 29 Seiten Page 11 of 29 pages return flow sensors with protection pockets must be fully inserted to the bottom of the pocket. Installation points in the flow sensor can be used when installing the temperature sensor symmetrically. If permanently connected temperature sensors are used, the connection cables must not be shortened. If interchangeable and conformity-certified temperature sensors are used, the length of the connection cables for the supply and return line each is 15 m in two-wire technology, 50 m in four-wire technology, the same length for supply and return line. The cable cross-sections have to be in line with EN They are connected to the marked connecting points taking into account the electrical compatibility Pt 100 resp. Pt 500 of the integrator. Subsequently, security measures, see section 7, have to be carried out. Up to a maximum nominal flow of q p 10 m³/h, an undisturbed straight inlet and outlet zone is not necessary. If the nominal flow exceeds q p 15 m³/h, an undisturbed, straight inlet and outlet zone of each 3 DN has to be guaranteed. The battery has to be chosen in a way that the supply of auxiliary energy is guaranteed over the whole service life plus 1 year of storage. Specifications on the measurement stability are made on condition that the water composition is in line with the AGFW-requirements FW 510. If the composition is not in line with the specification, the measuring device has to be disassembled and submitted to periodic maintenance acc. to the specifications in section 6.1. The temperature sensors have to be protected with user seals to avoid dismantling. 6 Check of devices in operation The electrical connections of the components between the integrator and the measuring head have to be done differently in accordance with the date of issue of the EC type-examination certificate, see section 5.1, i.e. according to the original certificate of March 15, 2007 inseparable resp. according to the first revision of April 15, 2009 optionally separable at the place of location. 6.1 Documents for the test (see annex) Test procedure Superstatic 440 and maintenance directive of June 21, 2010

12 Seite 12 von 29 Seiten Page 12 of 29 pages 6.2 Test equipment With regard to EN , no special test equipment is necessary. However special test equipment and procedures may be necessary according to the documents referred into section Identification Hardware: The hardware type is permanently stored in the EEPROM. Software: The number of the version can be called on the display: 4.x. for the integrator upper and base part A CRC-sign is used for the whole software including the metrological part and application part. With regard to the main metrological relevant components, the heat meter corresponds to the measuring device with the number Z 22.12/03.06 approved in accordance with the homologation for Germany, however the range of functions has been extended and the standards of the directive 2004/22/EG are met. 6.4 Metrological test According to the specifications in the documents, see section 6.1, the integrator is checked by simulating the supply and return line temperatures with precision resistances following the basic value characteristics acc. to EN 60751, section 5 of EN ; field of application: heating. The signals of the flow sensors are simulated electrically. The values of the high resolution display have to be in line with the energy display in normal condition. This test after start of production can be omitted in case of a testintegrated query using a check sum (CRC-sign). 7 Security measures Security measures: Test procedure Superstatic 440 DE , page 17 and installation and operating instruction Installation of Superstatic 440 DE EN MID , page 7 and 12 Depending on the delivery date of the heat meter version, see section 5.1, the connection cables between the integrator and the measuring head are submitted to a specific labeling obligation.
