FlexBar HRT Pressure Transmitter Safety instructions This instrument is built and tested according to the current EU-directives and packed in technically safe condition. In order to maintain this condition and to ensure safe operation, the user must follow the hints and warnings given in this instruction. During the installation the valid national rules have to be observed. Ignoring the warnings may lead to severe personal injury or substantial damage to property. The product must be operated by trained staff. Correct and safe operation of this equipment is dependent on proper transport, storage, installation and operation. All electrical wiring must conform to local standards. In order to prevent stray electrical radiation, we recommend twisted and shielded input cables, as also to keep power supply cables separated from the input cables. The connection must be made according to the connecting diagrams. Before switching on the power supply take care that other equipment is not affected. Ensure that the supply voltage and the conditions in the environment comply with the specification of the device. Before switching off the supply voltage check the possible effects on other equipment and the processing system. WARNING For electrical installation and commissioning of explosion protected devices, the data given in the conformity cer tificate as also the local regulations for installation of electrical apparatus within explosion protected areas must be considered. The intrinsically safe versions can be mounted in the explosion hazarded area according to its specification only connected to a certified intrinsically safe supply loop with the corresponding electrical values.

Disposal of product and packing Installation procedure According to national laws or by returning to Baumer a) Remove protection-cap. b) Install FlexBar. (G1/2A versions: Tighten up at 20 Nm.) c) Configure Span by the FlexProgrammer or a HART configurator. d) Connect the power supply, press and hold the Auto Zero button or use the facility in the FlexProgrammer or the HART configurator. Adjusting the zero point With FlexBar HRT the electronic zero point can be adjusted from -10...10% of the total measuring range. Ex-Configuring Warnings None of the two types of FlexProgrammer configuring unit must be connected to the FlexBar HRT within the hazardous area. WARNING This product contains no replaceable parts. In case of malfunction the product must be shipped to Baumer for repair. Configuring procedure: a) Disconnect mains from the 4...20 mA loop circuit. b) Disconnect the FlexBar HRT from the circuitry within the hazardous area. c) Uninstall and bring the FlexBar HRT to the safe area. d) Connect the FlexProgrammer and perform the configuring session. e) Re-install the FlexBar HRT in the hazardous area. f) Connect the power supply to the circuit.
