FlexView BattTemp Description CombiTemp comprises a series of basic elements which can be combined to various temperature sensors and transmitters. Being a building block system CombiTemp offers a great fl exibility in respect to modifi cation, service and maintenance. The basic components in the system are: Housing: DIN-formB or Ø80mm stainless steel Process connection: Refer to the data sheet FlexTop transmitters: 2201, 2211, 2221, 2231 FlexView ma LC-display BattTemp, Battery operated Pt100 LC-display The parts can be assembled by the user or delivered assembled and calibrated, if relevant. However, an Ex ia or Ex n approved product will always be assembled at the factory. Please refer to the relevant data sheets and installation manuals for each product: Product Data Sheet Manual CombiTemp This manual FlexTop FlexTop FlexTop FlexTop FlexView BattTemp All documentation can be found at This Ex-approved product is manufactured by: Baumer A/S Jacob Knudsens Vej 14 DK-8230 Aabyhoej Denmark Page 1

In order to main tain this condition and to ensure safe op er a tion, 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 per son al injury or substantial damage to property. The product must be op er at ed by trained staff. Correct and safe operation of this equipment is de pend ent on proper transport, storage, installation and op er a tion. All electrical wiring must conform to local stand ards. In order to prevent stray elec tri cal radiation, we rec om mend twisted and shielded input cables, as also to keep power sup ply cables separated from the input cables. The con nec tion must be made ac cord ing to the connecting di a grams. Before switching on the power supply take care that other equip ment is not af fect ed. Ensure that the supply voltage and the conditions in the environment comply with the spec i fi ca tion of the de vice. Before switching off the supply voltage check the possible effects on other equipment and the processing system. WARNING For electrical installation and com mis sion ing of explosion protected devices, the data given in the con form i ty cer tifi cate as also the local reg u la tions for installation of elec tri cal apparatus within explosion protect ed areas must be considered. The intrinsically safe versions can be mounted in the explosion hazarded area according to its spec i fi ca tion only con nect ed to a certifi ed intrinsically safe supply loop with the corre spond ing electrical values. Sensor tube and connection Material Acid-proof, stainless steel (AISI 316L/W ) Media pressure Max. 16 bar Time constant t 0.5 See table below Mechanical tolerances ISO 2768-m Sensor element Sensor type Pt100, Class A or B Pt1000, Class B Accuracy DIN/EN/IEC /1 DIN B: ±( x t) C 1/3 DIN B: +1/3 x ( x t) C 1/6 DIN B: +1/6 x ( x t) C 1/1 DIN A: +( x t) C Ex-Application - Configuration Valid for FlexTop 2201 / 2211 / 2221 and FlexView: None of the two types of FlexProgrammer confi guring unit must be connected to the FlexView within the hazardous area. Confi guring procedure: a) Disconnect mains from the ma loop circuit. b) Disconnect the product from the circuitry within the hazardous area. c) Bring the product to the safe area. d) Connect the FlexProgrammer and perform the confi guring session. e) Re-install the product in the hazardous area. f) Connect the power supply to the circuit. Valid for FlexTop 2221 only: Confi guration of the FlexTop2221 can be made within the hazardous area by means of a handheld HART confi gurator, providing the precautions and guidelines described in the product s manual are observed. Valid for FlexTop 2231 only: Confi guration of the FlexTop2231 can be made within the hazardous area by means of a Profi bus PA confi gurator, providing the precautions and guidelines described in the product s manual are observed. WARNING This product contains no replaceable parts. In case of malfunction the product must be shipped to Baumer for repair. WARNING Products with painted and/or plastic surfaces (e.g. display) imply a risk of electrostatic charging. To prevent electrostatic hazard - do only clean with a moist cloth. After mounting the device - do check that the housing has a ground potential. Page 2
