72 For Your Safety2.2 Proper Use - Conditions of UseThe Lambda Transmitter LT2 in combination with the Lambda Probe LS2-K, is a universal sys-tem for a direct detection of combustible gas constituents (CO/H 2), displayed as an equivalentof CO (COe ) in combustion systems in superstoichiometric range ( > 1).The system is designed for semi-automatic calibration with air and test gas.If the system should be used in a different way and the device function can not be accuratelydetermined for this application, you must consult the manufacturer before.PrerequisitesAll planning, mounting, installation, commissioning, maintenance, and repair work must becarried out by adequately trained personnel only and checked by experts.Correct handlingin particular, it is necessary to ensure that• the application must conform to the technical data and details of the permitted use, termsand conditions with regards to mounting, connection, environment and operation (to betaken from order documents, device’s user information, rating plat, etc) as well as the de-livered documentation• the local regulations and facility-specific and technical hazards must be noted and fol-lowed.• all necessary measures are taken to ensure value conservation, e.g. for transport andstorage as well as maintenance and inspection.Observing the operating instructionIntended use also includes:• Observing all the information in the operating instructions.• Carrying out all inspection and maintenance work.2.3 Permissible UsersQualified personnelThe person responsible for safety absolutely must guarantee that• only qualified personnel perform work on the system parts.Due to their training, education, experience, or instruction and due to their knowledge ofpertinent standards, provisions, accident prevention regulations, and system conditions,qualified personnel are authorized to perform these tasks by the person responsible forthe safety of people and the system. It is decisive that this personnel must be able to rec-ognise and prevent risks on time.Experts are considered to be people according to DIN VDE 0105 or IEC 364 or directlycomparable standards like DIN 0832.• These persons must have access to the provided operating manual and any pertinent or-der-related documentation during all work and observe these documents within the scopeof preventing risks and damage.
