Page 16
Safety instructions 2.2 Prerequisites for safe use WARNING Toxic and/or corrosive gases When measuring toxic or corrosive gases, it could occur that sample gas accumulates in the analyzer because of leaks in the gas path. To prevent the danger of poisoning or damage to parts of the analyzer, the analyzer must be purged.
Safety instructions 2.3 Analyzers in biogas plants outside the hazardous area WARNING Incorrect disassembly The following risks may result from incorrect disassembly: - Injury through electric shock - Risk through emerging media when connected to the process - Risk of explosion in hazardous area In order to disassemble correctly, observe the following: •...
Safety instructions 2.4 Analyzers in hazardous areas DANGER Explosion hazard When the device is used in biogas plants, you should expect that the sample gas will contain methane (CH ), which forms explosive mixtures with oxygen or air in certain concentrations. These conditions might occur under certain operating states of the plant.
Safety instructions 2.4 Analyzers in hazardous areas 2.4.2 ULTRAMAT 23 CSA general The device is suitable for installation in devices which are permitted by CSA. 2.4.3 ULTRAMAT 23 CSA with option E21 The sample gas exhaust lines must terminate outside the hazardous area at a harmless location. The sample gas exhaust line can also be returned to the sampling point.
Safety instructions 2.5 Measurement of oxygen in hydrogen with Oxymat 6E 2.4.5 CALOMAT 6E DANGER Explosion hazard Frequently or permanently explosive gas mixtures must not be connected. Rarely or occasionally explosive gas mixtures may be connected in accordance with the special conditions specified in the corresponding certificates.
Page 21
Safety instructions 2.5 Measurement of oxygen in hydrogen with Oxymat 6E DANGER Danger of explosion! Measuring explosive gas mixtures with OXYMAT 6 Non-explosive sample gases and gas mixtures below the LEL may be introduced into the OXYMAT 6. Flame arrestors are not required. However, it must be guaranteed that the sample gas in the gas path (containment system, CS) always remains below the lower explosive limit! Rarely or occasionally explosive gas mixtures must only be introduced into the gas analyzer if the inputs and outputs for sample gas have been each provided with a flame arrestor.
Safety instructions 2.6 Measurement of hydrogen in oxygen with Calomat 6E Measurement of hydrogen in oxygen with Calomat 6E NOTICE Explosive gas mixtures Gas mixtures of hydrogen H in oxygen O are explosive in a wide range. At an atmospheric pressure of 1000 hPa and 20 °C ambient temperature, the lower explosive limit (LEL) lies at 4 % in O , the upper explosive limit (UEL) at 95.2 % H in O...
Safety instructions 2.6 Measurement of hydrogen in oxygen with Calomat 6E The device must be set up in a well ventilated place so that an explosive mixture cannot build up in the device environment. If the device is installed in a cabinet, it must be insured through suitable measures that the ventilation rate in this cabinet amounts to at least 1/h (exhaust air at cabinet cover, supply air at cabinet bottom).
Safety instructions 2.6 Measurement of hydrogen in oxygen with Calomat 6E 2.6.2 Limit Limit A limit that lies at 1 % O is set to ensure that the measuring values lie below the lower explosive limit (LEL) during measuring operation. This corresponds to approx. 25 % of the LEL. Exceeding of the limit is signaled at Relay 4.
Assembly/installation Safety information WARNING Wetted parts unsuitable for the process media Danger of injury or damage to device. Hot, toxic and corrosive media could be released if the process medium is unsuitable for the wetted parts. • Ensure that the material of the device parts wetted by the process medium is suitable for the medium.
Assembly/installation 3.3 Analyzers in hazardous areas WARNING Insufficient ventilation The device may overheat or start burning in the case of insufficient ventilation. • Ensure sufficient ventilation between the devices when installing in control cabinets. The heat sinks at the rear must remain free for air circulation. •...
