Page 6: Preliminary Information
Preliminary information The SmArtGas 4 gas detector is a device designed as a components of the Gas Safety System dedicated for operation in areas with potentially explosive atmospheres and under heavy-duty industrial conditions with broad range of ambient parameters variations (high temperatures, corrosive gases, moisture and dust). The key feature of the device, indispensable to guarantee safe and unproblematic operation is its conformity to requirements of the ATEX EU Directive and IECEx standards. -
Page 7: Marking Of Explosion Protection
www.atestgaz.pl Basic functionalities Non-invasive calibration and configuration – the gas detector can be calibrated and parametrized (e.g. the alarm thresholds) in hazardous areas without opening the housing or turning off other parts of the gas safety system (only for RS-485). Ability to calibrate gas detectors mounted at inaccessible locations. -
Page 8: Cable Glands And Blanking Plugs
www.atestgaz.pl Cable glands and blanking plugs The cable gland and blanking plug are replaceable elements. To select spare ones please obey the following rules: ATEX and IECEx certificates, degree of explosion protection (Ex code) – no worse than the detector (see Table 11), operating temperature range (see Table 11), appropriate mounting thread –... -
Page 9: Detected Gases
www.atestgaz.pl Mode Description Lock Gas concentration is above the overload value (the default value is 100% LEL). The detector is locked (see Appendix [3]) – the last value of the concentration is shut. The detector does not make measurements. It is possible to unlock the condition by means of sending the applicable command from the control unit or from the superior system. -
Page 10: Safety
www.atestgaz.pl The calibration procedure is described in Section 6.6.2.2. In addition, the calibration procedure for gas detectors furnished with the FL.C head must be carried out with consideration of the following constraints: flow rate of a reference gas must be not less than 0.5 ltr./min, wind velocity nearby the detector must not exceed 0.5 m/s. -
