Page 5: Overview
XNX Transmitter Sensor A Safety Integrity Level-certified system can detect the majority of safe and unsafe failures. XNX is SIL 2 capable per IEC 61508. XNX IR Personality IR sensor Table 1 board is SIL 3 capable in a redundant system per IEC 61508. -
Page 6: Safety Parameters
The safety parameters listed below are a combination of the main board, personality board, and sensor. These numbers were provided by TUV in report 968/EZ 319.07/20. For safety parameters of the individual sensors, refer to the XNX Safety Parameters For Sensors white paper. -

4690.21 *This rating is highest achievable SIL level the XNX, Searchpoint Optima Plus gas detection system can achieve as standalone safety devices. In more complex safety system the above values are the safety parameters of XNX and Optima gas detection system required to determine the acceptance of the complete safety function (i.e., all safety parameters, safety architecture, etc.) as required by IEC 61508 and IEC 61511. -

(required if the current output of zero gas and/or values when exiting the Test Menu. For more information on setting span gas calibration had to be changed) the mA output levels for normal operation, see mA Levels in the XNX 5.3 Tolerance of Output Current Levels Technical Manual. -
Page 9: Zero Gas Ma Output
The following section outlines the steps for calibrating the attached Example: 100% of full gas concentration is equivalent to XNX sensors. For calibration information for specific sensors, refer 20.0 mA. If 75% of the full scale gas concentration is applied, to the XNX Technical Manual. -

If the Span Calibration is skipped, the Gas Calibration screen increases, the values displayed will reflect the changing displays. concentration. When the concentration values are stable select to allow the XNX to calculate the zero adjustment. ✓ Selecting will return to the Gas Calibration Menu. ✖... -
