Section 2.51 Gas Type Selection Process
Follow the XNX Universal Transmitter manual’s section 2.51 to identify the correct gas for your installation. The transmitter supports a wide range of combustible gases‚ each requiring a specific sensor and calibration curve. Begin by inspecting the sensor’s label or serial number‚ which indicates the target gas (e.g.‚ methane‚ propane‚ hydrogen sulfide). If the sensor is not pre‑programmed‚ use the XNX configuration software to input the gas type‚ ensuring the device’s internal lookup table matches the selected gas. After confirming the gas‚ the transmitter automatically adjusts its detection algorithm and alarm thresholds to the appropriate sensitivity range. For gases with low detection limits‚ the software will enable high‑resolution mode; for high‑pressure gases‚ it will switch to a pressure‑compensated mode; It is essential to verify the gas type before any calibration; an incorrect selection can lead to false alarms or missed detections. Once the gas is set‚ document the choice in the installation log and proceed to the first‑start procedure in section 4‚ where alarm levels and ranges are configured. Always double‑check the gas type after firmware updates‚ as new revisions may alter sensor compatibility. If you encounter a sensor that does not match any listed gas‚ contact Honeywell support for a replacement or a custom calibration. Proper gas selection is the foundation of reliable safety monitoring and ensures compliance with ATEX and IECEx regulations for hazardous environments. Review the manual for updates now.
Alarm Levels & Calibration
The XNX transmitter allows setting alarm thresholds via the Quick Start Manual. Configure low‚ medium‚ and high alarm levels in the configuration menu‚ then perform a 6.1 calibration to ensure accurate detection. Verify settings with the built‑in test function!!
Setting Alarm Thresholds and Performing 6.1 Calibration
To configure the XNX Universal Transmitter’s alarm thresholds‚ first access the device’s configuration menu via the serial interface or the web portal. Navigate to the “Alarm Settings” section‚ where you can set the low‚ medium‚ and high alarm limits in parts per million (ppm) or percent of the lower explosive limit (LEL). The manual recommends starting with the manufacturer’s default values and adjusting based on the specific process conditions. After setting the thresholds‚ save the configuration and reboot the unit to apply changes. Calibration is performed using the 6.1 procedure described in the technical manual. This involves supplying a known gas concentration to the sensor‚ typically a 10 % LEL standard‚ and verifying the transmitter’s response. Use the calibration tool or a calibrated gas cylinder to introduce the test gas. Once the gas is stabilized‚ record the transmitter’s output on the display. If the reading deviates beyond the tolerance specified in the manual (usually ±5 % of the set point)‚ adjust the calibration factor until the output matches the reference value. Repeat the test at the high and low alarm points to ensure linearity across the measurement range. Document all calibration data in the maintenance log‚ noting the date‚ gas used‚ and any adjustments made. Regular calibration checks are essential for maintaining compliance with ATEX/IECEx safety standards and ensuring reliable alarm performance in hazardous environments.
During calibration‚ it is crucial to isolate the transmitter from ambient temperature fluctuations. Place the unit in a controlled environment‚ preferably at 20 °C‚ and allow a 15‑minute equilibration period before initiating the test. Temperature compensation is handled automatically by the XNX firmware‚ but manual verification can be performed by comparing the output at two temperatures‚ 0 °C and 40 °C‚ to confirm the temperature coefficient matches the specification. If discrepancies are observed‚ consult the troubleshooting section for potential sensor drift or wiring issues. Additionally‚ the manual advises performing a full calibration cycle at least once per month for critical safety applications‚ and quarterly for less critical installations. Maintain a calibration log with serial numbers‚ calibration dates‚ and the person responsible for the test. This log is required for audit purposes and to demonstrate compliance with industry regulations. Finally‚ after completing the calibration‚ run the self‑test routine to ensure the transmitter’s internal diagnostics are clear before returning the unit to service.
