Wiring and Sensor Connections
The XNX Universal Transmitter incorporates five threaded cable/conduit entries for convenient wiring and sensor integration. Before commencing any wiring, ensure the power supply is disconnected to prevent electrical shock or damage to the equipment. Carefully route the wires, avoiding sharp bends or kinks that could compromise the connection’s integrity. Use appropriate cable glands and sealing materials to ensure a watertight and environmentally protected seal for each entry point. Refer to the wiring diagram specific to your chosen sensor and configuration; Connect the sensor wires to the designated terminals, ensuring proper polarity and secure connections. For multi-node wiring, utilize the included terminal block jumpers to establish electrical continuity without needing the Personality Board. Install jumpers between pins 1 and 2, and pins 3 and 4, for proper operation. After completing the wiring, double-check all connections for tightness and correct polarity. Ensure the wiring is neatly organized and secured to avoid accidental disconnections. If using a remote mount kit, follow the instructions provided with that accessory. Improper wiring can lead to malfunction, so meticulous attention to detail is crucial. Always consult the provided schematics and adhere to safety guidelines throughout the process. Once wiring is complete, carefully reassemble the transmitter housing.
Configuring the Transmitter
Configuring the XNX Transmitter
Configuring the XNX Universal Transmitter involves setting parameters such as sensor type, calibration data, alarm thresholds, and communication protocols. Access the configuration menu using the dedicated interface, typically a keypad and display integrated into the transmitter housing or through a connected PC interface. The specific steps may vary depending on the transmitter’s firmware version and the connected sensor type. Consult the detailed instructions provided in the XNX Universal Transmitter Resource CD (Honeywell part number 1998-0748) for comprehensive guidance. Begin by selecting the appropriate sensor type from the pre-programmed options list within the configuration menu. Next, input the calibration data obtained during the sensor calibration procedure. This data ensures accurate gas concentration readings. Carefully set the alarm thresholds for both high and low gas concentration levels to trigger appropriate alerts. Configure the communication settings, such as the communication protocol (e.g., Modbus, Profibus), baud rate, and address, to establish proper communication with the host system. After making all the necessary settings, thoroughly review the configured parameters before saving them to the transmitter’s memory. Incorrect settings can compromise the performance of the gas detection system. Following this process ensures accurate operation and reliable performance of the XNX Universal Transmitter.
Calibration and Testing
Calibration of the XNX Universal Transmitter is crucial for accurate gas detection. This involves using calibrated gas mixtures to verify the sensor’s response and adjust its readings. The process typically requires specialized equipment and adherence to the manufacturer’s instructions, which are detailed in the accompanying documentation (Honeywell part number 1998-0748). Before initiating calibration, ensure the transmitter is properly mounted, wired, and configured. Use only calibrated gas mixtures with known concentrations, following safety guidelines for handling such materials. The calibration procedure often involves introducing the calibrated gas into the sensor chamber, observing the transmitter’s response, and adjusting the calibration settings as needed. After calibration, a thorough functional test is essential to validate the transmitter’s performance. This involves checking the response time, alarm thresholds, and overall accuracy of the gas concentration readings. The test should be conducted under various conditions, simulating real-world scenarios. Document all calibration and testing results for future reference and maintenance purposes. Regular calibration and testing maintain the accuracy and reliability of the XNX Universal Transmitter, ensuring safety and optimal performance.
Relay Board Installation (Optional)
The optional XNX Relay Board enhances the XNX Universal Transmitter’s functionality by providing three form C contacts for alarm and fault indication. Installation involves carefully inserting the relay board into the designated slot within the transmitter housing. Refer to the detailed diagrams and instructions within the XNX Relay Board Installation Guide for precise placement and connection points. Ensure the board is firmly seated to guarantee proper electrical contact. Wiring the relay board requires connecting the contacts to external alarm systems or other devices requiring signal relaying. Consult the wiring diagrams to correctly connect the alarm and fault contacts to the appropriate terminals. Use appropriately sized wires and follow all safety precautions. After installation, verify the relay board’s functionality by testing the alarm and fault signals. This ensures that the relay board operates correctly and triggers the external devices as intended.
