Installation Guidelines

• Mount the XNX-AMSV-NNIV1 vertically on a flat surface using the integral brackets.
• Connect the 5 x M25 entries with appropriate cable glands for IP66 protection.
• Wire the 4-20mA loop with HART® to your control system or PLC.
• Attach the compatible mV sensor (MPD, Sensepoint, or Model 705) to the interface.
• Apply power (24V DC nominal) and verify the output signal before final calibration.
• Perform a zero and span calibration using certified methane gas standards.

Frequently Asked Questions (FAQ)

• Is this transmitter compatible with 3-wire mV sensors? Yes, the mV version (Personality V) supports 3-wire milli-Volt sensors like MPD and Sensepoint.
• Can I use this for other gases besides methane? The IR sensor is factory-set for methane. For other gases, please contact Honeywell for alternative range options.
• What is the maximum cable length for the 4-20mA output? With HART®, we recommend up to 1000 meters using shielded twisted-pair cable.
• Does the transmitter support SIL certification? The XNX-AMSV-NNIV1 meets SIL 2 requirements for functional safety applications.
• What is the ambient humidity tolerance? It operates from 0 to 95% RH non-condensing.
• How do I perform a zero adjustment? Use the magnetic switch or HART® communicator to initiate zero calibration in fresh air.
