Installation & Commissioning
Mounting: Use the four 3/4″ NPT entries for flexible conduit connections. Secure the transmitter to a flat surface. Ensure the sensor points downward for optimal gas detection.
Wiring: Connect the 4-20mA loop with HART® capability. Observe polarity and grounding per local codes. Use shielded cable for long runs.
Commissioning: Power up and allow 2 minutes warm-up. Perform a zero calibration in clean air. Use the magnetic switch for non-intrusive setup. The display shows real-time concentration and status.
Maintenance & Diagnostics
Diagnostic Capability: Continuous self-test with fault indication. HART® provides access to sensor health, calibration due, and event logs. The MPD IR sensor has a long life and requires minimal maintenance.
Calibration: Simple one-person calibration using magnetic wand. No need to open the enclosure. Interval depends on application, typically 6 months.
Compatibility & Integration
Fully compatible with Honeywell XNX series accessories. HART® over 4-20mA allows connection to PLC, DCS, or SCADA. Works with Modicon Quantum systems and other industrial controllers. The UL/CSA approval meets global safety standards.
