Solar Radiation Rejection  The ULTIMA OPIR-5 has superior immunity to solar radiation and other external IR radiation sources.

Performance Certifications  The ULTIMA OPIR-5 is the world’s first and only open path detector to meet agency performance requirements on both LEL m and ppm m scales

Detector Placement  Open path detectors should be installed based on several considerations: –Hazard conditions within the installation area covered –Ventilation rates, direction, and presence of recirculation and dead zones –Sensitivity to low (geometric) sunlight, fog, and reflections –Powerful sources of electromagnetic emissions like high powered electrical towers –Structures that may interfere with line of sight * Health and Safety Executive, Offshore Division,” Fire and Explosion Strategy, Issue 1,” 2004.

Installation  When installing an ULTIMA OPIR-5 detector, it is useful to consider the following: –Vibration can create issues –Solid foundation improves alignment integrity –The longer the line of sight path, the more solid the foundation required –Maintain a 6” to 12” radius around the line of site beam to avoid reflective interference from piping and supports –For outdoor installations, consider maximum snow levels –Good immunity to fog, steam, and rain but immunity degrades over longer distances –Avoid pedestrian traffic or overhead cranes –Keep beam low and down wind for heavy gases like propane and high for light gases like methane

Split Concentration Range  With the split range function, users can monitor the entire span of gas concentration with a single analog signal –Reduces wiring and commissioning costs LEL m 5,000 ppm-m (0.1 LELm) AO (mA) Methane Gas Concentration (ppm-m) Methane Gas Concentration (LEL m)

Alignment  Simple alignment process –Arm or base mounts available  Display –Menus activated by magnet –Enables easy alignment, setup & diagnostics

Maintenance  As with other combustible sensors, the ULTIMA OPIR-5 should be included in the plant maintenance schedule* –Gas check frequency depends on operating conditions (ex. dusty, corrosive, or damp environment) –Before repair or maintenance, the gas detector should be removed to a safe place outside the area being protected  If the hazard is still potentially present, it will be necessary to use a replacement gas detector in the area until the original detector is reinstated * BS EN 50073:1999 “Guide for the selection, installation, use and maintenance of apparatus for the detection and measurement of combustible gases or oxygen.”

Diagnostics  The ULTIMA OPIR-5 has self-diagnostics that inform users when certain types of device failures have occurred Fault Code Description F0Excessive negative drift or high IR F1Partial beam block or dirty lens F2Alignment F3Beam block F5Setup menu not exited F6Low supply voltage F7Heater error F8Failed zeroing F9Gas left (timeout) F10Reset short F11Unit overheating tF7Source internal error

HART  The ULTIMA OPIR-5 is available with HART for better efficiency with remote communication –Only the primary scale, LEL m or split range, connects through HART  Benefits of the HART-equipped ULTIMA OPIR-5: –Better diagnostics –Improved management of maintenance history and event logging –Flexible and accurate digital transmission –Effective cost control of devices in the field –Installation savings due to fewer wires

HART –Analog Signal for Faults Because HART requires a minimum current for operation, the ULTIMA OPIR-5’s fault conditions use 3.5 mA as minimum analog output FunctionCurrent Level (mA) Analog Output (Standard) ModbusHART (Default) HART-modified Analog Output Fault Test Gas Setup Mode Beam Block Startup Zero Reading4.04 Gas Concentration4 – 20 Over-range21.7 On HART-equipped unit, user must select the HART-modified AO in order use AO values below 3.5 mA

AMS Device Manager  Asset management and process improvement –Check compliance to calibration schedule –Coordinate calibrations so as to reduce labor cost –Aggregate calibration to a control room –Track gas level remotely –Read fault conditions from control room; before sending technician to the field

Ultima OPIR-5 Summary  Ultima OPIR-5 Open Path IR Detector –Detects ppm Meter & LEL Meter –Path Length up to 150 M –Wide Temperature range –Global Approvals –Integral Display - Easy alignment, diagnostics and maintenance
