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

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

F0 Excessive negative drift or high IR

F1 Partial beam block or dirty lens

F2 Alignment

F3 Beam block

F5 Setup menu not exited

F6 Low supply voltage

F7 Heater error

F8 Failed zeroing

F9 Gas left (timeout)

F10 Reset short

F11 Unit overheating

tF7 Source 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

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
