Solar Radiation Rejection

• The ULTIMA OPIR-5 has superior immunity to solar
  radiation and other external IR radiation sources.

6
Performance Certifications

• The ULTIMA OPIR-5 is the worlds first and only
  open path detector to meet agency performance
  requirements on both LELm and ppmm scales

7
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

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

11
Alignment

• Simple alignment process
• Arm or base mounts available
• Display
• Menus activated by magnet
• Enables easy alignment, setup diagnostics

12
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 500731999 Guide for the selection,
installation, use and maintenance of apparatus
for the detection and measurement of combustible
gases or oxygen.
13
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
14
HART

• The ULTIMA OPIR-5 is available with HART for
  better efficiency with remote communication
• Only the primary scale, LELm 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

15
HART Analog Signal for Faults

• Because HART requires a minimum current for
  operation, the ULTIMA OPIR-5s fault conditions
  use 3.5 mA as minimum analog output

Function Current Level (mA) Current Level (mA) Current Level (mA) Current Level (mA)
Function Analog Output (Standard) Modbus HART (Default) HART-modified Analog Output
Fault 0 0 3.5 1.25
Test Gas 1.5 1.5 3.5 1.5
Setup Mode 1.5 1.5 3.5 1.5
Beam Block 2.0 2.0 3.5 2.0
Startup 0 0 3.5 1.25
Zero Reading 4.04 4.04 4.04 4.04
Gas Concentration 4 20 4 20 4 20 4 20
Over-range 21.7 21.7 21.7 21.7
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
