MSA Ultima OPIR-5 Alignment Manual

Alignment Guide—
Ultima® OPIR-5 Detector
Before Getting Started
Ensure that there is a clear, unobstructed path between the Source
and Receiver, and there is no significant amount of background gas
when the unit is setting the zero value, as this will alter the Ultima
OPIR-5's performance. Also, be sure to
between the Source and Receiver to determine the optimal
adjustment (AJ) value. It is recommended that two people are
involved in aligning the unit to speed up the process. One person

An alignment scope is helpful but not necessary, though it is
recommended for distances over 60m.

For both the and Receiver:
Source
• Check the four cap screws that hold the unit to the pan-tilt assembly and verify that the back two cap screws have been tightened
but the front two have not.
• On the pan-tilt assembly, verify that the front and back fine adjust screws are flush with the assembly surface, to allow full movement of tilt.
If necessary, use a 2.5 mm hex wrench to adjust the screws.
• Use the housing sights to aim the units at each other. Align the notch and pin of the sights with the center of the opposing unit.
• Verify that the Receiver does not display a fault code.
– To access the menu, place the magnet supplied with the Ultima OPIR-5 over the MSA logo on the label of the Receiver for approximately
five seconds. The display will cycle between the options:
rSt Reset—Resets relays
--- Test
SE Setup
in Flash Input Diagnostics
AJ Alignment/Adjustment—remove magnet to select
Fi Finish, return to normal operation
Remove the magnet when "AJ" appears to select Align/Adjustment.
• The Receiver will display "Axx" with an initial AJ "xx" value from 0 to 99 or "]-["if no Source signal is detected.
• The goal is to set the AJ value in accordance with the following table dependent on the distance between the Source and Receiver.
For example, if the Source and Receiver are 80 m apart the optimal AJ value would be between 35 and 43, with 43 being the optimal
number for a standard configuration unit; or 60-65 for an extended range unit, with 65 being the optimal number.

If this occurs, reapply the magnet and return to alignment mode.
