MSA Ultima OPIR-5 Alignment Manual page 2

You will now begin to align the system:
1. The front fine adjustment screw tilts the unit down. Starting with the Source, lightly tighten the front fine adjustment screw until it meets
some resistance. Slowly make a small turn to tighten the screw and lower the front of the unit. Wait a few seconds for the AJ number
to settle at the Receiver. Continue making small turns, waiting after each turn for the AJ number to settle. Once the AJ number begins
to decline, unscrew the front fine adjustment screw until it is flush with the assembly surface. Always be sure to back out screw
to avoid stripping.
2. Repeat the same procedure for the back fine adjustment screw on the unit. The back fine adjustment screw tilts the unit up. Lightly
tighten the back fine adjust screw until it meets some resistance, and then slowly make a small turn to further tighten it. Wait a few
seconds for the AJ number to settle on the Receiver. Continue until the AJ reaches its maximum and begins to decline. In most cases,
the AJ won't be in the optimal range listed in the table since the Receiver hasn't been adjusted yet. Unscrew the back fine adjustment
screw until it is flush with the assembly surface. Always be sure to back out screw to avoid stripping.
3. Secure the two front cap screws. Verify that the AJ number does not decrease by more than 2 (an increase of any amount is acceptable).
If it does decrease by more than 2, you will need to repeat steps 1 and 2.
4. Adjust the Source pan nut for maximum AJ by first loosening the pan nut, moving the unit left or right to optimize the AJ number.
Slowly tighten the nut at the bottom of the pan-tilt assembly while holding the left side of the Source. Verify that the AJ does not
decrease by more than 2 (an increase of any amount is acceptable). If it does decrease by more than 2, you will need to repeat steps 1 - 3.
• With the Source now secure, repeat steps 1-4 for the tilt and pan with the Receiver.
• Once the Receiver is secure, verify that the AJ is comparable to typical values listed
in the above table.
• At the Receiver, put the magnet on the MSA logo to exit alignment mode. The unit will
display a flashing "AC" and begin zeroing the gas reading. Once zeroing is complete,
the unit will display "0C", and then return to normal operation (0). System alignment
is now complete.
• If you're having difficulty aligning the unit within the AJ values listed in the table,
you can access the Flash Input Diagnostics mode via the menu, take note of the three
values supplied and call Tech Support for further assistance.
