User's Manual Part 2

Attaching the 100G Datalogging Gas Endpoint Assembly to the Itron/Actaris Meter
100G Datalogging Installation Guide - Direct Mount 51
If your index has legs with mounting screw slots, skip steps 3 and 4. If your index has
mounting screw holes in the index back plate (no legs), perform steps 3 and 4, and
skip steps 5 and 6.
3. For indexes with mounting screw holes in the index back plate (no legs), use
replacement index mounting screws (SCR-0037-001 - see Installation Prerequisites on
page 8). Place one screw into the index's right-hand mounting screw hole.
Note National/Lancaster index mounting screws are thread-forming screws and
may require more torque.
4. Attach the screw to the endpoint housing's right-index mounting post just enough to
hold the screw and the right end of the index in place.
5. For indexes with legs (mounting slots), screw one 6 - 19 x 3/16" screw (SCR-0015-
001 - see Installation Prerequisites on page 8 for screw information) into the right
index mounting post one or two turns. Do not completely tighten the screw.
6. Place the right index mounting screw slot under the screw head. Do not completely
tighten the screw.
7. Carefully slide the index drive post into the endpoint wriggler. Verify positive
engagement of the index wriggler to the endpoint drive dog. (The following photos
show three types of index/wrigglers with positive engagement.)
Caution Verify the index drive slot engages with the 100G Datalogging Gas
Endpoint wriggler. Failure to mate the endpoint wriggler with the index drive post
(or slot) can cause binding and lead to poor registration or meter failure.
