Installation Instructions

5 Attach the index to the module using the appropriate index screws. Do not over tighten the screws.
CHECKING MECHANICAL OPERATION
This procedure will make sure the attached index rotates freely and without resistance.
1 Rotate the index drive dial clockwise 3 times.
2 If the index drive dial turns easily, rotate the drive dial counterclockwise 3 times to remove the counts or subcounts from the
mechanical index. If it does not turn easily, unscrew the index/module assembly & repeat Step 4 in “Installing the index.”
3 Make sure that the gasket material on the index cover is free of rips or tears. If the gasket cover is ripped or torn, remove the
damaged gasket and replace it with a new gasket.
Subcounts added to the electronic index during this procedure will be cleared when the index reading is programmed into the
module.
MOUNTING THE MODULE/INDEX ASSEMBLY
Before mounting the assembly, be sure to have a screwdriver, index cover, and gasket within easy reach.
CAUTION
!
It is important that the wriggler on the module is correctly engaged onto the meter. If it is not, it could produce an erroneous
indication during utility leak test procedures that monitor drive dial (proving dial) movement. Incorrectly engaged wrigglers
can also cause meter damage. It is important that the following procedure is performed correctly.
1 For Rockwell 415 modules only: Install the meter adapter using the two 6/32-inch screws supplied in the assembly. Make sure
the gears on the adapter & meter are properly meshed.
2 Visually align the module wriggler with the meter wriggler or meter adapter (drive dog). If the wriggler cannot be put in a
fixed position, position it correctly by rotating the drive dial with your finger.
3 Mate the module wriggler with the meter wriggler or meter adapter (drive dog) and hold the mated assembly against the
meter.
