Checking mechanical operation

This procedure will verify the attached index rotates freely and without resistance.

1. Rotate the index drive dial 3 times clockwise.

2. If it turns easily, rotate the drive dial 3 times counterclockwise to remove counts or subcounts from the mechanical index.

If it does not turn easily:

a. Rotate the drive dial 3 times counterclockwise to remove subcounts from the mechanical index.

b. Unscrew the index/module assembly and repeat from step 4 of “Installing index onto module” on page 2.

Note: Subcounts added to the electronic index during this procedure will be cleared when the index reading is programmed into the

module.

3. Verify that the gasket material on the index cover is free of rips or tears.

4. If the gasket cover is ripped or torn, removed the damaged gasket from the index cover and replace with a new gasket.

Mounting the module-index assembly

Note: Be sure to have your module/index assembly, screwdriver, index cover and index cover gasket within easy reach before starting

this procedure.

1. For Rockwell 415 modules Only: Install the meter adapter to the meter using the two 6/32” screws supplied in the assembly.

Note: Make sure the gears on the adapter and meter are properly meshed.

2. Visually align module wriggler with meter wriggler or meter adapter (drive dog).

• If 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.

4. While holding the assembly against the meter, gently try to turn the drive wheel clockwise, then counterclockwise.

• If the drive wheel meets resistance in both directions, it is properly mated. Proceed to step 5.

• If it meets no resistance in either direction, and can rotate freely through an angle of 360 degrees and beyond, then make

sure the meter is completely free of old gasket material and forcefully press the module into the meter. Repeat this step

(step 4). If the unit still does not correctly engage with the meter, return it to Elster Integrated Solutions.

• For American Meter modules Only: If the American Meter module meets resistance in one direction then turns 360

degrees the other way before again meeting resistance, it is not properly mated. Repeat from step 1.

Caution:

It is very 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 could also cause meter damage. CORRECT

EXECUTION OF STEPS 1, 2 and 3 IS CRITICAL.

5. While holding the module firmly in place so as to not lose the wriggler alignment, place the index cover and index cover gasket

onto the module/ index assembly.
