2. Set the ERT module cover aside where it will not be damaged or fill with rain, dirt, or snow. You will use
the cover later in this installation procedure.
Caution Use only dial-type indexes from National, Actaris, Schlumberger, or Sprague meters with the
500G ERT module.
Indexes with bow-tie shaped wrigglers are not compatible with the 500G ERT module. You must use a
compatible index.
Note National (Lancaster) meter indexes are av ailabl e in differ ent m odels :
Indexes with legs Indexes with mounting holes
Some National meter indexes have index legs to mount the index on the meter or ERT module. Some
indexes have both legs and index mounting holes and some have just mounting holes. Mounting methods
are dependent on the index. Index types require different mounting screws to attach the index to the 500G
ERT module housing (see Installation Prerequisites on page 7
ERT module housing mounting posts (1). Indexes with mounting holes must be attached to the ERT
module housing's bracket mounting posts (2).
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 the replacement index
mounting screws (SCR-0037-001, see Installation Prerequisites on page 7). Place one screw into the
index's right-hand mounting screw hole.
Note National index mounting screws are thread-forming screws and may require more torque.

National (Lancaster) Meter Installation
4. Attach the screw to the ERT module 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 10 - 20 x 3/8-inch screw (SCR-0017-001, see
Installation Prerequisites 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 ERT module shaft slot. Verify positive engagement of the
index wriggler to the ERT module shaft. (The following illustrations show index to shaft placement with
positive engagement.)
Warning Verify the index drive slot engages with the 500G ERT module shaft. Failure to mate the ERT
module shaft with the index drive post (or slot) can cause binding and lead to poor registration or meter
failure.
8. Install and tighten the left index mounting screw (for indexes with either mounting screw slots or holes).
Tighten the right index mounting screw. Tighten each index mounting screw evenly.
Warning Slide indexes with mounting screw slots all the way to the right. Verify the ERT module shaft
is aligned with the index drive post. Hold the index tightly in place while you secure the index mounting
screws.
9. Slide the ERT module cover over the index and housing. Verify the cover is installed correctly. The ERT
module label should be clearly visible and easily read.

To program the ERT module assembly
1. Program the meter drive rate into the 500G ERT module using the endpoint programming device.
2. For all programming and Check Endpoint operations, hold the handheld programmer as close to vertical as
possible. For optimal results, keep the handheld programmer within 6 feet of the target ERT Module.
3. Verify you have the correct programming mode (Mobile/Handheld Mode).
4. Programming parameters are based on the configuration file loaded into the ERT module programming
device. During programming, the ERT module is set to the nearest 100 cubic feet; the last two digits (tens
and units) are programmed as zeros (0). After programming is complete, the ERT module assembly will
read to the nearest cubic foot.
Installing the 500G ERT Module Assembly on the Meter
After you program the ERT module, complete the installation by installing the ERT module on the meter.
To install the 500G ERT module on the meter
1. Align the black wriggler (1) so one of its four drive fins lines up with the meter's drive dog (2).
2. Carefully place the ERT module on the meter.
Warning Failure to correctly align the meter drive post and ERT module wriggler can cause binding and
lead to poor registration or meter failure. If there is a gap between the ERT module gasket and the meter,
it may be the wriggler of the ERT module is dead-headed against the meter drive dog as shown in the
following illustration.
Remove the 500G ERT module assembly and repeat the alignment procedure. You must engage the meter
drive dog in the ERT module wriggler.

3. Insert the right module mounting screw and tighten the screw until the gasket is against the meter. Do not
completely tighten the mounting screw.
Note Use the original mounting screws to mount the 500G ERT module if they were the correct size and
not corroded. If you discarded the original screws, use the correct replacement screws (see Installation
Prerequisites on page 7
.)
4. Slightly raise the left side of the ERT module (the module will rotate on the right screw) until the left ERT
module mounting hole is approximately 1/4-inch above the left meter mounting hole.
5. Rotate the ERT module down until the ERT module mounting hole is approximately 1/4-inch below the
meter index mounting hole.

6. Rotate the ERT module up to align the left mounting holes. Raising and lowering the ERT module on the
meter drive post facilitates the proper positioning and engagement of ERT module wriggler with the meter
drive post.
7. Insert the left mounting screw and tighten a few turns.
8. Tighten the right and left ERT module-to-meter mounting screws in an alternating pattern. Tighten each
mounting screw evenly.
Important Meter manufacturers: torque the mounting screws 15 to 20 inch-pounds.
Tip The following conditions ensure proper engagement of the ERT module to the meter:
• The ERT module fits flush against the meter body--there are no gaps between the ERT module gasket
and the meter body.
• The ERT module mounting holes align with the index cover mounting holes on the meter body.
• The meter test dial moves in relation to gas flowing through the meter.
9. Place a new tamper seal in the tamper seal cups surrounding the two mounting screws. Press the new
tamper seals into place using an 11/32-inch nut driver or similar blunt tool.
10. Complete any necessary paperwork and properly dispose excess installation materials and scrap from the
customer premises.
