Remove index cover. 2. Remove index from gas meter. 3. Mount AMR transmitter onto gas meter. 4. Assemble index and cover onto AMR transmitter. 5. Initialize AMR transmitter with HHT. Remove index cover 1. Use small flat screwdriver to punch out the seals that cover two (2) of the four (4) index cover screws. 2. Remove and properly dispose the four (4) screws holding the index cover onto meter, with flat screwdriver. If two (2) or more screws shear off during the cover removal (or were previously sheared off), the meter will need to be replaced by a qualified utility representative. Reinstall any index cover screws that were removed and cap with seals if possible. Enter the appropriate information in the Mint HHT and skip to the next work order. 3. Remove the index cover and dispose of properly. AMR Transmitter Mounting Instructions for Invensys (Equimeter, Rockwell) models R175, R200, R250, R275, R310, R315, R415 5 Remove index 1. Remove and properly dispose the two (2) screws holding the index onto the meter, with small flat screwdriver. 2. Remove the index and carefully clean any debris from it. Inspect for proper index operation by turning the input shaft and verifying that the gearing turns freely. Also, inspect the index for any missing or broken hands. Place the index, or a new index if necessary, on a clean surface near you for reinstallation later. 3. With a putty knife, scrap away any gasket material that remained on the meter when the index cover was removed. AMR Transmitter Mounting Instructions for Invensys (Equimeter, Rockwell) models R175, R200, R250, R275, R310, R315, R415 6 Mount Transmitter on meter Verify that the transmitter is functional: check that the magnet on the front cam is visible; with the HHT check the transmitter ID and validate with the transmitter label. Insure the four (4) mounting screws are available and within reach. Place the AMR Transmitter onto the gas meter. Adjust the Transmitter shaft’s position by holding it on the front side, and combine the Transmitter shaft gearwheel with the gas meter shaft gearwheel. 1. While holding the Transmitter in place, check that the shafts are correctly positioned by gently rotating the Transmitter’s shaft with your other hand. There should be just a slight freedom of motion. 2. Attach the Transmitter to the meter using the four (4) mounting screws with a Phillips screwdriver. Place all screws, then torque down two (2) diagonal screws. Check shaft motion transfer again, then tighten the last two (2) screws. 3. Should two (2) or more screws shear or strip during the installation, the meter will need to be replaced by a qualified utility representative. Remove the transmitter and reinstall the index and index cover on the meter with the original screws. Enter the appropriate information in the Mint HHT and skip to the next work order.

Insure the two (2) index screws are available and within reach. 2. Install the right side index screw to its place in the index and with the Phillips screwdriver and torque in just 2-3 turns, so that the index fits loosely on the Transmitter. 3. Align the index gearwheel drive with the Transmitter’s shaft; adjust the gearwheel’s position by holding the proving hand on the index front side, and insert into the cavity of the Transmitter’s shaft.

While holding the index in its position, insert the right screw further in, so that the gear wheels remain combined. Verify slight freedom of motion and then insert and tighten the left index screw. 5. While the index is still a bit loose, centralize its position. …

Theory of Operation General The device is a Direct Sequence Spread Spectrum burst transmitter for Automatic Meter Reading (AMR) of gas meters. This device is mechanically designed to fit on Sensus/Equimeter residential meters and is part of a family of products designed to cover the majority of meters, both residential and industrial, in use in the USA. The interface with the meter comprises a magnet mounted on a shaft extended from the meter and two reed switches mounted on the board of the unit. This battery operated device is maintained most of the time on stand-by and wakes up to accept and count pulses from the meter interface. Once every pre-programmed number of hours the device wakes up and generates air message containing information on the meter reading. The air message is a burst DS SPSP transmission in one of number of pre-defined channels. These messages are collected by network of base stations that covers the area of service. The base station decodes the upcoming messages and sends them via a backbone connection to a central computer, the Data Operation Center (DOC). Signal Description •Operation frequency band - 904.6 MHz (channel 5) to 925.4 MHz (channel 57). •Channel spacing - 0.4 MHz. •Modulation technique - DBPSK, Direct Sequence Spread Spectrum. •Chip rate - 1 Mchip/Sec. •Spreading sequence - 255 Maximal Length sequence. •Raw data rate –3921 Bit/Sec. •Preamble length –300 bits. •Raw data length –320 bits. •Error correction code –Convolution code, R=1/2, K=5. •Interleaver depth –20 bits. •Message duration –158mSec. Signal Generation The transmitter is a direct conversation burst transmitter. The transmitter comprises synthesized local oscillator, that works with 15 MHz crystal reference and generates carrier in the 902 - 928 MHz band with channel spacing of 0.4 MHz, printed modulator that receives carrier signal from the synthesized local oscillator and base- band signal from the signal spreading module and generates direct sequence spread spectrum signal, and power amplifier module that amplifies and feeds a printed antenna with 29dBm signal.
