R900 Wall and Pit MIU Installation and Maintenance Guide 1 1 Product DescriptionThis section provides a general description of the R900 Meter Interface Unit (sub-sequently referred to as R900 MIU or MIU).The R900 MIU by Neptune is a compact electronic device that collects meter read-ing data from an encoder register. It then transmits the data for collection by the meter reader. A walk-by handheld or mobile unit receives the data and stores it to be downloaded into the utility billing system for processing.The R900 MIU is easily installed and operates within an RF bandwidth which does not require an operating license. Because the R900 MIU can be mounted as far as 500 feet from the encoder register, optimum broadcast signal strength is obtain-able, ensuring a high percentage of accurate, one pass readings.The R900 MIU meets FCC regulations part 15.247, allowing higher output power and greater range. The R900 MIU uses frequency-hopping spread spectrum tech-nology to avoid RF interference and enhance security. The MIU reads the ProRead (ARB® VI) registers on an hourly basis and E-Coder (ARB VII) registers at 15 minute intervals and transmits the meter reading data and the unique 10-digit MIU ID every 14 seconds. This allows the meter to be read by a walk-by handheld or mobile data collection unit.The R900 MIU is designed to offer advantages to utility organizations of all sizes:• Increases meter reading accuracy.• Eliminates “hard to read” meters.• Protects utility liability by increasing meter reader safety.• Requires no programming. Figure 1 Wall MIU Figure 2 Pit MIUHowever, a ProRead (ARB VI) register must be programmed in a three-wire mode.
Product Description2 R900 Wall and Pit MIU Installation and Maintenance GuideProduct DescriptionR900 MIU ProgrammingThe MIU is NOT field programmable. At the factory, each of the following items are programmed into the MIU:• Serial numbers – Each MIU is given two unique serial numbers/identification numbers (two IDs for compound units). Even numbers are given to the single registers and odd numbers are given to a two-networked registers unit. Cus-tom serial numbers are not available. • Time between encoder register reads – The MIU reads the ProRead (ARB VI) register once an hour and E-Coder (ARB VII) registers at 15-minute intervals.• Time between MIU transmissions – The time between MIU transmissions is set for approximately 14 seconds for single registers, and alternates register trans-missions every eleven (11) seconds for two networked registers. Custom time is not available.RF Protocol Error Detection The RF protocol is comprised of a header, data packet, and an error detection mechanism that reduces the erroneous data. RF Frequency Control AlgorithmThe MIU’s frequency-hopping, spread-spectrum has a sequence of at least 50 differ-ent channels for transmitting data. Associated with the 50 channels are 50 frequen-cies that can be pre-selected in a pseudo random manner. These 50 frequencies are coded into the software. RF Transmission Period and RandomnessThe random period generation uses the same random seed created for the channel definition to generate the transmission randomness. The randomness algorithm is defined so that no two consecutive transmissions from two MIUs will interfere with one another.Low Battery RF EmissionsThe MIU stops RF transmissions when the battery discharges below the normal operating voltage. The R900 MIU avoids 914 MHz to prevent collision with the Advantage® probe.

See “Environmental Conditions” on page 4.Follow these guidelines when selecting a location to install the R900 MIU:• For best results, Neptune recommends selecting a location where there is no chance that another object can be set over the antenna.• Avoid installing the MIU behind metal fences or walls.• Make sure the pit location gives adequate room for installing both the MIU and the pit antenna.• For maximum performance, Neptune recommends that pit antennas be installed above the lid as illustrated in Figure 10.• When installing in a high-traffic area, Neptune recommends that the dome of the antenna be recessed in the pit lid as shown in Figure 11.• Recessing the installation reduces the range of the installation. Figure 10 Antenna Placement for Low Traffic Areas Some items may not apply to your specific installation or the list may not contain all required tools or materials.Always follow your company’s safety practices and installation guidelines when installing an MIU. Never perform an installation during a lightning storm or under excessively wet conditions. For maximum performance the flange of the pit antenna needs to be located above the pit lid.
Pit InstallationR900 Wall and Pit MIU Installation and Maintenance Guide 13 Figure 11 Antenna Placement for High Traffic Areas• For best results, Neptune recommends that the MIU be installed in a location that provides a direct line of site to the path of the meter reader.• Although the MIU has a cable already attached—either 6 feet or 25 feet long—some installations can require additional cable. In these cases, the maximum cable length between the encoder register and MIU depends on the register’s manufacturer and model. Refer to Table 4 for maximum cable lengths.Single Pit MIU InstallationThe following section describes how to install a single R900 MIU in a pit location.

Pit Installation20 R900 Wall and Pit MIU Installation and Maintenance GuideDual Register ApplicationsThe R900 can be connected to two networked ProRead (ARB VI) or E-Coder (ARB VII) encoder registers. The following section describes the configuration for a pit location. If you are installing one single R900 Pit MIU within a pit, complete the instructions contained in “Single Pit MIU Installation” on page 13. To connect two registers, complete the following steps. 1 Ensure the registers are programmed in network mode.2 Connect the registers by daisy-chaining the registers and MIU together using the 3-wire connector cable. See Figure 29. Figure 29 Compound Registers Wired to One MIU-• The field programmer must have software SESW 56.05 or higher.• ProRead (ARB VI) or E-Coder (ARB VII) registers cannot be pro-grammed while connected together in a network. Each register must be programmed separately prior to making the network con-nections.• For a compound register, the turbine side is considered the (Hi) side, and the disc side is considered the (Low) side. When connecting an R900 to two separate meters, select one meter to be the (Hi) side and the other to be the (Low) side.• Every R900 MIU has two ID numbers: one is listed as (Hi) side, and the other is listed as (Low) side on the bar-coded pull tabs. Be sure the appropriate tag is assigned to the correct register.

Pit InstallationR900 Wall and Pit MIU Installation and Maintenance Guide 21 Testing the InstallationTo test the installation, complete the following steps.1 Power up the handheld unit (HH with HHIU) and put in RF test mode. 2 When the MIU is installed correctly, its ID number(s) and meter reading(s) appear on the display of the HH. Verify the correct meter reading(s) by comparing it to the meter’s dial. If the readings are the same, proceed to the next section.3 If a meter reading does not appear on the HH’s display, or the meter reading in the HH’s display is not the same as the read-ing on the meter’s dial, do one of the following:• Reactivate the MIU using the magnet.• Verify all electrical connections.• Verify registers are programmed correctly.• Test the installation again.4 If a ProRead (ARB VI) Encoder Register is used:• Ensure the unit is programmed in 3-wire mode.• Verify all electrical connections.• Reactivate the MIU. (See Step 1.)5 If an ECRIII register is used, make sure the register is pro-grammed in a compatible format.If a problem still exists, contact your Neptune Sales Representative.To avoid RF signal saturation of the HH, do one of the following:• Position yourself at least two to three feet from the MIU. • Remove the antenna from the HH.Activating the MIU with a magnet is recommended, but not a mandatory step. The R900 automatically checks every eight (8) hours for the presence of a reg-ister. If one is detected, the MIU wakes up and starts transmitting.

Figure 37 Activating the MIUTesting the InstallationTo test the installation, complete the following steps.1 Power up the handheld unit (HH) test device and start the testing programs provided.2 When the MIU is installed correctly, its ID number(s) and a meter reading(s) appear on the display of the HH. Verify the correct meter reading(s) by comparing it to the meter’s dial. If the readings are the same, proceed to the next section.set screwEnd swipe here To avoid RF signal saturation of the HH, do one of the following:• Position yourself at least two to three feet from the MIU. • Remove the antenna from the HH.
Wall Installation28 R900 Wall and Pit MIU Installation and Maintenance Guide3 If a meter reading does not appear on the HH’s display, or the meter reading in the HH’s display is not the same as the read-ing on the meter’s dial:• Reactivate the MIU using the magnet.• Verify all electrical connections.• Test the installation again.4 If a ProRead (ARB VI) Encoder Register is used:• Ensure the unit is programmed in 3-wire mode.• Verify all electrical connections.• Reactivate the MIU. (See Step 1.)5 If ECRIII, make sure register is programmed in a compat-ible format.If a problem still exists, contact your Neptune Sales 6 To complete the installation, install a seal wire or seal clip through the seal holes at the bottom of the main housing. See Figure 38.7 Verify that the requirements of the site work order have been met and that you have recorded all information. 8 Clean up the installation site before leaving. Figure 38 Install Seal WireActivating the MIU with a magnet is not a mandatory step. The R900 automat-ically checks every eight (8) hours for the presence of a register. If one is de-tected, the MIU wakes up and starts transmitting.seal wire
R900 Wall and Pit MIU Installation and Maintenance Guide 29 6 Maintenance and TroubleshootingThis section takes you through maintenance and troubleshooting procedures for the R900 MIU. The first topic will guide you through the steps necessary to replace the battery that is in the main housing. In addition, this section will guide you through some troubleshooting procedures for both a six-wheel and a four-wheel encoder.Six-Wheel Encoder Normal OperationIf the odometer reads 123456, the display should show 1 2 3 4 5 5. Four-Wheel Encoder Normal OperationIf the odometer reads 123456, the display should show 1 2 3 4 0 0.Abnormal OperationBelow are examples of abnormal operation for four-wheel encoders. Abnormal operation for six-wheel encoders is similar except that digits occupy all six posi-tions.• If an (H) or a ( - ) occurs on any of the four positions, the display on the HH will display it. Examples: 1 2 - 4 0 0 or 1 2 H 4 0 0 • If the wire between the R900 wall MIU and the encoder is cut or reads as open, the display on the HH shows dashes. Example: - - - - - • If using ECRIII, verify data format is correct. • If using a non-AutoDetect ProRead (ARB VI) register, verify that it has been programmed correctly. All non-AutoDetect ProRead (ARB VI) registers must be programmed for 3W mode. • Use the magnet on the R900 MIU to force the R900 to read the encoder. • On the handheld, check the System Setup menu and verify the adapter type is set to R900.Hourly ReadsProRead (ARB VI) registers are read every hour and E-Coder (ARB VII) is read every 15 minutes.Note that the last digit displayed is a five if the last digit on the odometer is five through nine. The last digit displayed is a zero if the last digit on the odometer is zero through four.continued on next page
Maintenance and Troubleshooting30 R900 Wall and Pit MIU Installation and Maintenance GuideReplacing the MIU Battery (Wall and Pit)Follow these steps to change-out the pit R900 MIU’s internal bat-tery:Removing the Battery1 Slowly remove the pit lid.2 Remove the transmitter cover by removing the two Phillips head crews located inside the back cavity of the main housing. (See Figure 39.)3 Lift the transmitter cover from the MIU. Figure 39 Removing the MIU Transmitter Cover4 Remove the battery casing from the main housing by inserting a flat-head screwdriver and dislodging the battery from the battery compartment. (See Figure 40.) Figure 40 The Battery CompartmentBecause the MIU is connected to both the antenna in the pit lid and the meter in the pit base, take care not to strain the cable when removing the lid.transmitter coverscrewflat-headscrewdriverWhen removing the battery, it may be helpful to press on the connected end while prying the other end.
Maintenance and TroubleshootingR900 Wall and Pit MIU Installation and Maintenance Guide 31 Cutting and Splicing the Battery Wires1 As close to the battery casing as possible, cut the battery connection wires one at a time. See Figure 41.2 Insert battery wire left in MIU ensuring insulation has not been compromised. Figure 41 Cutting the Battery Connection 3 Use Scotchlok to splice the wires from the new battery casing to the wires that were connected to the old battery casing. See Figure 42. Figure 42 Splicing the New Battery4 Be sure to carefully position wires and Scotchloks into compartment in space available next to battery as shown in Figure 43, making sure the wires are not pinched when the battery is snapped into the MIU housing. Figure 43 Location of ToroidCutting the battery connection wires one at a time prevents shorting.Ensure the R900 MIU’s black wire is connected to the black wire on the new battery (-) and the red wire is connected to the red wire on the new battery (+).
Maintenance and Troubleshooting32 R900 Wall and Pit MIU Installation and Maintenance Guide5 Snap the battery casing into the receiving clips on the main housing. See Figure 44. Figure 44 Returning Spliced Battery to Main Housing6 Reactivate the MIU as shown in Figure 20 on page 16. For help with this procedure, refer to “Tying the Cable and Activiating the MIU” on page 16. Replacing the Transmitter Cover1 Secure the transmitter cover using the two Phillips head screws, until the cover is snug and fully seated.2 Replace the pit lid.3 Test the installation using the procedure in “Testing the Instal-lation” on page 21.Be careful not to pinch the battery wires between the cover and the housing.
