PRODUCT DESCRIPTION The Wall Meter Interface Unit1(Wall MIU1 or MIU1) by Schlumberger, is a compact electronic device that collects meter reading data from an encoder register and transmits the data for collection to a nearby line of sight CellNet MicroCell Controller(MCC) fixed network. This product is based on CellNet BAMM RF design. This is a one way transmission to MCC. Since the MIU can be mounted as much as 500 feet from the encoder register, (See Table 1.

SECTION 2 INSTALLATION This section describes storage and unpacking instructions, preliminary tests, tools and materials, site selection, and installation. STORAGE Inspect shipping containers for damage upon receipt and inspect contents of any damaged cartons prior to storage. Store the cartons in a clean, dry environment. The temperature should remain between -22° and 149°F (-30° and 65°C). Keep in mind that the Wall MIU1 has an internal battery.

Verifying/Preparing the Encoder Register This Wall MIU1 is designed for use with Schlumberger ProRead Encoder Rev. E, D and C. Before installing an MIU, the encoder register must be correctly wired and/or programmed to work with the MIU.

2-7 5 Thread the cable around the strain relief posts (Figure 2.6). Figure 2.6 Cable Threaded Around Strain Relief Posts 6 Use a generous amount of moisture protection compound (Dow Corning #4 ® or GE Novaguard GB24 ® ) to completely cover the terminal screws and exposed wire (Figure 2.7). Figure 2.7 Installing Moisture Protection Compound 9 15956 Rev.

7 Align the cable with the notch in the terminal screw cover and snap the cover onto the encoder register (Figure 2.8). Figure 2.8 Covering the Terminal Screws 8 Run the cable from the MIU installation point to the encoder register, fastening it securely as necessary. 9 If necessary, drill a hole in an appropriate location and run the cable through the hole to the outside of the building. 10 15956 Rev.

Installing the MIU Please read and comply with all of the information in “Verifying/Preparing the Encoder Register” before continuing with this section, “Installing the MIU.” Please read this entire section before attempting an MIU installation: 1 Select a location for the MIU that meets the recommendations in “Site Selection.” 2 Fastening the three-conductor cable securely as necessary, run it from where it exits the building to where the MIU will be mounted.

sure the cable stays in the notch during the installation of the Main Housing (Figures 2.11 and 2.12). 10 Install the Main Housing by mating the hinge elements at the top of the Main Housing to the hinge elements at the top of the Mounting Adapter and then lowering the Main Housing until is snaps into place. 11 Connect the appropriate color wire to each Terminal Screw (B = Black, G = Green, R = Red). 12 Follow the steps in “Testing the Installation.

4 On the three-conductor cable that is to be spliced on, strip off 3/4" of the jacket. Do not strip the insulation from the individual wires. 5 Match up one pair of colored wires (Black to Black, Green to Green, and Red to Red) and insert the matching-colored pair into a Scotchlok (Figure 2.13). Note: If the MIU will be connected to a Pro-Read ® encoder register, the Pro-Read ® must be programmed for three-wire mode using a Pro-Read ® programmer and its ten-digit TDI format.
PAGE 16
8 Repeat Steps 5 through 7 for each pair of wires. 9 Tuck the Scotchloks into the splice enclosure and route the cables through the cutouts at the ends of the splice enclosure (Figure 2.16). 10 Coat the inside of the splice enclosure with Dow Corning #4 ® or GE Novaguard GB24 ® moisture protection compound (Figure 2.17). 11 Close the splice enclosure, pressing it firmly until the teeth lock together (Figure 2.18). 16 15956 Rev.

REPLACING THE BATTERY Follow these steps to change-out a Wall MIU1’s internal Battery: 1 Unscrew the bolt holding the Main Housing to the Mounting Adapter. 2 Remove the seal wire or seal clip from the Seal Holes at the bottom of the Main Housing. 3 Punch the Tamper Pin out of the Terminal Screw Cover. 4 Remove the Terminal Screw Cover. 5 Remove the wires from the Terminal Screws. 6 Remove the seal wire or seal clip from the Seal Holes at the bottom of the Main Housing. 17 15956 Rev.
PAGE 18
7 Using a flat-head screwdriver, gently pry down the clip on the bottom of the Main Housing. When the clip clears the tab on the Mounting Adapter, pull the Main Housing away from the Mounting Adapter. 8 Remove the Main Housing by lifting it until it unhinges and comes free from the Mounting Adapter. 9 Remove the Battery from the Main Housing by pressing in on the left end of the Battery until it releases and comes free from the Main Housing.

Time between MIU transmissions - The time between MIU transmissions is set for approximately 15 minutes 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 Transmission Period and Randomness The random period generation uses the same CellNet ALOHA model to generate the transmit randomness.
PAGE 20
TESTING AND MAINTENANCE After the MIU has been installed and wired, follow these steps to verify that the MIU is working properly: 1 Activate the MIU by holding the magnet for two seconds against the arrow on the Main Housing. The arrow is just to the right of the Terminal Screws. 2 Use a CellNet installation tool to verify the transmission from the Wall MIU1. • Verify all electrical connections. • Test the installation again.
