The wire is housed in a PVC jacket with UV inhibitors. A black-jacketed wire is supplied on single-port MTUs and for port 1 of dual-port MTUs. A grey jacket is used for the port two input to dual port MTUs. Wire Length – MTUs are provided with a standard wire length of 12 feet. Additional wire may be used if necessary. A maximum run of up to 500 feet can be used to position the MTU in a favorable location. Use like-colors for cable jackets and individual wires when extending MTU wiring. Some specific meters may impose other wire length limitations. Consult the meter manufacturer. Wire Routing - Wires should be attached to walls with 9/16” staples. If wire clearance holes are needed to route wire from the meter to the MTU, drill a ¼” hole using an appropriate drill bit. The installer is responsible for the selection of an appropriate location for any hole to be drilled. Note: Wiring must be in accordance with all national and local codes. Wire Protection - A drip loop below the MTU is not required. Inspect wire to ensure that routing and stapling have not caused wire damage. Pull the wire lightly at each staple to make sure that the staple is not set too tightly. Any splices made to wire must be suitable for the environment and made in accordance with national and local codes. Page 5
MTU Instructions General Installation and Wiring Guidelines They must be secure and made in accordance with the connection supplier’s instructions. Generally, gel-filled Insulation Displacement Connectors (IDCs) such as 3M ScotchLok or AMP Tel-Splice connectors should be used on all wire-to-wire connections. Splices located outdoors or in meter pits should be further protected through the use of a direct burial kit. This consists of a gel-filled plastic tube that houses the individual wire-to-wire splices to provide additional protection from the elements. MTU Positioning and Mounting General - MTUs must be positioned and mounted properly to ensure optimum RF signal propagation. Each MTU contains an internal antenna near the top front surface of the sealed enclosure. As a result, the MTU should always be mounted vertically and the STAR logo should face the installer. Since MTU transmissions are similar in nature to cellular phone signals, a cellular phone can be used to help to determine if a location is suitable for MTU mounting. If the cellular phone signal drops dramatically or indicates no signal at the desired location, it is possible that the MTU signal will also be blocked at this location. In this case, the MTU will have to be mounted in a different location, possibly on the outside of the structure. Keep the MTU away from all other electrical wires. Note: Do not mount the MTU under wiring such as Romex, AC power wires, cable TV wire, or telephone wire. Do not allow these wires to lay on top of, or in front of the MTU. Note: Keep the MTU six inches away from metal items such as pipes, conduit, electric meters, electrical boxes, and downspouts. Make sure screws used to mount the MTU do not protrude and pierce or otherwise damage any wires, cables, or pipes. Use of Spacer – There are two primary styles of MTUs. The Original Flatpak STAR MTU requires the use of a spacer (Hexagram Part Number 056-5155H1) when the MTU is mounted on any surface other than wood. The NEW Flatpak STAR MTU is a modified design that can be directly mounted to a variety of surfaces without the use of a spacer. See the examples below for additional information. Page 6
MTU Instructions General Installation and Wiring Guidelines NEW Flatpak STAR MTU – An example of the NEW Flatpak STAR MTU is shown below. These MTUs are approximately 6.5” x 4.25” x 1.5” thick, and can be mounted on most surfaces without the use of a spacer. Original Flatpak STAR MTU – An example of an Original Flatpak STAR MTU is shown below. These MTUs are 6.5” x 5.5” X 1” thick, and require a spacer if mounted on any material other than wood. Note: Do not use a spacer when mounting an Original Flatpak STAR MTU on wood. Page 7
MTU Instructions General Installation and Wiring Guidelines Outdoor Mounting MTUs mounted outdoors are typically mounted to the side of buildings, to a stationery post, to the piping surrounding the meter, or to a pit lid. Mounting to a Buiding or Post If the unit is being mounted to the outside of a building, the MTU will be connected to wires that lead from the inside to the outside of the building. If existing wire is used, it must be of the same quality as specified in MTU Wiring. It must also be in good condition, without breaks, damage, or corrosion. Step 1 – Select a mounting location for the MTU that will allow optimum signal transmission. Step 2 – Run wiring from the MTU to the meter. If a splice is required, it may be placed inside or outside. For special circumstances, contact your supervisor. If using existing wiring, remove any box that houses the outside wires. Step 3 – Mount the MTU on the side of the building. • The MTU must be mounted level, vertically with the STAR logo facing the installer. Allow a 1” space between the top of the MTU and the overhang of the siding above it. This is critical for proper radio signal transmission. • Use a Spacer (Hexagram Part Number 056-5155H1) if mounting an Original Flatpak STAR MTU on a non-wood surface. CAUTION! Do not over tighten screws. Excessive torque will crack the MTU enclosure. Do not tighten screws beyond the point that the MTU touches the mounting surface. Step 4 – Make the appropriate connections to the meter. Refer to the specific MTU Instruction for the meter in use. Bar or Pipe Mounting Particularly in outdoor gas applications, it is sometimes convemient to mount the MTU to the connecting piping. With the Original Flatpak STAR MTU this is easily done using a bar-mount spacer and two 18” long tie-wraps, (See Recommended Supplies.) Step 1 - Thread the tie-wraps into the bar mount spacer as shown here. Page 8
MTU Instructions General Installation and Wiring Guidelines Step 2 - Attach the spacer to the MTU using #10-32 stainless steel screws, nuts and washers. Tighten the screws to 12 to 15 in-lb. On a standard drill driver with 0 to 24 torque settings, this is typically the #10 setting. Step 3 - Wrap the tie wraps around the bar as needed, pulling the ties around (through the spacer plate) as they are tightened. Step 4 - Adjust the MTU as needed and pull the tie wraps tight. Step 5 - Trim off the excess tie wrap, leaving about a ½” tab. Step 6 – Once Installation is complete, program the MTU using the STAR Programmer Software and your MTU Programmer. Pit-Lid Mounting For water or gas meters located in meter pits, MTUs can be mounted to the lower surface of the pit lid if an approved, non-metallic pit lid is used. In these applications, the MTU is mounted with it’s front surface facing the bottom surface of the lid, as shown below Original Flatpak STAR MTU When NEW Flatpak STAR MTUs are mounted in this manner, spacers are used between the MTU mounting tabs and the lower surface of the pit lid, as shown below. Revised Flatpak STAR MTU Page 9
MTU Instructions General Installation and Wiring Guidelines A long spacer is available, for use when the lower surface of the pit lid is a flat, solid surface. A short spacer is used when the lower surface of the pit lid in use has a ribbed construction. Contact Hexagram for information on approved non-metallic pit-lids. Indoor Mounting For an inside mount, mount the MTU vertically on a ceiling joist. It is important to mount the MTU as high as possible. Note: The MTU must be mounted above grade. Because the outside wall of a building can have metal siding or foil insulation, keep the MTU a few inches away from the outside wall. Transmissions easily pass through wood and masonry. Do not install an MTU inside if the basement has a metal ceiling or foil-lined insulation in the ceiling or if it has foil on the sidewalls running from grade to ceiling. This will prevent the signal from transmitting effectively. Large metal objects such as heating ducts, steel cabinets or metal ceiling structures can block MTU transmissions. Select locations that are at least five to ten feet away from objects such as these. Do not mount the MTU if large metal objects, such as heating ducts, block both the front and rear of the MTU. If absolutely necessary, a single large metal object may be located several feet away from the MTU. Unfinished Basement Step 1 – Select a mounting location for the MTU that will allow optimum signal transmission. In unfinished basements, this is typically high on a ceiling joist, at least a few inches away from outside walls. Step 2 – Mount the MTU. • The MTU must be mounted level, vertically with the STAR logo facing the installer. Allow a 1” space between the top of the MTU and any overhang above it. This is critical for proper radio signal transmission. • Use a Spacer (Hexagram Part Number 056-5155H1) if mounting an Original Flatpak STAR MTU on a non-wood surface. CAUTION! Do not over tighten screws. Excessive torque will crack the MTU enclosure. Do not tighten screws beyond the point that the MTU touches the mounting surface. Page 10
MTU Instructions General Installation and Wiring Guidelines Step 3 – Run wiring from the MTU to the meter. Carefully staple the wire to the wall every 18” and at every change in direction using 9/16” staples. All turns are to be at right angles. If wire must be run on masonry, secure it with wire clips. Run wires parallel to the joist. If a joist must be crossed, run at a 90 degree angle. If the MTU input cable must be extended, use an appropriate splice. Make sure inner conductors are not nicked during stripping. Step 4 – Make the appropriate connections to the meter. Refer to the specific MTU Instruction for the meter in use. Finished Basement Step 1 – Select a mounting location for the MTU that will allow optimum signal transmission. In Finished basements, this may be high on a ceiling joist in an unfinished section of the basement or high on an interior wall near a window or outside wall, but at least a few inches away from outside walls. Note: Ceilings may contain metal. Therefore, the MTU should be placed 2 to 3 inches down from a plaster or ‘dropped’ ceiling. Step 2 – Mount the MTU. • The MTU must be mounted level, vertically with the STAR logo facing the installer. Allow a 1” space between the top of the MTU and any overhang above it. This is critical for proper radio signal transmission. • Use a Spacer (Hexagram Part Number 056-5155H1) if mounting an Original Flatpak STAR MTU on a non-wood surface. CAUTION! Do not over tighten screws. Excessive torque will crack the MTU enclosure. Do not tighten screws beyond the point that the MTU touches the mounting surface. Step 3 - Run wiring from the MTU to the meter. Run all wiring behind the wall if possible. Carefully staple the wire to the wall every 18” and at every change in direction using 9/16” staples. All turns are to be at right angles. If wire must be run on masonry, secure it with wire clips. Run wires parallel to the joist. If a joist must be crossed, run at a 90 degree angle. If the MTU input cable must be extended, use an appropriate splice. Make sure inner conductors are not nicked during stripping. Step 4 – Make the appropriate connections to the meter. Refer to the specific MTU Instruction for the meter in use. Page 11
MTU Instructions General Installation and Wiring Guidelines Do 9 Do check your cell phone for presence of a strong signal before entering a building or basement. Do install the MTU if the signal remains strong at the installation location. (Note: This is a guideline only. It does not guarantee that the MTU will be received by the DCU. However, if cell phone service is affected by the location, it is possible that the MTU transmission will also be blocked.) 9 Do select the best possible location for MTU installation that will allow optimum signal transmission. 9 Do select a location for MTU installation that is above grade. 9 Make sure that the MTU is located near an outside wall, but not on an outside wall. 9 Make sure the MTU in installed within 500 feet of the meter. 9 Do make sure that no staples have pierced the installation wire. 9 Do mount the MTU vertically and level with the STAR Logo facing the installer. 9 Do keep the MTU a few inches away from the outside wall in case of metal siding or foil insulation. 9 Do use a spacer when mounting an Original Flatpak STAR MTU on any surface other than plaster or wood. 9 Do use a spacer if you need to make a splice near the MTU and if the MTU is mounted outside. 9 Do keep the MTU at least 6” (the width of the MTU) from all pipes, conduit, electric meters, electrical boxes, downspouts, dumpsters, garbage cans, water, electric and gas meters, etc. 9 Do keep at least 4” between MTUs side to side and 3” top to bottom, when installing multiple MTUs. 9 Do mount an MTU 2” to 3” below a plaster ceiling or the metal grid of a drop ceiling. 9 Do use amp splices and 3M DBR Gel kits when making splices in pits. 9 Do make sure the correct meter type and size is selected. 9 Do make sure the MTU is programmed on. 9 Do program the MTU as the last step. Make sure it is mounted, wired, all splices are completed and tucked into place and wires are stapled in place. 9 Do follow all national and local codes when installing MTUs. 9 Do inspect all splices, connections and wiring for damage. 9 Do route all wires away from the MTU case. Page 12
MTU Instructions General Installation and Wiring Guidelines Don’t 9 Don’t make a connection or splice if any of the wires are nicked or cut. Re-strip the wire and start over. 9 Don’t install the MTU if the cell phone signal was strong outside the building or basement and then goes into “no service” or a very weak signal at the MTU installation site. 9 Don’t damage insulation with staples, or by rough handling. 9 Don’t stretch wire when installing. 9 Don’t exceed 500 feet total wire length between the MTU and the meter. 9 Don’t select a location for MTU installation that is easy to install, but will not allow for good signal transmission. 9 Don’t select a location for MTU installation that is below grade. 9 Don’t place the MTU under Romex, AC power wires, cable or TV wire, telephone wire, etc. Don’t allow these wires to lay on top of or in front of the MTU. 9 Don’t mount the MTU right next to conduit or metal pipes. 9 Don’t over tighten the screws when mounting the MTU. 9 Don’t route the MTU wire along the top or front of the MTU. 9 Don’t mount the MTU near 2 or more metal objects such as heating ducts. 9 Don’t mount the MTU behind metal objects such as washers, dryers, furnaces, hot water tanks, metal sinks, metal shelves, dumpsters, garbage cans, water, electric or gas meters, or any other large metal objects. 9 Don’t mount the MTU in a basement that has metal ceilings unless there is an opening in the ceiling that is above grade where the MTU can be installed. 9 Don’t mount the MTU near electrical wires. 9 Don’t stack MTUs on top of each other (back to front). 9 Don’t install an MTU if the case is cracked or broken. 9 Don’t mount the MTU in the center of a basement.

MTU Instruction for Rockwell/Equimeter/Sensus Gas Meters Tools Required To mount the MTU to these meters, you will need the following tools and equipment: • Cordless drill ⅜”, variable speed, with adjustable torque settings • #2 Phillips bit • Safety goggles • Phillips screwdriver • Slotted screwdriver Installation Procedure Before installing the MTU, anti-tamper, safety, and security hardware must be removed from the clear register cover. Step 1 - Remove the existing clear register cover by removing the four screws. Discard the screws and cover. Step 2 - Remove the register by removing the two screws. Set the register aside. Discard the screws. Step 3 - Insert the four 10-24 x 1⅛” screws through the holes on the MTU as shown. Step 4 – Turn the MTU over and insure that there is a pre-applied gasket on the back of the MTU as shown below. Note: Couplers are pre-assembled to the MTU. Insure that the couplers are firmly attached to the shaft and that the coupler on the front side of the MTU contains the magnet. Also, verify that the plastic washer is in place between the rear coupler and the MTU. Step 5 - Position the MTU on the meter. Rotate the coupler so that the gear tooth on the coupler engages with the gear teeth on the gas meter. Orientation is not critical, but you should be able to feel the teeth “bite” when you turn the coupler from the front of the MTU. Step 6 - Tighten the four 10-24 x 1-⅛” screws to 12 to 15 in-lb. On a standard drill driver with 0 to 24 torque settings, this is typically the #10 setting. Tighten corner to corner. Step 7 - Check the coupler. It should have slight play — it should not bind or turn too freely. Page 16
MTU Instruction for Rockwell/Equimeter/Sensus Gas Meters Step 8 – Select gear to fit between the register and the MTU without binding. Typically, the correct gear can be selected based upon the type of index in use, as shown in the following table. Type of Index Coupler Drive Gear Plastic, dial-type Blue Gear (Part # 056-5155G4) Brass, dial-type Red Gear (Part # 056-5155G3) Plastic, odometer-type Yellow Gear (Part # 056-5155G2) Place the selected gear into the coupling. The head of the pin on the gear needs to be facing out. CAUTION! Do not over tighten screws. Excessive torque may damage the MTU enclosure. Power tools are not recommended for use on steps 9-12. Step 9 - On the register, insert the screws and spacers. Note: Spacers may not be required with odometer-style registers. Step 10 - Mount the register to the MTU, fastening it to the mounting holes shown below. Hand tighten to a torque not to exceed 3-5 inch-pounds. Make sure the index register gear and the MTU coupler gear are engaged. Page 17
MTU Instruction for Rockwell/Equimeter/Sensus Gas Meters Step 11 - After you feel engagement between the index register gear and the MTU coupler gear, tighten the register screws until they are snug. Step 12 - Place the new cover over the register so that the top label or arrow is on top and the vent holes are on the bottom. Align the cover with the mounting holes on the MTU, press it into place, and insert the #10 x 1” screws. Hand tighten to a torque not to exceed 3-5 inch-pounds. The gasket should be compressed slightly. Step 13 - Replace any anti-tamper, safety, or security hardware onto the p-lastic cover as required. Step 14 – Once Installation is complete, program the MTU using the STAR Programmer Software and your MTU Programmer. Page 18

MTU Instruction for STAR Submetering MTUs with Pulse Adapters Tools Required • Crimping Pliers for Insulation Displacement Connectors (IDCs) • Wire cutters/stripper • Cleaner (non-residue type) and rag/paper towel • Stapler for ¼” wire and cable (Arrow T-25M) Introduction STAR Submetering MTUs with Pulse Adapters provide accurate, high-resolution data for point-of-use allocation billing for a wide variety of HVAC appliances. Note: Only on-off devices are suitable for application of these pulse adapter MTUs. • Voltage Sensing Pulse Adapters can be applied to gas appliances that are controlled by a standard 24VAC gas valve. • Temperature Sensing Pulse Adapters can be applied to gas water heaters, fireplaces and other HVAC appliances that do not have 24 VAC controls These units produce an extremely accurate pulse at a rate of 10 seconds per pulse (0.1 Hz or 6 pulses per minute) when the specified input conditions (voltage or temperature) are met. These pulses are counted by the MTU which periodically transmits the accumulated count to nearby Data Collector Units. Note: The submetering MTUs discussed in this instruction are for indoor use (dry locations) only. Connecting Voltage Sensing (Type P) Inputs Voltage Sensing (Type P) inputs are provided with a 2-wire connection that can be wired across (in parallel with) the 24 VAC gas valve solenoid of the furnace or other HVAC appliance. Simply connect the RED and BLACK wires across the gas valve solenoid. Once connected in this way, a voltage of between 18 and 30 VAC applied across the valve solenoid will cause the MTU to begin pulsing and recording usage. CAUTION Do not connect the white wire of the MTU when connecting voltage sensing inputs. Cut the white wire back to the cable jacket. Connecting the white wire may damage the MTU. Typical Furnace Application This procedure covers a typical installation of a voltage/current sensing pulse adapter on a gas furnace. Step 1 - Turn the furnace setting to "Pilot" so that it will not operate during the installation process. Step 2 - Mount the MTU on a wall, joist or other convenient location near the furnace to be monitored. Run the cable from the MTU to the gas valve solenoid of the device. Trim or extend the MTU cable, as needed. Care must be taken to protect the cable from damage by hot surfaces or sharp sheet metal. Use insulated staples or cable ties as needed. Note: Be sure to follow all General Mounting & Wiring Guidelines outlined in Publication 471-2000. Page 44
MTU Instruction for STAR Submetering MTUs with Pulse Adapters Step 3 – Connect the RED and BLACK leads from the MTU across (in parallel with) the 24 VAC control input to the gas valve. On most gas valves, these connections can be made at the terminals on the gas valve solenoid. ● The VIOLET lead is the positive side and must be connected to the RED wire of the MTU Input Cable. ● The RED lead of the thermocouple is the negative side and must be connected to the BLACK wire of the MTU input cable. Step 4 – Program the MTU using the MTU Programmer as outlined in the Programming section of this document. Typical Hot Water Heater Application Step 5 - Return the furnace setting to "Run". This procedure covers a typical installation of a temperature sensing pulse adapter on a gas hot water heater. Connecting Temperature Sensing (Type T) Inputs Step 1 - Turn the hot water heater setting to "Pilot" so that the heater will not operate during the installation process. Temperature Sensing (Type T) inputs are provided with a two wire connection designed to be directly connected to a Type E thermocouple that is supplied with the temperature sensing MTU. When the thermocouple reaches a temperature of 110◦ - 130◦ C (230◦ - 265◦ F), the MTU will begin pulsing and recording usage. Step 2 - Insert the copper thermocouple sleeve into the space under the draft-inducer cone at the top of the water heater. Position the tip of the thermocouple INTO the center of the flue as shown below. ( ½ to ¾ of an inch) By convention, Type E thermocouples are supplied with two color-coded leads. Page 45
MTU Instruction for STAR Submetering MTUs with Pulse Adapters Gently shape the copper sleeve on the thermocouple so that it does not contact the metal surface of the draft hood or the top of the hot water tank as shown in the side view illustration. Step 3 - Clean the surface area of the hot water heater under the thermocouple. Dry thoroughly. Locate and mount the two pressure sensitive hold-downs in the cleaned area. Locate one hold-down at the approximate center of the copper sleeve and the other at the very end so that they firmly anchor the thermocouple. Thread a cable tie through the slot in the hold-downs to fasten the thermocouple. If necessary, gently form the copper sleeve to facilitate mounting while insuring that the tip of the thermocouple is in the center of the flue and the copper sleeve is not in contact with metal surfaces. Step 4 - After the thermocouple sleeve is secure, route the thermocouple wire near the inlet or outlet water pipe. Use the third cable tie to secure the thermocouple wire to the pipe as a strain relief. Step 5 - Mount the MTU on a wall, joist or other convenient mounting location using two screws. Run the cable from the MTU to the end of the thermocouple wire. Trim excess MTU cable, as needed. Care must be taken to protect the cable from damage by hot surfaces or sharp sheet metal. Use insulated staples or cable ties as needed. Note: Be sure to follow all General Mounting & Wiring Guidelines outlined in Publication 471-2000. Step 6 - Splice the MTU wire to the thermocouple wire using the two IDCs provided. ● Connect the VIOLET thermocouple wire to the RED MTU wire. ● Connect the RED thermocouple wire to the BLACK MTU wire. Do not remove the insulation from either the MTU wires or the thermocouple wires; the IDC is designed to pierce the insulation. Step 7 – Program the MTU using the MTU Programmer as outlined in the Programming section of this document. Step 8 - Return the hot water heater setting to "Run". Typical Burner/Fireplace Application This procedure covers a typical installation of a temperature sensing pulse adapter on a burner or fireplace. Step 1 - Set burner or fireplace control so that the appliance does not come on during installation. Step 2 - Fasten thermocouple so that the tip is near, but not in, the flame when the gas is burning. Use metal clamps or wire fasteners to secure the thermocouple. (NOTE: Clamps or wire fasteners are not provided by Hexagram. Individual installation conditions will determine the type of fastener to be used.) A location must be selected that allows the thermocouple tip to reach at least 130° C (400° F). However, the tip temperature must not exceed 350° C (660° F).

MTU Instruction for Neptune and Schlumberger Water Meters Supplies and Tools Required See Publication 471-2000, General Installation and Wiring Guidelines for a complete list of recommended tools and supplies for MTU Installation. Installation Procedure Step 1 - Select a mounting location for the MTU that will allow optimum signal transmission, and install any needed wiring. Be sure to follow all General Installation and Wiring Guidelines as outlined in Publication 471-2000. Step 2 – Select the wiring diagram that applies to the meter you are connecting and make the appropriate wiring connections. a. Direct Wiring to Meter - MTU wiring is supplied stripped to a standard length that fits water meters with screw terminals. Simply wrap the wires around the screw terminal and tighten the screw. It is recommended that the screws be tightened to no more than 4 – 5 in-lbs. Over-tightening the screw can stress and possibly fracture the wire. b. Water Meter with Integral Cable - If the water meter is supplied with an integral cable and a cable-to-cable splice is necessary, use a gel-filled wire splice designed for outdoor (moisture applications) to seal the individual connections. Note: When connecting a dual port MTU to a compound meter, connect port 1 (black jacket) to the primary, or high-flow register and port 2 (grey jacket) to the secondary or low-flow register. Step 3 – Make a final visual check of the wiring from the MTU to the meter register. Verify that the cable routing is neat, secure and professional. Step 4 – Once installation and wiring are complete, program the MTU using the STAR Programmer Software and your MTU Programmer. NTG MTU The NTG MTU is a special purpose MTU designed specifically to support the advanced capabilities of Neptune’s E-Coder solid-state register. This MTU provides the following special functions when coupled to an E-Coder Plus register and properly programmed. • 8-Digit Readings – The NTG MTU reads and transmits the full 8-digit reading from the E-Coder at the programmed read interval, typically every 12 hours. A full range of read intervals are supported, including temporary read intervals for temporary monitoring purposes. Page 56
MTU Instruction for Neptune and Schlumberger Water Meters • Alarm Polling – The NTG MTU also automatically polls (reads) the E-Coder alarm indicators every 15 minutes. This happens automatically, independently of the standard read interval mentioned above. If the NTG MTU detects any change in the alarm status of the E-Coder Plus register, an alarm transmission is generated immediately, reporting the change in alarm status to the DCUs. Compatibility with Neptune E-Coder Registers Hexagram’s NTG MTU is compatible with Neptune E-Coder Plus solid state registers revision 05.98 or higher. Checking E-Coder Revision Level To check the revision level of an E-Coder register, use your hand to block all light from striking the E-Coder’s solar cell for approximately 20 seconds. Then, remove your hand allowing light to strike the solar cell. The E-Coder’s display will briefly flash all 8s, and then reveal a display like that shown below. The four digit number at the right of the display is the revision level. In the illustration above, the revision level shown is 05.98. Compatibility with Neptune ARB-V and ProRead Registers Upon initial installation, an NTG MTU can also be used with meters equipped with Neptune’s ARB-V or ProRead registers. These are standard absolute encoder registers without the advanced capabilities of the E-Coder register. When used with ARB-V or ProRead registers, the NTG MTU operates in standard mode, providing 6-digit readings and no specialized alarm polling. Note: Auto/ProRead registers must be programmed by the manufacturer for 3-wire mode. It is important to note that once an NTG MTU is programmed to function in the advanced mode with an E-Coder register, it can no longer be returned to standard operation. To caution the user, the display shown below will appear when first programming an NTG MTU for use with an E-Coder: CAUTION! Once an NTG MTU is programmed for use with an E-Coder it can no longer be used with other (non-E-Coder) registers. Page 57
MTU Instruction for Neptune and Schlumberger Water Meters Once the user selects Yes on the above screen and successfully completes programming the NTG MTU for use with an E-Coder Plus register, the NTG MTU can no longer be used with an ARB-V or ProRead register. From this point forward, only E-Coder meter types will be available for selection when programming this NTG MTU. Error Codes When an E-Coder meter type is selected while programming an NTG MTU with the MTU Programmer, the MTU attempts to communicate with the register using a special protocol that reads the status of the E-Coders leak, tamper and reverse flow detection indicators. If the MTU cannot successfully communicate with the register, an error code will be displayed on the MTU Programmer, as shown below. Pressing Enter in response to this display will display the current settings for the MTU, including the error code, as shown below. This error indicates one of the following problems: • Attempting to use an E-Coder meter type with a register that is not an E-Coder. • A defective E-Coder register. • Improper wiring between the NTG MTU and the E-Coder. (Refer to Publication 471-2110 for E-Coder wiring information.) Page 58

MTU Instruction for Rockwell/Equimeter Model 750-10000 Gas Meters Tools Required • Slotted (Flat-blade) screwdrivers in the following blade tip width sizes: 5/32” narrow-blade, 9/32”, and ½”. If desired, use torque driver, 10 foot-lb. range. • ½” combination (hand) wrench or socket/ratchet wrench. A torque wrench is recommended (30 inch-lb. range). • 8” adjustable wrench. • 5/16-18 blind-hole (bottoming) tap and mating size T-handle. • Canned compressed air. Also see Publication 471-2000, General Installation and Wiring Guidelines for a complete list of recommended tools and supplies for MTU Installation. Installation Procedure There are two parts to this procedure. First, the MTU must be wired to the IMAC Pulsimatic Transmitter (IPT). Once this is complete, you can then install the Pulsimatic Transmitter onto the Rockwell gas meter. Wiring the MTU to the Pulsimatic Step 1 – Unpack all of the components required to install the IPT. This should include the IPT itself, gasket and a hardware kit that includes (2 each) brass threaded rods, stainless flat-washers and hex nuts. Step 2 - When wiring to the IPT, support the IPT off of the work surface on the outside (topside) of its base so that pressure is not applied to the center drive shaft. Remove the cable clamp (screw) from inside the base. Step 3 – Trim the stripped ends of the MTU cable to ¼” or slightly shorter. When inserted into the terminal block, only a small amount of bare wire should be visible. Bare wire should not extend beyond the walls of the terminal block. This will present a shorting potential. Step 4 – Feed the MTU input cable through the sealtight strain relief in the base of the IPT. Loop the cable so that stripped ends of the wires can be easily inserted into the terminal block screws. The screws should already be open enough. Place cable clamp over the wire as shown. Step 5 – Insert the BLACK and WHITE wires into the COM terminal screw. Tighten the screw. Step 6 – Insert the RED wires into the NC BLU terminal screw. Tighten the screw. Page 68
MTU Instruction for Rockwell/Equimeter Model 750-10000 Gas Meters Step 7 – Pull most of the slack out of the cable (leave a slight amount of slack) and reattach cable clamp as shown below. DO NOT pull the cable taut. Step 8 – Tighten the nut on the sealtight strain relief. You will need to tighten the nut almost fully down (as shown) before it will bite on the MTU cable. Step 9 – Check that all wired terminal block screws are tight. Step 10 – Depending on the installation location, you may be able to mount the MTU at this time. During installation, the IPT body should be supported so as not to hang (apply tension) on the MTU cable. During the installation, do not allow the heavier body of the IPT to suddenly jerk the MTU cable as this could potentially damage the cable internally. Step 11 – Install the MTU into its intended location per the recommended procedure found in the standard Hexagram MTU installation manual. Installing the Pulsimatic Transmitter Step 1 – If necessary, remove tamper seals that cover the index cover screws. Loosen and remove screws securing the index cover. You may discard these screws as they will not be re-used. Remove the cover. If the cover has the tamper seal bosses, this cover will be need to be replaced. Step 2 – Loosen and remove the screws securing the index to the index plate. Save these screws as they will be re-used. Remove the index and set aside. Page 69
MTU Instruction for Rockwell/Equimeter Model 750-10000 Gas Meters Step 3 – If the index cover screws were difficult to remove, the threads in the index plate may need to be cleaned out before installing the hardware that retains the IPT. Use the blind-hole tap to carefully clean out/ clean up the threads of the (2) cover holes. Blow out the holes with compressed (canned) air. NOTE: It is not necessary to clean the index mounting-hole threads as these holes are not reused. Step 4 – Thread the (full thread) ends of the securing studs (2) into the index cover screw holes of the index plate. Lightly snug the studs by grasping them by the flat that is machined into the top of the stud. Apply the gasket over the studs as shown. Step 5 – Before setting the IPT over the mounting studs, you must align the shaft drive pin of the IPT so that it will engage inside the fork portion of the meter drive foot. Step 6 – Place the IPT (middle set of holes) over the mounting studs. Make sure that the IPT drive pin engages the fork of the meter drive foot. Step 7 – Mount the register onto the base of the IPT using the same screws that originally secured the register to the index plate (meter head). The drive foot of the index must engage the fork of the IPT drive shaft. Tighten/torque the screws to approximately 4-5 ft-lb. NOTE: If the index cover that was removed has the security cap boss extensions, this cover will need to be replaced with an index cover without the security cap bosses. Step 8 – Although not necessary, it may be desired to keep water or dirt from collecting in the unused corner mounting holes. If closing them is desired, use a permanent outdoor rated non-shrinking putty or caulk such as an RTV. Page 70
MTU Instruction for Rockwell/Equimeter Model 750-10000 Gas Meters Step 9 – Place the index cover onto the studs. It will fit over the index one way only. Apply a flat washer and nut onto each stud. Snug, and then tighten these nuts an additional ½ to ¾ turn maximum. The finished torque value is 25 – 30 inch-lb. Step 10 – Install Wire/Lead security seals if desired. Installation is complete.

When inserted into the terminal block, only a small amount of bare wire should be visible. Bare wire should not extend beyond the walls of the terminal block. This will present a shorting potential. Step 4 – Feed the MTU input cable through the sealtight strain relief in the base of the IPT. Loop the cable so that stripped ends of the wires can be easily inserted into the terminal block screws. The screws should already be open enough. Place cable clamp over the wire as shown. Step 5 – Insert the BLACK and WHITE wires into the COM terminal screw. Tighten the screw. Step 6 – Insert the RED wires into the NC BLU terminal screw. Tighten the screw. Page 74
MTU Instruction for American Model AL800-AL5000 Gas Meters Step 7 – Pull most of the slack out of the cable (leave a slight amount of slack) and reattach cable clamp as shown below. DO NOT pull the cable taut. Step 8 – Tighten the nut on the sealtight strain relief. You will need to tighten the nut almost fully down (as shown) before it will bite on the MTU cable. Step 9 – Check that all wired terminal block screws are tight. Step 10 – Depending on the installation location, you may be able to mount the MTU at this time. During installation, the IPT body should be supported so as not to hang (apply tension) on the MTU cable. During the installation, do not allow the heavier body of the IPT to suddenly jerk the MTU cable as this could potentially damage the cable internally. Step 11 – Install the MTU into its intended location per the recommended procedure found in the standard Hexagram MTU installation manual. Installing the Pulsimatic Transmitter Step 1 – If necessary, remove tamper seals from any of the 4 screws that secure the index plate. Loosen and remove the screws securing the index plate assembly. You may discard these screws as they will not be re-used. Remove the index plate assembly from the top of the meter. Do not disassemble the index cover from the index plate. Step 2 – If the index plate mounting screws were difficult to remove, the threads in the meter head (handhole plate) may need to be cleaned out before installing the hardware that will retain the IPT and index plate stack. Use the blind-hole tap to carefully clean out/ clean up the threads of the (2) cover holes. NOTE THAT THESE THREADS ARE #18-18. MAKE SURE TO USE THE PROPER TAP. Blow out the holes with compressed (canned) air. Page 75
MTU Instruction for American Model AL800-AL5000 Gas Meters Step 3 – Place the adapter plate contained in the installation parts onto the head of the meter with the ear holes aligned over the index plate mounting holes of the meter head. The embossed “AL800-AL5000” on the adapter plate is oriented to the front of the meter. Step 4 – AFTER PLACING THE APAPTOR PLATE, Thread the (18-18 thread) ends of the securing studs (4) into the index cover screw holes of the index plate. Lightly snug the studs by grasping them by the flat that is machined into the top of the stud. Step 5 - Apply the seal plate over the studs. Step 6 – Before setting the IPT over the mounting studs, you must align the shaft drive pin of the IPT so that it will engage inside the fork portion of the meter drive foot. Page 76
MTU Instruction for American Model AL800-AL5000 Gas Meters Step 7 – Place the IPT (4 corner holes) over the mounting studs. Make sure that the IPT drive pin engages the fork of the meter drive foot. Step 10 – Install Wire/Lead security seals if desired. Installation is complete. Step 8 – Before mounting the index plate assembly, the drive foot of the index must engage the fork of the IPT drive shaft. Mount the index plate assembly onto the base of the IPT over the same (4) corner studs. Step 9 – Complete the assembly by securing the index plate onto the studs, with the supplied (4) flat washers and nuts. Tighten these nuts a finished torque of 60 inch-lb. (5 ft-lb.). Page 77
