CHAPTER 1 DRAFT Getting Started The 100G is Itron's latest gas encoder-receiver-transmitter (ERT®) module. ERT modules are radio-frequency (RF) devices that transmit meter data. The RF meter data can be received by a reading device that is within transmission distance of the ERT. Itron's 100G ERT module has increased output power over legacy gas ERT modules for increased RF transmission distance.

CHAPTER 2 DRAFT Installing the 100G Remote ERT Module The 100G Remote ERT Module can be mounted on a pipe, using the pipe bracket installation kit, or a flat surface. The 100G Remote ERT Module must always be mounted with the printed label right-side-up, and the encoder wires and tamper seals at the bottom, as shown. Top of ERT Cable comes out the bottom Tamper seals at the bottom Mount the Corrector Mount the corrector on the meter according to the Mercury installation manual.
DRAFT Chapter 2 Installing the 100G Remote ERT Module Pipe Mounting To mount the adapter plate on vertical a pipe 1. Get the pipe bracket from remote mount kit and a proper size band clamp. 2. Loosen the clamp screw until the end of the band is released. 3. Push the end of the band through this hole in the pipe bracket.
DRAFT Pipe Mounting 4. Place the band clamp around the pipe. 5. Push the end of the band through the hole in the band clamp and into the entrance to the screw assembly. Entrance to screw assembly Pass end of the band through this hole 6. Tighten the band clamp until the end of the band can be pushed into the hole in the pipe bracket.
DRAFT Chapter 2 Installing the 100G Remote ERT Module 7. Tighten the clamp screw three or four more turns to make sure the end of the band does not pop back out on this side of the pipe bracket. 8. Position the band clamp as shown then fully tighten the band clamp screw. 9. Place the adapter plate on the pipe bracket. The adapter-plate screw boss goes into this pipe-bracket recess.
DRAFT Pipe Mounting When the adapter plate is properly positioned on the pipe bracket, it looks like this. 10. Obtain two adapter-plate mounting screws (shown here actual size) from the installation kit. 11. Install the adapter plate mounting screws in these holes. Put screws in these holes 12. Tighten both screws to 9 to 12 inch-pounds of torque.
DRAFT Chapter 2 Installing the 100G Remote ERT Module Adapter Plate Mounting Positions The installation procedure in this section shows how to mount the adapter plate on vertical pipes. The following pictures show how to mounting the adapter plate on pipes that are either horizontal or at 45 degree angles. Regardless of which direction the pipe goes, the adapter plate mounting lug must always be at the top. If the pipe is at a 45 degrees angle up to the right, install the adapter plate as shown.
DRAFT Pipe Mounting Mounting lug Screws To mount the 100G Remote ERT Module on the adapter plate 1. Get the 100G Remote ERT Module and two 1-inch mounting screws from the installation kit. 2. Place the back of the ERT module against the face of the adapter plate.
DRAFT Chapter 2 Installing the 100G Remote ERT Module The adapter-plate mounting lug should be just above the ERT-module mounting lug recess. Mounting lug Mounting lug recess 3. Raise the ERT module until the adapter-plate mounting lug is as far as possible inside the ERT-module mounting lug recess.
DRAFT Pipe Mounting 4. Install the two ERT module mounting screws you got from the installation kit. When the ERT module is properly mounted on the adapter plate, it should look like this. 5. Tighten the screws to 9 to 12 inch-pounds of torque. Program the ERT The ERT must be programmed using the FC200SR with EndPoint-Link software. See the Endpoint-Link ERT Programming Guide (TDC-0411) for more information.
DRAFT Chapter 2 Installing the 100G Remote ERT Module To program the ERT module 1. Using the FC200SR, program the reading of the index that was on the meter into the ERT module assembly. • For initial programming, hold the FC200SR approximately 1 foot away from the 100G. • For reprogramming (30 days or more past initial programming), hold the FC200SR approximately 4 to 5 feet away from the 100G.
DRAFT Pipe Mounting 2. Strip one inch from the outer insulation and about 1/4-inch from the red,white and blue wires. Twist the blue and white wires together. 3. Install the Phoenix connector (supplied by Mercury). Connect the red, blue and white wires to the Phoenix connector terminals as directed in Code Settings on page 3. NOTE In EC-AT units, the connector might be soldered to the pulse board.
DRAFT Chapter 2 Installing the 100G Remote ERT Module 4. Install the connector so that the"K" terminal is topmost, leaving some slack in the cable. 5. To hold the cable in place, wrap and stretch some rubber tape at the compression connector.
DRAFT Pipe Mounting 6. Install and tighten compression nut. This provides strain relief and seals the connection. To install tamper seals and cable ties 1. Get two new tamper seals from the installation Kit. 2. Place anew tamper seal over each ERT module mounting screw.
DRAFT Chapter 2 Installing the 100G Remote ERT Module 3. Push both tamper seals all the way into place with a 1/4-inch nut driver or similar tool. The100G Remote ERT Module should look like this after the tamper seals have been installed.
DRAFT Pipe Mounting 4. Loop a cable tie around the pipe and the ERT cable. 5. Pull the cable tie tight and cut off excess length. Dispose of the cut-off piece properly. When finished, the cable tie should look like this.
DRAFT Chapter 2 Installing the 100G Remote ERT Module 6. Push any excess wire up between the back of the ERT module and the face of the adapter plate. Flat Surface Mounting To mount the 100G Remote ERT Module on a flat surface 1. Drill three pilot holes in the mounting surface the proper size for the mounting screws, as shown in the drilling template.
DRAFT Flat Surface Mounting The holes for the bottom two screws must be on a horizontal line. If you mount the ERT module on a wood surface, use the mounting screws included with the ERT module or screws with the same size heads. 2. Get the three 1 1/2 inch mounting screws from the installation kit. 3. Turn the top mounting screw part way into the mounting surface.
DRAFT Chapter 2 Installing the 100G Remote ERT Module 4. Get an ERT module assembly. 5. Turn the screw into the mounting surface until the back side of the ERT module mounting lug recess at the top of the ERT module will just barely slide under the screw head. 6. Push the ERT module upward until the screw head is all the way into the screw-head mounting recess at the top of the ERT module.
DRAFT Flat Surface Mounting 7. Install and fully tighten the two bottom ERT module mounting screws. Program the ERT The ERT must be programmed using the FC200SR with EndPoint-Link software. See the Endpoint-Link ERT Programming Guide (TDC-0411) for more information. IMPORTANT You must perform the following programming procedure for the ERT module to function properly. When programming the ERT module, you must take note of the drive rate shown on the index of the meter.
DRAFT Chapter 2 Installing the 100G Remote ERT Module 2. Read the ERT module assembly using the FC200SR. Consult the EndPoint-Link ERT Programming Guide (TDC-0411) or other applicable instructions for details on how to read an ERT. • If this reading is higher than the one you programmed in step 1 above, the ERT module assembly is counting correctly. • If the ERT module assembly reading is not higher than what was programmed in step 1, replace the ERT module with a new one.
DRAFT Flat Surface Mounting 3. Install the Phoenix connector (supplied by Mercury). Connect the red, blue and white wires to the Phoenix connector terminals as directed in Code Settings on page 3. NOTE In EC-AT units, the connector might be soldered to the pulse board. 4. Install the connector so that the"K" terminal is topmost, leaving some slack in the cable.
DRAFT Chapter 2 Installing the 100G Remote ERT Module 5. To hold the cable in place, wrap and stretch some rubber tape at the compression connector. 6. Install and tighten compression nut. This provides strain relief and seals the connection.
DRAFT Flat Surface Mounting To install tamper seals and cable ties 1. Get two new tamper seals from the installation kit. 2. Place a new tamper seal over each ERT module mounting screw and push both seals all the way into place with a 1/4-inch nut driver or similar tool. 3. Secure extra cable with a cable tie.
DRAFT Chapter 2 Installing the 100G Remote ERT Module 4. Pull the cable tie tight and cut off excess length. Dispose of the cut-off piece properly. When finished, the tamper seals and cable should look like this.
