CHAPTER 1 100T-CP Cathodic Protection Telemetry Module Overview A cathodic protection system protects buried ferrous metal pipelines from corrosion. Cathodic protection works by making a buried metal object slightly more cathodic (or negative electrically) when compared to the surrounding soil causing the metal object to give up electrons, not ions, to the soil. A loss of ions occurs when metal corrodes (rusts).

100T-CP Cathodic Protection Telemetry Module Overview Installation Prerequisites The following tools are required to install, program, and check the 100T-CP module. Specific tools may be required for some installation locations.
CHAPTER 2 Mounting the 100T-CP Module on the Test Station Post This chapter provides the instructions to mount the 100T-CP on the test station post (riser pipe).
Mounting the 100T-CP Module on the Test Station Post Mounting the 100T-CP Module on the Test Station Pipe The following items are required to mount the 100T-CP on the test station pipe: Itron Part Number Description TEL-1000-003 100T-CP cathodic protection telemetry module CFG-5006-701 100T-CP Hardware Installation Kit Kit includes: (1) one band clamp (2) two tamper seals pipe bracket adapter plate lightning suppressor kit (also includes 2 gelconnectors) Screws: (2) 1/2-inch, to attach the adapter pla
Mounting the 100T-CP Module on the Test Station Post 2. Remove the pipe bracket and band clamp from the hardware kit (Itron part number CFG-5006-701). 3. Loosen the band clamp screw until the end of the band releases. 4. Push the end of the clamp's band through the holes in the pipe bracket. Itron suggests orienting the pipe bracket as shown below. 5. Place the band clamp around the riser pipe approximately 3-1/2" below the test station base or approximately 2" below the previously drilled hole.
Mounting the 100T-CP Module on the Test Station Post 9. Insert the adapter plate mounting screws. Tighten the screws in an alternating pattern. 10. Route the 100T-CP cable through the channel in the standoff on the backplate. 11. Route the cable on the left of the mounting post slot.
Mounting the 100T-CP Module on the Test Station Post 12. Thread the 100T-CP cable through the hole previously drilled in the riser post and gently pull the cable through the top of the riser post. 13. Slide the 100T-CP module mounting post slot onto the mounting post on the adapter plate. Align the 100T-CP mounting screw holes with those on the adapter plate. Verify the cable is on the left side of the mounting post slot. 14. Insert the mounting screws and tighten in an alternating pattern.
Mounting the 100T-CP Module on the Test Station Post 15. Install the tamper seals in the screw mounting cups. A tamper seal is correctly seated when it is recessed 1/16" into the cup.
CHAPTER 3 Connecting the 100T-CP Module to the Test Station This section provides the instructions to connect the 100T-CP to the cathodic protection test station. Buried Reference Cell Installation The 100T-CP must be connected to a Cu-CuSO4 reference cell designed for burial to measure pipe to soil voltage. The reference cell must be purchased from a third-party vendor and installed according to the manufacturer's specifications.
Connecting the 100T-CP Module to the Test Station 3. Connect the 100T-CP lead wires to the lightning suppressor following the table indications. Lightning Suppressor to 100T-CP Connection Table Red lightning suppressor wire Red 100T-CP wire Black lightning suppressor wire Black 100T-CP wire Important Use an Itron-approved crimping tool to install gel connectors. Do not use a standard pliers. The crimping tool provides an even-pressured crimp to ensure a secure connection between the wires.
Connecting the 100T-CP Module to the Test Station 7. Perform a Check Endpoint using a handheld computer and FDM to display the pipe to soil and AC voltage readings measured by the 100T-CP. 8. A negative DC voltage indicates a successful connection. If the Check Endpoint indicates a positive DC voltage, switch the red and black lightning suppressor leads on the test station terminals. 9. Perform a Check Endpoint to verify a negative DC voltage.
