DRAFTChapter 1 - CCU4 Collector Overview 1Chapter 1CCU4 Collector OverviewItron’s Cell Control Unit 4 (CCU4) collector is a self-contained device that collects energyconsumption and tamper data from Itron Encoder Receiver Transmitters (ERTs) installed oncommercial and residential utility meters, and then forwards this information over publicnetworks to a central data collection site (the fixed network headend). The collector’s modulardesign and ability to read water, electric and gas meter data with the same unit provides a scalablefixed network solution.The CCU4 collector is installed outdoors on utility poles and is powered by a 120 VAC powerline. If AC power fails, the collector continues to operate on battery power for up to four hours.The collector reads ERT Standard Consumption Messages (SCMs) and Interval Data Messages(IDMs) at preset intervals on the 910-920 MHz unlicensed band (ISM) using a radio frequency(RF) receiver. It then transmits the data at specified times of day to the headend through existingtelephone lines using a dial-up modem or through wireless transfer using a Cellular DigitalPacket Data (CDPD) modem and antenna. The collector also has a MAS band (952 MHz– 957MHz) transmitter to excite ERT modules programmed as wake-up devices.Once configured and installed, the CCU4 collector requires no onsite visits while functioningnormally. Changes to collection intervals or data transmission times, upgrades to software, andother functions are all configured remotely from the headend. For more information on theheadend, see the Fixed Network 2.0 System Reference Guide.Features• Transfers data to the central data collection site over public networks, instead of theproprietary Itron 1432 MHz network• Internet Protocol (IP) interface provides access using standard internet-based softwareapplications• Advanced digital radio technologies and full duplex radio increases the number ofreadable endpoints• Completely re-programmable from a remote location• Scalable from a single device covering a few endpoints, to thousands of devices coveringlarge metropolitan areas• Modular design allows adding different options to suit the installation and allowsincreased functionality in the future• Provides secure data transfer using standard encryption methods• Includes 10 Base-T Ethernet interface for configuration, diagnostics, and high speed datatransfer

DRAFTChapter 1 - CCU4 Collector Overview 3CCU4 Collector ComponentsCCU4 Collector ComponentsThe CCU4 collector’s modular design consists of a number of components fixed together to forma single weatherproof device. The rugged, adjustable mounting bracket secures the device in highwinds and under heavy ice loads. Electrical components are designed into a plastic enclosure thatprovides double insulation and a high level of safety while handling the device. All electricalconnections from the collector are fully isolated, meaning it does not require a connection to earthground.If data is transferred over a wireless cellular public network, the collector requires only a powerconnection. If data is transferred over a land-based public network, a telephone line or Ethernetconnection is also required.Figure 2: CCU4 Collector ComponentsCDPD AntennaUpper HousingCentral HousingLower HousingRF AntennaBattery CasePower ConnectorCommunicationsConnectorHanging PlateHanging Bracket
DRAFT4 CCU4 Collector Field Installation and Service GuideTDC-0359-000b 04/02CCU4 Collector ComponentsUpper HousingThe upper housing contains the public network interface modem and the external power andcommunications connectors. Each collector contains either a CDPD modem or a POTS (PlainOld Telephone Service) dial-up modem, but not both at the same time. The upper housing can bereplaced to change the method of public network access.CDPD ModemThe CDPD modem provides switched data communication services between the collector and theservice providers internet connection/frame relay. CDPD communication provides two-way,fully digital, 19.2 KBPS packet data networking services. Due to protocol overhead and security,the effective data rate for CDPD is between 9 KBPS and 14 KBPS, and will drop during periodsof interference and high network utilization. The antenna for the CDPD modem is integrated intothe top cover of the collector. CDPD service is offered by major cellular vendors in mostmetropolitan areas of North America.POTS ModemThe POTS modem is a dial-up modem operating at up to 56 KBPS. Electrical connection to themodem is through the same modem interface board as used by the CDPD modem. The modemis a transformer coupled device, which maintains the electrical isolation of the collector. Dial-upinternet service is offered by Internet Service Providers (ISPs) in most areas of North America.Communications ConnectorThe communications connector is a transformer coupled connection (maintaining electricalisolation) and is used on POTS versions of the collector to transmit data to the headend anddownload software through POTS lines. The same connector is used in the meter shop toestablish an Ethernet connection, using different pins, during initial configuration and softwaredownload.Power ConnectorThe collector input AC connector is a five position circular 3A/300V connector. Pins 2, 3 and 4are voided for high voltage line to line clearance. The five position circular connector is mountedon the collector housing, providing a watertight connection point for external power sources.Central HousingThe central housing is where the main processor, the compact flash memory, and the powersupply reside. The housing is well shielded to prevent interference with the sensitive radiosection.Beneath the processor section, in the lower portion of the central housing, are the radiotransmitter and receiver.
DRAFTChapter 1 - CCU4 Collector Overview 5CCU4 Collector ComponentsCompact Flash MemoryThe compact flash memory is a solid state hard drive that stores the complete operating systemand the collected data. It appears as a standard hard drive to the system. The compact flashmemory two copies of the operating system, so the entire network can be switched to a newoperating system at a scheduled time, but can still revert back to the earlier version if there is aproblem with the new operating system. If it becomes corrupted (virus/lightning strike/etc), theentire compact flash drive can be formatted and reloaded over the public network.Receiver and TransmitterThe receiver is a full duplex, enhanced version of the Itron G5 mobile radio receiver. A widebandreceiver identifies the presence and timing of an incoming ERT transmission, and a narrowbanddigital Fast Fourier Transform (FFT) based decoder locates and decodes the ERT message.The ERT wake-up transmitter is a modified version of the Itron G5 mobile transmitter. It operatesover the same MAS band (952 MHz – 957 MHz) but is optimized for a fixed network installation.Lower HousingThe lower housing protects the radio from the outside environment and is where the battery packand the 900 MHz diplexer and are located. The diplexer controls transmitting to ERTs on theMAS band and receiving from ERTs on the ISM band. The 900 MHz ERT antenna and groundplane attach to the bottom of the lower housing, pointing down.Battery PackThe battery pack is sealed in its own compartment within the lower housing and is vented to theoutside air for safety. The battery pack is a four-cell sealed lead acid battery pack (8.8V, 2.5 Amphours / 22 WHr). It is field replaceable and designed to last 5 years. An automatically resettingfuse protects the battery from shorts.If the AC power fails, the battery pack maintains system functions for 4 hours. To conservepower, the collector may reduce processor speed, turn off all unused peripherals, put the CDPDmodem into sleep mode (slowing web response time), and reduce the number of read cycles. Thislower performance mode also occurs during the 16-hour initial charge of the battery afterinstallation.The collector generates alarms at the headend when the battery fails or when low capacity valuesare detected.

DRAFT8 CCU4 Collector Field Installation and Service GuideTDC-0359-000b 04/02Installing a Davit on a Wood PoleInstalling a Davit on a Wood PoleThe CCU4 collector is installed on the davit of a pole, which is the part of the pole that extendsout, away from the pole and is parallel to the ground. A light pole has an existing davit that holdsthe light fixture, and the collector is installed about 6 in. behind the light fixture on the davit.Wood poles do not usually have davits, but you can install one on the pole with a davit kit. If thewood pole already has a davit attached, you do not need to add another unless installing thecollector on the davit exceeds the wind load rating of the davit, creates RF interference with otherequipment on or near the pole, or places the collector too near tree branches or otherenvironmental factors.If you are installing the CCU4 collector on a wood pole without an existing davit you can installa davit using the Itron CCU Upsweep Davit Kit or the Itron CCU Downsweep Davit Kit. Theupsweep and downsweep davit kits each contain a bracket with a davit and arm welded to it.The davit arm protrudes away from the bracket either up (upsweep kit) or down (downsweep kit).Choose between the upsweep or downsweep kit to provide the collector with clearance fromother equipment attached to the pole and from nearby tree branches or other environmentalfactors.The davit kit attaches to the wood pole with a long bolt that goes through the pole and a lag boltthat goes into the pole. The bolts and washers required to install the davit are not included in thekit, since the length of the longer bolt varies depending on the thickness of the pole.Required Tools and HardwareYou need the following tools and hardware to install the upsweep or downsweep davit kit on awood pole:• 1/2-inch diameter bolt long enough to insert completely through the wood pole• 1/2-inch diameter lag bolt• 1/2-inch diameter washer, lock washer, and nut• Drill with 1/2-inch diameter drill bit• Nut driver, wrench, or ratchet-wrenchTo Attach a Davit to a Wood Pole1. Place the support arm against the pole and mark the position of the top slotted hole.2. Drill a hole through the pole at the marked position.3. Insert a bolt through the pole so that it protrudes 1/2 inch out the other side.4. Insert the washer, lock washer, and nut onto the protruding tip of the through-bolt, andtighten the nut until the bracket is held in place.5. Slip the slotted hole of the bracket over the head of the through-bolt, and slide the bracketdown so that the head of the through-bolt is captured in the slot.6. Insert the lag bolt through the bottom hole of the bracket and into the pole.
DRAFTChapter 2 - Installation Considerations 9Calculating Wind Load7. Tighten the through-bolt and the lag bolt until the bracket is firmly attached to the pole andthe end of the support arm is parallel to the ground.Figure 3: Attaching a Davit to the Wood PoleCalculating Wind LoadWind load is the combination of maximum weight and Effective Projected Area (EPA) that thedavit or pole can withstand. EPA, the actual projected area of an object multiplied by itscoefficient of drag, is expressed as a decimal, such as 1.3. The manufacturer of the davit or poleshould provide wind load rating specifications.Before mounting a CCU4 collector onto the davit of a pole, you must calculate the wind load anddetermine whether the combined weight and the combined EPA of the collector and any lightfixture or other equipment already installed on the davit exceeds the limits for which theparticular davit and pole are rated.Follow the equations below to calculate wind load for each installation:(weight of light fixture, etc.) + (weight of CCU4 and mounting hardware) = total weight(EPA of light fixture, etc.) + (EPA of CCU4 and mounting hardware) = total EPAThe following example describes calculating the wind load for a light pole with one light fixtureand one CCU4 collector.Wood PoleUpsweep ArmLag BoltThrough-BoltDownsweep ArmDavit
DRAFT10 CCU4 Collector Field Installation and Service GuideTDC-0359-000b 04/02RF Antenna AngleExample: Aluminum Light Pole Wind LoadA G.E. Light Systems davit and pole support a maximum weight of 60 pounds and a maximumEPA of 1.5, rated at 100 MPHI (Miles Per Hour Isotach). The existing light fixture weighs 35pounds and has a .7 EPA. The CCU4 collector (including mounting hardware) weighs 23 poundsand has a .7 EPA. The combined weight of the collector and the light fixture is 58 pounds. Thecombined EPA of the collector and the light fixture is 1.4.The following equation shows the calculations for this installation:(35 lb) + (23 lb) = 58 lb(.7) + (.7) = 1.4Since the combined totals are less than the maximum weight (60 pounds) and the maximum EPA(1.5) ratings of the davit, the installation is feasible.RF Antenna AngleRegardless of the specific attachment point, the collector antenna must be vertical (plumb),extending downward, perpendicular to the horizon.Measuring the Mounting Angle of a Pole or DavitTwo factors involved in achieving a plumb installation are the angles of the pole and the davit.Using an Itron Protractor, you can measure the angles of the pole and davit, as described below.To measure the mounting angle of a davit, place the Itron Protractor on top of the davit abovewhere the collector will be mounted. Verify the angle is no more than 15 degrees away from 0degrees.To measure the slant of a wood pole, place the Itron Protractor against the wood pole. Verify theangle is no more than 15 degrees away from 90 degrees.Figure 4: Measuring the Mounting Angle of a Pole or DavitIf either angle is more than 15 degrees, adjust the angle of the collector when attaching it to thehanging plate by varying the connection points of the bolts connecting the hanging plate to thecollector’s L-brackets.75 90 7515 015DavitWoodPoleDavitWood PoleItron Protractor

DRAFTChapter 3 - Installing the CCU4 Collector 13Chapter 3Installing the CCU4 CollectorThis installation involves attaching the CCU4 collector to either the davit (the arm holding thelight fixture) of the light pole or to a davit that has been installed on a wood pole. In either case,a davit must already be available on which to install the collector. Once the collector is installed,you must supply it with power either from the photoelectric sensor of the street lamp or from thesecondary power wires of the wood pole.Required ToolsYou need the following tools to install the CCU4 collector on a davit:• 7/16-inch nut driver, wrench, or ratchet-wrench• Inch-pound torque wrench with 7/16-inch socket• Flathead screwdriver• Itron bubble-level to check the plumb of the collector• AC circuit tester or volt meter (if installing on a light pole)• Wire stripper and wire cable sleeve (if installing on a wood pole)Installation Procedure SummaryYou must perform the following procedures to install the CCU4 collector on a davit:1. Install the hanging plate.2. Attach the collector to the hanging plate.3. Attach the RF antenna.4. Connect the means of transmitting to the headend.5. Install the battery pack.6. Supply power to the collector.7. Verify the collector is operational.
DRAFT14 CCU4 Collector Field Installation and Service GuideTDC-0359-000b 04/02Installation Procedure SummaryInstalling the Hanging PlateThe hanging plate attaches to the light pole davit with two brackets that have sharp teeth on theside that contacts the davit, keeping the hanging plate firmly in place. When replacing thecollector with a new one, you can remove the old collector without removing the hanging plate,thus speeding the replacement and maintaining the general placement of the collector.To Install the Hanging Plate1. Using two of the 1/4-20 x 3-inch hex-head bolts, loosely bolt one end of each bracket ontothe hanging plate so that the brackets swing.2. With one hand, hold the hanging plate against the bottom of the davit at the place you areinstalling thecollector, and with the other hand, swing the unsecured ends of the bracketsover the davit.Note Install the hanging plate at least six inches from the light fixture to ensure the lightcover can open when the bulb is changed.3. While still holding the hanging plate in place, insert the two remaining bolts through theunsecured ends of the brackets and into the hanging plate.4. Tighten all four bolts with your fingers until the plate stays in place.5. Moving in a cross (X) pattern, torque all four bolts to between 50- and 60-inch pounds.Caution To achieve the clamping force needed to withstand 100 MPH winds, torque thefour hex-head bolts to the specification listed. If the bolts are under-torqued, the necessaryclamping force may not be achieved, and if they are over torqued, the brackets can becomeover-stressed, which may also reduce clamping force.Figure 5: Installing the Hanging Plate on the Light Pole Davit

To adjust the unit for plumb, place the bubble-level tool on a flat surface of thecollectorand, with one hand, tilt the unit until the bubble in the leveling tool is away from the wall.It is not necessary to center the bubble in the circle.Note If you do not have a bubble-level, adjust the unit so that the bottom is parallel withthe ground. This ensures the antenna is plumb (perpendicular to the ground, pointingdown) when you attach it in the next procedure.5. With the other hand, move in a cross (X) pattern and torque all four bolts to between 50-and 60-inch pounds.Caution To achieve the clamping force needed to withstand 100 MPH winds, torque thefour hex-head bolts to the specification listed. If the bolts are under-torqued, the necessaryclamping force may not be achieved, and if they are over torqued, the brackets can becomeover-stressed, which could also reduce clamping force.Attaching the RF AntennaBoth the POTS version and the CDPD version of the collector have an RF antenna that attachesto the collector bottom. The CDPD version has a second antenna that attaches to the collector top.You will install the CDPD antenna in the next procedure if you are installing that version of thecollector.Caution The two antennas differ in appearance and function. You can distinguish theCDPD antenna from the RF antenna by the two additional knobs on the base of the CDPDantenna.
