CCU4 Collector Overview

Itron’s Cell Control Unit 4 (CCU4) collector is a self-contained device that collects energy consumption and tamper data from Itron Encoder Receiver Transmitters (ERTs) installed on commercial and residential utility meters, and then forwards this information over public networks to a central data collection site (the fixed network headend). The collector’s modular design and ability to read water, electric and gas meter data with the same unit provides a scalable fixed network solution.
The CCU4 collector is installed outdoors on utility poles and is powered by a 120 VAC power line. 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 existing telephone lines using a dial-up modem or through wireless transfer using a Cellular Digital Packet Data (CDPD) modem and antenna. The collector also has a MAS band (952 MHz– 957 MHz) transmitter to excite ERT modules programmed as wake-up devices.
Once configured and installed, the CCU4 collector requires no onsite visits while functioning normally. Changes to collection intervals or data transmission times, upgrades to software, and other functions are all configured remotely from the headend. For more information on the headend, see the Fixed Network 2.0 System Reference Guide.

CCU4 Collector Components

CCU4 Collector Components
The CCU4 collector’s modular design consists of a number of components fixed together to form a single weatherproof device. The rugged, adjustable mounting bracket secures the device in high winds and under heavy ice loads. Electrical components are designed into a plastic enclosure that provides double insulation and a high level of safety while handling the device. All electrical connections from the collector are fully isolated, meaning it does not require a connection to earth ground.
If data is transferred over a wireless cellular public network, the collector requires only a power connection. If data is transferred over a land-based public network, a telephone line or Ethernet connection is also required.

CCU4 Collector Components

Upper Housing

The upper housing contains the public network interface modem and the external power and communications connectors. Each collector contains either a CDPD modem or a POTS (Plain Old Telephone Service) dial-up modem, but not both at the same time. The upper housing can be replaced to change the method of public network access.
CDPD Modem
The CDPD modem provides switched data communication services between the collector and the service 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 periods of interference and high network utilization. The antenna for the CDPD modem is integrated into the top cover of the collector. CDPD service is offered by major cellular vendors in most metropolitan areas of North America.
POTS Modem
The POTS modem is a dial-up modem operating at up to 56 KBPS. Electrical connection to the modem is through the same modem interface board as used by the CDPD modem. The modem is a transformer coupled device, which maintains the electrical isolation of the collector. Dial-up internet service is offered by Internet Service Providers (ISPs) in most areas of North America.
Communications Connector
The communications connector is a transformer coupled connection (maintaining electrical isolation) and is used on POTS versions of the collector to transmit data to the headend and download software through POTS lines. The same connector is used in the meter shop to establish an Ethernet connection, using different pins, during initial configuration and software download.
Power Connector
The collector input AC connector is a five position circular 3A/300V connector. Pins 2, 3 and 4 are voided for high voltage line to line clearance. The five position circular connector is mounted on the collector housing, providing a watertight connection point for external power sources.

Central Housing

The central housing is where the main processor, the compact flash memory, and the power supply reside. The housing is well shielded to prevent interference with the sensitive radio section.
Beneath the processor section, in the lower portion of the central housing, are the radio transmitter and receiver.

CCU4 Collector Components
Compact Flash Memory
The compact flash memory is a solid state hard drive that stores the complete operating system and the collected data. It appears as a standard hard drive to the system. The compact flash memory two copies of the operating system, so the entire network can be switched to a new operating system at a scheduled time, but can still revert back to the earlier version if there is a problem with the new operating system. If it becomes corrupted (virus/lightning strike/etc), the entire compact flash drive can be formatted and reloaded over the public network.
Receiver and Transmitter
The receiver is a full duplex, enhanced version of the Itron G5 mobile radio receiver. A wideband receiver identifies the presence and timing of an incoming ERT transmission, and a narrowband digital 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 operates over the same MAS band (952 MHz – 957 MHz) but is optimized for a fixed network installation.

Lower Housing

The lower housing protects the radio from the outside environment and is where the battery pack and the 900 MHz diplexer and are located. The diplexer controls transmitting to ERTs on the MAS band and receiving from ERTs on the ISM band. The 900 MHz ERT antenna and ground plane attach to the bottom of the lower housing, pointing down.
Battery Pack
The battery pack is sealed in its own compartment within the lower housing and is vented to the outside air for safety. The battery pack is a four-cell sealed lead acid battery pack (8.8V, 2.5 Amp hours / 22 WHr). It is field replaceable and designed to last 5 years. An automatically resetting fuse protects the battery from shorts.
If the AC power fails, the battery pack maintains system functions for 4 hours. To conserve
power, the collector may reduce processor speed, turn off all unused peripherals, put the CDPD modem into sleep mode (slowing web response time), and reduce the number of read cycles. This lower performance mode also occurs during the 16-hour initial charge of the battery after installation.
The collector generates alarms at the headend when the battery fails or when low capacity values are detected.

•41Series
•45Series
•50W
SSD (Solid State Demand ERT)
SCM and IDM messages- IDM first priority

Collector to ERT Ratio and Distance

Although the CCU4 collector potentially can read many more ERTs, to ensure all data is collected, place one collector for every 100 unique ERTs.
The collector reads ERTs within a maximum radius of 800 ft, although some environmental, weather, and terrain conditions can affect this distance.

Radio Frequency

To ensure RF signals are received, install the collector at elevations and locations where the greatest number of endpoints are in direct line of sight of the collector.
Avoid installing collectors in following ways:
Adjacent to or between tall buildings, signs, towers, or bridges
Within 500 ft of high power RF transmitters (such as paging transmitters, cellular
Near potential broadband sources of radiated RF energy (such as power line transformers
Near swaying limbs, branches, or cables that could strike the collector

Installing a Davit on a Wood Pole

Installing a Davit on a Wood Pole
The CCU4 collector is installed on the davit of a pole, which is the part of the pole that extends out, away from the pole and is parallel to the ground. A light pole has an existing davit that holds the 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 the wood pole already has a davit attached, you do not need to add another unless installing the collector on the davit exceeds the wind load rating of the davit, creates RF interference with other equipment on or near the pole, or places the collector too near tree branches or other environmental factors.
If you are installing the CCU4 collector on a wood pole without an existing davit you can install a davit using the Itron CCU Upsweep Davit Kit or the Itron CCU Downsweep Davit Kit. The upsweep 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 from other equipment attached to the pole and from nearby tree branches or other environmental factors.
The davit kit attaches to the wood pole with a long bolt that goes through the pole and a lag bolt that goes into the pole. The bolts and washers required to install the davit are not included in the kit, since the length of the longer bolt varies depending on the thickness of the pole.

Required Tools and Hardware

You need the following tools and hardware to install the upsweep or downsweep davit kit on a wood 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-wrench
To Attach a Davit to a Wood Pole
1. 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, and tighten 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 bracket down 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.

Calculating Wind Load
Wind load is the combination of maximum weight and Effective Projected Area (EPA) that the davit or pole can withstand. EPA, the actual projected area of an object multiplied by its coefficient of drag, is expressed as a decimal, such as 1.3. The manufacturer of the davit or pole should provide wind load rating specifications.
Before mounting a CCU4 collector onto the davit of a pole, you must calculate the wind load and determine whether the combined weight and the combined EPA of the collector and any light fixture or other equipment already installed on the davit exceeds the limits for which the particular 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 EPA
The following example describes calculating the wind load for a light pole with one light fixture and one CCU4 collector.
DRAFT
Chapter 2 - Installation Considerations 9

RF Antenna Angle

Example: Aluminum Light Pole Wind Load

A G.E. Light Systems davit and pole support a maximum weight of 60 pounds and a maximum EPA of 1.5, rated at 100 MPHI (Miles Per Hour Isotach). The existing light fixture weighs 35 pounds and has a .7 EPA. The CCU4 collector (including mounting hardware) weighs 23 pounds
and has a .7 EPA. The combined weight of the collector and the light fixture is 58 pounds. The
combined 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) = 1.4
Since 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 Angle
Regardless 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 Davit

Two 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 above where the collector will be mounted. Verify the angle is no more than 15 degrees away from 0 degrees.
To measure the slant of a wood pole, place the Itron Protractor against the wood pole. Verify the angle is no more than 15 degrees away from 90 degrees.
Figure 4: Measuring the Mounting Angle of a Pole or Davit
Itron Protractor
Wood

If either angle is more than 15 degrees, adjust the angle of the collector when attaching it to the hanging plate by varying the connection points of the bolts connecting the hanging plate to the collector’s L-brackets.

Grounding

The CCU4 collector does not require an earth ground connection because the unit is sealed and encased in plastic.

Unpacking the CCU4 Collector

Remove the CCU4 collector from its shipping container and verify the protective foam pieces are not severely damaged. If these pieces are damaged, and the collector has significant visible damage, it may not function correctly.
Important The collector must remain protected at all times prior to installation. After
unpacking the collector to configure it prior to installation, save the packing container and packing materials to use again when transporting the unit to its location in the field. After installing the collector, save the container and materials for transport in the event the collector malfunctions and must be shipped to Itron for repair.

DRAFT
Chapter 3 - Installing the CCU4 Collector 13
Installation Procedure Summary

Installing the Hanging Plate

The hanging plate attaches to the light pole davit with two brackets that have sharp teeth on the side that contacts the davit, keeping the hanging plate firmly in place. When replacing the collector 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 Plate
1. Using two of the 1/4-20 x 3-inch hex-head bolts, loosely bolt one end of each bracket onto the 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 are installing the over the davit.
Note Install the hanging plate at least six inches from the light fixture to ensure the light
cover can open when the bulb is changed.
3. While still holding the hanging plate in place, insert the two remaining bolts through the unsecured 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 the
four hex-head bolts to the specification listed. If the bolts are under-torqued, the necessary clamping force may not be achieved, and if they are over torqued, the brackets can become over-stressed, which may also reduce clamping force.

Installation Procedure Summary

Attaching the Collector to the Hanging Plate

The collector attaches to the hanging plate with four bolts inserted through the slots in the plate and into holes in four L-brackets on the collector. You can adjust the collector so the RF antenna is plumb by sliding the bolts up and down in the slots and tightening the bolts when the antenna is perpendicular to the horizon.
To Attach the Collector to the Hanging Plate
1. With one hand, hold the the unit with the slots on the hanging plate.
2. Insert each of the four 1/4-20 x 3/4-inch hex-head bolts through a slot and into an L-bracket hole.
3. Tighten the bolts just enough that the unit hangs from the plate but is still loose enough that you can slide it up and down in the slots.

4. To adjust the unit for plumb, place the bubble-level tool on a flat surface of the
collector and, 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.
Bubble away from wall
Note If you do not have a bubble-level, adjust the unit so that the bottom is parallel with
the ground. This ensures the antenna is plumb (perpendicular to the ground, pointing down) 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 50­and 60-inch pounds.
Caution To achieve the clamping force needed to withstand 100 MPH winds, torque the
four hex-head bolts to the specification listed. If the bolts are under-torqued, the necessary clamping force may not be achieved, and if they are over torqued, the brackets can become over-stressed, which could also reduce clamping force.

Attaching the RF Antenna

Both the POTS version and the CDPD version of the collector have an RF antenna that attaches to 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 the collector.
Caution The two antennas differ in appearance and function. You can distinguish the
CDPD antenna from the RF antenna by the two additional knobs on the base of the CDPD antenna. Installing an antenna in the wrong place may damage the collector and will cause it to fail to work as intended.
To Attach the RF Antenna
1. Align the RF antenna with the N-connector on the bottom of the unit.

Supplying Power to the Collector

Once the collector is installed on the davit, you must supply it with power either from the photoelectric sensor of the street lamp or from the secondary power wires of the wood pole.
Connecting the Collector to the Photoelectric Sensor
To power the collector when installing it on a light pole, you must remove the photoelectric sensor, insert the power adapter end of the power cable into the socket, and replace the photoelectric sensor.
To Connect the Collector to the Photoelectric Sensor
1. Verify power is available by using a voltmeter or AC circuit tester on the street lamp.
Note Before removing the photoelectric sensor, note the current orientation of the sensor
window. You must restore the sensor window to the same orientation (usually north) when finished.
If you do not have a voltmeter or AC circuit tester, verify power by placing your hand over the photoelectric sensor window.

4. To adjust the unit for plumb, place the bubble-level tool on a flat surface of the
collector and, 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.
Bubble away from wall
Note If you do not have a bubble-level, adjust the unit so that the bottom is parallel with
the ground. This ensures the antenna is plumb (perpendicular to the ground, pointing down) 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 50­and 60-inch pounds.
Caution To achieve the clamping force needed to withstand 100 MPH winds, torque the
four hex-head bolts to the specification listed. If the bolts are under-torqued, the necessary clamping force may not be achieved, and if they are over torqued, the brackets can become over-stressed, which could also reduce clamping force.
Attaching the RF Antenna to the New Collector
Both the POTS version and the CDPD version of the collector have an RF antenna that attaches to 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 the collector.
Caution The two antennas differ in appearance and function. You can distinguish the
CDPD antenna from the RF antenna by the two additional knobs on the base of the CDPD antenna. Installing an antenna in the wrong place may damage the collector and will cause it to fail to work as intended.
To Attach the RF Antenna to the New Collector
1. Align the RF antenna with the N-connector on the bottom of the unit.
2. Press the antenna onto the connector and turn the antenna clockwise until it no longer turns andisfirmlyinplace.

Reconnecting the Means of Transmitting to the Headend
If you are installing the CDPD modem version (part # CCU-4011-001), you must attach the CDPD antenna. If you are installing the POTS modem version (part # CCU-4012-001), you must reconnect the POTS cable.
To Attach the CDPD Antenna to the New Collector
1. Insert the antenna through the hole in the top of the hanging plate and align it with the N­connector on top of the unit.
2. Press the antenna onto the connector, and turn the antenna clockwise until it no longer turns and is firmly in place.

Installing the Battery Pack in the New Collector
The battery pack ships uninstalled in the same container as the collector. If the collector was configured at the depot, the battery pack may be stored in the battery compartment for transport.
Caution Do not connect the battery pack to the collector until the collector is in place on
the pole. If you connect the battery pack prior to installation, the collector may record erroneous data and the battery pack may completely lose power.
To Install the Battery Pack in the New Collector
1. Using a flathead screwdriver, loosen the four captive-screws holding the battery case in place.
2. Pull out the battery case.

Verifying the New Collector is Operational
Once the collector is installed and receiving power, it should appear onscreen at the headend. To verify the collector is receiving power and the software is operating correctly, you must call the headend and give the administrator the IP address and the number of the collector. If the administrator identifies the collector onscreen, the installation is complete.
To Verify the New Collector is Operational
1. Call the headend.
2. Give the administrator the ID number of the collector and its IP address.
3. Wait for the administrator to identify the collector onscreen.
If the administrator sees the collector, the installation is complete.
If the administrator does not see the collector, proceed to the troubleshooting section of this manual.

Power

AC Power

The CCU4 collector operates on a 120 VAC, 60 Hz supply only. The collector is double insulated and does not require an earth ground connection.
The collector input AC connector is a five position circular 3A/300V connector. Pins 2, 3 and 4 are voided for high voltage line to line clearance. The five position circular connector is mounted on the collector housing, providing a watertight connection point for external power sources.
