Support 10 DCU Maintenance and Operation Manual
Chapter 3 • Introduction CHAPTER 3 INTRODUCTION The Aclara RF™ or system is an automated system for taking reads from individual residential and commercial meters and sending them to a central computer where consumption can be viewed, analyzed, and integrated with a utility’s other systems, such as billing.
Data Collector Unit (DCU) Data Collector Unit (DCU) A Data Collector Unit’s main purpose is to capture, store, and transmit meter readings from endpoints. DCUs are tuned to receive on the same frequency that the endpoints broadcast their readings. DCUs are installed to facilitate overlapping endpoint coverage, and endpoint readings are captured by multiple DCUs. The DCU can collect from, and transmit to, electric, gas, and water devices simultaneously.
Chapter 3 • Introduction Fiber A direct fiber connection is also available in the DCU 2+. See additional details in the DCU Installation Instructions, Y20977-TUM for details on wiring and connection. A fiber connected DCU supports up to a 100 Mbps data speed. Failover Backhaul Failover backhaul is a feature that Aclara’s DCU 2+ now provides as a means to switch between a primary and secondary backhaul should the primary backhaul fail.
Data Collector Unit (DCU) NOTE Certain information is limited to factory or over-the-air (OTA) changes and cannot be changed through a local menu.
Chapter 3 • Introduction When operating in the low power mode, the DCU 2+ compares the battery state-of-charge to the seasonal state-of-charge threshold every 60 minutes. Initial battery protection settings are automated based on GPS-provided latitude and longitude and will only be recalculated if the GPS coordinates change by more than 1 degree in magnitude.
Data Collector Unit (DCU) Version 2.08 dynamically switches the battery current on and off, significantly increasing the possibility that the 5 minute readings occur when the battery is not being charged, even if for a few seconds. So if all the charge current reading are less than zero in an hour, the records will be zero for that hour.
Chapter 3 • Introduction This event is more likely to be seen when the battery is at a higher charge level (to prevent life-reducing overcharge) and thus is more likely in the summer months compared to the winter months. We understand that some customers use the charging current data to determine if a DCU’s charging capability has been impacted and this may provide false positive alerts.
Data Collector Unit (DCU) Power Management NOTE This applies to DCU 2 models with firmware version 2.88 or later. VI - Limited functionality voltage threshold (default 12.0V) Vs - Suspend mode voltage threshold (default 11.6V) Vh - Voltage hysteresis 0.

Chapter 5 • Maintenance CHAPTER 5 MAINTENANCE The Data Collector Unit (DCU) is designed to minimize maintenance requirements. Performance of the DCU can be monitored via the diagnostic information sent regularly to the AclaraONE headend. DCU battery voltage, charging current, temperature, and radio frequency interference can be monitored through AclaraONE displays, which allow quick detection of problems such as faulty batteries, damaged antennas or solar panels.
Inspecting the Site of supporting 4,000 pounds or more will suffice. The chain may be secured with removable links. It must be attached to a structural building member (such as an I-beam) capable of supporting several thousand pounds. Inspect the Lock If the DCU is within 8' of the ground, or in a public area, it must be locked according to OSHA standards. Upon arrival ensure that locks and/or tamper evident seals are in place.
Chapter 5 • Maintenance Antenna Clearance New construction may cause objects to be installed near the antenna. The antenna must be mounted clear of metal objects in the horizontal plane for a distance of one antenna length. Any metal in the radiation area will result in a corresponding RF shadow on the map. The headend may be used to issue trace route commands to endpoints which are likely to be affected. The antenna may have to be repositioned to provide a better line of sight to the affected units.
Servicing the DCU Servicing the DCU The engineers at Aclara have developed a set of expectations regarding how the DCU should be maintained. The following table summarizes the types of activities a technician would be expected to perform based on the nature of the visit.
Chapter 5 • Maintenance Tools & Equipment Required The tools listed below are recommended for the maintenance and repair procedures in this chapter. • Band strapping tool • Phillips head screwdriver • Inch-pound torque wrench • Diagonal cutting pliers Routine Checks When it is necessary to visit a DCU installation site for maintenance, the following checklist provides a guideline for performing a thorough visual inspection of DCU internals. High voltage hazard.
Repairs Repairs Repairing the DCU Be sure to note all repairs and changes to the DCU in the maintenance log. For safety reasons, any repairs described in this section should begin with the unit completely powered down (including disconnection from the battery) prior to commencing the repair. When the DCU is powered down, its backhaul will also go off-line. The AclaraONE headend will be able to detect that the DCU has gone off-line and will show an off-line status on the user screen.

A PPENDIX A TESTING THE DCU This section lists a variety of different tests. Select the test(s) appropriate for your situation. Every visit does not require that every test be conducted. DCU Antenna Pattern Test If the DCU has been found to be able to reach some locations, but not reach others, additional testing of the DCU antenna pattern may be necessary. This test is used to measure the effect that metal near the antenna may have on the omnidirectional pattern expected from the installation.
DCU Antenna Pattern Test Field Data 1. Connect an RF power meter (input) to a calibrated signal generator (output). 2. Transmit 460 MHz energy from your signal generator into your power meter and confirm that the power received agrees with the power transmitted. 3. Remove your calibrated signal generator from the power meter and connect it instead to the coax and antenna (in place of the DCU). 4.
Testing the DCU Plot the results, and examine for omnidirectionality, as well as expected signal strength. Measurements taken at 3m or 10m can be compared to the table below for anomalies. Conducted Power (W) Antenna Gain (dBi) ERP (W) EIRP (W) dBµV/m @ 3m dBµV/m @ 10m 1.0 1.5 2.0 7 7 7 3 4.6 6.1 5.0 7.5 10.0 132.2 134.0 135.2 121.7 123.6 124.8 Measurements taken at some distance must be compared to a propagation study.
Calibrating the DCU’s RSSI Measurement Calibrating the DCU’s RSSI Measurement This test should be run initially upon installation, and periodically (every 5 years). It should be run on a day when the outdoor temperature is reasonable. Tools required: • A laptop (or tablet) computer equipped with a cell card • A calibrated spectrum analyzer (SA) with real-time signal capture • A signal splitter • Two identical lengths of coaxial cable which are short 56 1.
Testing the DCU Testing the Coax and Antenna The coax and antenna will have been tested by the installer. If, over time, the performance of the DCU has degraded, testing of the coax and antenna may be warranted. It is quite possible over time that moisture or corrosion has affected the coax and the system's RF performance. The coax and antenna should be periodically tested to ensure the system is performing within recommended limits.
Testing the Coax and Antenna Return Loss (Antenna System) After confirming that the coax meets specifications, remove the calibrated short and attach the antenna to the coax. With the instrument connected to the lower end of the cable, sweep the assembly which now includes the mainline, jumpers, and antenna. Set markers to frequency range boundaries in use on that line (450-470 MHz). Test Analysis Save the results of these tests and name the file. Pass criteria: 1.
Testing the DCU Spectrum Analysis It is occasionally useful to capture a baseline measurement of the newly installed antenna before the DCU becomes operational. This is particularly true if the antenna is suspected of potentially having issues due to a nearby transmitter. A spectrum analyzer should be connected to the lower end of the coax and tuned to listen in the 450-470 MHz band.
Testing the Backhaul 1. Use a browser on a laptop or tablet computer (equipped with cell card) to login to the utility's corporate network, and login to a session of AclaraONE. 2. Check the status of the DCU to determine if it is considered on-line. Set it to on-line if it is off-line. 3. Issue a trace route command to the DCU (with the DCU as the target). 4. Examine the results of the trace route to ensure the backhaul is operational.
