CHAPTER 2 FUNCTIONAL DESCRIPTION This chapter provides a brief overview of the TWACS® - ORION® system, explains how the TWACS® - ORION® system interfaces with the TWACS system, and describes the functions of the EMTR-3, HHTR-3, and ORION® transmitter. System Overview The TWACS® - ORION® system utilizes radio frequency (RF) transmission communication between an RF-enabled auxiliary meter and an RF-enabled meter.
System Overview RF communication links the ORION (located at the auxiliary meter) to the EMTR-3 (located inside a nearby electric meter.) This communication enables successful operation of the Automatic Meter Reading (AMR) system. Figure 2.1 ORION transmitter and EMTR-3 transceiver The TWACS® - ORION®system operates in the 902 - 928 MHz Industrial/ Scientific/Medical frequency band.
Chapter 2 • Functional Description Figure 2.2 RF operation block diagram RF Operation Block Diagram (TWACS-Orion Project) June 22, 2007 FCC ID: PN3Y72553-1 HHTR Data RF = PIC 18 LF242 902 -928 MHz UI = PIC 18 LF6720 8 MHz 7. 2V NiMH 1600 mAH Regulated to 5V and 3.3V PC Data Transfer from /to HHTR RS-232 HHTR Handheld Transceiver 902-928 MHz FOCUS or kV2c™ With EMTR-3 RF Interface Orion Transmitter Orion Transmitter Orion Transmitter Orion Data 916 .
System Overview During the installation and configuration process, the HHTR-3 and EMTR-3 use one or more of 51 channels spaced 322 kHz apart in the 902-928 MHz band to intercommunicate with each other. Control commands and data are input to the HHTR-3 via the keypad by the installation operator and passed to the EMTR-3 over the RF link. The EMTR-3 acknowledges transmissions from the HHTR-3 and can read back internally stored data for confirmation of receipt.
Chapter 2 • Functional Description REGULATORY DATA This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
System Overview Specifications: Table 2.1 ORION transmitter specifications ORION Specification Description Power Functional Life Expectancy 3.6 VDC embedded battery Minimum: 10 years Expected: 15 years 916.450 MHz Burst mode fixed length packet, simplex 3-of-6 100 Kbps + 1 Kbps None Frequency Shift Keying (FSK) Non Return to Zero (NRZ) Single channel (43A) 400 ft.
Chapter 2 • Functional Description RF Hardware Installation This section provides instructions for installing the RF hardware on-site. A functioning network can be created and its functionality verified before leaving the site. Pre-Installation Field Survey The field survey is used to review the environmental conditions present at any particular location and lay out the system to maximize performance. DCSI recommends that you conduct a field survey before performing the actual hardware installation.
RF Hardware Installation Environmental Conditions Optimal RF communication between the ORION and the EMTR-3 is affected by many environmental conditions. Vehicular traffic, parked vehicles in the signal path, weather conditions, construction, and even the growth of foliage may affect or degrade RF communication. Gradual loss of communication from the ORION (caused by an aging battery for example) can be detected through system checks by the TWACS Net Server (TNS) Master Station.
Chapter 2 • Functional Description • Position of the ORION® and/or EMTR-3 These are important factors in RF deployment. The ORION® antenna is omni-directional. The signal radiates 360 degrees. The EMTR-3 antenna alignment is parallel to the front cover of the electric meter, and is the most sensitive RF reception surface. Face the front of the meter/EMTR-3 toward the ORION® transmitter when possible; even on opposite sides of a building.

Use the Listen List from the HHTR-3 to determine which ORION IEDs are being heard by the selected EMTR-3. 4. Since the installer knows the ORION IED serial number, install the ORION IED using the Listen List.
CHAPTER 3 TROUBLESHOOTING This chapter explains how to test and manage typical TWACS® ORION® system problems. It is useful for installers and meter shop personnel. Foremost, it provides diagnostic information through the TNS and TWACS NG systems which give you a better assessment of problem conditions before field personnel are dispatched. There are three essential sources of diagnostic information: • The Intelligent End Device (IED) status, including leak detection, tamper detection, and port assignment.
Performing Remote Analysis (TNS) 3. Check for TNS errors that may have occurred because of commands time-out, or any software related issues in TNS that may have prevented AMR commands processing. For more information on time-out issues, see the Encode Command Parameters section in the TNS System Maintenance chapter of the TNS End User Guide. 4. Perform an On-Request AMR command to determine if the unit communicates.
Chapter 3 • Troubleshooting 8. Check the Alternate Substation tables for up-to-date information on Alternate Substations that can feed the primary sub. For more information on Alternate Substation tables, see the Adding Alternate Substation Information section in the SCE Maintenance chapter of the TNS End User Guide. Also see the Alternate Substation Mapping and Creating and Using Alternate Path Tables sections in the Building and Searching Alternate Paths chapter of the TNS Operational Process Guide.
Performing Remote Analysis (TNS) 2. Click the MIT on Request window. button to view the MIT On Request 3. Click the drop-down arrow to the right of the Serial Number field. 4. Click a serial number to select it and populate the remaining fields. 5. Double-click the TNS field for a description of the TNS status code. The following table presents common TNS status codes along with brief descriptions of those codes. Table 3.
Chapter 3 • Troubleshooting Performing Remote Analysis (TWACS NG) Complete the following steps to determine if a field visit is required for an unresponsive meter. You can end the procedure at any step and correct the problem when a cause of failure is determined. 1. If communication fails to the transponder, check the path and search state of the transponder by following the path System Monitoring > Edit Path > Search States. 2. Type in the serial number of the transponder and click Lookup.
EMTR-3 Diagnostic Indicators EMTR-3 Diagnostic Indicators The following table lists the error code number and error message text that the HHTR displays when the specific error is encountered while communicating with the EMTR-3. Table 3.2 Error code descriptions and solutions Error Description Solution The following error codes are RF communication errors. 01 RF Error General error. 02 Service Not Supported Service is not supported. 04 Operation Not Possible RF error. 05 Inappropriate Action RF error.
Chapter 3 • Troubleshooting Table 3.2 Error code descriptions and solutions Error Description Solution 223 Extract Failed The HHTR was unable to extract the port list from EMTR. The PC upload operation was aborted by the operator or there was a communication timeout. Retry the command 230 PC Upload Incomplete Resolve any communication errors. Check cable. Ensure PC application is functional. Retry the command.
Field Troubleshooting Field Troubleshooting Distribution Control Systems, Inc. has developed various software and hardware products for testing TWACS-enabled devices in the field and the meter shop. See Meter Shop Test System on page 66 of this chapter for information regarding use of this system. The EMTR-3 has no field serviceable parts. It can only install, delete, or query installed ORION transmitters.
Chapter 3 • Troubleshooting Addressing Common Field Problems Three problems often encountered in the field are: an EMTR-3 that doesn’t communicate, an EMTR-3 that doesn’t knit, and an HHTR-3 unit that displays a “time out” message. The following sections focus on these errors. EMTR-3 Does Not Communicate You must first determine whether or not the ORION® Intelligent End Device (IED) is communicating. Verify this using the ORION Connect™ software in the Radix handheld device or the drive-by device.
Meter Shop Test System HHTR-3 Times Out If the HHTR-3 times out, verify the EMTR-3 serial number is correct. If the number is correct, place the HHTR-3 directly in front of the EMTR-3 to guarantee a clear communication path, and try again. If the HHTR-3 continues to time out after trying this, RF traffic may be exceptionally heavy, and the density is preventing good communication. Wait awhile and try again. If the HHTR-3 continues to time out, there may be a problem with the HHTR-3 or EMTR-3 firmware.
