chapter provides an overview of function, meter compatibility and product marking. 1.1 GENERAL The RAMAR TransPondIT for the CENTRON meter implements the TransPondIT functionality into the Itron (formerly Schlumberger Electricity, Inc.) CENTRON solid state electricity meter. It is a personality module with the functions of meter, register, display and RF Transmitter. The TransPondIT is supplied fitted with the LCD and meter face plate. Mounting of the TransPondIT in the meter takes only a few seconds and requires no tools and minimal operator training. The TransPondIT is fitted to new or existing meters in utility meter shop or by a 3rd party meter service company. Alternatively, utilities can buy meters with the personality module already installed. If settings on the TransPondIT need to be modified, an electric ConFigIT is used to reconfigure the TransPondIT prior to sealing the meter. 1.2 METER COMPATIBILITY The CENTRON meter features several meter bases in a number of form factors. Appendix A includes a table of TransPondIT part numbers used with the various meter form factors. If purchasing meters for fitting TransPondITs, order meters without the standard personality module (C1SX). Qualification of the meter with TransPondIT fitted is still pending for some form factors. TransPondITs are available for order with a tilt switch option – refer to your RAMAR representative for availability. The tilt switch reports removal of meter or inverted operation of the meter. 1.3 KIT CONTENTS The items in the TransPondIT package are: • TransPondITs • Sheet of Approvals labels • Sheet of ‘X10’ labels Technical Reference Manual - TransPondIT for CENTRON Electric Meter 1.4 TRANSPONDIT MARKINGS Product Label Figure 1: TransPondIT markings and information The TransPondIT is identified by a label applied to the meter faceplate.

DO NOT touch the LCD display or the electronics components. 2.2 INSPECTION Perform the following inspections when you receive the TransPondITs: • Compare and verify the TransPondIT serial number and part number (see Figure 1) to the packing slip and invoice. • Inspect for damage to the LCD plastic housing, LCD and PCB. • Peel off protective strip from LCD. 2.3 METER PREPARATION Perform any cleaning and preparation to the meter prior to fitting the TransPondIT. 2.4 SAFETY The TransPondIT is powered via connections to the meter’s metrology board. The connection is achieved using a board-to-board connector supplied with the meter. Do not power the meter from mains without the inner cover in place. Remove power from the meter before removing the inner cover. Technical Reference Manual - TransPondIT for CENTRON Electric Meter 2.5 TRANSPONDIT INSTALLATION To change or fit the TransPondIT: 1. Remove power from the meter. 2. Remove the outer (polycarbonate or glass) cover (twist off). 3. Remove plastic inner cover by holding the meter with both hands and applying equal pressure on either side of the three and nine-o’clock positions (see Figure 3a). The inner cover is held in place by four plastic tabs on the meter base. 4. With the meter facing the user and the plastic tabs disengaged, tilt the cover away (see Figure 3b). 5. Lift off the meter base taking care not to catch the light pipe. The light pipe could be damaged if you lift the cover straight up (see Figure 3c). Figure 3a Figure 3b Light Pipe Figure 3c Figure 3a, 3b, 3c: Removing the inner protective cover 6. Remove the black board-to-board connector between the upper circuit board (if present) and the metrology board. Grasp the board in the middle, lengthwise, and pull out by moving from side-to-side (see Figure 4). To maintain the integrity of the connector, only remove it when fitting TransPondIT. Board to board connector Figure 4: Removing the board to board connector Technical Reference Manual - TransPondIT for CENTRON Electric Meter 7. Remove the upper circuit board (if fitted), one side at a time, by pulling gently outwards on the meter frame snaps (see Figure 5) while lifting the module up. Meter frame snaps Figure 5: Meter frame snaps 8. Snap the new module into the meter frame by aligning the notches at the bottom of the circuit board with the lower two snaps (see Figure 6). PCB lower notch Lower meter snap Figure 6: Alignment of PCB notch with meter snap NOTE: The module must be aligned properly in the snaps to avoid damage to the connector or circuit board. Technical Reference Manual - TransPondIT for CENTRON Electric Meter 9. Replace the board-to-board connector by aligning the top of the connector with the notches in the circuit board (see Figure 7) and pressing gently at the bottom of the connector to mate with the metrology board (see Figure 8). The board-to-board connecter can be used either way up. Then, gently press the top of the connector to mate it to the TransPondIT (see Figure 9). The connector is seated correctly when you hear it snap into place Circuit board notches Figure 7: TransPondIT circuit board notched Note: Use the meter base for leverage instead of the LCD holder. Pressure on the LCD holder may damage the TransPondIT Figure 8: Board-to-board connector: BOTTOM Figure 9: Board-to-board connector: TOP 10. Ensure the board-to-board connector is fully seated by pressing firmly on the middle of the connector. 11. Carefully replace the inner protective cover. Engage the top snaps first, taking care to place the slot at the top of the cover over IR light pipe. Failure to do so could break the light pipe. Ensure that the four meter base tabs are engaged with the top and bottom of the inner cover. 12. Apply the approvals label at 9 o’clock position in such a way that the bottom of the text is parallel with base of meter (see Figure 2). Technical Reference Manual - TransPondIT for CENTRON Electric Meter 13. If configuration settings need to be modified, configure using the instructions in Chapter 3. 14. Replace the cover over the meter base until the flange on the cover is flush with the flange on the meter base. 15. Turn the cover 1/8 turn clockwise until the locking tabs are fully engaged with the meter base. 16. Fit new meter tamper seal through holes in meter base. (see figure 10) Figure 10: TransPondIT installed in meter and location of meter seal tag Meter Seal Tag Technical Reference Manual - TransPondIT for CENTRON Electric Meter Chapter 3: CONFIGURING THE TRANSPONDIT 3.1 DEFAULT CONFIGURATION TransPondITs are delivered with the following default configuration: Parameter Meter Reading (kWh) Utility Code TransPondIT ID Transmit Interval Status/Error/Tamper Code Display format Detent option LCD segment test Default Setting 55 Factory Serial Number (on barcode) 5 seconds OK (0) 5*1 Decrement meter reading on reverse energy flow KWh for 7 seconds, segment test for 1 second Table 1: Default TransPondIT configuration If these settings are acceptable then the TransPondIT is ready to use. If the settings are not acceptable, then the ConFigIT is used to re-program the TransPondIT. 3.2 CONFIGURABLE PARAMETERS The following parameters can be configured: • TransPondIT ID – (Example: to match the meter ID or to match Meter Point ID (0-16777215)). • Meter reading (0 to 99999). • Utility code – (Example: to provide differentiation from TransPondITs on water/gas meters or from those in neighboring utilities (0-255)). • Format of the kWh reading on LCD (5*1 [kWh] or 4*10 [10’s of kWh]). • Reverse count handling function (detent register function). • LCD segment test function. • Status/Error/Tamper code. Technical Reference Manual - TransPondIT for CENTRON Electric Meter 3.3 PREPARATION OF CONFIGIT The TransPondIT is configured by RAMAR’s ConFigIT electric serial adaptor. The ConFigIT interfaces to the TransPondIT using a physical cable connection. The ConFigIT powers the TransPondIT during configuration - TransPondITs can be configured either on the bench (out of meter) or in the meter. The TransPondIT should not be mains powered during the configuration process. The ConFigIT kit includes: • ConFigIT box • ‘Computer’ serial cable (Connections are wired straight through, terminated at both ends with 9-pin female ‘D’ connectors – NOTE not same as for letterbox ConFigIT for Water TransPondIT). • ‘TransPondIT’ serial cable (Note: order spares from your CENTRON Meter supplier as ‘Zeroer Cable’ – Itron part no K442436-001) • CENTRON meter plug (Note: order spares from your CENTRON Meter supplier as ‘Zeroer Assy Welded’ – Itron part no K442395-001) The ConFigIT is powered by 2 AA alkaline batteries (not included in kit). The battery compartment is on the rear of ConFigIT. Another option is to power the ConFigIT with an external DC power supply (6-12VDC @ 200mA – not included in kit). The ConFigIT application must be configured so that it uses the COM port that the TransPondIT is connected to. If the wrong COM port is used, then the error message as illustrated in figure 24 is displayed. To change the COM port interface, select File – Interface from the menu and select the correct COM port. When battery operated, the ConFigIT On/Standby LED illuminates once the ConFigIT program is running and the correct COM port is selected. If the ConFigIT is not used for more than 20 seconds, the ‘standby’ mode activates indicated by a flashing On/Standby LED. The ConFigIT returns to its normal mode if there is communication activity within 60 seconds. If there is no activity before 60 seconds, the ConFigIT powers down and the LED turns off. If the ConFigIT is powered by an external DC supply, it does not enter ‘standby’ mode or power down.
