Inspection (refer to 96-0072, Retrofit Meter Quality Acceptance Criteria)3.1 Inspect the meter and cover for the following:- Meter and cover cleanliness, and no moisture inside the meter base- Unacceptable base damage- Lightning arrestors are in place and undamaged- Filters are in place- Cover seal (gasket) is in place- Insure that the meter is not unidirectional -Verify that the hi-pot barrier is in position3.2 Verify that the AEP code on the label matches the meter type:3.3 Module Inspection: Make sure the green PCB board is securely screwed into theBAMM/BAMMCCSK enclosure. There should be no visible gap between the top edge of thePCB and the top edge of the plastic enclosure.4. Module Disassembly4.1 Carefully remove glass cover from meter.4.2 Remove screws from module using a Philips #2 Screwdriver. Always use a manualscrewdriver when unscrewing the module from the meter in order to prevent debris fromfalling into the meter.4.3 Carefully place module facedown on the ESD mat on the workbench after disassembly.Figure 1 BAMM InterrupterNote: Place ESD wrist-straps on prior to module disassembly procedure.
MPI: GE, 240v, Single Phase, Remanufacturing Process97-xxxx, Rev:A Page 5 of 13 5 AC Cable Disconnection5.1 Disconnect AC cable from the module. Use needle nose pliers to disconnect powerleads from module. Gently grip on red AC cable tabs with needle nose pliers anddisconnect the power leads. Pay close attention not to touch PCB with pliers and not tobend connection tabs on the board. Do not rotate tabs when disconnecting power leads.(Refer to Figure 2)5.2 Disconnect AC cables from Current Coil. Use needlenose pliers to disconnect powerleads from current coil. Grip on the edge of the superclip and gently remove clip fromcurrent coils. Remove any debris resulting from disassembly of the superclip from thecopper coil.5.3 Disregard and discard old cables.5.4 All disassembled modules must be placed in ESD bags for storage.Note: Old modules (RTOMM) have a different set of cables from the new generation of modules(BAMM/BAMMCCSK). Both types of cables are NOT exchangeable. The RTOMM cables havedifferent inline components on each of the two cables. One of two RTOMM cables has a fuseincorporated on the cable and the other cable has a resistor incorporated on it. TheBAMM/BAMMCCSK have 2 identical cables WITHOUT in line components.RTOMMComponent SideResistor cableconnectorFuse cableconnectorFigure 2: Power CableOrientation

Operation is subject to the followingtwo conditions: (1) This device may not cause harmful interference, and (2) this devicemust accept any interference received, including interference that may cause undesiredoperation.This device must accept any interference received, including interference that maycause undesired operation.The BAMMCCSK module is factory installed and is inaccessible to the user. Themodule must be sent back to the factory for any retrofit or maintenance required.The antenna used for this transmitter must be installed to provide a separation distanceof at least 20cm from all persons and must not be co-located or operating inconjunction with any other antenna or transmitter.The BAMMCCSK module is designed to transmit only using one loop antenna havingomnidirectional gains of not more than 0 dBi.7.1 Power Cable InstallationNote: Make sure to use the correct AC cables. The 240V BAMM and BAMMCCSK use theblack AC cables WITHOUT the in-line components. Refer to the addendum part ofthe MPI for the soldering procedure ond 120V GE Meters.7.1.1 Using the wire installation tool grip the superclip along its ears, open the pliersand place the clip onto the current coil, near the end on a straight portion of thecoil. When attaching the superclips to the current coil, install the clips as shownin the diagrams below, with the wire exiting the superclip towards you.Notes:1. Never place a superclip over the insulated portion of a current coil.2. Jaw opening on the clip installation tool must be set to predetermineddimension:a) for GE I70 S-I, jaw opening = 0.22b) for GE I70 S-II, Jaw opening = 0.343. It is preferred to have all clip prongs engaged with the current coil. Onsome meters, due to size of current coil and clip, the upper prongs do notbecome engaged. Acceptance criteria for clip engagement is: Clip must not slip on current coil by pulling (slight tug) on the wire.

Repeat for the other cable.Note: Do not attempt to straighten a BAMM/BAMMCCSK fast-on tab that is bent. If thefast-on connector cannot be fully seated onto the tab because the tab is bent toomuch, reject the BAMM/BAMMCCSK.8. Interrupter Installation8.1 Insert the interrupter into the interrupter installation tool as shown below. It is importantthat the interrupter and the interrupter tool are properly oriented. Handle the interrupter from long side of hub not the interrupter blades. Donot touch the interrupter blades as you insert the interrupter into the tool.Figure 3: Interrupter Installation8.2 Carefully position the interrupter next to and parallel to the meter shaft with the spacerside 2of the tool resting totally flush on the bottom of the meter disk. Use your finger orthumb to press the tool totally flush against the disk when you snap the interrupter ontothe disk.8.3 Verify that the installation tool is held perfectly vertical, then gently squeeze the pliers untilthe interrupter snaps onto the meter shaft. If you don’t feel or hear the ‘snap’, theinterrupter might be damaged or in the wrong position. interrupterletter ‘G’on this sidelong sideof hubmeter diskfinger pressure
MPI: GE, 240v, Single Phase, Remanufacturing Process97-xxxx, Rev:A Page 10 of 13 8.4 Remove the interrupter tool from the meter base. Make certain that the interrupter bladeis not twisted while removing the tool. Gently release the tool from the interrupterbefore removing the tool from the meter.8.5 Using 0.025” feeler gage, check for interrupter blade- meter base clearance. Theclearance should be checked for all blades and meter base on both sides of shaft. Ifclearance is less than feeler size(0.025”), the interrupter must be removed and a newinterrupter installed. Repeat interrupter placement procedure. If the clearance is still lessthan 0,025place the meter aside and do not reuse meter. Acceptable versusunacceptable contact can be evaluate by inserting the feeler gage between the interrupterand the base without touching the disk or interrupter with anything else. If the interrupterand disk rotate even slightly when the feeler gage is inserted, there is unacceptablecontact. Place the feeler gage closer to the end of the interrupter blades rather thancloser to the disk shaft because the webbing of the interrupter could give afalse failure reading.Figure 4: Checking Proper Interrupter Instalation9.0 BAMM/BAMMCCSK Installation9.1 Take the new barcode label and attach it to the front face of the BAMM/BAMMCCSK.Make sure the label is square and does not interfere with any holes or writing on theenclosure. Verify the quality of the label print and the utility meter ID on the label matchesthe original label on the module. If there is a discrepancy between old and new label serialnumber, investigate the problem and print and attach the correct label.9.2 Position the BAMM/BAMMCCSK onto the meter standoffs by rotating theBAMM/BAMMCCSK upwards and over the interrupter. Use the electric torque driver (set to5 in-lbs) to secure the TOMM to the meter using two module mounting screws. Be verycareful not to damage the screw heads.9.3 Again rotate the disk gently to verify that there is no interference with the interrupteragainst the meter or BAMM/BAMMCCSK. meter basegood location to place feeler gage.meter passesbad location to place feeler gage.meter OK, but fails test
