KCHMXU510Radio Transceiver For Meter Reading System

The following information contains installation instructions for the Invensys RadioRead T Meter Transceiver Unit (MXU). The wiring con- nections are the same for both inside and pit set installations. Tech- niques may be different for the actual MXU placement in each type of installation. Note: This installation sheet is only for installation of the RadioRead MXU. For instructions on installing other AMR devices, please request and refer to the individual installation instructions for those devices. c SR II ® security screw socket with 1/4" nut driver or ratchet wrench c 3M Scotchlok ® UY-2 butt connector “gel-caps” c 3M Scotchlok ® E-9Y stepped jaw crimping tool with wire cutter c Wire stripper tool c Screwdrivers (Phillips and standard blade heads) c Power drill and bit (1/4") c 8 x 1" sheet metal screws c 1/2" Electrical Metallic Tubing (EMT) c Conduit cutting tool c Hammer c Conduit driver (available from Invensys) c Three-conductor solid wire (Invensys specification) I MPORTANT R ECOMMENDED T OOLS AND M ATERIALS 1 of 2 MXU Model 510 - Installation Wiring Diagram The MXU also requires proper programming of each port to match the device that is connected to the respective port. Refer to Invensys Pro- gramming Manual AMR-988. The MXU wiring instructions assume the utility meter with an encoder register or MultiRead module has been installed and the proper wire has been run to the MXU installation location. Three-conductor, 22 gauge, solid conductor cable is recommended. (For meter installation, refer to the installation information included in Invensys meter shipping cartons.) 1. Using the SR II security socket with ratchet wrench or nut driver, open the MXU enclosure by removing SR II type security screw. Bottom part of enclosure will contain the MXU battery and top part the electronics and connection wires. Connect the three wires from the encoder register or MultiRead module to the matching color wires on the MXU and the desired port. If not already done, strip approximately 2" off outer jacket of the encoder wire cable. The wire colors for each unit should be green , red , and black . Insert two matching color wire ends – red to red , green to green , and black to black into a UY-2 gel-cap with the color button of gel-cap facing away. (This provides a better view of wire positions inside the clear plastic gel-cap enabling the installer to see the wires are com- pletely and properly inserted.) Note: For the Schlumberger Proread encoder, the color coded wire connections are not standard – For Proread, connect the MXU red to Proread black, MXU green to Proread red, and MXU black to Proread green. Using gel-cap pliers, squeeze the gel-cap. This will splice the two wires and release the waterproof gel to seal the connection. The splice can be checked by pulling gently on the gel-cap while hold- ing the wires to be sure they are tight and secure. Repeat Step 2 instructions for the remaining two wire connections. Repeat con- nections to a second port, if required. * If any of the wire connections are not being used they should be capped at the end with a gel-cap. This is to prevent water intrusion via wicking through the exposed wire ends. The red , green , and black wires must be gel-capped individually. The green with white striped TouchRead sensor wires can be gel- capped together. Note: A Schlumberger Proread (ARB VI) register must be con- nected directly to an MXU port. The Proread register will not work through a MultiRead module connected to an MXU. 2. Connect the battery to the MXU electronics. Using the gel-cap con- necting technique described in Step 2 above, connect the red and white stripe wire from the battery to the red and white stripe wire from the MXU electronics. Repeat the procedure for the black and white stripe wire from the battery to the black and white stripe wire from the MXU. Caution: DO NOT cross connect the black and white and red and white stripe wires of the MXU and battery pack as this may cause damage to the MXU electronics. If using the optional TouchRead ® connection, go to Step 3. If not, skip to Step 4. 3. (Optional) TouchRead ® Connection (available for Invensys register encoders only) – The MXU includes a built-in TouchRead splitter connection to allow the encoder register to be interrogated by both RadioRead equipment and a remote TouchRead System sensor. I NSTALLATION - W IRING I NSTRUCTIONS The Model 510 MXU incorporates a two-port interface design. Hard- wire connections to either port from a compatible utility meter or Multi- Read module is the same for each port. Note: the wiring is different when connecting a Schlumberger Proread (ARB-VI) encoder to a port.

Note: If three-conductor wire cable is used, the third wire is not utilized for the TouchRead Connection. At the TouchPad connection, connect the same two wires to the terminal screws on the back of the TouchPad. Caution: Be sure there is no bare wire-to-wire contact. (The TouchRead connection is non-polarity sensitive and will work as long as the same color wires are used at both ends of the connection. If three-conductor wire is used, be sure the third “dead” wire is not mistakenly connected at either end.) Repeat the connections for a second port if required.

From: Tom Cokenias [[email protected]] Sent: Monday, January 13, 2003 11:23 AM To: [email protected] Subject: Invensys Metering Systems, FCC ID:KCHMXU510, AN02T2456 Mike, Please get back to me on whether answers to 1 and 2 are ok. Invensys needs this by the end of the week. Answer 3 I am waiting from Tim Harrington per his email below. If I don't get an answer Invensys instructed me to go ahead with the 20 cm statement, but they are not pleased with it: Question #1: Internal photos is listed in the request for confidentiality letter. It is FCC policy not to grant internal photos as confidential document. Please remove this request and provide revised letter. ANS1 The entire unit will be enclosed in black opaque potting material. The circuit boards woudl be ruined if one tried to remove the potting solution from a production unit. As such, an interested party would not be able to view the circuit boards, hence this request that photographs be kept confidential. Question #2: Page 3 of test report ( Radiated spurious emission tabular data @ 903.8 Fundamental frequency ), the average reading of fundamental frequency is 11.2 dBuV/m but the peak reading is 94.1dBuV/m. Please explain the huge difference between peak and average reading. In addition, average reading of fundamental is lower than spurious emissions which does not comply with 15.215(b) requirements. ANS2. The entry was a typo, it should have been 111.2 dBuV/m. Attached is corrected data sheet. Question #3: There is no RF warning statement in the user manual, suggest wordings may be " IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter." Please provide revised user manual to comply this requirement.

The EUT was placed on a wooden table resting on a turntable on the open air test site. Several utility meters were connected to the appropriate ports as typical loads. The search antenna was placed 3m from the EUT. The EUT antenna was mounted vertically as per normal installation. 2. The turntable was slowly rotated to locate the direction of maximum emission at each emission falling in the restricted bands of 15.205. 3. Radiated emissions were investigated for a LOW channel, a MID channel, and HIGH channel. Emissions were investigated to the 10 th harmonic. 4. Once maximum direction was determined, the search antenna was raised and lowered in both vertical and horizontal polarizations. The maximum readings so obtained are recorded in the data listed below. Test Results: Worst case results are presented. Refer to data sheets in separate attachments. Restricted band emissions meet 54 dBuV/m. Other undesired emissions from the transmitter meet the -20 dBc requirement in 15.247(c).
