For more information on the MOSCAD/MOSCAD-L, see the System Overview manual of the MOSCAD Programming ToolBox.
Introduction years, based on six transmissions per day, zero repetitions, in 70º F temperatures. The transmitter consists of a printed circuit board installed in a plastic case, suitable for either wall mounting or pit installation. The transmitter is intended for outdoor installation. Figure 2 provides a general view of the transmitter.
Introduction Safety Handling Instructions For information on safety handling instructions, see the Product Safety and RF Energy Exposure for AMR RF Transmitters booklet, Motorola publication no. 6802974C60, which is distributed with the transmitter.
INSTALLATION General SAFETY SUMMARY NOTICE: It is recommended that the transmitter be installed such that the antenna and the transmitter are kept 7.8 in (20 cm) from passersby when transmitting. The AMR RF transmitter should be installed by qualified and authorized technicians. Federal regulations forbid air transport of an enabled transmitter. If an enabled transmitter is to be transported by air, the transmitter housing must be opened and the battery terminals and capacitor must be unsoldered.
Installation Changing the Transmitter Parameters The AMR RF transmitter is configured in the factory. If this configuration needs to be modified, use the AMR ToolBox to change the parameters, as necessary. For more information, see Appendix C below and the AMR ToolBox User Guide. Enabling the Transmitter ! Caution The AMR RF transmitter should be enabled before mounting and installation. Do not enable the AMR RF transmitter if it is to be transported by air.
Installation MAGNET Figure 3 Enabling the AMR Transmitter 3. When the magnet is removed, the transmitter is enabled and a transmission will be sent. IMPORTANT: If the magnet is held near the unit for more than ten seconds, wait another 30 seconds before once again placing the magnet near the top of the transmitter to enable it. 4.
Installation With the AMR ToolBox The transmitter can be enabled and tested using the AMR ToolBox. 1. Connect the transmitter to the programmer unit as shown in Figure 11 in Appendix C. 2. Place the magnet for more than 10 seconds near the top of the transmitter and remove it. This will put the transmitter into programming mode. 3. Select the Transmitter in the AMR ToolBox menu panel and click on the Connection Check icon in the icon bar (or select the Connection Check command from the Comm menu.) 4.
Installation Recording Counter Values/Readings Initial Recording ! Record the initial meters reading and counter value AFTER installing the transmitter. Caution The transmitter maintains a pulse counter which is advanced with every pulse of the meter. This counter is used in the Host for data collection. After the transmitter has been installed, the initial value of that counter along with the actual reading from the meter display, must be recorded in the Host. 1.
Installation 2. Connect the transmitter to the programmer unit as shown in Figure 11 in Appendix C. 3. Using the AMR ToolBox, change the required parameters (as described in Appendix C and the AMR ToolBox User Guide.) 4. Reconnect the transmitter to the meter and read the meter reading (from the display of the meter). 5.
Installation Dimensions The dimensions of the transmitter are: width – 3.86" (98 mm), height – 4.77" (121 mm), depth – 1.8" (45.5 mm), weight – 8.82 oz (250 g) maximum (see Figure 4). 3.86” 98 mm 45 1.8” .5 mm 4.77” 121mm Figure 4 Dimensions of AMR RF Transmitter Wall Mounting ! Caution ! Caution The AMR transmitter should be enabled before mounting. See the Enabling the Transmitter section above.
Installation The AMR transmitter can be installed on the wall using screws. Before installing, verify that there is sufficient space around the transmitter. Allow 6.3" (16 cm) from the bottom of the transmitter for the antenna. The AMR transmitter can be mounted on the wall using screws, as shown in Figure 5 below. 1. Position the AMR transmitter as high as possible on the wall. 2. Secure with two stainless steel self-tapping screws (ST4.2, pan head) and two stainless steel flat washers, inner diameter: 0.
Installation 3. Connect the transmitter wires to the meter wires, using gel cups (not supplied) to seal the connection. Use a 3M™ recommended tool to squeeze the gel cup until the connection is sealed. - If the meter wires are floating, connect the two data wires to the meter wires. - If one of the meter wires is connected to the ground/common (-), connect it to the black wire on the transmitter and connect the green wire to the switch (+). The transmitter wires are 18" (45.7 cm) long.
Installation Pit Installation ! Caution ! Caution The AMR transmitter should be enabled before installing. See the Enabling the Transmitter section above. Before installing the AMR transmitter, make sure that the transmission frequency and transmissions rate are appropriate. If not, reprogram as described in Appendix C and the AMR ToolBox User Guide. The AMR transmitter can be installed in a meter pit with a metal or plastic lid. Before installing, verify that the available space is at least 10" (25.
Installation 1. Remove the lid from the pit. 2. Drill 1.1" or 1 1/8" hole in the flat portion of the lid. (The flat portion should be at least 3.54 sq. in or 9 sq. cm.) Remove burrs from the edges of the hole. 3. Spread any type of RTV sealant on the bottom of the antenna cover. Apply sealant here Hole for Antenna Figure 7 Antenna Cover 4.
Installation Antenna Cover Pit Lid Bracket Wire Hole Washer Nut Figure 8 Bracket Attached to Pit Lid ! Do not exert torque of more than 40 ± 5 in-lb on the nut or it may be damaged. Caution 7. Invert the lid and bracket and place carefully on the ground, resting the full weight on the top of the antenna cover (with the Motorola symbol). 8.
Installation Data Wires Bracket Transmitter Ejot M4x14 Screws + SST Washers Nut Spring Washer Pit Lid Top Protective Antenna Cover Figure 9 AMR Transmitter Mounted on Pit Lid 10. Thread the transmitter input wires through the small wire hole at the base of the bracket (see Figure 8) OR attach transmitter wires to side of bracket, threading a strip (not supplied) through the small wire hole at the base of the bracket. 11.
Installation ! Caution To ensure that moisture does not damage the transmitter, gel cups must be used to seal the connection between the data wires and the meter. 12. Replace the lid on the pit with the antenna cover facing up. ! Caution The plastic bracket can withstand the weight of the lid (up to 330lb/ 150 kg). Care should be taken not to exert more than this weight or else the bracket might break.
THE AMR RF TRANSMITTER Overview The AMR RF transmitter contains a UHF radio (450470MHz 12.5 KHz bandwidth) and a logic circuit interface to a single pulse-type meter. The transmitter includes an internal lithium battery.
The AMR RF Transmitter Communication The transmitter communicates via receiver/ repeater or programmer units in two ways: Meter data is sent via one-way UHF communication to a receiver. When the data input wires of the transmitter are connected to a programmer unit which is connected to the AMR ToolBox PC, programming commands are received from the ToolBox and transmissions are sent to the air. See Appendix C for details. Connectors The AMR transmitter has one internal connector for the data input wires.
The AMR RF Transmitter The transmitter sends a battery status signal as part of its transmission. When a low battery indication appears, the transmitter has enough calculated power for approximately five months ( ± 3 months) of normal operation.
