Chapter 1 Introduction 1.1 Purpose and Use The Miltel Transmitter (FCC ID: MLLCPTX450A) is a data link transmitter that is used for data acquisition in Miltel’s telemetric data collection system. This device is installed on-site by a professional field technician, thus it includes technical terms. The equipment is not to be installed by a non-professional individual that has not been trained and authorized. 1.
Chapter 2 Theory of Operation 2.1 General Description The Miltel CPTx is the first link in the data collection system. It is an independent unit that does not require an external power source, wiring, or the preparation of any special infrastructure. The unit is installed in proximity to the physical sensor and can be connected to several different sensors in parallel (for example four water meters of adjacent apartment, three ground moisture sensors at different depths, etc).

The controller gathers the data for 10-240 minutes before initiating a transmission. If any of the counters/sensors has exceeded a preset value, or any alarm (such as tamper) has been received, the controller generates a single message immediately. Any further message will include alarm information along with counter data, if alarm condition still exists. Note: The duration interval between two transmissions is always greater than 30 minutes.

Chapter 4 Installation Instructions 4.1 General The Miltel Transmitter is installed by a professional technician. Several possibilities for installation have been programmed into the system in order to provide solutions for installation of various types of sensors including water, gas or electric meters. 4.2 Installation 4.2.1 Enclosure Type B For on-site installation of the Miltel Transmitter Type B device, proceed as follows: 1) Mount the back plate to the wall using two mounting screws.
2) Splice the wires coming from the transmitter with the wires coming from the meter (Important: Keep the color coding consistent). Splice Wires 3) Close the enclosure by placing the transmitter box (grey) over the base plate (black) and fasten with one screw. Screw 4) Perform a functional radio transmission test by touching the side of the transmitter enclosure with a strong magnet (trigger transmission). Verify correct reception of data at the base station (concentrator).
4.2.2 Enclosure Type N For on-site installation of the Miltel Transmitter Type N device, proceed as follows: 1) Mount the transmitter enclosure to the wall using at least two of the four mounting screws or Mount the transmitter on ground mounting pole. Vertical Mounting Holes Horizontal Mounting Holes Hole for optional mounting on pole Cable from Meter(s) and/or Sensor(s) (supplied with watertight connector) 2) Connect the connector(s) to the meter and/or sensor.
4.2.3 Enclosure Type S For on-site installation of the Miltel Transmitter Type S device, proceed as follows: 1) Loosen the four screws fastening the unit's box and open the box cover. 2) Install the unit's box base as required: 3) For pipeline installations (as in Figure 2-1), first attach the stainless steel clamp (see Figure 4-1) to the pipeline, close it around the pipeline and fasten the screw in the middle of the device.
8) Close the four screws fastening the cover. 9) Insert plastic protection plugs.
