 MTU150W™ General Description MTU150W™ is a long-range, synthesized radio-metering transmitter in the VHF 450- 470 MHz frequency range. When the MTU150W detects pulse conditions at one or more of its inputs the pulse is counted and saved. When the number of the pulse is equal to the Trans Scale defined by the GUP10™, it is then transmitted to the central station according to the WAT-NET TM protocol selected for the system in operation. MTU150W™ has one connector (see Figure 1). 1. J9: The 10-pin programming jack is a serial port to connect a PC or a FTU (see Figure 1) . Unit parameters and meters values are easily programmed using Gup10™ utility-programming software. (See the MTU150W™ Programming Guide) or by the FTU. 2. Meter Input: The meter input is a two wires cable. These wires connect to the meter output. Figure 1: MTU150W™ View Preparing for Operation Before installing the MTU150W™ on site, perform the following preparations: 1. Setting communication parameters 2. Self test Setting Communication Parameters

Installing the MTU150W There are two mounting methods: 1. Wall mounting 2. On-Pipe mounting Wall Mounting Installation 1. Fasten the mounting bracket on the wall with four screws (See figure 2) 2. Slide the MTU150W unit on the mounting bracket until the 4 clips are locking the unit 3. Define the parameters with the field programmer (FTU100) see the FTU User Guide 4. Insert the terminator to J9 (See figure 1) 5. Put the cover On-Pipe Mounting Installation 1. Fasten the mounting bracket on the pipe with two screws and the “Omega” bracket (See figure 3) 2. Slide the MTU150W unit on the mounting bracket until the 4 clips are locking the unit 3. Define the parameters with the field programmer (FTU100) see the FTU User Guide 4. Insert the terminator to J9 (See figure 1) 5. Put the cover Figure   : Wall Mounting Figure   : On-Pipe Mounting Restrictions: 1. Do not mount the unit on any kind of metal surface. 2. Do not mount any input cable next to the antenna (see figure). Meter types: 1.  There are two main types of meters: 2. Meters that produces a ‘Passive Pulse’. 3. Meters that produces an ‘Active- Pulse’ (known also as-‘’Pulse Generator’). Technical Specifications: Operating Voltage 8–15 VDC Standby Current 30μ A max. Tx Current 0.8A max. Power Output 2W Freq. Stability  2.5ppm at operating temp. range Operating Temp. -22  F  120  F (-30  C  60  C) Storage Temp. -40  F  158  F (-40  C  70  C) Weight 0.5 lb. (230 gr.) Wiring: 1. Connect the two polls of the Meter input cable to the meter using a self-stripping insulated connector (like 3M-Scotchlock or equivalent). 2. Polarity: if a ‘Passive Pulse’ type meter is connected, there is no polarity so the wires can be connected in any order, if an ‘Active Pulse’ type meter is connected, there is a polarity and the wires have to be connected in the following order: Red wire to the POSITIVE (+) poll and the Black wire to the NEGATIVE (-) poll, (see figure 4). The manufacturer is not responsible for any Radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user’s authority to operate the equipment. Figure 4: Wiring To maintain compliance with FCC’s RF exposure guidelines, this equipment should be installed and operated with minimum distance 20 cm. between the radiator and your body. Use only the supplied antenna.

MT150WP- Theory of operation and tuning procedures Rev: 0.1 MTU150WP Circuit description MTU150WP is a long-range synthesized radio alarm transmitter that is operated in UHF 450-470 MHz frequency band, and is intended for the operation into WAT-NETTM network. The MT150WP detects pulse on its inputs from water meters measuring devices and transmit it by one or four messages to WAT-NET TM monitoring center. When the number of the pulse is equal to the “Trans Scale” defined by the GUP10 utilities program or, else take place signal from internal timer or test button, the MTU150WP also transmit data to monitoring central station. The MTU150WP transmit data according to the WAT-NETTM data communications protocol. MTU150WP consists of a single electronic board mounting inside a plastic housing. The metal plate is used for the MTU150WP board and a plastic housing fastening. The MTU150WP board contains three major parts; - Synthesized RF, FM transmitter - Digital encoder, based on Intel 87C52 micro controller. - Analog voltage control block - Power supply and power switches. Theory of operation (Refer to the Circuit Diagram) The pulse from water meters measuring devices is follow through J11 input connector, passing trough U9 MC14017B decade counter and turn “ON” Q204 switch .The R125, C102 RC section is discharged to ground and Q21 switch pass VBAT voltage to VT+ track. The VT+ voltage activates U6, U7 and U5 power supplies. VCC voltage powering the U3 micro-controller. The micro-controller is initialize Tx mode and encodes the input data in FSK tones for the transmitter. When a transmission is initiated, a repetitive word block is prepared by the micro - controller for transmission. When PTT1 line is pulsed too low, the micro-controller sends the programmed frequency to the synthesizer and allows it to build up the carrier frequency. Subsequently the PTT2 line is also pulled too low and the amplifier link raises the RF signal from synthesizer to a power of minimum 2 watt. The Tx data is then activated and allow for the audio data to modulate RF signal. The micro-controller checks automatically the battery voltage before and during each transmission. If the battery voltage is lower than 10.5volts, a low battery message is transmitted and, if is lower than 8.5 volts, transmission is stopped. THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE CAUSED BY UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. SUCH MODIFICATIONS COULD VOID THE USER’S AUTHORITY TO OPERATE THE EQUIPMENT. KP Electronic Systems, Ltd. MT150WP- Theory of operation and tuning procedures Rev: 0.1 MTU 150WP has a self–test button, allowing the user, to test the proper operation of all circuits. As soon as it is pressed, the self-test LED 2 flashes: - Once System OK - Three times Battery fault (voltage lower than 8.5volts) - Four times Unlock frequency - Six times Low battery (voltage lower than 10.5volts) When the Q21 gate voltage will rise up to pinch-off voltage, the Q21 transistor switching off the transmitter circuits, micro-controller and in this case the sleep mode take place. The U11 timer is intend for the periodic timer diagnostic mode. RF Transmitter The transmit frequency is built around Fujitsu PLL MMB1501 chip U4.It uses 12.8MHz for reference frequency oscillator and 6.25KHz for step frequency. The loop filter is a low pass filter that attenuates noise and rejects the loop reference frequency. The loop filter consists of R60, R56, R53 and C40, C47, C41 passive elements. The voltage across C41 is the steering line voltage, which controls the VCO frequency. VCO consists of a BJT oscillator Q2 whose frequency is determined by D8 and L3. As the steering line varies over the range of 0.5V to 4.5V DC, the capacitance of the varactor D8 decreases as voltage is raised, causing the oscillator frequency to increase. Transistor Q9 is the buffer amplifier and raises the RF output of the VCO to the level required by the RF power amplifier. The 2 watts UHF power amplifier cover the range of 450-470 MHz. It consists of three stages. The firs stage, Q8 is Class ”A” and has a gain of 15db and delivers 100mw of output power. The second stage, Q7, is operated in Class “A” and has 9db of gain. Its output level is 0.8 watt. The three stages, Q10 a Class “C” RF final power amplifier .It can output 2 watts. The harmonic filter is an Elliptic low-pass filter with a 3db frequency of approximately 640MHz, and less than 1db insertion loss in the pass-band. The PTT1 switch consists of Q12, supplying the synthesizer and VCO 5volts DC. The PTT2 switch supplies the amplifier bias of 5 volts DC also supplies output power amplifier VBT voltage. Digital Encoder The digital encoder is based an Intel 87C52 micro-controller. It scans its inputs P0.4.... P0.7 The battery voltage check is made trough P1.6.
