IRRInet SYSTEM GENERAL DESCRIPTION

INTRODUCTIONMotorola’s IRRInet Control Center (ICC) is a computer-driven central management andcontrol system for water and irrigation systems.• Turf/landscape applications include irrigation systems for City and County Parksdepartments, highway and street median landscapes, Corporate Office Parks, and collegecampuses and school districts.• Golf course applications of the IRRInet are found in both private country clubs as well asmunicipal courses.• Agricultural applications of the IRRInet include drip and sprinkler irrigation systems, waterdistribution systems, and nursery and greenhouse operations.The IRRInet system operates in a “distributed” fashion - the field units perform the real-timeprocess, the central computer serves the functions of:• Programs archive• Alarm reporting• Closed Loop Response• Automatic Download of Programs/Instructions• Optional Paging in response to alarms• Optional DTMF remote control interface• Optional Weather station interrogation

IRRInet Field Satellite UnitsIRRInet provides a common solution to many different irrigation control and monitorrequirements, utilizing a modular concept to derive the various input/output (I/O)characteristics.Common to all models, the IRRInet basic model consists of a motherboard mountedunderneath a rack or chassis with slots. Each slot accepts a module, with 4 total slots. Thefirst slot is always taken up by the IRRInet Super CPU, providing the local programming logicto drive the I/O’s as well as supporting the various radio and line communication options.Note that a 6 slot chassis option is available through Motorola Service Providers thatprovides 5 slots for I/O modules.

Software capacity for inputs and outputs (I/O’s) is available in two options:• AG software — (included with basic IRRInet field unit) 126 inputs/250 outputs, 99 mainlines and 99 program lines.• TURF software — (option V418 added to any basic IRRInet field unit) 126 inputs/200outputs, 40 main lines and 200 program lines.The IRRInet may be configured for 115 VAC main power, the standard base model, oroptions may be added to change to 230 VAC or 12 VDC (battery/solar operation).

2

Depending on the specific I/O requirements, the remaining three module slots may beloaded with any one of the following, in any combination:

• IRRInet AC I/O Module -switching 24 VAC to independently wired field valvesolenoids and/or relays. Each module provides 16 outputs and 4 digital (dry contact)inputs.• IRRInet-SC I/O Module -provides an interface via a 2-wire cable to Motorola’sPiccolo RTU’s (remote terminal unit), supporting up to 63 RTU’s per module, for atotal of 63 outputs and 126 inputs per SC module.• IRRInet-DC I/O Module -intended for use with 2-wire 24 VDC latching solenoids,each module provides 16 outputs and 4 digital (dry contact) inputs.• MOSCAD 16 DI Module -provides 16 digital inputs.

Scorpio-V2, -AC and -DCWhere the location of inputs and/or outputs should be consolidated into one IRRInet, butissues of long wire runs and hardscape obstacles prevent this, the “reach” of the IRRInetmay be extended with the Motorola Scorpio-V2 product. Like another I/O module, Scorpio-V2provides both outputs and inputs that are logically monitored/controlled by an IRRInet—the difference is that instead of plugging into the rack, Scorpio-V2 is connected by radio,sending and receiving the information by way of either VHF or UHF radios.

Scorpio-V2-AC provides 24 VAC control outputs for either 8 stations with 2 digital inputs, or16 stations with 4 digital (dry contact) inputs, powered by 115 VAC (option for 230 VAC).Scorpio-V2-DC provides 24 VDC latching control outputs for either 8 stations with 2 digitalinputs, or 16 stations with 4 digital (dry contact) inputs, powered by an external source of 12VDC. Typically, this external source will consist of a photovoltaic (solar) panel,charger/regulator, and 12 VDC storage battery.

Scorpio-V2 supports a shared-radio configuration, where one unit without radio isconnected to a unit with radio — providing a maximumconfiguration of 32 outputs and 8 inputscontrolled/reported through the one Scorpio-V2 with radio.

Scorpio-V2 may be specified and installed as a unit withoutradio, allowing new systems to start off with the featuresand benefits of computerized irrigation control andautomation at the local level. At a later date the hardwaremay be upgraded to provide IRRInet-controland eventually implement a central control stationcomplete with personal computer.

Note: Scorpio-V2 does not include the keyboard/terminalfor programming, order separately.

IMPACTIMPACT is Motorola’s wireless valve actuator. This deviceprovides a command-only receiver packaged with theMotorola magna-latch 2-wire solenoid and is connected tothe irrigation valve by hydraulic tubing (normally open ornormally closed valves are supported). Operating off threeAA alkaline batteries, the IMPACT receives on/offcommands from a nearby IRRInet field unit, utilizing eitherVHF or UHF radio (same as Scorpio-V2).

Note: IMPACT requires a host-IRRInet equipped withradio to drive the commands (on/off). These units areintended to be installed above ground.

Inputs, ExamplesAll field units (IRRInet, Scorpio) have the capability of reading dry contact closures fromsensors. Typical applications include:• rain switch• pressure switch• pressure differential switch• flow meter pulse• level switch• wind speed switch• temperature (high or low) switch (thermostat)• soil moisture switch• intrusion or door switch• photocell switch

All inputs should be specified with the following specifications:• Dry contact or open collector• <3K W (Ohms) = contact closed• >100K W = contact open• Detection time• >100 milliseconds• 5 cycles / second or 300 cycles / minute maximum (For Piccolo RTU’s, maximum is 15 perminute)

Scorpio-V2 has a limited standalone capability when using sensor inputs:• 1 water meter input &1 fertilizer meter input• 1 pressure differential input for filter flush automation• 1 wait input

IRRInet supports a high level of flexibility - depending on the sensor, programs may be setup to respond by Starting, Waiting, or Stopping in response to C.O.S. (change of state) of thecontact. Multiple inputs may be linked together (600 series or 900 series conditions) andcombinations of “real” inputs (sensors listed above) and software “flags” (600 and 900conditions) used to create complex solutions to complex system requirements.

5

Note: Note that 900 series conditions require central computer access to the IRRInet fieldunit, these are not accessible from the keyboard/terminal in the field.

EnclosuresThe IRRInet field units may be ordered with an optional plastic NEMA-4X enclosure, or in therack mount configuration, to be mounted indoors on the wall or in another manufacturer’senclosure.The Scorpio-V2 is shipped as an indoor mount controller enclosure and also requires aNEMA approved cabinet for outdoor applications (wall mount NEMA-4X option available fromMotorola).The IMPACT is rated for above ground installation, not to be submerged under water.

ICC (IRRInet Control Center) SoftwareThe ICC software serves the purpose of a “network manager”. The “network” consists of anumber of IRRInet field units (includes the legacy MIR5000-f AC powered units) capable ofcommunication with the “server” - the ICC.

In concept, this is comparable to a “LAN” (local area network) that utilizes “smart workstations”. The work stations in this case are the IRRInet field units, providing localprocessing and input/output functions. The “host” is the personal computer with MotorolaIRRInet ICC with the appropriate radio and/or wireline communications hardware.The following features are available in the central system (software release version 10.0):

• Year 2000 compliantAssures continued operation after December 31, 1999.

• Operates on your choice of these operating systems: Windows’95, Windows’98, or Windows NT.Select the operating system with which you are familiar.

• Support for more than one project per central— you can open different central files that allowyou to run more than one FIU.Technicians can carry their customers' databases on their computer and switch projects as needed toassist in training and troubleshooting. System administrators with more than one FIU based systemcan switch between systems (including over a Local Area Network connection) as they superviseoperations.

• Software requires a unique “Key” to register – Software may be freely distributed fordemonstration and training purposes. When it is to be connected to an FIU contact Motorola fora unique registration key. This will ensure that Motorola maintains an accurate end userdatabase.Improved support to the end user.

• Five password levels with unique log-on names for every user allows you to track who did whatwhen.Improved accountability means better control of your system. Different users can be restricted tocertain "areas" (groupings of field units) and denied access to all others.

• True Windows user interface— the access to various functions is “flat”, no more nested menus tocrawl through trying to find the right item to run. Right-click mouse actions supported.You probably already know how to use various Windows programs. ICC provides a consistentinterface that utilizes many of the Windows standards allowing you to easily learn how to use thesoftware system.

• One screen shows you everything at a glance— the graphic map, the events log and the outline ofhow your system is organized (like Windows “explore” function) grouping field units into areas,areas into the system."One picture is worth a thousand words." Presentation of information in a clear manner saves youtime on the job.

• If you are working in another Windows application (e.g., writing a memo in Word) alarm eventswill force a pop-up screen to notify you of a new event.ICC continues to work in the background as you perform operations with other Windows softwareproducts. You don't miss important events coming to the ICC and you don't have to keep switchingback to ICC to check up on your system, the pop-up takes care of business for you.

• Export function of any report supported to allow sharing of information with other MicrosoftExcel software (e.g., export the water accumulation record).Manipulate the basic data, adding costs per unit, drawing graphs, etc.

• NETWORKING: Client-Server installations are supported allowing you to run your system overa network— any NOS (network operating system) that Windows supports.This means you can set the FIU up connected to a personal computer that is located on one node of anetwork and use other personal computers located at other nodes to view the activities and makechanges (all password access controlled). The system adapts to your management structure; you don'thave to modify your organization to fit the software system. Future support for communicating acrossthe Internet (TCP/IP protocol) will be available in IRRInet-XL.

• Interrogation of individual “points” (i.e., down to the individual input or output) streamlines thecommunication load on the radio or wireline channel to the field units. You can even have adifferent interrogation frequency when the object (field unit, area, single output etc.) is displayedon the graphic window (this allows more frequent update of the information when it is on-screen).Customize the frequency of data updates to match your requirements.

• Switch language on-line supported, including help files. One user may be more comfortableusing English, the next person may prefer Spanish— simple to switch, no reloading software.Adapts to each user's needs.

• Using the Windows “Print Manager”, all printers that are Windows compatible may be usedwith the ICC system.Your system stays current with technology-- just load the new printer driver into Windows!

• Every table allows a report to be printed.You don't use "print screen"; instead, you generate a report that can be printed. Making hard copy ofyour data entries is convenient and provides a good backup.

• You can build the system definitions either from “scratch” at the keyboard of the computer oryou can use the Upload Wizard to pull the data in from field units that have already beenprogrammed.Converting older MIR5000C systems is easy using the wizard, just upload the data out of the fieldunits. Saves time. Adding a new field unit? You can program it in the field and upload, or create theprograms and definitions in the central and download--your choice.

• Graphic maps may either be "fixed" or "user" created.Start with the fixed mode, where each field unit's main lines and valves are displayed schematicallyand develop your own "user" maps as time allows. You can switch back and forth while online withthe software.

7

• When creating your own maps, you have the ability to:♦ Create screens, import graphic files (bitmap, jpeg, etc.),♦ place navigation buttons on a screen (zoom to another screen function),♦ place inputs or outputs on top of the map (show the valves and sensors, all or selected ones),♦ place icons representing Areas and Field Units on top of the map♦ create and edit label fields on top of the mapPowerful "user" graphic tools help you easily customize the ICC software to your unique systemdesign.

• ICC supports the MIR5000f-AC field units (first released in 1985), the IRRInet field units, andthe upcoming new generation field unit, IRRInet-XL.Backward compatibility ensures you get the most from the investment you made in Motorola fieldunits.

• Closed loop conditions are supported by ICC.Powerful IF-THEN conditions provide automated control of your system in easy to understand format.

• New, an astronomical clock is added to the central "closed loop conditions" that supportsconditions based on sunrise/sunset.For example, you can set up a condition that turns the lights on 30 minutes before sunset, and off 30minutes after sunrise. The system has knowledge of your location's latitude and longitude, whichallows it to calculate the sunrise/sunset time every day.

• Event messages may be customized by the user and new events defined that relate to the system.Events form the foundation of a reporting system that is used to notify you of system failures alarmsand other situations that you may define as critical and "need to know". Express the information inyour own words so it makes the most sense. Information knowledge is your edge in watermanagement!

• Message paging is supported, sending alphanumeric messages to your pager.Messages are automatically generated from the Events list or you may send a user-written message toany user carrying an alphanumeric pager. You can leave the office but not leave behind currentknowledge of how your system is running.

• 2-way hand held remote control will operate via the telephone modem in the personal computer.You will use any device that allows you “call” the central (PCS, iDEN or analog cellular handset,interconnect on your two-way portable radio, pay telephone, whatever). Voice prompting fromthe central computer will lead you through the operation, including a security password.Take control of your system with you in the field. The central talks you through the operation!

• 1-way hand held remote control (as option to 2-way mode mentioned above) allows you to useyour existing radio communications system to send in one-way commands.Allows you to use existing radio technologies with the freedom to graduate to the two-way option at alater date.

• Flow Prediction may be used to analyze the demand on the hydraulic design.Analysis of the hydraulic demand can help you better balance the programs, smooth out the flowcurve, and improve energy efficiencies when using pumps.

8

• Enhanced graph plotting utilities are included in ICC.Consistent with the idea of clear and concise graphic presentation of system information, ICC has avery powerful graph generation "engine". You may perform calculations on up to three inputs toderive a single graph plot (e.g., sum 3 different water meters to draw a single flow curve over time).You may also choose to overlay multiple data sources onto the same graph plot (e.g., overlay flow andpressure on the same plot).

• Network Protection is provided in ICC.Water distribution networks may be defined to allow comparison of flow rates coming from "IN"meters and "OUT" meters. Theoretically, if the sum of the "IN" meters' flows is greater than the sumof all "OUT" meters' flows there is a leak somewhere in the system. Network Protection allows you todefine at what point an alarm is generated and may further be linked to a shut down of the entiresystem. This protects against catastrophic failures in the distribution pipelines.

• Sensor Measurements may be taken by ICC.Interface any transducer to the field unit, converting the transducer output to a pulse rate input. TheICC software provides either a linear or non-linear conversion of the raw pulse rate input to user-defined engineering units (e.g., if you are measuring pressure the ICC displays "PSI" or "atmosphere"(metric) units and the actual numeric value matches the gauge reading in the field).

• ICC provides comprehensive Irrigation Programming screens, including simultaneous display oftime to run, quantity to run and irrigation depth (inches or millimeters of water to apply).Managing your water in time, quantity or depth of irrigation is available--change one parameter andthe other two recalculate to show the effects of your changes.

• Define multiple crop types in ICC and adjust water factor percentage to each type.This reaches across field unit boundaries, attaching to the main line of any field unit. Use this toprioritize different main lines according to your needs. High priority may receive more water thanLow priority areas. Tag each main line ahead of time with the "High" or "Low" type, then modify thewater factor adjustment through the season by simply changing two factors. The changes arebroadcast to the field units and they respond according to the previously defined type tagged to eachmainline.

• Offline programming for field units provides a backup of the data in the field.You can create multiple variations of programs for each field unit at the PC and download any one ondemand or through the Closed Loop Condition table (IF date=4-July THEN send program #1 tounit#1).

IRRInet FIELD UNIT DESIGN GUIDELINESThe IRRInet field unit may be composed of any of the four available input/output (I/O)modules. Each module is discussed with respect to the irrigation design parameters uniqueto each type of output.The basic IRRInet model consists of the Super CPU, with one on-board port for radiocommunications, one port for the keyboard/terminal used for local programming, and oneAC Mixed I/O module. Model numbers and options provide for additional modules or thesubstitution of either the Single Cable or DC module for the AC Mixed I/O that comesstandard. These model numbers are summarized at the end of this section.

16-DI Digital Input ModuleThe 16 Digital Input module is not described; this module may be used where a higherdensity of inputs is required at the IRRInet. This module is actually from Motorola’sMOSCAD family and is cross compatible to the IRRInet platform. Specify this by the modelnumber FRN1420 for each 16 Digital Input module. Note that the 2 high speed counters onthe module are not used in the IRRInet application (these are in addition to the 16 DI’s).

AC Mixed I/O Module DesignThe following guidelines will assist the designer in specifying the correct field unitconfiguration.• 1. Count up total number of valves, filters, pumps, fertilizer injectors, and othermiscellaneous controls.• 2. Count up total number ofsensors that will be used.• 3. Count up total number of mainlines that will be used.• 4. Determine whethercommunication link to central iswire line or radio.• 5. Determine the requiredinstallation of the hardwarestandard pedestal or wall mountindoors or inside a NEMA typeenclosure.• 6. Provide a stable source of 115VAC (+- 10%) single phase power,Note: use additional line surge suppression toprotect against power line spikes.

Table 1, Voltage Drop Reference for AC circuits

Note: It is advisable to design multiple commons (AC neutral or return) for the valvestations to cut down on voltage drop where more than one valve will be operated at onetime.

Note: A rule of thumb is to run a common that is one wire size larger than the controlconductor (the switched "hot" to each solenoid) for each block of 12 valves, and provideseparate commons for the master valve/pump start command and any sensors.

For example: if you have designed an IRRInet field unit with 22 field valves, a master valveor pump start, and various sensors, you would first need to determine the wire sizing for thefield valves. In this example, let’s use a #14-1 UF for the control conductors. Following therule above, the neutral conductors (commons) will be one size larger, a #12-1 UF wire, andfour will be required 2 for the field valves (split the valves into two different groups), 1 forthe master valve and/or pump start relay and 1 for the sensors. The neutral conductors aretypically color coded white, and the control conductors one or more colors other than white.

Note: Installers should be directed to use crimp-on spade lugs for the connection of theneutral (AC-common) conductors to the power supply terminal strip.

12

Note: Also, the control conductors may be directly wired to the outputs terminal of theIRRInet field unit where the wire does not exceed #16 gauge (do not use spade lugs). Inmost cases, the field wires should be connected to an external terminal strip, and smallergauge (#16 or smaller) wires run up to the modules I/O connection terminals.4SensorsSensor inputs are connected like the valve solenoids provide a separate control conductorfor each sensor and a common neutral return.Note: All sensors must generate a dry contact closure, minimum 100 millisecond closed,frequency not to exceed 300 pulses per minute (if using Piccolo RTU on Single Cablemodule, reduce frequency to 4 per minute).Essentially, the IRRInet field unit is measuring the resistance in the sensor circuit, drivingapproximately 32 volts DC , detecting open or closed circuit. Typically, a #14-1 UF controlwire is sufficient, with a common #14-1 or #12-1 UF neutral return. Circuit resistance shouldbe kept under 3,000 Ohms in the closed contact mode.Note: The connection of inputs does not subtract from the control capacity of the fieldunit.AC Mixed I/O Module CapacityThis module consists of 16 solid state relay outputs, each rated at 0.7 amps at 24 volts AC,and 4 digital inputs for sensors. (In this example, we would need not only the 16 outputs onthe AC Mixed I/O module included with the basic IRRInet, but also another AC Mixed I/Omodule, for a total of 32 output stations and 8 inputs.)Surge And Lightening Protection For Inputs And OutputsThe IRRInet field unit inputs and outputs are protected against surges and spikes withinternal components that require adequate grounding provisions. Where lightening-inducedspikes and surges are prevalent, individual fusing of the output control conductors may beadvisable.

GroundingNote: Local grounding is required for the IRRInet field unit. Motorola’swarranty will be void if the resistance (as measured with a ground rod test set) exceeds 10Ohms.This provides a shunt path for surges and spikes in the primary and secondary lines/loads.Typically, a 5/8" x 8 copper clad grounding rod is driven into a nearby irrigated area, and a#10 bare copper wire is used to connect the ground rod (specify with acorn-clamp) to thefield unit protective grounding circuit. The resistance of the ground to controller should notexceed 10 ohms. In sandy coarse soils that drain rapidly, it may be necessary to burymultiple grounding rods or use a coil of #10 bare copper wire buried.

The 115 VAC line supply to the IRRInet field unit will typically have hot, neutral and groundconductors. Local electrical code usually requires that the service ground wire be bondedto the controller enclosure. This in no way relieves the installer of the ground rodrequirement; instead, the grounding rod must be installed to provide the less than 10 Ohmsresistance path to ground, and the wire used to bond to the controller cabinet should be onthe same lug as the incoming service ground connection.

13

HIGH VOLTAGE OR LINE SUPPLYThe 115 VAC line supply should be sized to provide capacity for the maximum current loadenvisioned.Note: 115 VAC single phase surge suppressers are available (Northern Technologies isrecommended) where a field unit is operating pump starters, and in areas prone toexcessive lightening or other sources of electrical supply spikes.

• Maximum load calculation for power line supply is as follows:1) IRRInet unit, stand alone, no radio = 1.0 amps at 115 VAC or2) IRRInet unit, with single high power radio (trunked/UHF/VHF/800) = 2.4 amps at 115VAC or3) IRRInet unit, with high power and low power radios (1 ea.) = 3.0 amps at 115 VAC

IRRInet Field Unit-SC DESIGNThe design of a Single Cable (SC) System requires careful consideration of the relationbetween field valves, water sources and water meters, and choice between power supplies.

The IRRInet SC module can handle up to 63 RTUs. 61 of these RTUs may be used tocontrol valves, pumps, etc., and #62 and#63 are reserved for the working andalarm reporting functions, respectively. Itis possible to install 3 single cablemodules on the same IRRInetrack/chassis, for a total of 189 possibleRTUs driven by one IRRInet, using 3independent 2-wire cables, one for eachmodule.

The first step in designing a IRRInet SCsystem involves breaking the irrigationsystems into logical grouping of fieldvalves, their respective water sources(pump, city meter, etc.) and fertilizerpumps, so that the maximum of 63control RTUs is not exceeded. Anythingthat must be controlled in relation to theirrigation process will use one PiccoloRTU, including:

The second step is to lay out the system on paper. The Piccolo RTU comes with backindications two positions available for sensors (this means you can have 126 sensor backindications reporting in to the IRRInet field unit-SC module!). These positions are labeledBI-A and BI-B.

14

The water meter pulse is connected to BI-A of the RTU which operates the mastervalve/pump start. In the case where there is no master valve/pump start RTU, the watermeter pulse is connected to BI-A of the RTU which operates the last valve on the main line.

The fertilizer meter pulse is connected to BI-A of the RTU which operates the fertilizer start.

The Pressure Differential (PD) switch (used to automate filter flushing) is connected to BI-Bof the RTU which operates the master valve/pump start. In the case where there is nomaster valve/pump start, the PD switch is connected to BI-B of the RTU which operates thelast valve on the main line.

Third, with the RTUs located in the field, now determine the shortest cable run between theIRRInet field unit-SC and the RTUs. The RTUs connect to the cable in series, and the #14-2 UF cable can be up to 6 miles in total length (a #12-2 UF cable can be used for up to 8miles total length).

Fourth, with the cable routed, determine the number of communication line surge protectors(FLN2169A) that will be required for the RTUs. Where one or more RTUs are located,branch off the cable and connect the surge protector, then the first RTU at that location.Also, at the IRRInet field unit-SC, specify one FLN2169A line surge protector.

Fifth, determine the power supply. You may select either a conventional 115 VAC powersupply unit, or the optional 12 VDC configuration (typically requires a solar panel andregulator to charge a battery).Note: A separate grounding rod system is required in addition to the electrical serviceground in order to provide a less-than-10 Ohms resistance path to earth-ground.Amperage (current) requirements at 115 VAC = 2.5 amps. This is worst case, assumingboth radios are employed (e.g., trunked and low power UHF).A stand alone IRRInet-SC unit will draw 0.2 amps at 115 VAC without any radios.

12 VDC / SOLAR DESIGN CONSIDERATIONSWhere the option of 12 VDC option will be used, add the option V274 to the basic IRRInetunit. The size of the battery should be calculated by the number of dark days that will beexpected multiplied by the daily power consumption (12 amp-hours/day) plus 25% batteryreserve (The 25% battery reserve will provide power to radio communication links whereused).

If a gel-cell type battery is used, check with the manufacturer on the allowed depletion(usually in the range of 10-20% of capacity) and size the battery accordingly. The solarpanel, which must include a 12 volt DC regulator, is sized based on the daily number ofhours of sunlight (average 10 hr.) divided into the number of dark days watts (multiply daysx 144). Contact a local supplier of solar panels for assistance in specifying the appropriatemodel.

Note that where signal conditioners are used on sensors (e.g., Data Industrial Flow MeterLARC relay) the 12 VDC power for this conditioner must be connected to the same supplyas the IRRInet field unit to prevent damage to the equipment.

The final step is to locate the IRRInet field unit. Take into consideration availability of power,proximity to the pump station or water source (a logical location for the controller) and radiopath coverage, where a radio communication link to a central computer will be used. It doesnot matter where on the run of the two-wire RTU cable the IRRInet field unit is located.

15

IRRInet Field Unit-DC DESIGNThe IRRInet DC provides local two-wirecontrol of 24 volt DC magna-latchdevices, including theMotorola magna-latch solenoid, theIrritrol IBOQ solenoids, and24 VDC latch relays (available fromothers).

Each IRRInet DC I/O moduleincludes 16 outputs and 4 digitalinputs; up to three DC I/O modulesmay be installed in one IRRInetrack/chassis, for a total capacity,locally, of 48 DC latching valvesolenoids and 12 sensor digitalinputs.

Figure 7. IRRInet DC Mixed I/O Module18Locally wired inputs from sensors provide these and other functions:• Water meter• Fertilizer meter• PD switch (pressure differential for filter flush automation)• Any other dry contact from a sensorNote: Each group of 4 outputs has its own common. Installers should be careful not tomix commons from other output groups.The first step in designing an IRRInet DC system is to take inventory of the total number ofcontrols that will be needed, laid out on a map of the system. These would include:• field valves• master valve and/or booster pump start• fertilizer start (may be a valve or a relay)• reservoir pump start• filter back-wash valves• different fertilizer solution tank valvesUsing Motorola’s 2- wire latch solenoid valveMotorola can provide a 2-wire solenoid valve for controlling hydraulically operated valves(where tubes are routed from the field valves back to the controller location). In the locationof the field unit, consider the limitation of 20" or 1/2 meter maximum distance between theIRRInet DC’s outputs and the magna-latch solenoid. This means that the control ofhydraulic field valves will require running 1/4" tubes back from each valve to the magna-latchsolenoid.Typically, the IRRInet field unit-DC is located at a pump station or at the head of the watersource. Where elevation changes are encountered between the field valves and theIRRInet field unit-DC, beware of down-hill runs of tubing from the IRRInet field unit-DC thismay require the installation of a reversing hydraulic actuator.Using Existing DC-Latch Solenoid ValvesThe output characteristics of the IRRInet DC I/O module match the requirements of thelatching solenoid valve available from the IBOQ line of irrigation valves. In this case, directburial wires are routed from the valve back to the IRRInet unit. In most cases, if existingIBOQ valves are installed and operating satisfactorily, the IRRInet DC I/O module willlikewise work fine.

16

19Note: For new designs, please follow these specifications regarding wire distance runsand gauges:#14-1 UF wire, 1,000 feet from controller to valve#12-1 UF wire, 1,200 feet from controller to valveFinally, determine the power supply. The IRRInet field unit-DC is designed to operate on 12VDC regulated power. The power supply is typically a deep cycle battery which may beoptionally trickle charged by a solar panel. Please refer to the IRRInet field unit-SCinstructions regarding 12 VDC/solar panel configurations.

Virtual Main Line OperationsMotorola has included the feature of Virtual Main Line in the IRRInet software. A main lineis defined as a water source, with one input (pump, point of connection to the city main,etc.) and then a number of outlets (valves) off this main line.A Virtual Main Line is defined as a water source with more than one input, and the optionfor one or more outlets (distributing water to other main lines, not lateral valves) as well asa number of outlets that draw their water from this Virtual Main Line.Note: IRRInet supports up to 10 virtual water meters per IRRInet field unit, maximum.Note: The use of Virtual Main Line, in a Quantity Based Mode, requires that all flow meterinputs be connected directly to the IRRInet unit, and not to Scorpio-V2 units.Note: When meters are connected to Scorpios, only Time + Flow is allowed for the virtualmain line’s irrigation mode.Note that the traditional main line concept, a single flow meter serving water to a singlemain line with valves is available on both the IRRInet and Scorpio-V2 units with respect towhere the flow meter is connected. It is only when the flow meter must contribute to thecalculation of a Virtual flow that this restriction applies. In other words, you can define astraight main line, where the flow meter is physically connected to a Scorpio-V2 unit, andeverything will work fine.20

Scorpio-V2 DesignScorpio-V2 field units may be configured for either AC power (115 VAC standard, 230 VACoption) or DC power (using 12 VDC source).Note: The Scorpio-V2 operating in the stand alone mode provides 16 program lines forindependent valve programming - do not include main valve/pump start, filters, and fertilizerpump in this count.Note: When used as a radio remote unit, the Scorpio-V2 units must be located within therange (radio) of the host IRRInet field unit. Range and coverage information is always sitespecific and must be verified by qualified Motorola personnel prior to design andconstruction. There are no rules of thumb that are safe, this must be engineered up front.Contact your Motorola representative for assistance in proper design.Note: Also, the use of Scorpio-V2 units requires an FCC (Federal CommunicationsCommission) radio license prior to the operation of the system. Again, contact yourMotorola representative for assistance.The implementation of the Scorpio-V2 units comes into play where low density" control andmonitor functions are needed. The capacity of Scorpio-V2 (basic configuration is 8outputs/2 inputs, expandable to 16 outputs/4 inputs) is ideal for retrofitting of smaller timeclocks and for integration of other control and monitor functions on a typical irrigated site(for example, control the tennis court lights, a remote pump, read an intrusion sensor on alocked door, etc.).

17

Because the Scorpio-V2 incorporates a two-way FM radio, data is both received from andtransmitted to the IRRInet field unit. This means that the real-time process of executingprogrammed instructions and evaluating sensor readings (and taking appropriate actionswhen necessary) is driven by the IRRInet field unit. The Scorpio-V2 unit has the ability toreceive a command (turn something on), acknowledge receipt of the command back to theIRRInet field unit, and further to report on either the status of an input or the violation of aprescribed flow window if monitoring a flow meter. This flow window is downloaded fromthe IRRInet field unit and is updated as each step of the program is executed to allow forvarying expected flows as different irrigation laterals activate.Note: The Scorpio-V2-AC has a maximum load capacity (for solenoid power) of 1.2 ampsat 24 volts AC, and each output should be limited to a maximum of 0.7 amps at 24 volts AC.Finally, no more than 4 outputs may be operated simultaneously on one Scorpio-V2 unit(AC and DC).

The connection of output and input wires should be designed to interface to a barrier terminalstrip. Each unit ships with a Molex cable connector (2 if the expansion board is installed) thatterminates with loose wires. These wires should be tied to each isolated point on the terminalblock, and the corresponding field wires brought to the other side of the terminal block.

Finally, depending on the radio-path requirements, an external antenna may be required.Note that each Scorpio-V2 unit ships with a Heliflex antenna (similar to the antenna on aportable radio or cellular telephone) as well as an adapter to BNC. The Heliflex antennashould only be used where the Scorpio-V2 is located in a radio-transparent building orenclosure (such as Fiberglas), in all other cases, use an external antenna connected viathe BNC adapter.

Site-specific parameters will determine the type of external antenna, typically either a domestyle disguised antenna on top of a metal enclosure or a directional Yagi mounted on apole. It is recommended that no more than 50 Scorpio-V2 units be designed and linked toone IRRInet field unit.Note: If more than 99 Scorpio-V2 units are to be designed into a single central system,please contact Motorola.For each Scorpio-V2, the installer should provide a table showing the inputs and outputsconnections, as well as the address number of the unit. A short description of each outputand input (e.g., output 1 irrigates hillside shrub bed, input 1 is flow meter pulse every 1gallon) so that the IRRInet field unit can be set up for the correct Physical Connections foreach output and input. Once the data regarding the location of the new outputs and inputsis entered in the IRRInet field unit, all programming is performed at this level.Note: The Scorpio-V2 supports the same keyboard/display unit as is used with theIRRInet field unit and must be ordered as an option to the basic unit.Scorpio-V2 (with Radio) AC Power RequirementsAC-Power Line sizing should be based on the maximum load of 2 amps at 115 VAC; lowvoltage wiring should be designed with the same considerations for wire size versus currentand distance, refer back to the section in this chapter regarding the IRRInet AC I/Omodules low voltage 24 VAC calculations.Scorpio-V2 (with Radio) DC Power CalculationsDC-power sizing and storage capacity should be based on the following 12 volt DCparameters: 30 milli-amps continuous, 1 amp during transmit (every valve command, on oroff, is acknowledged, as well as alarm reporting and response to interrogation for flow rates= transmit time each event is 10 seconds worst case).

22

18

[Example] Assume all 16 stations are used, operated for two cycles per day. [(16 stations) x(2 Open commands) x (2 Close commands) x (1 amp) x (10 seconds)] / [600 amp-seconds/amp-hr] + [.030 milliamp x 24 hours/day = 1.8 amp-hours/day at 12 Volts DCNote: When designing around the Scorpio-V2-DC, the maximum run from the controllerto the magna-latch solenoid valve should not exceed 1,000 feet on 14 gauge wire, 1,200feet on 12 gauge wire. Note that the latch output has been designed to fit manycommercially available 2-wire latching solenoids. Please check with your Motorola dealerfor the correct solenoid.Note: Scorpio-V2-DC units have a separate common for each group of 4 outputs. Besure to run separate commons for each group. Do not connect these commons to theprotective ground rod.

IMPACT DesignIMPACT is a wireless valve actuator, battery operated, providing hydraulic control of anyvalve.

1/8" tubing is used to connect the line pressure to the COMMON port, and routes to thevalve through the VALVE port, applying pressure to the top of the valve diaphragm. Uponopening, the COMMON port is shut, and the VALVE port is opened to EXHAUST, drainingthe water on top of the valve diaphragm.

3 x AA alkaline batteries must be installed at the start of every irrigation season.Note: IMPACT requires radio communications from a nearby IRRInet unit equipped witheither the UHF or VHF radio option, and the corresponding radio path study and FCClicensing requirements.An IMPACT is used to control one valve and uses one of the available valve assignmentsin the host IRRInet. This unit has no sensor input feedback mechanism to the IRRInet.Each IMPACT is pre-assigned a numeric address from the factory for ease of installation.Additionally, the IMPACT features an on-board self diagnostic test procedure that the enduser or installer may initiate. This will check functional parameters, including:• Low batteries, replace in 2 weeks• Very low batteries, replace now• Output short circuit (check wires & 2-wire solenoid)• General hardware failure (replace board)Note: The most important aspect when designing the IMPACT is to carefully documentand evaluate the radio path between the host IRRInet and each IMPACT. Qualifiedpersonnel, Motorola or distributor, should be retained. Impact is available in either VHF orUHF frequencies.

Power Consumption Statistics — Field Controllers @ 115 volts A.C.

For solar power designs, the duty cycle of the radios (three states, Transmit, Receive andIdle) must be taken into account. Motorola recommends a 10% transmit, 10% receive, 80%idle ratio for determining amp-hour consumption. The recommended 10-10-80 ratioprovides 144 minutes of transmission and 144 minutes of receive time per day.

IRRINET CENTRAL CONTROL (ICC) STATION

IRRInet FIUThe IRRInet Field Interface Unit (FIU) provides a communication interface between thestandard RS-232C serial data port from an IBM compatible personal computer and theMotorola Field Interface Unit (FIU).

The Motorola Data Protocol (MDLC) has been developed to assure the highest levels ofdata security and error correction, regardless of transmission over wire-line or radiomediums.

The design of an IRRInet central control station must include the FIU — there are differentmodels of the IRRInet FIU for the various communication mediums of line and radiosystems. Line Surge Protection (FLN2169A) is required for any wire-line communication.

The FIU configuration of the IRRInet provides a painted steel NEMA enclosure suitable forwall mounting near the personal computer and includes the following:• A 5 amp-hour Ni-Cad battery pack that supports radio communication in the event of alocal power failure• An extra slot available for local connection of an I/O module (does not include a 24 VACpower supply)• A cable to connect the Super CPU’s RS-232 port to the personal computer’s serial port.Note that this complete unit weighs approximately 40 pounds, and installation shouldprovide adequate anchoring to the wall (into the studs).

The installation of the FIU should be specified to include a Motorola Service Provider’sinvolvement to set up the FIU, connecting it to the end-user’s computer and to the wire-lineand/or base station radio.

Note: The IRRInet FIU supports both radio and wireline links to the other IRRInet or 5000f-ac units using Rad-2 port card which carries a line port in parallel. If this mode is required(radio and line) be sure to use Rad-2 port for the radio link to the field.

Note: The IRRInet ICC further supports two radio links, one for communication to otherIRRInets and MIR5000F units, the other for communication to Scorpio units in the nearbyarea of the central control location.

Aside from the communications interface between PC and the Motorola MDLC dataprotocol, the FIU serves these additional functions:

• Message Buffer — the FIU will log (receive) and acknowledge up to 49 in-bound eventreports from the field units (“contention”) and save these if the personal computer is off line.This is like an answering machine, assuring no messages are lost.• LED Display — the front panel of the Super CPU features a Light Emitting Diode displayfor diagnostic purposes.• Self Diagnostics — the FIU is a microprocessor based device with built in (EEPROM)software. When the FIU is “re-booted” (power off then back on) the FIU executes a self-diagnostic routine and then accepts a down- load from the computer for the specificcommunication mode chosen.

Central Options

Weather StationThis option requires two software modules: one to be ordered fromMotorola (to be included in a future release of the ICC software) and the other from AquaEngineering, Inc. (phone in the United States, 970-229-9668).Note: The Aqua Engineering, Inc. software module, “WEATHER_3", supports modemcommunication through the serial port multiplexer. Normally, the weather station(s) are setup on dial-up telephone drops.PagingThis option uses a software module included in the ICC software from Motorola, and mayrequire additional hardware if an on-site paging base station will be used. In most cases, thePaging software module will utilize a modem to call up a Radio Common Carrier (RCC) or in-house paging base station. Pagers may be supplied by the RCC, the in-house pagingadministrator, or ordered as additional hardware from Motorola.DTMF remote controlThis option uses a software module included in the ICC software from Motorola and mayrequire additional hardware.

Two-way DTMF--The Central "Talks" to You!1. This mode features voice prompted operation. You place a telephone call to the

central, the ICC software "answers" the phone and prompts you for password. Fromyour telephone, you use the number keypad to enter numeric codes as prompted bythe ICC software. If you have a voice + data modem installed, you will be able toselect which modem you will use for DTMF operation (remote control of the system).

One-way DTMF2. One-way DTMF is for inbound only tone commands, usually sent over a two-way

radio to the IRRInet FIU's base station radio. For one-way DTMF, select "QuietDTMF" and assign the appropriate Com port to which you have connected a modem.A junction block will need to be provided that allows you to connect the "handset" portof the modem (not the TELCO port) to the microphone port of the radio. The centertwo pins of the RJ-11 cable connecting to the modem should be connected to AudioReceive and Ground coming from the microphone port of the radio.

25

For one-way DTMF, a radio base station is required, even if the field unitcommunication medium is wire-line. The radio base station may be the same unitused for the field units’ link to the central; in large systems a separate base stationmay be installed to move the DTMF operations off the same channel as is used bythe FIU-to-field units link.

MIR5000C CENTRAL RADIO DESIGNThe system designer will need to determine the mode of communication between centraland field units.Once this is decided, the specification for the central is straight-forward — IRRInet FIU basicmodel must be on the same frequency (or sub-fleet) as the radios in the field units.The specifier should then determine installation requirements, with these parameters inmind:• Where will the base station radio be located — in which room, against which wall? Thiswill direct the Motorola Service Provider when it comes time to run the antenna lead.• What is the approximate length of run between the base station radio and the out-sideantenna location?• If this is a conventional system without a repeater, is the base station located in the middleof the coverage area, or at one end?• Will you be controlling Scorpio and IMPACT radio remote I/O’s from the FIU?

The installation should be specified to be performed by the local Motorola Service Provider,and include labor and materials to install the IRRInet ICC equipment. The specificationshould further direct the Motorola Service Provider to supply and install a grounding kit andlightening arrestor on the antenna lead.

MIR5000C CENTRAL COMPUTER WIRE-LINE DESIGNWhere the central computer will be communicating with part or all of the system via wire-line(includes dedicated telephone), there is only the requirement, mentioned previously, tospecify the #FLN2169A line surge protection device.

In a wire-line system, the designer should carefully instruct the installer regarding materialsand installation details.• The wire-line, where direct burial cable, shall meet or exceed the requirements of a #14-2UF cable, solid copper conductors.• Burial of cable shall be no less than 30" below finished grade.• Cable shall only be spliced in the field unit enclosure. Where splices between field unitsare necessary, an above-ground weather tight junction box shall be used.• Direct burial cable shall be tested, prior to the connection of the Motorola equipment, forresistance to ground (each leg) — the resistance to ground shall exceed 5 million (meg)ohms. Each section of cable shall be measured and the measured values verified by theinspector or owner’s representative, and a written report provided recording these values.

Note: Where the resistance of a given section of cable falls below the 5 meg-ohmsthreshold, this cable must be repaired or replaced prior to connection of the Motorolaequipment.• Each MIR5000f or IRRInet field unit shall be isolated from the wire-line by a Motorola#FLN2169A line surge protector.

While the above “warnings” may seem restrictive, be advised that experience with wire-linesystems have proven these as reasonable precautions that dramatically improve the lifeexpectancy of the buried cable.

26

Where a dedicated single circuit number telephone line link is used, please specify, to thetelephone company, that the data is transmitted (at the central and at the field unit) at 0 dBlevel, and the line signal loss shall not exceed 15 dB drop between the field unit drop and thecentral drop. The dedicated single circuit number telephone must terminate in a two-wireconfiguration, both at the central and the field units.

The IRRInet line communications adapter uses a 600 Ohm balanced two wire driver, aMotorola FSK-modem transmits data at -0- dB level with the frequency range of 900 to1500 Hz, half-duplex.
