Introduction Cabinet Options The BaseStation 3200 is available in three basic cabinets: C-series: 16 gauge steel powder-coat indoor/outdoor wall mount cabinet X-series: 16 gauge galvanized steel powder-coat (X) or 16 gauge stainless steel (XS) indoor/outdoor large wall mount cabinet P-series: 16 gauge stainless steel pedestal cabinet C-series X/XS-series P-series All cabinet dimensions are in inches (in).
Introduction How to Irrigate Efficiently This section covers some key concepts essential to better and more efficient irrigation. The BaseStation 3200 is specifically designed to help you irrigate more efficiently than any other commercial irrigation controller. The 3200 supports multiple smart watering strategies, including Historical ET, and smart watering with Soil Moisture Sensors.
Introduction Soil Moisture Content Soil scientists and Agronomists have been studying the plant-water-soil system for over 100 years. Early work in irrigation efficiency focused on the estimation of soil moisture based on weather information, plant water requirements, and soil information such as soil texture and slope. With the availability of inexpensive and highly accurate soil moisture sensors, we are able to take soil moisture based irrigation to a whole new level of efficiency and effectiveness.
Introduction Watering Strategies Each property is unique, and has unique watering requirements. In order to support a broad range of climate zones, plant types, landscape designs, and landscape usage requirements, the BaseStation 3200 supports a variety of watering strategies. The basic watering strategies supported by the 3200 are shown in the table below. Refer to the programming sections for details on how to configure your controller to use these strategies.
Introduction One important thing to remember about watering strategies: any one zone (or valve) can only be watered according to one strategy. In other words, you cannot configure a zone to be watered automatically using a soil moisture sensor and also be watered on a separate timed schedule. Zones can be linked together and watered as a group, regardless of the watering strategy selected. See below for more information on Schedule Groups.
Introduction one Schedule Group, and are controlled by a single soil moisture sensor in one of the infields. Likewise, all zones covering the outfields are grouped into a second Schedule Group controlled by a single moisture sensor in one of the outfields. Since all the soccer fields have similar plant types and sun exposures, all zones for all the soccer fields are grouped together and controlled from a single soil moisture sensor located in one of the fields.
Introduction As you can see from the tables above, most sprinkler heads have higher precipitation rates than most soils. Soak Cycling breaks the total run time into shorter water “cycles” with “soak” periods in between to allow time for water to soak into the soil. When the irrigation schedule puts down more water than the soil can take up, the excess water will typically run off to the lowest point, leaving some areas of the landscape, or even the entire irrigated landscape, under watered.
Introduction If you do get brown spots in your landscape, fixing distribution uniformity issues will give better long term results than increasing run times or moisture settings. Every irrigation controller must be programmed to water to the “driest spot” in each zone.
Chapter 1 – Getting Started 1 Getting Started Section Contents Installing the BaseStation 3200 .......................................................................................... 14 Installing Standard Accessories .......................................................................................... 17 Conventional Irrigation Wiring Installation......................................................................... 18 Two-wire Installation ......................................
Chapter 1 – Getting Started X/XS-series Wall Mount Cabinets The X and XS series Wall Mount cabinets are designed for outdoor or indoor wall or post mounting. The cabinet features a center located key-hole main mounting screw assembly for easy mounting, plus an additional center mounted hole as indicated in the diagram below. The X & XS cabinets feature a ¼” air gap between the chassis and the mounting surface – this reduces long term risk of water incursion or ice-dam buildup during inclement weather.
Chapter 1 – Getting Started P-series Pedestals Cabinets The P-series Pedestal units are designed to be pad-mounted, and come with a concrete template for locating all mounting bolts, AC power and two-wire and/or valve wire conduits.
Chapter 1 – Getting Started Installing Standard Accessories Rain Switches and other Normally Closed Sensing Devices All BaseStation 3200 controllers are compatible with industry standard Normally Closed (NC) sensing devices such as rain switches. These devices can be directly connected to the appropriate terminals on the 3200, or can be connected using Pause biCoders to the two-wire path.
Chapter 1 – Getting Started Normally Closed sensing devices should not be wired in series with either the valve common (on R-series units) or either side of the two-wire path. Wiring devices in this manner will defeat the wire health and solenoid current detection features built into the controller, and will generate incorrect messages and alerts.
Chapter 1 – Getting Started Connecting Valve Wires and Moisture Sensors over Valve Wires Baseline biSensors can be connected directly to the valve wires on the Sensor-over-valve-wire Ports (A1, A2, B1, B2) on any 12 or 24 zone connection module: Conventional Wiring Example with one biSensor: Baseline biSensor connected over valve wires. Note waterproof connectors Existing valve and common wires used.
Chapter 1 – Getting Started Two-wire Installation All BaseStation 3200 and 3200R controllers are equipped with a full-function two-wire port capable of connecting to field biCoders, powered retrofit biCoders, biSensors, flow meters, and other devices. Since Baseline’s two-wire features full bidirectional communications, you can connect all your irrigation accessories to the same two-wire path – saving time and money compared to conventional wiring.
Chapter 1 – Getting Started Serial Numbers for zones 1-24 in a BaseStation 3200R BaseStation 3200R systems are preconfigured at the factory to assign zones 1 to 48 (depending on how many zones the unit is equipped with) to terminals 1 through 48. However, by using the specific serial number, any terminal can be re-mapped to any zone address. Two-wire Connections and Layout Baseline uses a proprietary digital protocol to communicate over two-wire.
Chapter 1 – Getting Started Wire Lengths Total wire length supported depends on the gauge of the wire used. Straight Run Looped Run Wire Layout Straight line, star, looped and combination configurations are supported (see next page for diagrams). It is suggested that only one continuous loop be laid out around the site. This usually follows the main water lines. The loop will start at the BaseStation™ Controller, continue around the site and then return to the controller.
Chapter 1 – Getting Started Wire Burial Wire should be buried at a depth appropriate to protect the wire from mechanical damage due to digging or aeration. Baseline’s two-wire system operates under 30VAC RMS, which is considered safe for shallow burial as outlined in the National Electric Code. All installations should comply with local electrical codes. Field Decoder Wiring Baseline field biCoders are deisgned for direct burial and are tested to very rigorous standards of durability.
Chapter 1 – Getting Started For R-series controllers, a lightning arrestor and appropriate ground rod or plate are required for each moisture sensor connected to a valve wire that is more than 300’ from the controller. Connecting to BL-5200R Series Wall Mount biCoders Baseline 5200R series powered biCoders are specifically intended for retrofit applications, and make combining several old controllers into a single BaseStation 3200 easy and affordable.
Chapter 1 – Getting Started Total Supported Devices & Limits Listed below are the total numbers of devices by type that can be connected to a BaseStation 3200. The BaseStation 3200 can communicate with a maximum of 110 devices (device loads) on the two-wire path within the layout and length limits outlined later in this section.
Chapter 1 – Getting Started Installing biSensor Soil Moisture Sensors In order to locate a good place for a biSensor, you must first choose which zone or zones sensors should be installed in. To do this requires that zones be grouped into Schedule Groups. Only one zone in a Schedule Group will have a sensor, which will make it the Primary Zone. Within this Primary Zone, you can then choose a good location for the sensor.
Chapter 1 – Getting Started Dealing with Slopes and Berms Steep slopes and berms are possibly the most difficult landscape areas to irrigate efficiently. Runoff is the main issue, but there are also often subsurface drainage issues that can result in soaking wet low areas and bone dry high areas. Construction of berms often requires compaction of the central mass, which can also cause water movement and drainage issues.
Chapter 1 – Getting Started Turfgrass As stated above, the sensor should be buried 2” to 3” to the top of the blade, or in the top 1/3 of the root zone of the grass: Newly Seeded Turfgrass or New Sod The default watering strategies for the 3200 are intended to optimize water efficiency for established plants and turf. This style of watering can result in poor performance for newly seeded turf.
Chapter 1 – Getting Started Angling the sensor can profile a deeper soil column for trees that have deeper root structures as well. If the tree is watered with drip emitters or bubblers, install the sensor in a location that is not directly under the emitter or bubbler to avoid partial watering of the whole root zone of the tree.
Chapter 1 – Getting Started Searching for and Assigning Devices Before any biCoders or biSensors can be programmed in the controller, the controller must find that device and assign it as appropriate.
Chapter 1 – Getting Started Step 1: Search for biCoders Valve biCoder assignment is accomplished in the biCoder Menu dial position. Turn the dial to the biCoder Menu, then press ENTR to Search for biCoders. Like all menus on the 3200, you can look at the on-screen help for instructions. The Search may take several minutes to complete. You will see a status screen like the one shown here while the search is in progress. Press CLR to cancel a search in progress.
Chapter 1 – Getting Started Zone Status Note that the status of each zone is shown in the Zone Number list. The zone status codes are: OK – Working properly OP – Open circuit SC – Short circuit ER – Communication error Zone Numbers are Pre-Assigned in R-series All conventional wire versions (R-series) of the 3200 have been pre-assigned at the factory such that terminal 1 is assigned to zone 1, terminal 2 is assigned to zone 2, etc.
Chapter 1 – Getting Started Assigning biSensors to Primary Zones Refer to Section 2, Moisture Based Watering below for instructions to assign sensors to Primary Zones. Setting the Controller Date and Time To set or change the controller date and time, turn the dial to the Date/Time menu, then use the +/- and NEXT/PREV keys to set or change each field as desired.
Chapter 1 – Getting Started On-screen Reports Follow the on-screen instructions to access reports from the Main Screen. By using the NEXT/PREV keys, you can cycle through the report pages: Main Screen Program Reports Moisture Reports Flow Reports Messages Use the +/- keys while on any report page to see more reports or messages for each screen. Messages can include status or warning messages, or serious controller alarms.

Chapter 2 – Basic Programming Even within a group of zones there will be a need to have different run times. This is accomplished by changing the tracking ratio of the linked zone. When the water time tracking ratio of a likned zone is set to 75% of the primary, it will run for that percent of the run time of the primary zone (75% of one hour will be 45 minutes). Changing the run time for the primary zone will then get set for each linked zone, by their individual tracking ratio values.
Chapter 2 – Basic Programming minute increments from the top of the hour. If there is no start time, then the program is considered to be OFF or disabled and no watering will be allowed on the zones of that program. Start times are set from the Start Times dial position. To add a start time, highlight an empty start time and use the + or – keys to set the time. A start time can be cleared by pressing the CLR key.
Chapter 2 – Basic Programming yes on a day will allow a start time to start the program. A program that is started on one day will continue to run until it completes, even if it needs to continue to the next day, even if the next day is not a water day – this means starting a six hour program at 10 PM on Monday will finish up at 4 AM on Tuesday, even if Tuesday is not a yes day..
Chapter 2 – Basic Programming Micro-Climates and Zone Scheduling Groups Your site is composed of multiple areas that can be thought of as having similar watering needs (the zones of the softball field have a different set of watering needs than the north lawn between the sidewalk and the building). These areas can be thought of as micro-climates.
Chapter 2 – Basic Programming Soak-cycles must be used with biSensors – besides allowing the applied water to soak into the soil, soak-cycles allow time for the water to reach the biSensor depth so the biSensor can be used to control the water cycle. Lower Limit This water strategy provides an excellent way to achieve healthy, deep-rooted grass. The lower limit may be either set manually, or the limit may be calculated by having the controller perform a calibration cycle.
Chapter 2 – Basic Programming Upper Limit This water strategy also has several programming options. As previously mentioned, this strategy will vary the zone water time each time the program runs, to apply enough water to raise the moisture level to field capacity. Soak cycles are critical for this mode as the controller will monitor the moisture level as water is applied. At the end of each soak cycle it will determine if an additional water cycle is needed.
Chapter 2 – Basic Programming Program start time Valid water day If a moisture biSensor is used, then the moisture level at the program start time is less than the limit There isn’t an event day There isn’t a rain sensor stop condition There isn’t another controller stop condition (high flow shut-down, etc.) The program will run to completion, spanning days if needed.

Chapter 3 – Advanced Programming when programming the flow device, or when referring to the flow device from other menus. To remove a two-wire device, you must physically diconnect it from the two-wire and then perform a Search operation from the device specific menu. This means a biSensor can only be removed by doing a search from the biSensor menu, etc.. Each flow device in the system needs to be configured with a K-value and Offset pair, or with a pulses/gal value.
Chapter 3 – Advanced Programming is used as efficiently as possible. Setting this value to zero will disable its use to control zone concurrency. High Flow Limit This represents a critical limit for the system. When this value is greater than zero, the limit will be compared against the measured reading from the flow device very minute. If the flow rate reading exceeds the limit for three or four minutes in a row, an alert will be generated.
Chapter 3 – Advanced Programming the zone is considered stable after the delay time. One minute after the delay time a valid flow is calculated (over the last minute interval). Design Flow This is the flow rating for the mainline and is likely different from the design flow of the POC/flow device. When a mainline has multiple POCs of different capacity, the controller will use the constrained design flow to determine the actual available flow for watering.
Chapter 3 – Advanced Programming zone would run concurrently. If program B was running by itself, only three zones would run concurrently. If your system does not have a flow device, then you can control zone currency without having to input design flows for all zones and the mainline, by just using this screen.
Chapter 3 – Advanced Programming Zone Flow Each zone can have a design flow set manually, or it can run through a learn flow cycle and have its “design flow” set automatically. This is useful after doing work on a zone (head changes) or if a program learn flow had a zone that failed to be able to run a single zone or a set of zones through a learn flow cycle. Enter this screen from the top menu level of the Flow Menu dial position. Highlight the Zone Flow Setup and press the ENTR key.
Chapter 3 – Advanced Programming The mainline assignments are made in the Mainline Configure menu of the Flow Menu dial position. Highlight the menu item and press ENTR to show a screen like the one to the right. Assignments are made from the item or device to the mainline. This means that flow device #1 is assigned to a mainline, in this case to mainline 1. If the pipe topology was different, then it should be assigned to the physical mainline.

Chapter 4 – Troubleshooting 4. Press ENTR to test the biSensor. This test will return the current moisture, soil temperature, and two-wire voltage drop. Self-test status No response Cause/Action Zero Reading Two-wire connection to the biSensor is broken – repair wire and connections to the biSensor. Two-wire voltage loss is too high – check other devices in same vicinity for high two-wire voltage loss – repair high resistance connections between controller and devices.
Chapter 4 – Troubleshooting Two-wire – High Current or Shorted The first step in troubleshooting the two-wire is to isolate what works from what does not work. A complex system with many branches in the two-wire path can be difficult to troubleshoot while everything is interconnected. Once a short can be isolated to a single segment of the twowire system, or to a single component, it becomes much easier to fix the problem.

Chapter 5 – Reference block of fifty zones, press the + key. The + and – keys can be used to navigate among each block of fifty zones. There are several additional status screens that are available with the dial in this position. They can be accessed using the NEXT/PREV keys. Detailed Program Status – this screen shown to the right shows some additional information about program A. For convenience, the mainline assignment is also indicated next to the program letter.
Chapter 5 – Reference conditions then use the + or – keys to scroll between each of them. Each pause condition can be cleared by pressing the CLR key, however, if the cause of the pause condition has not be changed, the pause state will return. As seen in this example of a water window pause, it cannot really be cleared with the CLR key. This will clear itself when the water window has expired, or when the water window programming is changed.
Chapter 5 – Reference Pause Switch Rain Switch Rain/OFF days Water Window An open jumper or wired switch will pause all watering on the controller. A CLR will not reset the pause condition until the jumper or switch has closed the circuit, then CLR will reset the pause condition before the delay time has elapsed. Automatically cleared at end of delay time. An open jumper or wired rain sensor that is wet (open) will stop all watering, and will stop all programs from starting.

Chapter 5 – Reference Primary Linked This zone type is used for the first zone in a zone scheduling group. Making changes to a primary zone will automatically make corresponding changes in all linked zones. A biSensor can only be assigned to primary zones. A linked zone will follow the watering and programming of the primary zone that it is linked to. If zone 2 is linked to primary zone 1, then it will follow zone 1.
Chapter 5 – Reference Program Water Windows Enter the water windows screen by highlighting the Set Water Window menu and then press the ENTR key. A sample screen is shown to the right. Water windows can be set for either Weekly (shown on the screen shot) or daily – when moving from weekly to daily, the weekly settings are copied to each day of the week. Selecting daily water windows gives you hourly control of watering for each day of the week, and for each program.
Chapter 5 – Reference Even Days This day interval mode will allow programs to start on even days of the month. Odd Days This day interval mode will allow programs to start on odd days of the month. Odd Days and Skip 31st This day interval mode will allow programs to start on odd days of the month, but will also not allow watering on the 31st of the month, thus maintain a better every two day schedule when crossing to a new month. Soak Cycle Please see a previous section for this information.
Chapter 5 – Reference Date/Time The date and time should be set when the controller is installed, and when it is powered back up after being shut down for an extended period of time. The real-time clock circuit is maintained for several days during a power outage, but will lose track of time after a week or more. Set the date by using NEXT/PREV to select the date field and then adjust the field value using the + and – keys.
Chapter 5 – Reference Flow Menu This dial position provides the programming for flow management and control. Please see a previous section for this data. Refer to page 43, Flow Management & Monitoring. biSensor Menu There are two sub-menu levels in this dial position. Please see a previous section for this data. Refer to page 38, Micro-Climates and Zone Scheduling Groups. biCoder Menu This is the first step is programming the BaseStation 3200 controller – assigning valve biCoders to zone numbers.
Chapter 5 – Reference The after the first valve biCoders have been connected to the two-wire, a Search operation is done to inventory each of the two-wire devices – the valve biCoders will then be available in a list to assign to their corresponding zone numbers. A search operation is done by highlighting the first menu item in the biCoder menu dial position and pressing the ENTR key when search is selected (see sample screen shot).
Chapter 5 – Reference AUX – Rain/Off This function will stop all water for a specified number of days. Setting the days to one, will stop watering for the rest of the day, and will resume normal watering at midnight. The number of delay days may be set between 1 and 365. Use the + and – keys to set the number of days to delay watering.
Chapter 5 – Reference AUX – USB Data The BaseStation 3200 has a USB port that is used for data and program information. As can be seen on the sample screen to the right, there are three basic operations. These functions work with a standard, USB Flash memory device (it will not work with multi-function USB memory devices like MP3 players). Backup – highlighting this menu item and pressing ENTR will write a copy of the current controller program to the USB device.
Chapter 5 – Reference AUX – Budget Program watering budgets are included only for completeness and are not recommended for use. This screen allows the water times of all zones on each of the twenty programs to be adjusted up and down, between 25% and 200% of the zone water time programmed from the zone run times dial position. A better watering strategy is to water deep (at least ½” of water) and then water less often – see the discussion on Historical ET Calendar watering on page 38.
Chapter 5 – Reference Self-Test – Zone Test Doing a zone test will verify communication between the controller and the valve biCoder, activate the solenoid and measure the current and voltage, deactivate the solenoid, and measure the voltage drop between the controller and the valve biCoder. The results are displayed on the screen once the test is complete – see the sample screen to the right. In this example, the solenoid is drawing about 0.18 amps and the two-wire voltage loss is 1.4 volts.
Chapter 5 – Reference Self-Test – Verify and Repair All This function will verify communication with each of the devices on the two-wire. It does not check the valve current nor does it check biSensor readings.
Chapter 5 – Reference Manual Water This dial position provides a way to run a single zone, the zones of a program, or all zones for a specific amount of time. It is most often used for a system test or walk-around. The first menu item is used to set the operation for zones or programs. With the first field highlighted, use the + or – key to toggle between Zones or zones of a program mode.
Chapter 5 – Reference OFF This is the shutdown dial position for the controller. With the dial in this position the controller will not water. Here are the other conditions it enforces: It will continue to take biSensor moisture readings every ten minutes and log them into flash memory. It will power down the two-wire (even if it has been set to always be powered up).
Chapter 5 – Reference Two-wire Devices There are many device types that can be connected in any order along the two-wire system of the BaseStation 3200 controller. This section will enumerate the key types and provide a short description of each. More information can be obtained on the Baseline web site (http://www.baselinesystems.com) under the Learning Center menu, documentation library.
Chapter 5 – Reference and offset and when found during a search operation, will auto-program these values into the controller providing instant operation. Standard sizes include: 1”, 1.5”, 2”, 3” and 4”. Hydrometer There are three lines of brass hydrometers: The BL-BFM line of flow meters are industrial brass for long life and high durability.
Chapter 5 – Reference Pause biCoder The BL-5402 is a biCoder which connects directly to the two-wire, and provides a set of wires that can be connected to a set of normally closed contacts. When the contacts open, a pause condition is sensed by the controller and the associated programs move to a paused state for a specified amount of time. Pause Button The BL-5401 is an outside mountable box with a push button and light.
Chapter 5 – Reference quality. These biCoders have the additional ability to communicate with a moisture biSensor over a shared valve wire, provide the ability to easily install biSensors without having to trench for a dedicated moisture sensor wire back to the controller. BL-5200X – this is the powder coated steel enclosure housing one or two of the powered biCoder boards. Configurations range from 12 to 48 zones per enclosure.
Chapter 5 – Reference BL-Commander The BL-Commander is a handheld radio for activating valves while away from the BaseStation 3200 controller. The radio receiver is powered from the BL-3200X series controller and can be easily moved between controller for field service and repair (see page 34). More information is available on the Baseline web site (http://www.baselinesystems.com).
Appendix – Glossary of Terms Glossary of Terms Auto Calibration The controller is able to determine the water holding capacity (Field Capacity) of soil when using biSensor based watering strategies. A single calibration cycle, or automatic monthly calibration cycles can be scheduled. biCoder This is Baseline’s term for several types of two-wire devices. A Baseline valve decoder is referred to as a valve biCoder.
Appendix – Glossary of Terms MV This is a master valve, and may also refer to a pump start. The controller allows four master valves (MV1 to MV4). By default, all master valves are assumed to be Normally Closed, unless they are specifically programmed to be Normally Open (see below). NCMV This is a normally closed master valve, and it built in to the BL-5402NCMV flow device. NOMV This is a normally open master valve, and it built in to the BL-5402NOMV flow device.
