Freque tly Asked Questions Isoflow Model ISF-302-00 also applies to ISF-306-00The following questions have been asked about the Isoflow product. Before calling fortechnical support, please review to see if your question may be answered here. 1. What does the Isoflow do? The Isoflow is a solid state device that has one flow sensor input and two flow outputs that are optically isolated from each other. This allows a flow sensor signal to be shared by more than one irrigation controller, pump control or other device, without causing voltage feedback, change in signal strength or other signal distortions. In fact all of the circuits; incoming power supply, flow sensor input, flow outputs and control circuits are isolated from each other. 2. Why do I need an Isoflow? Flow sensor input circuits for irrigation controllers are very different from valve control circuits. They supply power to the flow sensor and at the same time, read the digital output of the flow sensor and convert it into a flow rate. If you attempt to connect one flow sensor to more than one controller, the power supplied by each is cross-connected and will back feed into the other controllers flow circuit. If this problem isn’t enough, the signal strength changes and the controller circuitry interprets this as incorrect flow. 3. Can I use it to connect a flow sensor to an irrigation controller and a pump station control? Yes, or you can share connections to a fertigation control, a SCADA system, a data logger or any other device that needs a flow sensor input. Many of these other control products do not use the raw flow sensor signal but convert it to an analog signal. Because this type of input is either a change in voltage or current proportional to flow, it is even more critical that the flow sensor signal be isolated before it gets to the analog converter. The Isoflow may be used in retrofit applications to allow an additional system to share a flow sensor without affecting the settings of an existing analog transmitter. Rev D 021612

FAQ pg 24. Does it need power? Yes, the Isoflow is a powered device. Connect the two yellow leads to 12-24 volt AC or DC power. Remember to connect the Yellow with White Stripe wire the DC + source. Some controllers have power output connections. Always check with the controller manufacturer for their recommendations. You may also use an accessory plug-in type power supply purchased locally. As good practice, install an inline 250 volt, 125 mA slow blow fuse in series with the power lead.5. Does it also isolate master valves? No, an Isoflow device only isolates the flow sensor. Check with the controller manufacturer for their recommendations for sharing a single master valve between two controllers.6. What are the blue and orange wires for? In addition to providing two isolated flow outputs, the Isoflow contains circuitry that allows these outputs to be switched on or off by an external signal. Several “smart” irrigation controllers have the capability of sensing flow even when no irrigation program is running. If flow is detected with no programmed irrigation cycle running, the flow is considered “unscheduled” and will cause an alarm condition. If two controllers are sharing a single flow sensor, one may operate while the other is not. Let’s say Controller “A” is running a program and Controller “B’ is not. Flow going through the sensor will be received by both controllers. “A” will read flow normally but “B” will see this flow as unscheduled and go into the alarmed state. To prevent this from happening, the orange and blue leads are connected to terminals of the “A” controller that will supply 24 VAC whenever the controller is running. This is usually a “normally closed master valve circuit” or a “pump start circuit”. When this pair of wires is energized, the flow signal to the “B” controller is blocked. Similarly, the other pair of orange and blue leads with white stripes are connected to the NC master valve or pump start circuit of the “B” controller and block the flow signal to “A” whenever the “B” controller is operating. In cases where both controllers are operating at the same time- both sets of orange and blue wires are energized, the flow signal is conducted to both controllers so they both read flow. If neither controller is operating an active program nor either pair of orange and blue wires is energized, then the flow signal is also transmitted to both controllers so they can both detect “unscheduled flow”. In applications where two isolated flow signals are required continuously, do not use the orange and blue leads.7. Can I use an Isoflow with other sensors? Yes, in addition to using the Isoflow with Creative Sensor Technology sensors, it may be used with any two-wire impeller type flow sensor manufactured by Data Industrial/Badger Meter. Please call technical support to verify other devices. It cannot be used with Hunter HFS sensors.8. Can I use a Combiflow with the Isoflow product? Yes, the Combiflow device may be connected in series with Isoflow. With this combination of products you can accept the signals from two flow sensors combine that total flow rate into one

FAQ pg 3 output and use that as the input to an Isoflow to provide an isolated flow signal to two individual irrigation controllers. With this combination of products, either controller can receive all the flow information from both flow sensors.9. I have my controller set up to operate a normally open master valve; can I still use the Isoflow to prevent “unscheduled flow” alarms? Yes, in this case, you need to supply 24 VAC power whenever the controller is on. The normally open master valve circuit is just the opposite, only powering the valve when it needs to be closed. Use your controllers pump start circuit. Sometimes it’s another set of terminals and sometimes its Station Output 1. Check with the controller manufacturer.10. Where should I mount the Isoflow? The Isoflow should be mounted in a dry location, I prefer a controller pedestal or wall mount enclosure. It should also be within the distance limits of the flow sensor, 2,000 feet for CST sensors using the recommended cable. Finally, the Isoflow should be connected between the flow sensor field wiring and any control inputs. There is one pair of leads to connect to the flow sensor and two sets of flow output leads to connect to the irrigation controller flow inputs. If any analog converter devices are required, make sure the Isoflow is installed so one flow output is attached to the analog converter flow input.11. Will it work with all kinds of irrigation controllers? The Isoflow will operate with any irrigation controller equipped to receive a two wire flow sensor input. In some instances, an accessory device may be required to change the signal format. Check with Creative Sensor Technology regarding the proper connection to your controller.

FAQ pg 412. Can you provide wiring diagrams?Note: 1. All wire connections are made to the flying leads as shown. 2. Power can be any 12 to 24 Volt, AC or DC supply. If you use a DC supply be sure to connect the + and - terminals correctly. 3. The wire colors are shown to match the CST flow sensors. If others are used, observe the + and - polarity.

ISO6 ISF-306-00 Isolator Installation GuideOperation:The ISO6 signal control device allows up to six irrigation controllers or other control devicesto share one flow sensor by electrically isolating its flow outputs. The ISO6 is compatiblewith all CST flow sensors and most flow sensors producing a square wave outputproportional to flow rate. It is not compatible with Hunter HFS devices. In addition, sixcontrol inputs are provided allowing the device to selectively block flow outputs tonon-active channels during operating cycles.Example: Many irrigation controllers can read and react to unscheduled flow events.The control inputs allow the operating controller to switch off the flow signal to the inactivecontrollers preventing false alarms.Control Logic: If no 24 VAC control signal is applied to any of the six control inputsthen all six flow output channels are active. If 24 VAC is applied to Control Input pair 1 thenflow output 1 is active and outputs are blocked to flow outputs 2-6. If 24 VAC is applied toControl Input pair 2 then flow output 2 is active but flow is blocked to outputs 1,3-6 . Thesame logic condition repeats for the remaining four inputs. If more than one controller isactive at the same time and 24 VAC is applied to more than one control input pair, then theflow output is active to the corresponding flow output and blocked to the remaining inactivecontrollers. If all six control inputs receive 24 VAC, then all six flow outputs are active.Use the 24 VAC Normally Closed (NC) Master Valve output from each controller as thecontrol input signal. If Normally Open (NO) Master Valves are used, then use the PumpStart circuit as the control signal source.Note: This device does not operate the master valve. Additional relay logic may berequired to operate one master valve from several controllers.Control inputs are also electrically isolated from each other, the flow input and outputs andthe power supply.

PWY-400-S01 PATHWAYPage 2.The Controller Module is installed at the irrigation controller and the Field Module is installed in an existing zonevalve box near the proposed location of the new flow sensor and master valve. The control and common wiresof this “host” zone valve become the communications path between the Pathway modules.The Controller Module requires a 24 VAC power supply of sufficient size to operate its circuitry and solenoidvalves connected to it. Alternatively, some controllers offer 24VAC auxiliary power for hand-held remotes orrain switches that may also be used to power the Pathway Control Module.New wire installation is only required to connect the Field Module to the new flow sensor and master valve.Both modules incorporate “day-light” bright LED’s providing feedback to confirm operation or assist introubleshooting is necessary.This product is compatible with most irrigation controllers equipped with flow monitoring functions. It may beused to add a flow sensor, a master control valve or both. If you have questions specific to your controllercompatibility or application, please contact CST prior to field installation.Sensor compatibility:The CST PWY Field Module has been optimized to work with CST sensors and is designed for 5 voltcompatibility. While operation with 3rd party sensors may be possible, CST cannot guarantee that thesesensors are operating within the manufacturer's specification limits and as such is not responsible for reliableoperation of same.Controller compatibility:The CST Pathway System has been tested with many irrigation controllers. A partial list of compatible controlproduct includes: ET Water Hunter ACC Irrisoft Controller Link Rain Bird ESP LXMEF or ESP LXME with flow module Rainmaster Eagle Weathermatic Smartline with Smartlink Check with CST for other controllers.Field Wiring / Distance:The CST Pathway System has been demonstrated to operate reliably on a variety of common irrigation wiringsystems. However, as the signal quality is dependent upon existing wiring configuration, insulation quality,splices, distances, etc., CST cannot assure operation in every situation. Please contact CST prior to installationfor recommendations and guidance. Creative Sensor Technology, Inc.

PWY-400-H02 PATHWAYPage 3 Pre-Qualifying a SiteThe Pathway system uses field wiring as a signal carrier between the two control modules. The Pathwaysystem has been designed to operate using existing, direct burial irrigation valve control wire. In mostsituations it will provide a simple way to retrofit a flow sensor and/or a master valve to a site. However, if there isextreme distance between the modules, over 1500 feet, or if the wire insulation is defective or splices are poorlymade, the Pathway System may not work.The following instructions outline a simple test using the Pathway modules that can pre-qualify the wirepath in thirty minutes or less.Step 1- Identify the Host zone valveThe first priority is to find a working zone valve close to the proposed location of the flow sensor/master valve tominimize the amount of new wire installation. Identify the irrigation controller zone number that operates thisvalve. You will need to disconnect this zone wire at the controller for the test.Step 2- Connect the Field ModuleDisconnect the solenoid leads from the field wiring. Confirm which field wire is the power wire and which is thecommon. The insulation of the power wire is usually red or some color other than white. The common wire istypically white in color. Re-connect the zone valve power wire to the Purple lead of the field module. Connectthe zone valve common wire(s), there may be two or more, to the Blue lead on the field module. Do not connect any other leads and leave the valve solenoid disconnected.Step 3- Connect the Controller ModuleAt the irrigation controller location, you will need a temporary 24 volt power supply for the Pathway Controllermodule. Use the 24 VAC auxiliary power output of the controller if available. If not, use a spare irrigationcontroller transformer or other plug in style 120 Volt to 24 VAC power supply for this test. Make sure the powerto the irrigation controller is off before proceeding. Disconnect the power wire to the host zone valve from theirrigation controller terminal strip. Reconnect this wire to the Network “L” terminal on the Pathway controllermodule. Connect a wire from the controller valve common terminal of the controller to the Network “C” terminalof the controller module. Leave all common wires from the field connected to the controller common terminal.Connect 24 volt power leads to the Power terminals on the lower left side of the Pathway controller module.Power up the controller and the module.Step 4- Observe the LEDsWhen power is applied to the controller module, observe the Power and Network LEDs. They should blink threetimes, then the red Power LED and the green Network LED should blink continuously. Next check the fieldmodule. If its green Network LED is also blinking continuously, then the wire path will support the PathwaySystem and you may proceed with the permanent installation of the flow sensor and master valve. If theNetwork LED remains off, check your wire connections and polarity, this indicates an open circuit. There is notwo-way communication between modules unless both green Network LEDs blink continuously. Take correctiveaction if possible.Do not proceed with the installation of the Pathway or the flow sensor and master valve until youobserve blinking Network LEDs on both devices.

PWY-400-H02 PATHWAYPage 4.Step 5– Corrective ActionA. If the two Network LEDs do not blink con nuously, then there is a problem with the exis ng wire. 1) Re‐check the connec on from the valve common terminal of the irriga on controller to the Network common terminal of the Pathway Controller Module. There must be a connec on between the Network Common on the Pathway Controller module and the wire going to the field host valve loca on. It is not a good prac ce to use a wire terminal to connect mul ple wires. A be er way is to join a separate wire for each terminal connec on to the commons coming in from the field with a large wire nut and then connec ng the single wire to each terminal. Power up the Pathway and see if the green LEDs now blink con nuously. 2) If not, recheck the common wire(s) at the host valve loca on. If there were two common wires connected to the solenoid originally, they both need to be connected to the Blue lead of the Pathway Field Module. 3) If the green LEDs are s ll not blinking, recheck the common splices at zone valves located between the irriga on controller and the host valve. Re‐splice as necessaryB. Although highly unlikely, if the green network LEDs do not blink con nuously, then the exis ng wire path will not support the Pathway. Installa on   Step 1.  Make connec ons at the host valve and Pathway Field Module permanent.   NOTE: Always disconnect Power from the irriga on controller and Pathway Controller Module  before making any wire connec ons.   Do  not reconnect power un l both modules of the  Pathway system are wired. Step 2. Install the flow meter/master valve wiring  A. Verify that the flow meter/master valve is equipped with a two wire contact closure pulse type output. The Pathway F02 Field Module will only work with this type of output.B. Install wiring from the host valve box to the loca on of the new flow sensor and master valve. 1) Four conductors are required: two for the flow sensor and two for the master valve solenoid. 2) We recommend the use of a 2 pair twisted, shielded direct burial cable. 3) The distance between the Pathway Field Module and the flow meter/master valve may be up to 1500 feet. Size the conductors to the power requirement of the solenoid. Creative Sensor Technology, Inc. Rev PWY H02 716 www.creativesensortechnology.comPO Box 426, Rochester, MA 02770 Ph: 508-763-8100
