DXi User Manual 22 Reference
DXi User Manual Chapter 4: Setup This chapter describes every function within the Setup section of the controller. Setup |Page 1|Page 2| Flow WED 5:43:40 PM Communication Learn Flow & Current Omit by Date Current Checks Time & Date All step-by-step directions are started from the above Setup screen. Press or to get to Page 2 and/or 3 of the Setup options.
DXi User Manual Flow Setup Flow WED 5:43:40 PM Flow Sensors Flow Options Flow Sensors Flow Sensors can calculate and report the amount of water, in gallons per minute, travelling through a pipe. For a complete explanation on flow sensors, including basic instructions on how to install a flow sensor, please see Appendix B: Flow Sensors. 1. Flow 2. Flow Sensors 3. to navigate to field to set.
DXi User Manual 4. to enter that field. 5. to switch between options. 6. to set desired option. Press or to the next sensor. Flow Options Flow Options establishes flow limits to aid in the detection of possible flow problems. 1.
DXi User Manual Limits Monthly Limit: The number, in total gallons, that the irrigation system should not exceed per month. If it does, the DXi controller will either generate an alert (and keep watering) or simply stop watering until a new month begins. Watering can also be resumed by increasing the monthly limit. Main Line Limit: The number, in gallons per minute, the flow of the main line shall not exceed.
DXi User Manual Monitoring Flow Once the station flow limits have been established, the flow limit checking (upper and lower limits) may be enabled or disabled. When upper limits have been enabled, all station upper limits will be enforced on an individual station basis. When lower limits have been enabled, all station lower limits will be enforced on an individual station basis.
DXi User Manual Learn Flow/Current For the DXi controller to issue meaningful alerts when there is a flow or current problem, the proper flow and current rates must be “learned” by the system. The Learn Flow/Current command therefore teaches the DXi system the nominal (ideal) current and flow settings to each valve and station. One would typically activate the Learn command for either a new system or when a when a new flow meter has been installed.
DXi User Manual On the 3rd screen, two things: If your new system does not have a flow meter installed, be sure the Include Flow checkbox is blank. If you are running the Learn Flow/Current command due to a new flow meter being installed, be sure the Include Current checkbox is blank. Omit by Date The DXi allows up to 48 days to be excluded from irrigation per year.
DXi User Manual Communication Submaster If the Submaster option is active, that means the DXi controller has a direct link to the Central computer.
DXi User Manual Cloud Connect The Toro DXi product line provides “Cloud Connect” capability. With Cloud Connect, users will have access to the ProMax Connect™ mobile app to enhance their onsite maintenance experience. In addition, Cloud Connect provides users with enhanced diagnostics and Toro customer support.

DXi User Manual Flow Max Warnings and Exception Conditions All warnings referenced in this section are described fully in Chapter 8: Alerts. Please refer to that section for details. Most exception conditions result in warnings being generated at the submaster as well as each Flow Max participant. Different information however will appear at different controller locations depending upon the circumstances.
DXi User Manual Appendix E: Hardwired Communication Troubleshooting Toro® DXi controllers are capable of communication between controllers to allow sharing of flow devices, Master Valves, pumps, as well as communication to Laguna central software. Controllers share communication via a hardwired connection. The hardwired communication is made via the EV-CAB-COMM cable due to its specific direct burial and communication properties.
DXi User Manual DXi COMM BOARD: The DXi-COM-BOARD is seen below in figures 1 and 2. The board has LED indications for 5V and 12V power, and data traffic via the R (Receive), T (Transmit), and D (Direction) LED's. The board has designated inputs for communication coming "IN" from a upstream controller and "OUT" to a downstream controller. Each "IN" and "OUT" port has a polarity indication, "+" or "-" as well.
DXi User Manual Please note, if maintenance is being performed on a controller or a controller is powered down in a group, this will result in generation of communication related alerts. Communication with Laguna Central Software Communication with central software should be robust, especially for submasters communicating to Laguna via an Ethernet LAN connection. Wireless communication to Laguna from the submaster will be subject to errors and retries, especially compared to Ethernet LAN.
DXi User Manual Inspecting Field Wiring: Field wiring problem causes vary, but all typically result in a few types of failures, such as additional resistance, open circuit, short circuit and/or ground leakage. Typical causes for these failures are a severed wire, poor/defective wire splice, defective wire insulator, water ingress or installation of the incorrect/poor quality underground communication cable.
OUT+ ≈ 3.2K ohm IN- ≈ 3.1K ohm, Mega ohms or Open Circuit IN+ ≈ 3.2K ohm DXi User Manual A lower than expected resistance value for any of the measurements in Test 3, are indicative of a ground leak or short in the communication wire. Additionally, resistance values greater than 4K ohm but less than 1Mega ohm are suspect of ground leaks. Test 4 Power down the suspect controller, upstream controller and downstream controller.

Sometimes you will see a product for sale that has a label with a warning along the lines of the following: The warnings is required by California labeling law Proposition 65 (or Prop 65 for short), which is meant to notify individuals in California of exposures to Prop 65-listed chemicals. Prop 65 does not ban the sale of any products containing these chemicals; it only requires warnings.
DXi User Manual How do the California warnings compare to federal limits? It should be noted that California product label warning requirements are not usually the same as federal safety requirements. This causes a variance between warnings on products sold in California and what is required elsewhere in the U.S.A and other parts of the world. This can explain why sometimes you may see a Prop 65 warning on a product sold in California but no warning on the same product sold elsewhere.
