    The core of your TDI system is the TDI Board that manages the integration between your main controller and the stations. In the sections below you will find a description of the layout of the TDI Board and its input and output terminals.

  • Page 8: Station Inputs

    The Flow output terminal is determined by the flow input, but modified by the divisor and pulse width. If the divisor is set to x, then for every x flow input pulses, the TDI will generate an output pulse of at least the specified width.

    For more information, turn to Section 3.1.7, “Connecting the Two-wire” [14]. Warning While the TDI is running, a short on the two-wire will not clear the display and thus it might still display active stations even if they are not active. 2.2.8. Master valve activation Use this terminal to connect a push button which may turn on the master valve when activated.

    7.1.2. Running the Electrical Test The TDI has a built-in test that will activate each station in turn for just one second in order to check if they are responding correctly. The stations must be connected to the solenoids that activate valves in the landscape, and the test can tell whether the stations and solenoids are working correctly in conjunction.

    7.1.3. The Built-in Short Finding Test If you suspect your system has a short somewhere in the field, use the built-in short test in the TDI. This test won't tell you anything you can't already see if you've configured the controller to display voltage and...

  • Page 45: Testing The Two-Wire Path

    The first indication that you might have a short or a fault somewhere on the two-wire path is that the Line Out indicators (the green and red LEDs on the TDI) will flicker very quickly, or be not lit at all.

  • Page 46: Increasing Station Power

    Increasing Station Power There are two stages of testing the two-wire for shorts: you can run a built-in short test from the TDI, and if something seems wrong, you can inspect the two-wire in the field, using a clampmeter. 7.3. Increasing Station Power In case the stations are not giving out enough power for the valves or pumps to pull open, it is possible to increase the power.

  • Page 47: Chapter 8. Troubleshooting In The Field

    (refer to Section 3.1.7, “Connecting the Two-wire” [14]). If the high current disappears, the two-wire is the problem. If the high current remains, the TDI has the fault. To get a more precise idea of how your current reading should be, you should add the standby usage and...
  • Page 48 If the power reading is below 25V The field installation is consuming so much power that the TDI has lowered the power on the two-wire, and you should go locate the problem in the field (See Section 8.4, “When there is a Short Circuit in the Field”...

    The resistance between the station and TDI the is 0.75*R To find out whether your loop is broken, follow this procedure: Open the loop in one end - if the loop goes all the way back to the TDI, just detach one of the two-wires on the controller.

  • Page 51: Dealing With Failing Stations

    Perform an "electrical test" as described in "Running the Electrical Test" in Chapter 7: Troubleshooting from the TDI. This will activate each in turn - if you see stations failing, chances are that they are on a stretch of the two-wire that has been orphaned by a break of the loop in the field.
  • Page 52 • Take the station to the TDI and perform a direct test before replacing it. If the station fails with too high current reading • Check the two-wire between the solenoid and the station for cracks in the insulation or bad connections.

  • Page 54: When There Is A Short Circuit In The Field

    But you can't always be sure that the TDI will be able to detect a short circuit in the field - if the short is in the far end of the cabling, the controller may just experience it as heavy usage. However, the current reading will always reveal a short as the current will be significantly higher than normal.

  • Page 55: Using A Clampmeter

    This means that you can "follow the current" and eventually be led to the short: Figure 8.4. Faulty station Note If your installation loops back to the TDI you must open the loop, or you won't know which way the current is running around the loop and troubleshooting will be almost impossible. Note...
  • Page 56 Make a note of your readings as you'll use these for comparison if you need to locate a faulty branch in the field. • If one of the cables connected to the TDI loops back to the controller, you must open the loop before measuring.
  • Page 57 • If you get no readings from either branch, the problem is on the part of the two-wire leading back to the TDI - perform a binary search (see procedure below) on this part of the cable. • If your readings on one of the branches are the same as when measuring at the controller (This is the first thing you do when troubleshooting the two-wire you move on further out one branch at a time, measuring in every fork you meet (J2, J3, J4 etc.) until you locate the faulty branch).
  • Page 58 Locating the Short When you locate the faulty branch, move on and perform a binary search. See next section. Procedure 8.4. Phase III: Performing a "Binary Search" on a Faulty Branch A binary search can help you locate a problem on the two-wire in a structured manner. The concept of a binary search is this: Find a point on the cable where you know for sure current is running.
