Summary of Contents for Signal SDS Series

  • Page 2 Introduction Thank you for purchasing a SIGNAL SDS Series irrigation controller. The SIGNAL SDS Series is an Australian designed and manufactured irriga- tion control system, designed for ease-of-use programming, while allowing for the complex requirements of both landscape and agricultural applica- tions.
  • Page 3 Safety Information SDS Series The SDS Series of controllers are designed to operate on low voltage 36VDC. Use only the power supply included with the controller. The power supply must be installed to comply with local electrical codes. Prior to digging or trenching check with your local utilities for any under- ground services.

  • Page 42: Inputs

    If this is the case, the time for the electrical signal to be initiated and a valve to electrically and hydraulically respond may be beaten by the high pressure cut-out. A pressure sustaining/relief valve can be installed that is sized to slow down the pressure increase if a valve fails to open but not completely prevent a pressure increase that would override a HP cut-out in a closed head condition.

  • Page 46: Hydrosector Programming

    Programming SDS Series HydroSector™ PROGRAMMING: HydroSector™ INTRODUCTION: The HydroSector program is a conversion of the standard irrigation programs • into a linked sequence of matched-precipitation HydroZones. Each Zone would typically be a number of matched precipitation stations. For example, program 1 would become matched precipitation zone 1, program 2 would become matched precipitation zone 2, etc.

  • Page 47: Hydrosector, Steps

    Programming SDS Series HydroSector™ STEPS: Check the current station/valve wiring within the [TWO-WIRE] then [>] [Assign Valves] menu. When using HydroSectors, stations should be wired sequentially. For ex- ample, a typical system may be set up as follows: HydroSector 1 using stations 1—10, HydroSector 2 using stations 11—20 and so on.

  • Page 48: Auto-Programming Feature

    Programming SDS Series AUTO-PROGRAMMING FEATURE: The auto-programming option assigns time or volume of water to each valve & stn within the HydroSector from a total value entered for each H/Sector. If Auto programming is not selected go to Program Entry display and program as normal.

  • Page 50: Fault Finding

    Fault Finding SDS Series FAULT FINDING THE CONTROLLER: SDS Series controllers have been designed for simplified service and repair. The controller does not require a service technician for on-site electronic repair - instead utilising plug-in replacement PCB modules. The principle components of the controller consist of: A mother board which contains the internal PCB power supply, lightning protec- tion and plug-in module interfaces.
  • Page 51 Fault Finding SDS Series If it is suspected a fault is present at the controller and not in the field cabling or DataValves, proceed as follows: Remove the four front keypad panel screws and carefully lift to one side, press any key on the keypad to ensure the output is switched on.

  • Page 52: Current Draw, Datacoils

    Fault Finding SDS Series CURRENT DRAW: DataCoils draw current as follows: SD2NC: Idle = 1.5 mA | Running = 16 mA SD3NO: Idle = 1.5 mA | Running = 21 mA SD3LT: Idle = 1.5 mA | Running = 1.5 mA If a total current draw exceeds 1500mA, the controller will indicate a short circuit condition.

    This fault finding operation requires a clamp-on milliamp meter with a range down to 20 milliamps and a SIGNAL two-wire fault finding tool (SD-RB). If this is not available, in an emergency, a suitable 5-10 watt 250 Ohm wire wound resister can be connected in series with the two-wire cable.

    Fault Finding SDS Series ADDITIONAL FAULT FINDING: On initial installation, great care should taken to avoid grit contamination entering the Data- Coil plungers. Ensure the system is properly flushed before start-up to avoid dirt/grit contam- ination of the piping. If a coil malfunctions, but is still reporting as online with the correct LED indication, it is al- most certain that the coil plunger is jammed by grit.

    Next, plug your Wi-Fi Module into the RS-232 port underneath your controller. Once you do so, the little green LED should begin to flash rapidly. To connect your SDS Series controller online with the Wi-Fi module, the following fields need to be completed: Set WiFi SSID, WiFi Passkey, Device ID and Device Password.
