    The common wire is almost certainly white and in turn runs from your controller to your cylinder and then to all the other valves in your purge system. If something happens to an interruption in your common wire, each valve may not light up when activated after being cut.

  • Most sports field managers have the know-how on how to replace a broken head, and in most cases can repair another broken hose if necessary. However, while this is an electrical troubleshooting of the system, most will choose to use an experienced watering table saw to diagnose repairs and problems. Of course, you have to pay for this. Even if there is a lot of money to spend on irrigation maintenance, there is a good chance that a good irrigation contractor will lag behind in efficiency and not be able to get to the goal right away. Therefore, as a general rule, the ability to diagnose and fix electronic problems in a system should be a valuable skill that should be part of your overall set of skills tools. In this article, many will go over basic troubleshooting methods in an attempt to shed light on the mysteries of this topic.

    sprinkler valve wiring troubleshooting

    Usually, power troubleshooting makes a lot of sense. To better understand the process, the site is very important for understanding the complete electrical anatomy of the system. Of course, all systems are different, but once we understand what can happen to the system electrically, my partner and I can tweak our methods to debug and repair each system.

    The electrical anatomy of a system consists of three main accessories: controller, field wiring, and / or electrical solenoid valves. Basically, in cases where the controller sends a 24 volt mark to the valve through the external wiring, the 24 volts causes a specific valve to open and water can flow through the valve to the precision heads. Since everything starts up far from the controller, we must start diagnostics at this point. The controller is plugged into an old 120 volt outlet. First we need to make sure it works. Transformer stabilizer converts voltages immediatelye 120 to 24 volts before entering the electronics into the regulator. When the torque range is on, 24 volts are considered to be supplied to the valve solenoid valve via external wiring.

    When all 24 volts pass through the wires around the solenoid, an electromagnetic field is created, which usually pulls up a certain metal piston inside the solenoid. This allows water to bypass the new solenoid and enter the chamber below the diaphragm of the current valve. When the force of the water is balanced above and below the diaphragm, this diaphragm lifts the water and flows through the valve and downstream, holding the heads in place.

    Now that we have a better understanding of the basics of energy flow in the system, we can begin the troubleshooting process. The main diagnostic tool is a multimeter, which can measure the test voltage sent by the controller and our own resistance (measured in ohms) through this special field wiring. A decent multimeter can be purchased for less than $ 20 in many cases and is essential to troubleshootmalfunction.

    On the WE controller, we start to test the resistance of most cables in the field, and you will see the valves. This gives us a quick overview of the general electronic “state” of the system. We do this by turning the multimeter, which sets the setting (…) to “Ohm”. If our controller doesn’t work, take a probe and touch the common terminal and keep touching another probe pointing towards the numbered terminals. You should find values ​​between 20 and 55 ohms depending on the type of valve you are testing. If you are getting very high readings, it could be a knot on a particular cable, or a bad connection. When we get an infinite amount of attention (â), we have an open circuit, and that could also be an open wire.

    Problems of this type can actually be too difficult to detect as they can be buried underground. Testing the connections was a good start. If the problem is underground, you can probably use the wire locator job to determine the nature of the localization problem. If readThe valve resistance is very readily available, probably a defective wiring in the solenoid valve. The solenoid needs to be replaced and it is fairly easy to fix. First rinse with water around the device. Then cut the two wires that lead it to the broken solenoid. Unscrew those bad solenoids and screw in new ones. Then secure the 3 wires with waterproof clamps. [Note: it doesn’t matter which wire goes to the common wire, and if you know it, it goes to the wire valve.]

    The effectiveness of a magnet can also usually be tested on a valve. Just loosen the two wires going to the main solenoid and check the strength (in ohms). You should read my article here how you did it with the controller. If the readings are unique, the problem is with the field wiring.

    Then use the controller to light up the problem area. Install the multimeter so that the voltage is measured, and be sure to touch one probe with a common connection, and the other to the working zone device. The controller should supply a 25 volt signal (plus or minus 2). If the endThe controller outputs less than 22 volts, the problem is in the controller. If your controller is sending the largest zero voltage, look for a burnt out stiffener. If there is a fuse in the controller, it will work, but there will be no excitation voltage. You can also easily check the current voltage of the valve by touching a commercially available sensor on each of the wires leading directly to the valve. This should usually be the same value as on the controller. If the parts are different, the problem is where the wires are in the field.

    Troubleshooting electrical systems is often daunting because it is usually shrouded in mystery. However, there is a terrible sense in this process. It is my hope that by understanding the basic anatomy of a system’s strength and applying the simple diagnostic techniques we have explored, this topic will become less daunting and / or accessible.
