Irrigation pump start relay wiring diagram. Run a single wire from the common terminal on the controller to one of the yellow wires on the pump start relay. Since the controller outputs 24volts ac power and most pumps require anywhere from 110 220 volts ac the pump relay acts as a step up transformer to route additional power to the pump and activate it. Wiring the pump relay. Use wire nuts to make the connections and verify they are secure. This video describes how to test a pump start relay for an irrigation system that uses a pump to draw water from a lake or other large water supply. This device is imperative when you are using a pump to supply water to your irrigation system.
The relay changes the irrigation timer to normal household voltage. This is a basic pump start wiring diagram for most controllers. A pump start relay serves as a switch that activates 110 220vac power to the pump when the generation 2 smart sprinkler controllers master valve is enabled. Mount the pump relay a minimum of 15 feet from both the irrigation control box and the pump as electrical interference can occur if the devices are mounted in close proximity to each other. Anytime a zone is activated the pump relay is activated to pressurize the system with water. Pump start relay wiring.
Run a single wire from the pmv terminal on the controller to the other yellow wire on the pump start relay. When wiring a pump relay. Lawn sprinkler pump wiring duration. Any pump start relay wired to an irrigation controller should have all unused station wires connected to the last used station wire. The following diagrams show wiring details for pump start relay and pump motor starter wiring for various rain bird controllers. Since the generation 2 controller outputs 24vac a pump start relay is required when using a pump with the generation 2.
Suitable for conventional wiring or two wire decoder activation allows flexible installation options provides a solution for irrigation controller and pump start relay installations that have insufficient power to activate the pump includes solid state relay and local 24 vac transformer for simple psr activation. The yellow wires in the lower wiring compartment of the pump start relay are to be attached to your irrigation controller. Run a single wire from the mvpump terminal on the controller to the other yellow wire on the pump start relay. A pump start relay is an electrical device that allows your irrigation timer to communicate with the pump. Install pump start relay cover plate and four screws.
