Orbit Pump Start Relay Wiring Diagram

An Orbit pump start relay is used to control the operation of an irrigation pump. It is designed to work seamlessly with an irrigation timer, providing a reliable and efficient means of controlling the pump’s operation. In this article, we will discuss the wiring diagram for an Orbit pump start relay in detail.

What is a Pump Start Relay?

A pump start relay is a device that allows an irrigation timer to control an electric motor for a pump. This device is used primarily in irrigation systems to control the operation of a pump.

The pump start relay works by sensing the presence of voltage in the irrigation system. When the irrigation timer sends a signal to turn on the pump, the pump start relay senses the voltage in the system and activates the pump. When the irrigation timer sends a signal to turn off the pump, the pump start relay deactivates the pump.

Pump start relays are essential for the proper functioning of an irrigation system. They ensure that the pump operates only when required, reducing energy consumption and prolonging the life of the pump.

Orbit Pump Start Relay Wiring Diagram

The wiring diagram for an Orbit pump start relay is relatively simple. It consists of four wires: a ground wire, a common wire, a pump wire, and a valve wire.

The ground wire is connected to the electrical ground of the system. The common wire is connected to the common terminal of the irrigation timer. The pump wire is connected to the terminal on the pump that supplies power to the motor. The valve wire is connected to the terminal on the irrigation timer that controls the irrigation valve.

Connecting the Pump Start Relay to the Irrigation Timer

To connect the pump start relay to the irrigation timer, follow these steps:

  1. Turn off the power to the irrigation system.
  2. Connect the green wire from the pump start relay to the electrical ground of the system.
  3. Connect the white wire from the pump start relay to the common terminal of the irrigation timer.
  4. Connect the yellow wire from the pump start relay to the terminal on the pump that supplies power to the motor.
  5. Connect the red wire from the pump start relay to the terminal on the irrigation timer that controls the irrigation valve.
  6. Turn on the power to the irrigation system.

Frequently Asked Questions

1. Why do I need a pump start relay?

A pump start relay is essential to the proper functioning of an irrigation system. It ensures that the pump operates only when required, reducing energy consumption and prolonging the life of the pump.

2. Can I install a pump start relay myself?

Yes, you can install a pump start relay yourself. However, if you are not comfortable working with electrical wiring, it is recommended that you hire a licensed electrician to do the installation for you.

3. What is the difference between a pump start relay and a pressure switch?

A pump start relay is used to control the operation of an electric motor for a pump. A pressure switch is used to turn the pump on and off based on the pressure in the system.

4. How do I know if my pump start relay is working properly?

Check to make sure that the pump starts and stops as expected. If the pump does not start or stop as expected, there may be an issue with the pump start relay.

5. Can I use a pump start relay with any type of pump?

No, not all pumps are compatible with a pump start relay. Check the specifications of your pump to make sure that it is compatible with a pump start relay before installing one.

6. What is the lifespan of a pump start relay?

The lifespan of a pump start relay depends on a variety of factors, including the quality of the device, the frequency of use, and the operating conditions of the system. In general, a pump start relay should last between five and ten years.
