|Watch Assured Automation’s EV Series Electric Actuator Product Demonstration. This video shows how to wire an Assured Automation EV Series Electric Actuator for 115 Volt AC Wiring. The EV Series is equipped with a reversible motor and end of travel limit switches.
Hello and Welcome to Tech Talk
My name is Brian and in this video we will be showing you how to wire an Assured Automation EV Series electric actuator. This will be for 115 Volt AC wiring only. The EV actuator is equipped with a reversible motor and end-of-travel limit switches which stop the motor in each direction. External wire leads are provided so you can wire the electric actuator without removing the cover.
Before we begin be sure that your 115 Volt AC supply power is disconnected to avoid shock. To drive the unit to the open position or the counter clockwise direction, locate the white wire, number 1, also referred to the common wire. Then locate the red wire, number 5, also referred to as the counter clockwise travel wire. When AC power is applied to these wires, white and red, the actuator will run in a counterclockwise direction until it reaches the end of travel, or approximately 90 degrees.
To drive the unit to the closed position or clockwise direction, locate again the white wire, number 1, also referred to as the common wire, then locate the black wire, number 3, also referred to as the clockwise travel wire. When AC power is applied to these wires, white and black, the actuator will run in a clockwise direction until it reaches the end of travel or approximately 90 degrees.
Please note at the end of each travel position there are internal limit switches which open the circuit and stop the motor. These switches also send supply voltage back out for those who wish to confirm the travel position – open, closed or both.
The blue wire, number 2, will be used to indicate the closed position and the yellow wire, number 4, will be used to indicate the open position. These wires will have power on them at the end of each travel position, so if you are not using these wires for travel indication please be sure the ends of these wires are properly taped off and separate from one another to prevent a short or shock.
One final feature is the manual override. This allows the user when power is not present to mechanically move the actuator shaft in a counter clockwise or clockwise direction. Again power should be disconnected when manually overriding the actuator. For manual override operation, first remove the black cap as shown here. And turn the actuator shaft by applying an adjustable wrench to the flats of shaft. You can turn this in a counter clockwise or clockwise direction for your desired rotation.
The wiring we just discussed can be found on the inside cover of the actuator, or you can access the drawing online from our website at AssuredAutomation.com. Just click on the tab “Valve Actuators” under the Accessories header.
