This is the wiring instructions for the B Series Electric Actuator by Assured Automation

Assured Automation: your source for Manual and Automated Valves & Flow Meters.

The B Series is a reversing motor actuator with end of travel limit switches to stop the motor in either direction.

A wiring diagram can be found on the inside cover of the actuator.

Safety First: Make sure all power is off.

To access the terminal strip remove the gray visual indicator cap and remove screws from the cover.

For AC Voltage Units-

To open or drive the actuator in the counterclockwise direction, apply power to terminal 1 and terminal 2. The actuator will turn counterclockwise until it reaches the internal limit switch and shuts off.

To close or drive the actuator in the clockwise direction, apply power to terminal 1 and Terminal 3.  The actuator will turn clockwise until it reaches the internal limit switch and shuts off.

For DC Voltage Units-

To open or drive the actuator in the counterclockwise direction apply positive DC voltage power on terminal 2 and negative terminal 1. The actuator will turn counterclockwise until it reaches the internal limit switch and shuts off.

To close or drive the actuator in the clockwise direction, apply negative DC voltage on terminal 3 and positive on terminal 1.  The actuator will turn clockwise until it reaches the internal limit switch and shuts off.

Auxiliary feedback limit switches may be ordered but are not in the basic unit. Contact sales for additional information.

To engage the manual override, disconnect power

For the 300 and 500 Series -Pull de-clutching position indicator knob up and hold.Engage wrench on exposed shaft drive flats and move back and forth to disengage output shaft from drive train.After disengagement, rotate in desired direction. Once manual rotation is complete, remove the wrench and release the knob.
