BQSR Series Spring Return Electric Actuator

Connecting power to terminals 2 and 4 will cause the motor to rotate counterclockwise (CCW). The brake is activated when the normally open contact of the OLS is closed to keep the actuator in the counterclockwise position. Connecting power to terminals 2 and 6 will cause the motor to rotate clockwise (CW). The brake is activated when the normally open contact of the CLS is closed to keep the actuator in the clockwise position. Connecting power to terminals 2 and 5 will activate the brake to keep the actuator in the intermediate stop position. Once the power supply is lost, the brake will be released and the actuator will return to the fail-safe position (limited by the adjustable limit switch).

    *EACH ACTUATOR SHOULD BE POWERED THROUGH IT'S OWN INDIVIDAL SWITCH
    OR RELAY CONTACTS TO PREVENT CROS SFEED BETWEEN TWO OR MORE ACTUATORS.

    Operation Notes：
    1.Power to terminal 2 & 4 will drive motor CCW.Brake energizes when NO of OLS closes to hold actuator in CCW position.
    2.Power to terminal 2 & 6 will drive motor CW.Brake energizes when NO of CLS closes to hold actuator in CW position.
    3.Power to terminal 2 & 5 will energize brake and hold actuator in intermediate STOP position.
    4.Loss of power will release spring clutch and return actuator to fail position (limited by adjustable stop).
