Upon reaching the opposite end of travel, Cam

2 should just engage the roller on Switch 2 so that

the switch just "breaks". This action will

stop the actuator. Check that the actuator has

properly positioned the driven equipment.

If actuator travel is insufficient, rotate Cam 2

slightly clockwise until the cam just clears the roller

of Switch 2. As soon as the cam clears the roller, the

actuator will "bump" electrically towards the end of

travel. Continue until the actuator reaches the full

end of travel.

If the actuator has over-traveled, rotate Cam 2

slightly counter-clockwise, then move the actuator

towards the fail position electrically. Stop and

electrically reverse the direction of travel. Move the

actuator until Cam 2 operates Switch 2 and the

actuator stops. Repeat this procedure until the

actuator is properly positioned.

Rotate Cam 4 until it comes in contact with Switch

4's arm roller and the switch just "breaks". A light

"click" can be heard. Rotate the cam slightly

counter-clockwise. This ensures that Switch 4 will

"break" just prior to the actuator reaching the

extreme opposite end of travel. Tighten the

setscrews on Cams 2 and 4.

Switch adjustments for counter-clockwise spring fail

operation (viewed from the top of the actuator)

Ensure the actuator is de-energized and positioned

in the counter-clockwise (fail) position. Ensure

the end of travel stop is properly adjusted. Rotate

the screw counter-clockwise to move the actuator

output shaft in a counter-clockwise direction.

Rotate the screw in a clockwise direction to move

the actuator output shaft in a clockwise direction.

Loosen the setscrews on Cams 2 and 4. Rotate

both clockwise until they clear the switch arm

rollers of switches 2 and 4.

Rotate Cam 2 counter-clockwise until it comes

in contact with Switch 2's roller arm and the switch

"breaks". A light "click" can be heard. Tighten the

setscrews on Cam 2.

Rotate Cam 4 counter-clockwise until it comes in

contact with Switch 4's arm roller and the switch

just "breaks". A light "click" can be heard

Closely monitor the electrical stroke, as the travel limit

switches are not yet properly adjusted. Ensure the

actuator does not over-travel and damage the driven

equipment.

Rotate Cam 4 slightly further in the counter-clock

wise direction. This ensures that Switch 4 will

"break" just prior to the actuator reaching the full

fail position. Tighten the setscrews on Cam 4. Use

care to not over-tighten the set screws.Energize

the actuator. This will move the actuator to

the opposite end of travel.

Upon reaching the opposite end of travel,

Cam 1 should just engage the roller on Switch 1 so

that the switch just "breaks". This action will stop

the actuator. Check that the actuator has properly

positioned the driven equipment.

If actuator travel is insufficient, rotate Cam 1slightly

counter-clockwise until the cam just clears the

roller of Switch 1. As soon as the cam clears the

roller, the actuator will "bump" electrically towards

the end of travel. Continue until the actuator

reaches the full end of travel. If the actuator has

over-traveled, rotate Cam 1 slightly

counter-clockwise, then move the actuator

towards the fail position electrically. Stop and

electrically reverse the direction of travel. Move

the actuator until Cam 1operates switch 1 and the

actuator stops. Repeat this procedure until the

actuator is properly positioned.

If the actuator has over-traveled, rotate Cam 1

slightly clockwise, then move the actuator towards

the fail position electrically. Stop and electrically

reverse the direction of travel. Move the actuator

until Cam 1 operates switch 1 and the actuator

stops. Repeat this procedure until the actuator is

properly positioned.

Rotate Cam 3 until it comes in contact with Switch

3's arm roller and the switch just "breaks". A light

"click" can be heard. Rotate the cam slightly further

in the clockwise direction. This ensures that Switch

3 will "break" just prior to the actuator reaching the

extreme opposite end of travel. Tighten

the setscrews on Cams 1 and 3. Use care

to not over-tighten the set screws.

Operate the actuator electrically several times to ensure

proper operation and to verify that travel limits and stops are

correctly set.

De-energize the actuator to verify proper spring failure

operation. Ensure the driven device is properly positioned in

the spring failure position.

If the actuator is supplied with an optional feedback

potentiometer and/or position controller, verify proper

calibration of input and output signals after making cam and

stop bolt adjustments.

Replace the actuator cover and cover screws. Before

installing the cover, make sure both flange surfaces are clean

and free of any deris, and that the cover o-ring is in the

machined groove in the lower housing and properly seated.

Also make sure that the indicator beacon is in the proper

orientation.

10.

The actuator is now ready for electrical operation.
