RCS Sure 24/25
Installation Manual
Safety First
In the maintenance and operation of mechanical equipment, SAFETY
is the basic factor which must be considered at all times. Through
the use of the proper clothes, tools and methods of handling,
serious accidents causing injury to you or your fellow workers can be
prevented.
Throughout this manual are listed a number of safety precautions.
Study them carefully and follow them; also insist that those working
for you do the same. Remember, an accident is usually caused by
someone’s carelessness, neglect or oversight.
Note: Ensure the driven device is properly positioned in its full fail
position. If it is not, use the adjustable end of travel stop on the Sure
24/25 (see figure 4) to properly adjust the fail end of travel stop. Only
the fail end of travel may be adjusted. Loosen the lock nut to free the
adjusting screw, then use an allen wrench to turn the screw. The total
adjustment available is +/- 5 degrees.
CAUTION
To prevent the ignition of hazardous atmospheres,
do not remove actuator cover while circuits are live.
CAUTION
Loaded spring inside actuator. Do not attempt to
repair actuator below top gear plate, unless properly
trained on repair methods.

(viewed from the top of the actuator)
Ensure actuator is de-energized and positioned in the
clockwise (fail) position. Ensure the end of travel stop
is properly adjusted. Rotate the screw clockwise to
move the actuator output shaft in a counter-clockwise
direction. Rotate the screw in a counter-clockwise
direction to move the actuator output shaft in a clock
wise direction. Loosen the setscrews on Cam2.
Rotate counter-clockwise until it clears the switch arm
roller of Switch 2.
Rotate Cam 2 clockwise until it comes in contact with
Switch 2’s arm roller and the switch “breaks”. A light
“click” can be heard. Tighten the set-screws on
Cam 2.
Energize the actuator. This will move the actuator to
the opposite end of travel.
Installation
Note: SurePowr actuators can be supplied for clockwise or counter-clock-
wise spring driven rotation (viewed from the top of the actuator). The
spring drive rotation is noted on the actuator name tag and wiring
diagram. Ensure that the actuator has been supplied with the proper
spring drive operation for the application prior to installation on the
driven device.

3.
4.
5.
a.
The actuator is shipped in the power off (fail) position.
Ensure that the driven device is orientated to its fail position
prior to installation of the actuator.
Care should be taken to maintain proper alignment between
the actuator and the device shaft. If the actuator is not in the
correct alignment with the device shaft, repeat the
b.
procedure in Step 1.
Mount the actuator to the device. Ensure the actuator is
centered properly with the device shaft, and then tighten all
bolts and nuts evenly.
Remove the cover bolts located around the actuator motor
and control cover flange.
Terminate field wiring per the appropriate RCS wiring
diagram, supplied with the actuator. Use aminimum of #18
AWG stranded wire.
c.
CAUTION
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.
d. Upon reaching the opposite end of travel, Cam
7 should just engage the roller on Switch 7 so that
the switch just “breaks”. This action will stop the
actuator. Check that the actuator has properly
positioned the driven equipment.
e. If actuator travel is insufficient, rotate Cam 7
slightly clockwise until the cam just clears the roller
of Switch 7. 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.
f. If the actuator has over-traveled, rotate Cam 7
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 7 operates Switch 7 and the
actuator stops. Repeat this procedure until the
actuator is properly positioned. Tighten the
setscrews on Cam 7.
Switch adjustments for counter-clockwise spring fail
operation (viewed from the top of the actuator)
a. Ensure the actuator is de-energized and postioned
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 Cam 7. Rotate
clockwise until it clears the switch arm roller
of switch 7.
b. Rotate Cam 7 counter-clockwise until it comes in
contact with Switch 7’s roller arm and the switch
“breaks”. A light “click” can be heard. Tighten the
setscrews on Cam 7.
c. Energize the actuator. This will move the actuator
to the opposite end of travel.
CAUTION
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.
d. 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.
e. If actuator travel is insufficient, rotate Cam 2
slightly counter-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.
f. If the actuator has over-traveled, rotate Cam 2
slightly 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. Tighten the setscrews
on Cam 2.
6. Operate the actuator electrically several times to ensure
proper operation and to verify that travel limits and stops
are correctly set.
7. De-energize the actuator to verify proper spring failure
operation. Ensure the driven device is properly positioned
in the spring failure position.
8. 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.
9. Replace the actuator cover and cover screws.
10. The actuator is now ready for electrical operation.
