Installation Instructions

This method should not be used for outside air damper appli-

cations. The damper will never go to the full close-off position.

This may cause coils to freeze or other system problems. The

AF24-SR (-S) US wired to either the SGA24 or SGF24 can be

used for minimum position setting and still provide full close-off.

Manual Override

The AF series actuators can be manually positioned to ease

installation or for emergency positioning.

tion shown by the

1. The manual override will only work if no power is available

to the actuator.

2. Insert the manual crank (shipped with the actuator) into

the hexagon hole located on either side of the actuator. An

illustration, located on the label, shows the location.

3. Turn the crank in the direction shown on the label (clock-

wise on the "CW" side, counterclockwise on the "CCW"

side). It will take approximately 19 revolutions to rotate

the full 95° of rotation.

4. To lock the actuator in the required position, rotate the

crank quickly in the opposite direction, 1/2 of a revolution. The

"lock closed" icon on the label shows the correct direction.

5. The manual override may be disengaged in 2 ways.

- Rotate the crank about a 1/4 revolution in the same

direction as the initial winding. The "lock open" icon

shows the correct direction.

- Apply power to wire 1 and 2. The actuator will automati-

cally disengage the override function and will go to the

"on" position in the case of the on-off versions. Or, in the

case of the proportional versions, go to the 0 signal posi-

tion and then go to the position corresponding to the

control signal. The actuator will now work normally.

Testing the installation Without Power

The actuator/damper installation may be tested without power

at the actuator. Refer to the manual positioning section of the

instructions. Move the damper to its full non-fail-safe position

using the manual crank. Disengage the manual position

mechanism and have the damper go to full fail-safe position.

Correct any mechanical problems and retest.

Auxiliary Switches

The AF series actuators may be ordered with 2 built-in SPDT

auxiliary switches used for safety interfacing or signalling, for

example, for fan start-up. The switch position near the fail-safe

position is fixed at 5°. The other is adjustable between 25 and

85° of rotation. The crank, supplied with the actuator, or a 3mm

allen wrench is used to adjust the switching position.

Switch Rating

Two methods may be used to adjust the switching point of the

adjustable switch.
