180° Rotation,

Center-Off Kit

FCD WCAIM2074-00 (Part 19530)

Installation, Operation and Maintenance

For 10-30 75 Electric Actuators

Installation

NOTE: This kit should not be used with actuators with extra limit

switches. To add a center-off kit to an actuator with more than two

switches, consult the factory. The differences for 75 DC actuators

are either in parentheses or stated separately.

I. Changing a 90° actuator to a 180° actuator

A. Verify 90° operation of the existing actuator.

1. Connect power to terminals 1 and 4 for AC (+ to 1 and

- to 4 for DC). The actuator will turn clockwise to the

initial zero position.

Limit switch #1 on the right side of the actuator (viewed

from the terminal strip) stops shaft rotation in the

clockwise direction (CW). This stop point is 0° and is

the position where a ball valve is closed.

The bottom cam on the actuator shaft (called the #1

cam) actuates this limit switch.

2. Connect power to terminals 1 and 3 for AC (- to 1 and +

to 3 for DC). The actuator shaft will turn counterclock-

wise (CCW).

Limit switch #2 on the left side of the actuator (viewed

from the terminal strip) stops shaft rotation in the

counterclockwise direction (CCW). This point is 90° and

is the position where a ball valve is open.

The top cam on the actuator shaft (called the #2 cam)

actuates this limit switch.

B. Adjusting actuator cams for 180° operation

1. Once proper operation of cams and switches for 90°

operation is veriﬁed: Adjust (see Step 2) the clockwise

cam (the bottom cam or #1 cam) so that the actuator

shaft can rotate 180°— ±90° from the initial zero (#1

limit switch) position.

2. Perform cam adjustment as follows:

a. Power actuator terminals 1 and 3 for AC (- to 1 and

+ to 3 for DC) to move the actuator shaft to its full

counterclockwise (CCW) position as established in

Step A2 of this procedure.

b. Loosen the set screws on the #1 cam and energize

terminals 1 and 4 for AC (+ to 1 and - to 4 for DC)

to move the actuator shaft clockwise (CW) a total of

180° to the new 0 position.

c. At this position, stop the actuator and adjust the #1

cam so that the limit switch (on right side of actua-

tor, viewed from terminal strip) is actuated. Listen

for click. Retighten set screws on the cam.

NOTE: To ensure full rotation of the driven device,

set the actuator cams so that an additional 2° of

rotation can be achieved at each end position.

d. Verify that the actuator moves 180° by energizing

terminals 1 and 3 for AC (- to 1 and + to 3 for DC)

(CCW) and terminals 1 and 4 for AC (+ to 1 and - to

4 for DC) (CW).

Remember: The only stop point now common to

the 90 degree actuator is the CCW limit—the posi-

tion where a 90° ball valve is open.
