CHECKOUT

After installation and linkage adjustment, check the entire

motor and control hookup to ensure that-

* The motor operates the damper or valve properly.

l 

The motor responds properly to the controller.

Inspect the motor, linkage, and valve or damper to see

that all mechanical connections are correct and secure. In
damper installations, the 

 should not extend more

than a few inches past the ball joints. Check to see that
there is adequate clearance for the linkage to move
through its stroke without binding or striking other objects.

Check to see that cams operate the auxiliary switches,

if used, at the desired point of motor rotation.

required to drive the motors.

NOTE: Motors are shipped in the fully closed position (the

limit of counterclockwise rotation as viewed from the

NOTES:

 Ensure motor transformer is sized properly. If a common transformer is used to power multiple motors, ensure power

input is in phase with all motors.

 Motors may operate in Series 90 or two-position control applications. However, checking voltage between terminals

 to B and R to W is necessary to confirm proper operation in electronic (W973, 4 to 20 

 etc.) applications.

DAMPER APPLICATION

1. Turn off power and remove wiring from the old

actuator.

2. Remove crank arm from shaft of old actuator and

remove the old actuator.

3.

 see 

whether or 

not the mounting bracket is

needed.   the linkage can reach the lowershaft position of

the new actuator and if the crank arm has clearance for the

needed rotation, then the bracket is not needed. Use

220738A Adapter Bracket or 221455A crank arm if crank

arm must rotate through the bottom plane of the motor (for
damper applications).

 the bracket is not needed, mount the new actuator

directly to the equipment and refer to the INSTALLATION,
