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
pushrod
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.

Not part of this kit, obtain separately.

These values represent the controller output voltage
required to drive the motors.
NOTE: Motors are shipped in the fully closed position (the
limit of counterclockwise rotation as viewed from the
power end of the motor) with the stroke set at
90”.

NOTES:
a
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.
b
Motors may operate in Series 90 or two-position control applications. However, checking voltage between terminals
R
to B and R to W is necessary to confirm proper operation in electronic (W973, 4 to 20
mA
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.
Checkto
see
whether or
not the mounting bracket is
needed.
lf
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).
4a.If
the bracket is not needed, mount the new actuator
directly to the equipment and refer to the INSTALLATION,
SETTlNGS&ADJUSTMENTS,andCHECKOUTsections
of these instructions as needed.
4b.ffthe
bracket is needed,
referto
the Adapter Bracket
sections and see Fig. 3 as well as the INSTALLATION,
SETTINGS &ADJUSTMENTS, and
CHECKOUTsections
of these instructions.
5. Use old mounting bolts to mount the new actuator.
6. Mountthedampercrankarmandlinkagetotheshaft
of the new actuator.
8. Use the CHECKOUT procedures to test the proper
adjustment of the crank arm and linkage.
