CHECKOUT

After installation and linkage adjustment, check the entire
motor and control hookup to ensure that-
* The motor operates the damper or valve properly.
The motor responds properly to the controller.
l
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.
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".
