SETTINGS AND ADJUSTMENTS
Stroke Setting
On adjustable stroke motors, the stroke is field adjustable and
can be set between 90° and 160°. A mechanical adjustment
(cam) establishes the fully open (clockwise, viewed from the
power end) and fully closed positions of the motor shaft
(see Fig. 2). TRADELINE motors are factory set for 160°.
IMPORTANT
— Detach linkage from motor before adjusting stroke.
— Instructions are for normally closed models. Reverse
for normally open.
Before Setting Stroke
1. Remove top cover from motor.
2. Disconnect controller from motor.
