SETTINGS AND ADJUSTMENTS
Before Setting Stroke
1. Remove the top cover from the motor.
2. Disconnect the controller from the motor.
3. Connect a remote potentiometer to the motor as shown
in Fig. 6 (R-W-B).
The stroke adjustment on the series 2 and series 3 motors is
made using the stroke and sensitivity
potentiometers located
under the cove inside the motor. The stroke adjustment on a
series 1 motor was made by adjusting the CAMS.
For Series 2 and Series 3 Motors:
To set the stroke to 160 degrees (maximum position) turn both
stroke and sensitivity potentiometers fully clockwise ,
using a 1/8 inch straight-blade screwdriver.
To set the stroke to 90 degrees (minimum position) turn both
stroke and sensitivity potentiometers fully counter-clockwise
, using a 1/8 inch straight-blade screwdriver.
To set the stroke between 90 and 160 degrees:
1. Turn the stroke and sensitivity potentiometers fully
clockwise, using a 1/8 inch straight-blade screwdriver.
2. Turn the remote
potentiometer (previously installed on
R-W-B terminals) to maximum position.
3. Turn the sensitivity potentiometer to the selected stroke
(between 90 and 160 degrees) OR until the motor stops.
4. IF the motor stops before the selected stroke is reached,
turn the stroke
potentiometer until the selected stroke is
reached OR
5. IF the selected stroke is reached using the sentivity
potentiometer, turn the stroke
potentiometer counter-
clockwise until the motor begins to move. Then
turn the stroke
potentiomter clockwise slightly to
have the position correspond to the sensitiviity potenti-
ometer.
6. Make sure the minimum position is correct.

Forcibly turning the motor shaft damages the gear
train and stroke limit contacts.
Never turn motor shaft manually (by hand or with a
wrench).
CAUTION
Equipment Damage Hazard.
Can damage the motor beyond repair.
Set cams by moving the top of the screwdriver only.
Pressing screwdriver against cam slot sides or use of
excessive force can damage motor end switches.
