MOTORS

63-2631—07

SETTINGS AND ADJUSTMENTS

Before Setting Stroke

Remove the top cover from the motor.

Disconnect the controller from the motor.

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:

Turn the

stroke and sensitivity

potentiometers fully

clockwise, using a 1/8 inch straight-blade screwdriver.

Turn the

remote

potentiometer (previously installed on

R-W-B terminals) to maximum position.

Turn the sensitivity potentiometer to the selected stroke

(between 90 and 160 degrees)

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

5. IF

the selected stroke is reached using the sensitivity

potentiometer, turn the

stroke

potentiometer counter-

clockwise

until the motor begins to move. Then

turn the

stroke

potentiometer clockwise

slightly to

have the position correspond to the sensitivity

potentiometer.

Make sure the minimum position is correct.

Setup for Non-Spring Return Series 90 Motors.

Adjustable timing for M9182D1023

The timing potentiometer (the second from the right, (Refer to
Fig. 10) sets the timing to 1minute, if turned fully CCW

, 2

minutes if turned to its middle point and 4 minutes if turned fully
CW .

CAUTION

Careless Installation Hazard.

Use of excessive force while adjusting cams

damages the motor.

To avoid damaging motor end switches, set cams by

moving only the top of the screwdriver.

CAUTION

Careless Installation Hazard.

Forcibly turning the motor shaft damages the gear

train and stroke limit contacts.

Never turn motor shaft manually (either 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.

Fig. 11. Terminals and Adjustments.

Auxiliary Switches

Adjustable cams actuate the auxiliary switches. These cams

can be set to actuate the switches at any angle within the

stroke of the motor. Select switch differential of 1° or 10°.

Motors with factory-added auxiliary switches are shipped in the

closed position (fully counterclockwise, as viewed from the

power end). Auxiliary cam default actuates the switches 30°

from full open with a 1° differential. With the motor in the closed

(fully counterclockwise) position, the auxiliary switch breaks

contacts R-B. Refer to Fig. 7 (or the auxiliary switch Instruction

Sheet) for auxiliary switch wiring.

NOTE: Auxiliary switches can only be added to motors

that include auxiliary switch cams. (These cams

cannot be field-added.)
