Limit Switch 

The counterclockwise limit switch is factory set to stop the 

actuator after 90° of travel. This setting can be changed in the 

field. To adjust the limit switch, removing the top metal cover, 

and locate the small opening next to the terminal block and 

positioned 

between terminals 3 and 4 . Insert a flathead 

screwdriver through this opening and turn the cam clockwise 

as seen from the shaft end of the actuator to increase the 

degree of actuator rotation up to a maximum of 320°. Each 

click of the cam represents about 3° change in actuator ro-

tation. Attempting to adjust for more than 320° rotation will 

result in both limit switches opening in the clockwise end of 

the actuator rotation, and the unit will no longer operate. The 

clockwise limit switch is fixed and cannot be field adjusted. 

Auxiliary Switch  

An adjustable cam operated SPDT switch is built into each 

actuator. The switch is factory set to operate at the clockwise 

end of the actuator rotation, making terminal 1 to terminal 6. 

As the cam turns counterclockwise from this point, the cam 

follower drops, breaking 1 to 6 and making 1 to 5. To adjust 

the auxilary switch, removing the top metal cover, and locate 

the small opening next to the terminal block and positioned 

next to terminal 1. Insert a flathead screwdriver through this 

opening and turning the disc clockwise as seen from shaft 

end of the actuator causes the switch to operate nearer the 

counterclockwise end of actuator rotation. Each click of the 

cam represents about 3° change in operating point. NOTE:  

After turning the disc, remove back plate and reposition the 

wiper; it will need to be repositioned back to zero. 

Speed Adjustment 

Actuator timing is varied by a slotted adjustment screw on 

the lower left side of the shaft (Models 424 & 454 only) 

housing. Turning the screw clockwise decreases the speed. 

If the adjustment screw is turned too far clockwise, the motor 

will stall but will not be damaged. If stalling occurs, turn the 

screw counterclockwise until the motor resumes operation. 

Total adjustment is normally 3 - 1/2 turns.

Adjustment (Preparation) 

From 

the factory, the actuator is calibrated such that it drives to 90 

degrees with 20 mA applied and 0 degrees with 4 mA applied. 

To reduce the 90 degree position or increase 0 degree posi-

tion, following the procedure below.

Initial Setup

1. Turn off all power and input signals to the actuator.

2. Remove the metal cover. This allows access to the poten-

tiometers and the input/deadband jumpers.

3. Disconnect the drive’s yellow and blue leads from the 

controller. 

4. Connect the drive’s leads to the corresponding lead on 

an instrument capable of producing 4 - 20mA +/- 0.1 mA 

(current calibrator).

Minimum Position Calibration

1.  Apply power to the actuator, then turn on the “current cali-

brator”.

2. Adjust the “current calibrator” until the mA input equals the 

desired zero point current. This is typically 4 mA.

See page 6 “Potentiometer Adjustment” for location of pots.
