Adjustments
Remove the cover of the CP-8X91-456. (See Figure-9.)
Start Point and Span
1. Connect power to the CP-8X91-456 and the actuator.
2. Connect the driving controller providing the input voltage.
3. Connect the electric actuator.
4. Apply the minimum voltage signal for the new range from the controller to the input
terminals.
5. Adjust the START POINT potentiometer so that the actuator slidewire drives to its
minimum signal limit.
6. Apply the maximum signal for the new range from the controller to the input terminals.
7. Adjust the SPAN potentiometer so that the actuator slidewire drives to its maximum
signal limit.
8. Reapply the maximum and minimum inputs and check the end points.
Hysteresis
Hysteresis is adjustable by potentiometer (see Figure-9) to a maximum of 0.5 Vdc. Do not
reduce the hysteresis so that the actuator oscillates.
