4.6.4 Control option XXX
Utilizing the internal control system the actuator will:
• Stop the actuator immeditately at each end of mechanical travel.
To extend the actuator apply +Vdc to red and -Vdc to black. To retract apply -Vdc to red and +Vdc to black.
4.6.5 Control option XXP
Control option XXP works as option XXX (section 4.6.4) but also has an analog (potentiometer) output
that will provide feedback on the extension tube position.
To extend the actuator apply +Vdc to red and -Vdc to black. To retract apply -Vdc to black and +Vdc to red.
