4.6.11 Control option LLP
In addition to all of the features included in the LLX version (section 4.6.9), LXP also includes a
potentiometer providing a voltage signal for the customer to use to determine position, speed and
direction.
The end-of-stroke indication ouputs are current sinking open collector type of outputs, they will each
require an external pull-up resistor to operate effectively.
Power the actuator by connecting red to + Vdc and black to - Vdc in the power cable. To extend the
actuator apply +Vdc to violet and to retract apply +Vdc to orange in the signal cable while applying - Vdc
to grey.
