Thomson
4.6.9 Control option LLX
In addition to all of the features included in the LXX version (section 4.6.8), LLX also includes end of
stroke indication. These outputs can be used to provide feedback that the actuator has reached it's
mechanical minimum or maximum stroke.
Since these outputs 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.
