Programming Note: The above switch positions are the base programming configurations, in the base
configurations all other switches should be switched off . Once the base programming configuration has
been set up you may wish to add additional program features and functions that are listed below.

Note: This table shows the auxiliary switch action based on the dip switch 1 and 7 settings. You should program the dip switches on the actuator
based on the application requirements, once programmed review this chart to determine the action of the auxiliary switches and wire the switches
accordingly. IF YOU CHANGE EITHER DIP SWITCH 1 or 7 TO GET A DIFFERENT CONTACT CLOSURE YOU WILL CHANGE THE
EXTEND/RETEACT MOVEMENT OF THE ACTUATOR.
Note: With power to the actuator off, Auxiliary Switches are made KC1 to K1 and KC2 to K3. Upon power up switches will
make as shown above after auto start up calibration.

With the actuator powered and being controlled by the input signal the optional auxiliary switches only transfer contacts as follows,
driving from full retract to full extend the auxiliary contacts transfer when the actuator is about 95% of full extend travel. When the
actuator drives from full extend to full retract the contacts will transfer when the actuator is about 95% of full retract travel.
