Programming Notes: 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 programming

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/RETRACT 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.

Optional Auxiliary Switch Function (S2)
Example A Example B Example C
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.
