Depending on the actuator, adaptation is initiated by one of the following a) Pressing the manual override button twice b) clicking the CW/CCW switch twice c) pressing the adaptation button (SY's) d) pressing the power button for a few seconds then releasing it. When adaptation is initiated the actuator will drive one full cycle (0 to 100%) to its mechanical end stops or the valves travel limits.  Upon completion of this cycle the actuators working range (input, feedback and possibly run time) will be adapted to the actual mechanical angle of rotation or travel.
