PY600ACL / SL1500AC Sliding Gate Opener PCB Control Board — Smart WiFi Motor Controller

You will receive the updated control PCB as shown in the photos. The board features four adjustable trimmers (VR1–VR4) that let you fine-tune motor behavior: VR1 sets the motor run time — turn clockwise to lengthen the operating time and counter-clockwise to shorten it; adjustable between 10 seconds (minimum) and 90 seconds (maximum). VR2 controls the stopping force applied when the motor halts — clockwise increases the force and counter-clockwise reduces it. VR3 adjusts the distance for the soft-stop function (same adjustment direction as VR2: clockwise to increase, counter-clockwise to decrease). VR4 modifies motor torque output — turn clockwise to raise torque and turn counter-clockwise to lower it. The PCB is compatible with PY600ACL and SL1500AC sliding gate opener systems and is supplied as the revised version depicted in the listing images.
