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

You will receive the updated control board as shown in the photo. The board includes four adjustable VR controls: VR1 sets the motor run time — turn clockwise to lengthen the run, counter-clockwise to shorten it (range: 10 to 90 seconds). VR2 controls the stop force of the motor; rotating clockwise increases the force and rotating counter-clockwise reduces it. VR3 determines the soft-stop distance and uses the same adjustment direction as VR2 (clockwise to increase, counter-clockwise to decrease). VR4 adjusts the motor torque output — clockwise raises torque, while turning it the other way lowers torque.
