Universal Sliding Gate Opener PCB Controller Board PY600ACL SL1500AC - Smart WiFi Control

Updated control PCB for sliding gate openers (see photo). This electronic card plate is used with PY600ACL and SL1500AC units and supports Smart WiFi Control. The board features four adjustable trimmers labeled VR1 through VR4 to fine-tune motor behavior: - VR1: Sets the motor running time. Turn clockwise to lengthen the run, turn counter-clockwise to shorten it. Adjustment range: minimum 10 seconds, maximum 90 seconds. - VR2: Adjusts the stopping force applied when the motor is coming to a stop. Clockwise increases the force; counter-clockwise reduces it. - VR3: Controls the soft-stop distance (operation distance for soft stop). Directional adjustment matches VR2: clockwise increases distance, counter-clockwise decreases it. - VR4: Alters motor torque output. Turn clockwise to raise torque, turn counter-clockwise to lower torque. All technical adjustments are made via the on-board potentiometers so you can calibrate runtime, stopping force, soft-stop distance, and torque to suit your installation.
