If a Parklio Gate begins to open and close uncontrollably after a period of normal operation, the most common causes are either the photocells or the Gate configuration itself.

In most cases, the first step is to check whether the photocells are working properly. It is also important to inspect the batteries inside the photocells, as weak or empty batteries may lead to unstable performance or false signals. Another possible cause is direct sunlight affecting the photocells. This is often easiest to recognize when the barrier behaves uncontrollably only during a specific part of the day. Strong sunlight can interfere with the photocell signal and trigger unintended barrier movements. You can check the photocells wiring on the link below:

If the photocells and their batteries are found to be in good condition, but the issue still persists, the next step is to calibrate the Gate. Incorrect settings or a loss of calibration can sometimes cause the Gate to behave irregularly. Calibration helps the system correctly recognize the Gate’s movement limits and restore normal operation. To calibrate the Gate follow the instructions on the link below:
