Yesterday was fixing Centurion Vantage motors. It was big metal frame and mesh industrial double swing gate. Each leaf was longer than 3 meters, and it was suggested to the customer to install magnetic lock. But the customer decided to leave it as it is. The gate sometimes reached the end stopper and bounced back. I thought that something wrong with the sensor inside the motor. I passed one motor to the supplier. They found that the motor has worn out brakes.
Conclusion. If the Centurion Vantage motor installed on a long leaf gate without the magnet, first thing to check is brake.
