A door system includes a controller for controlling the door system. A user computer system transmits information to the controller over a wireless connection to modify operating parameters for controlling the operation of the door system. During installation of the door system sensors may be utilized to determine if the door system has been installed properly. The sensors may be used to identify if the door system is mounted level and plum, and to review the movement, vibration, speed, acceleration, force, or the like of the sensors, and thus, the components to which the sensors are operatively coupled in order to make adjustments to the door assembly. Furthermore, the operating parameters of the installed door system, may be cloned and provided to other door systems in order to quickly clone and distribute the operating parameters of one or more door systems to one or more other door systems.

The aim of the invention is to achieve a door closer arrangement (1) where the force needed for opening the door (2) is not so substantial. The invention comprises a door closer (6), a slide rail (7), and an arm (8) that connects the door closer with the slide rail. The arrangement comprises also a second rail (9), which is arranged to form a slide slope for the door closer (6).

The invention relates to a braking mechanism (10) for a movable door wing (1) with an electric motor (14) operating as a generator, the at least one drive shaft of which can be rotated by a movement of the door wing (1), and at the terminals thereof, a movement-dependent output voltage is produced, which is applied to an evaluation and control unit (20), and a stop spring (12) which damps a manual opening movement of the door wing (1) between a predetermined opening angle and a maximum opening angle with a constant first damping, and a corresponding door with a braking mechanism of this type. In accordance with to the invention, the evaluation and control unit (20) performs a pulse width modulation (PWM) of the motor current cooperating with the output voltage and establishes an effective sequence of braking force, which generates a variable second damping of the opening movement of the door wing (1), so that the door wing (1), when released, stops upon reaching the maximum opening angle.
