This control units for automatic doors and gates allow to control one alternate current three-phase or single-phase motor at 230V or 400V.
It features obstacle detectors (anti-crush devices) and a braking system which reduces inertia during the stopping phase. It also features a series of functions that can be selected by dip-switches (mini-switches) and adjustments performed by trimmers.
This control unit is fitted with an obstacle detection system based on methods for controlling motor stress depending on the level of absorbed power. This technique is commonly known as “overload cut-out” and inverts or stops the manoeuvre depending on the programmed operating mode. In the control unit, the control system can work in two ways, “normal” or “intelligent”: - “normal” mode, the function is activated when the power absorbed by the motor reaches the threshold value set up with the force trimmer. - “intelligent” mode was developed to overcome this limit. This function adjusts the cut-in threshold set up with the trimmer by means of an intelligent feature which is able to tell the difference between slow variations caused by the above reasons and rapid variations caused by an obstacle.
The unit features a set of microswitches used to operate various functions so as to make the system more suitable to user needs and safer in various conditions of use. All the functions can be activated by moving the relative dip-switch to the “On” position and deactivated by moving them to “Off”
