Method for adjusting and controlling an actuating drive for a burner

Abstract

Before start-up of a burner, minimum and maximum actuating positions of an actuating drive are set by setting elements. During control of the actuating drive, an automatic firing mechanism receives from a position transducer position signals dependent on the actuating position of the actuating drive reached during operation. The automatic firing mechanism assigns to the minimum actuating position the position signal measured during the feedback of the minimum actuating position of the actuating drive, and assigns to the maximum actuating position of the actuating drive the position signal measured during the feedback of the maximum actuating position of the actuating drive. Using the position signals assigned to the minimum and maximum actuating positions, corresponding control parameters are determined for activating the minimum and maximum actuating positions, and the control parameters are stored.
