Abstract: There is a growing number of Church buildings that acquire electronic bell ringing equipment which makes, it possible to automate the electronic ringing. However, most of current devices do not take into account the temperature conditions which leads to damage of bells. This study describes the approach to the construction of the Automated Management System (AMS) of sounders with high upgrading rate in the case of chime automated management system. The system has a web-based access mechanism. We have also developed the system’s self-tuning algorithm which implies execution of a series of test strikes. Specific attention is paid to the selection of the best parameters of the control signal, namely the period and duty factor of the Pulse-Width Modulation (PWM) which was chosen as a means of changing the DC motor speed and the rotation direction. The analysis of experimental studies showed that in order to achieve the loudest sound one needs to vary the period and the duty factor of PWM with regard to the environment. The proposed device has a self-tuning function which eliminates inaccuracies in operation related to the human factor.
