Device for signaling the operation conditions and the failures in a burner.

摘要

A device for showing the operation conditions of the failures in a burner comprising, in combination: an instrument for counting and visualizing the time (10) beginning from the moment in which the control and monitoring instrumentation gives the consent to start to the burner; a plurality of pilot lights (1-6), each of them indicating at least: the presence or the absence of the mains voltage (1); the operation or the failure of the burner motor (2); the operation or the failure of the burner (3); the operation or the failure of the first fuel valve of the burner (5); the operation or the failure of an eventual second fuel valve of the burner (4); the waiting condition or the failure of the control and monitoring instrumentation of the burner (6). According to a preferred embodiment the instrument for the time counting is a microprocessor (24) able to repeat the count at each consent to start given to the burner.
