Abstract

Improvements in supervisory circuits for electronic systems, the system of which comprises at least one operating chain provided with an input adapted to receive variable frequency input signals, a voltage frequency converter, a signal processing circuit and an utilization device, characterized by that said supervisory circuits comprise a switching circuit periodically activated by a signal generator to simultaneously control a delayed-action warning device and a delayed switching system in which the switching element is connected between ground and the input of the functional chain, creating the closure of said switching element a disturbance that causes the supply by the functional chain of a signal that energizes the device for use, said device being connected to the switching circuit to readjust it, said switching element remaining in closed position for a time or equal to or slightly greater than the response time of the functional chain, the action of said warning device being delayed for a time at least equal to the closing time of the switching element.
