Abstract

Safety device for a microprocessor control system MP, in particular for the activation of an electric fan EV for cooling a combustion engine in a motor vehicle, in which the microprocessor MP periodically transmits pulsed signals to a monostable MS; in the event of damage to the microprocessor MP, the absence of pulsed signals causes the monostable MS to be deactivated, thereby activating the electric fan EV.
