Beschreibung
Zusammenfassung:	The device incorporates at least one light-reflecting element (11) placed over a portion of at least one conventional rotating element (10) of the timer, a light source (130), a system (140) for detecting and converting the light, two concentric optical fibres, one outer (21) and one inner (22), an amplifier to receive the electrical signal from the conversion system (140), a first comparator circuit to compare the amplified electrical signal with a first threshold (S1), a second comparator circuit to compare the amplified electrical signal with a second threshold (S2), an alarm or indicator device connected to the output of the first comparator circuit and a device (190) for counting and storage of the pulses delivered by the second comparator circuit.
