<p>In a device (1) having connections means for applying a direct voltage (DCV) and having undervoltage detection means (31) a control voltage (CV) having two different direct voltage values (V5, V6) can be applied via the connection means (2) and the undervoltage detection means (3) can generate a detection signal (DS) which alternates between two different values (V1, V2) similarly to the two direct voltage values (V5, V6), transition detection means (58) being realized by processor means (16), which transition detection means are adapted to detect transitions (TR) between the two values (V1, V2) of the detection signal (DS) and by which at least one given program sequence can be started in the processor means (16) upon a detection of such transitions (TR).</p> |
