The second sensor SS2 is configured to output the second output OP2 in the second sensing interval T6 in the second state. The second sensor SS2 is configured not to output the second output OP2 in the first state.

The additional electronic controller circuit system EC3 is configured to change the state of the additional electronic controller circuit system EC3 from the first state S31 to the OFF state S30 if the sensed output voltage V1 is lower than the voltage threshold THV in the first state S31.

[0233] The first communicator circuitry WC1 is configured to be in the OFF state S10 when the additional electrical device ED3 is electrically connected to the electrical device ED1 via the cable CB1 and the additional electronic controller circuitry EC3 is in the OFF state S30 because the additional electrical device ED3 stops supplying power to the electrical device ED1 in the OFF state S30 .

The third state S13 and the fourth state S14 are repeated at the first interval T1 in the first state S11. The third state S13 and the fourth state S14 are repeated at the second interval T2 in the second state S12.

[0239] The third state S13 has a third time period T3. The fourth state S14 has a fourth time period T4. In the present embodiment, the fourth time period T4 is equal to the third time period T3. The third time period T3 is shorter than the first interval T1. The fourth time period T4 is shorter than the second interval T2.
