3, AC motor starting capacitor (CBB61, 1.5uF, 500V AC);
4, Relay for control AC power of output part, the designator is "K1" on the board;
5, AC output simulation LEDs, the function is identical with AC output;
6, Key array for setting the platform;

5.3 Test unexpected power down recovery function

For testing the unexpected power down recovery function of the platform, the platform reset circuit
need to be reworked. It's recommend to use RC reset circuit instead of the platform implemented
circuit because there is a power drop (nearly 1v) between "+5V" and Reset "high" Level, which
make Vdet0, Vdet1 and Vdet2 cannot work normally.
Below figure shows the RC reset circuit connection, the recommended RC value is 30K-100K
resister and 104 capacitor. Please rework the reset circuit with below RC reset circuit.
