Low level electricity logic circuit partially goes through the optical coupling, so that the power supply is isolated. When the power supply fails, the output level electricity is down to the logic level. Adjust the output of trigger to turn off the circuit.
The response time of the circuit is 2m8. When AC voltage is normally over zero, there is no effect on the circuit. Power consumption of the circuit is 50mW.

Use former two out of 4011 CMOS’s 4 non-door to constitute a chopper oscillator. And use a 1MΩ potentiometer to change the duty cycle. If the third non-door is not connected, it is helpful to apply the input end of the fourth non-door into the integrated circuit (14). Before the power is turned, the potentiometer is firstly transferred to the middle position and then is regulated. In order to prolong the original battery life of 3 times, 50% duty cycle should be provided signal light with intermittent signal current and double voltage.

According to changes in light intensity, light current changes. When 3DG6 base injection current changes, the current in the collector circuit also changes after amplification. It would be reflected by the MA's meter bottom-up. And the meter reflects the light illumination.
When there is weak light, the base potential is close to 6V. 3DG6 is saturated to conduct, leading the collector current to fill the meter’s scale. When there is strong light, the base potential decreases to have a decreased injection current. And the collector current follows down to lead the meter to zero state. Darken photodiodes can make an mA full-scale meter by adjusting R1 and R3.
