” level or “L” level, a CPU with a comparative judgment function equipped with a reset terminal, a memory to store the data of the CPU, and a backup to retain the contents of the memory in the event of a power outage. circuit, a power outage detection circuit that detects a power outage in the commercial power supply and issues a signal to the input terminal, and a CPU that starts operating the CPU when the power outage is restored.
It consists of a reset circuit that issues a reset signal to the reset terminal of the U, and a DC power supply circuit that supplies voltage and current to these circuits. The CPU determines whether it is a normal power outage that is a long period of time, and in the case of a momentary power outage, it operates as if there had been no power outage, and in the case of a normal power outage, the content of the work before the power outage is retained in memory and the power outage is recovered. A power outage processing circuit configured to operate according to a regular sequence.
