8. CIRCUIT OPERATING THEORY

1) Power is on and makes about DC 300V through BD1.

2) TOP S/W is switching the best condition automatically.

Electric current run between D and S of TOP S/W and occur electric current in TRANS and when power of D-s is

off storing electric current of TRANS pass to secondary voltage.

3) Voltage main 12V. This is applied to display, relay and 5V power of sourcr and Main PCB

1) Tish needs function for CLOCK occurrence and time calculation.

In case of SPEC of RESONATOR change abnormal mode run because of changing Timming system of MICOM.
