9-3. RESET CIRCUIT PART

RESET circuit part is performed the eariy state all program furction when input power and confimate power to MICOM for suddeniy electricity failure, it is initialed to PAM of inside MICOM. when confimate power RESET’S vltg is“LOW”state during sevweal tens uses and it is“HIGH”state as nomal operation state.

9-4. SENSING OF TEMP PART

SENSOR OPEN	SENSOR SHORT

Inpat MICOM“HIGH”	Inpat MICOM“LOW”

1)SENSOR is vsing the THER with labor coefficint, if temp. is high, resistance is low on the contrary if temp. is iow, reissitarce is high.

2)According to sensor, voltage of input to MICOM is calculate,

Vf =	Rth	X Vcc(Vcc:5V, Rth:SENSOR RESISTANCW)
	Rth + 10㏀
