I/O
Terminal not used.
Oven lamp and Fan motor driving signal.
To turn on and off the shut off relay(RY1). The square waveform voltage is delivered to
the RY1 driving circuit and RY2 control circuit.
Magnetron high-voltage circuit driving signal.
To turn on and off the cook
relay(RY2). In P-HI operation, the
signals holds "L" level during mi-
crowave cooking and "H" level
while not cooking. In other cook-
ing modes (P-90,P-80,P-70,P-
60,P-50,P-40,P-30,P-20,P-10,P-
0) the signal turns to "H" level and
"L" level in repetition according to
the power level.
Hood motor driving signal.
To turn on and off relay(RY4). "L" level: During
Hood motor ON. "H" level: During Hood motor
OFF.
Hood motor high / low driving signal.
To turn on and off relay(RY5). "L" level: During
Hood motor high. "H" level: During Hood motor
low.
Hood lamp driving signal.
To turn on and off solid state relay(SSR1). " 1 "
level: During Hood lamp ON (WORK LIGHT level).
"
2
" level: During Hood lamp ON (NIGHT
LIGHT level). "H" level: During Hood lamp OFF.
Turntable motor driving signal.
To turn on and off relay(RY3). "L" level: During
Turntable ON. "H" level: During Turntable OFF or
during the oven is off condition.
Terminal not used.
Used for initial balancing of the bridge circuit (absolute humidity sensor)
