Convection motor driving signal.
To turn on and off shut-off relay(RY7). "L" level during
CONVECTION; "H" level otherwise.
Hood lamp driving signal.
To turn on and off relay(RY8). "L" level: During Hood
lamp ON. "H" level: During Hood lamp OFF.
Hood motor driving signal.
To turn on and off relay(RY9). "L" level: During Hood
motor ON. "H" level: During Hood motor OFF.
Hood motor high / low driving signal.
To turn on and off relay(RY10). "L" level: During Hood
motor high. "H" level: During Hood motor low.
Timing signal output terminal for temperature measurement(OVEN).
"L" level (GND): Thermistor OPEN timing.
"H" level (-5V): Temperature measuring timing. (Convection cooking)
Signal to sound buzzer.
A: key touch sound.
B: Completion sound.
C: When the temperature of the oven cavity reaches
the preset temperature in the preheating mode, or
when the preheating hold time (30 minutes) is elapsed.
Input signal which communicates the damper open/close information to LSI.
Damper opened; "L" level signal(0V:GND).
Damper closed; "H" level signal(-5V).
Signal to synchronize LSI with commercial power source freqency.
This is the basic timing for all real time processing of LSI.
Connected to VC.
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is applied. Temporarily set
to "L" level the moment power is applied, at this time the LSI is reset. Thereafter set at
"H" level.
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 micro-
wave cooking and "H" level while
not cooking. In other cooking 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.
Heating element driving signal.
To turn on and off shut-off relay(RY3). "L" level during convection cooking; "H" level
otherwise. During convection cooking, the signal becomes
"H" level when the temperature of the oven cavity exceeds
the predetermined temperature.
Internal clock oscillation frequency setting input.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with
respect to XOUT terminal.
