OUT
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 microwave 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.
OUT
Damper motor relay driving signal.
To turn on and off shut-off relay(RY4).
OUT
Heating element driving signal.
To turn on and off shut-off relay(RY3). "L" level
during convection cooking; "H" level otherwise. Dur-
ing convection cooking, the signal becomes "H" level
when the temperature of the oven cavity exceeds the
predetermined temperature.
OUT
Terminal not used.
OUT
Timing signal output terminal for temperature measurement(OVEN THERMIS-
TOR).
"H" level (GND) : Thermistor OPEN timing.
"L" level (-5V) : Temperature measuring timing.(Convection cooking)
OUT
Signal to sound buzzer.
A: key touch sound.
B: Completion sound.
C: When the temperature of the oven cav-
ity reaches the preset temperature in
the preheating mode, or when the
preheating hold time (30 minutes) is
elapsed.
OUT
Timing signal output terminal for temperature measurement(OVEN).
"H" level (GND) : Thermistor OPEN timing.
"L" level (-5V) : Temperature measuring timing.(Convection cooking)
IN
Signal to synchronize LSI with commercial power source frequency.
This is the basic timing for all real time
processing of LSI.
IN
Connected to GND.
IN
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.
OUT
Terminal not used.
IN
Internal clock oscillation frequency setting input.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with
respect to XOUT terminal.
OUT
Internal clock oscillation frequency control output.
Output to control oscillation input of XIN.
IN
Power source voltage: -5V.
VC voltage of power source circuit input.
