DESCRIPTION OF LSI
I/O
IN
Connected to VC.
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.
Memory (EEPROM) data input/output.
Memory (EEPROM) clock out.
IN
Internal clock oscillation frequency input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit
with respect to XIN terminal.
Internal clock oscillation frequency control output.
Output to control oscillation input of XOUT.
IN
Power source voltage: -5V.
VC voltage of power source circuit input.
Grill (TOP) heating element driving signal.
To turn on and off the grill heating
element relay (RY3). "L" level during
grill cooking, convection cooking or
dual cooking, "H" level otherwise.
The heater relay turns on and off
within a 48 second time base in
accordance with the special program
in LSI.
Convection heating element driving signal.
To turn on and off the relay (RY4). "L"
level during grill cooking, convection
cooking or dual cooking, "H" level
otherwise.
The heater relay turns on and off within
a 48 second time base in accordance
with the special program in LSI.
Oven lamp and turntable motor driving signal(Square Waveform : 50Hz).
To turn on and off shut-off relay (RY1). The
square waveform voltage is delivered to the
relay (RY1) driving circuit.
Convection motor driving signal.
To turn on and off shut-off relay(RY7). "L"
level during convection or dual cooking "H"
level otherwise. (Relay RY7 does not turn on
at preheating mode.)
Fan motor driving signal.
To turn on and off the fan motor relay RY6. "L"
level during cooking, or for 5 minutes after grill
cooking or for a while after convection or dual
cooking. "H" level otherwise.
Terminal not used.
Damper motor relay driving signal.
To turn on and off shut-off relay (RY8).
Touch control transformer driving signal.
To turn on and off the shut off relay (RY5). If the oven has not been used for more
than 2 minutes, the relay RY5 will be turned off. The relay RY5 will be turned on
when the oven door is opened and closed.
