Description

5

AN7

IN

Used for initial balancing of the bridge circuit (absolute humidity sensor). This input
is an analog input terminal from the AH sensor circuit, and connected to the A/D
converter built into the LSI.

6

AN6

IN

AH sensor input.
This input is an analog input terminal from the AH sensor circuit, and connected to
the A/D converter built into the LSI.

7-9

AN5-AN3

IN

Heating constant compensation terminal.

10

AN2

IN

Input signal which communicates the door open/close information to LSI.

Door closed; "H" level signal(0V).
Door opened; "L" level signal(-5V).

11

AN1

IN

Input signal which communicates the damper open/close information to LSI.

Damper opened; "H" level signal(0V:GND).
Damper closed; "L" level signal(-5V).

12

AN0

IN

Temperature measurement input: OVEN THERMISTOR.
By inputting DC voltage corresponding to the temperature detected by the thermistor,
this input is converted into temperature by the A/D converter built into the LSI.

13

P55

OUT

Digit selection signal.
The relationship between digit signal and digit are as follows;

Digit signal

Digit

P03 .......................... 1st.

P02 ......................... 2nd.

P01 .......................... 3rd.

P00 .......................... 4th.

P37 .......................... 5th.

P36 ......................... 6th.

P35 ......................... 7th.

P55 ......................... 8th.

Normally, one pulse is output in every ß
period, and input to the grid of the Fluores-
cent Display.

14

P54

OUT

Oven lamp and turntable motor driving signal. (Square Waveform : 60Hz)
To turn on and off the shut-off relay(RY1).
The square waveform voltage is delivered to
the relay(RY1) driving circuit.

15

P53

OUT

Convection motor driving signal.
To turn on and off shut-off relay(RY5). "L"
level during CONVECTION; "H" level other-
wise.

16

P52

OUT

Cooling fan motor driving signal.
To turn on and off shut-off relay(RY6). "L"
level during both microwave and convection
cooking; "H" level otherwise.

17

P51

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.
