B. Operation panel section

(1) General

The operation circuit is composed of the display matrix circuit and the
key matrix circuit.

LED

display:

Turns on each LED with DSEG0

∼

DSEG7 and

MDL0

∼

MDL4 signals.

By turning on/off signals DSEG0

∼

DSEG7 according to timing of

MDL0

∼

MDL4, the LED display at the intersection point of matrix is

turned on.

Key

detection:

Key detection is made by the signal matrix of
DSEG0

∼

DSEG7 and K10

∼

K11.

When all the MDL signals are off during switching of the MDL signals,
DSEG0

∼

DSEG7 are selected. By turning on the transistor at the last

step in the main PWB when the key is pressed, the input state of K10
or K11 is judged to detect ON/OFF of the key.

For selection of DSEG, two signals are switched at one time during
MDL is off.

(2) Display circuit section

This circuit is controlled by the data signal and the control signal from
the main control signal.

C. DC power operational description

(1) General

When the specified AC input is applied to this power, two DC vol-
tages of +24V (VB) and +14V (V8S) are provided. (V8S is made to
BV stabilization power by the 3-terminal regulator in the main PWB.)

The DC power employs the pseudo-resonance self-excitement
flyback convertor system with the hybrid IC STR-F6514 (100V series)
and STR-F6523 (200V series).

Fig. 1 shows the block diagram of the power section.
