1. DC Power Supply Circuit
In addition to the DC power supply circuit, the bias circuit
and the heater lamp control circuit are contained in the DC
power supply PWB.
(1) Signal name vs output voltage
GND
: OV
vVD1
:
+5V (LSI and IC supply power)
vc
:
+10V (IC supply power)
AL
: Heater lamp control signal. The low state (OV)
of the signal makes the heater lamp activated.
FW
All wave rectified waveform

About 17V
VB
:
+24V (Solenoid and lamp supply power)
VH1,VH2:
About 30V
(High voltage transformer supply
power)
BS
Bias control
signal. Low state (OV) of the
signal outputs the bias voltage (230 + 10V).
BIAS
:
Bias output (230 + 10V).
