6.2 Adjustment of the Sensor Voltage
1. Remove the top cover ASSY. (See 5.1.)
2. Turn No. 8 of the DIP switch on the BA01 board to the ON position and turn the power
switch ON.
* When turning the DIP switch to the ON or OFF position, slide the switch without loading
the circuit board. If not, a failure may occur.
3. Adjust the voltage of the chart and mask sensors as follows.
[Voltage adjustment of the chart sensor]
1) Measure the voltage between
TP1
and
TP3
on the BA01 board. Check that this voltage is
within the applicable range as follows. If it is not, make the voltage within the applicable
range by displacing the chart sensor.
[Applicable range: 4.5 V to 5.0 V]
2) Press the
VA DOWN botton
on the remote control twice and the
VA UP button
once.
3) Measure the voltage between
TP1
and
TP3
on the BA01 board. Check that this voltage is
within the applicable range as follows. If it is not, make the voltage within the applicable
range by displacing the chart sensor.
[Applicable range: 0.5 V or less]
4) Press the
VA UP button
on the remote control once. Check that the voltage between
TP1
and
TP3
is
4.5 V to 5.0 V.
[Voltage adjustment of the mask sensor]
1) Measure the voltage between
TP2
and
TP3
on the BA01 board. Check that this voltage is
within the applicable range as follows. If it is not, make the voltage within the applicable
range by displacing the mask sensor.
[Applicable range: 4.5 V to 5.0 V]
2) Press the
START botton
on the remote control twice and the
NEXT button
once.
3) Measure the voltage between
TP2
and
TP3
on the BA01 board. Check that this voltage is
within the applicable range as follows. If it is not, make the voltage within the applicable
range by displacing the chart sensor.
[Applicable range: 0.5 V or less]
4) Press the
NEXT button
on the remote control once. Check that the voltage between
TP2
and
TP3
is
4.5 V to 5.0 V.
Guide: When the voltage is higher than the applicable range, bring the sensor close to the
shading plate. When it is lower, locate the shading plate away from the sensor.
4. Turn No. 8 of the DIP switch to the OFF position, remount the top cover ASSY and
then turn the power switch OFF and ON.
