Recovery flowchart (2-1)...Changing the VOL YNOFS3 setting voltage
[From the main flowchart (2)]
Set VOL YNOFS1 to the tentative setting value plus 15. / [VY1 ∗∗∗]
Set VOL YNOFS3 to the current setting value minus 2. / [VY3 ∗∗∗]
Replacement of abnormal circuits or
re-replacement of the panel required
No

Is the current VOL YNOFS3 setting value
samller than the tentative setting value?
Note: Disregard the discharge that may appear during
voltage-change setting.
No
Determine the current setting value for VOL YNOFS3 as the final value.
Determine the current setting value for VOL YNOFS4 as the final value.
Determine the current setting value for VOL YNOFS1 as the final value.
Set VOL YNOFS4 to the current setting value minus 2. / [VY4 ∗∗∗]
Set VOL YNOFS3 to the current setting value minus 15. / [VY3 ∗∗∗]
Set VOL YNOFS4 to the current setting value minus 15. / [VY4 ∗∗∗]
Set VOL YNOFS1 to the current setting value minus 15. / [VY1 ∗∗∗]
Set VOL YNOFS1 to the current setting value minus 2. / [VY1 ∗∗∗]
[To the main flowchart (2)]
Is there erroneous discharge (abnormal lit cell)?
