Sunload Sensor Inspection
1) Light over sunload sensor vertically with an
incandescent lamp of approximately 60 W. The
distance between sunload sensor and lamp should
be approximately 100 mm (3.94 in.).
2) Measure voltage between terminals of sunload
sensor as shown.
If check result is not satisfactory, replace sunload
sensor with new one.
Sunload sensor voltage specification
0.3 V or more
