Follow the arrows from each box, answering YES or NO , to locate the fault. The
back cover may have to be removed and the main chassis placed in service position.

further information.
If measurements are needed, please refer to the chapter measurements, placed
behind #3 Fault fl ow chart .
When a voltage specifi cation is given in the fault fl ow chart, a value within ±10-20%
