Proposal:	
Proposal to correct graphical symbol position

Reason:	This CR introduce new graphical symbol for photodiode which replace old S00685. Also this CR modify application note A00042 for light direction presented by arrows. Proposed new symbol is presented with variant A position and direction of arrows present light to photodiode.

During the preparation of this proposal MT 60617 was consulted

APPLICATION NOTE	

Note identity number:	
A00042	
Status:	
Standard 	
Note type:	Rule			

Note (EN):

"If source and target are shown, the arrows shall point from source to target.

If there is a target but no specific source shown, the arrows shall point downwards and to the right.

If there is no specific target shown, the arrows shall point upwards and to the right.

These rules are applied for the original combination of the symbol in the 60617 database which means "Variant A" described in ISO 81714-1. For the other variants, the arrows rotate together with the other elements to keep the position in the whole combination of "Variant A"

Applies to: S00127, S00128, S00129, S00901, S01919, S01920
