Hello yesterday i deleted my Grid, cause my Ui was too full^^, but now i miss the grid function to show me who is out of heal range or another range set, so that they have darker lifebars. A friend tell me theres the same function for XPerl, is that right. I cant found any option for that.

Answers could be in German to^^.

Es gibt im XPerl Menü eine Option die sich "Range Finder" nennt. Da machst n Häkchen rein und daneben den Spell der für deine Heilung zuständig ist wegen der Reichweite.
Daneben hast Du noch mal n Feld, mit dem Du den "Fade Amount" konfigurieren kannst. =) 

I believe Xperl, in terms of the unit frames (I don't use the raid frames) has a little hand icon if they are too far.  In terms of the raid frames, I don't know since I use Grid.

Yes, the answer is in german. The make it short, you'll find the setting in the 'Global Tab', at the bottom you'll find the option 'Range Finder'. That's the setting you need to look into and adjust to your own use.

My Xperl fades the toon in the raid panel. I have all raid party panels up, and the "lit" ones are in range for heals. I set it up a long time ago, but yeas, I believe it's the range finder and you can tell it to fade people that are out of range of heals.
