What micron size are you after?
I have a 35 micron profile for grey Wanhao D7 resin:

{
	"ProfileID": 30,
	"Title": "Wanhao D7 Grey 35 micron",
	"Desc": "",
	"ResinPrice": 99,
	"ZStepWait": 200,
	"SlowSectionHeight": 2,
	"SlowSectionStepWait": 150,
	"TopWait": 1.9,
	"WaitHeight": 6,
	"CureTime": 5,
	"DynamicWaitAfterLift": "",
	"DynamicCureTime": "",
	"DynamicSpeed": "",
	"DynamicLift": "",
	"Depth": 35,
	"WaitBeforePrint": 1.5,
	"WaitAfterPrint": 0.01,
	"JumpHeight": 0,
	"JumpPerLayer": 0,
	"SupportTopWait": 3.5,
	"SupportWaitHeight": 6,
	"SupportLayerNumber": 5,
	"SupportCureTime": 25,
	"SupportDepth": 35,
	"SupportWaitBeforePrint": 12,
	"SupportWaitAfterPrint": 3,
	"LowQualityCureTime": 12.6,
	"LowQualitySkipPerLayer": 0,
	"XYRes": 0,
	"XYResPerc": 0,
	"ZResPerc": 0,
	"FillColor": "#ffffff",
	"BlankColor": "#000000",
	"SyscallBeforeLayer": "",
	"ShieldBeforeLayer": "G1 Z[[LayerPosition]] F[[ZSpeed]] P1\r\n[[WaitForDoneMessage]]\r\n[[PositionSet [[LayerPosition]]]]",
	"SyscallAfterLayer": "",
	"ShieldAfterLayer": "G1 Z{[[LayerPosition]]+[[ZLiftDistance]]} F{[[ZSpeed]]/5} P1\r\n[[WaitForDoneMessage]]\r\n[[PositionSet [[LayerPosition]]]]",
	"PixelDiming": 0,
	"DimAmount": 0,
	"DimWall": 0,
	"DimSkip": 0,
	"HatchingType": 0,
	"HatchingWall": 0,
	"HatchingGap": 0,
	"HatchingOuterWall": 0,
	"HatchingTopCap": 0,
	"HatchingBottomCap": 0,
	"AntiAlias": 0,
	"ImageRotate": 0,
	"IgnoreMask": 0,
	"ShieldStart": "",
	"ShieldResume": "",
	"ShieldFinish": "",
	"Updated": 1522120758
}

You can get the figures out of the CWS software if you dig around,  I believe they are tested profiles so will somewhat get you a good print, but with such variation in UV Led's its always best to calibrate your printer against the resin.

Here are some more figures if you want a 50 micron layer height:
clone profile above, and adjust...
Burn-in layers -> layer thickness = 50
Burn-in layers -> Cure Time = 40

Normal layers -> layer thickness = 50
Normal layers -> Cure Time = 7

Larger layer heights more cure time, more viscous resins lift slower, clear, blue and green resins want longer cure times.

After install nanodlp i update to last stable vers.   And i can't find files with printer and resin profiles on SD Card. Where is ?

I print 80 micron layer.  On CW printing OK. 35 s on bottom layers and 7 s on other layers

If you did a manual install I dont think there is any configuration files.  You need to add all these.

Printer and machine files at the bottom here: https://3dprinterwiki.info/d7/d7-nanodlp-settings-2/
Some resin profiles: https://www.nanodlp.com/repo/

I understood my problem. The UV Light  is switched on immediately after the platform is lowered.
And only after" wait after lift " LCD shows the layer. But all this time the lighting is on and turns the polymer into a brick.
How do I turn on the backlight with the layer projection?

If I remember rightly the process is, platform lowered, UV led on shutter closed, shutter open while UV LED is on, cure time, shutter close UV LED off.  Visually you should see completely black screen, then a black screen with a hint of purple, then LCD shows layer with a very bright image, then it repeats.

Yes , that's right. At first, just lighting.
Then, highlight through the layer outline.
But in CW there is no moment when only the backlight without the screen is lit.
Maybe that's why I got an overlight? 
And how can the backlight be turned on with the screen? (After "waiting after lift')
