How to check double sheet module sensor sm 52-4

Machine sm 52-4 anicolor 2009
Cpc prinect center.
My printing shop start installation this macine and still can not running.
The problem is feeder button can not ON with one or more printing unit. But van ON with inching mode. Paper stop on feeder table and read as double sheet error.
Technician said i must change double sheet sensor (black box under feeder table).
The Reason he open on monitor diagnose menu analog In.
Value must change. In my monitor read as first analog input information
Double sheet detect pulling device OS
Status Stopped.
Value not change.

 

please sir can you be precise in your explanations? so that we can provide solutions? please picture of the problem on the machine screen and what you wanted to do thank you?

 

Well,
The double sheet detector reads at specific degree range, you should inch the machine (with feeder ON) till reach this degree, then you check the reading on the display.
Send me the machine number to inform you the degree.
I hope that you did not uninstall the old sensor!!

 

Machine serial number GS 000272.
Heidelberg techician can see data from number of machine ? Thanks a lot

 

In your machine, you have to open (actual values/double sheet datector) at service display.
Then you can find the reading on feeder display (in micrometers)
You have to login under service user.

 

Before i press feeder button no double sheet error. After i run paper. Paper stop on the feeder table and read as double sheet error ahown on monitor.
Technician said the value on mode analog in must be change. In my monitor value with double sheet sign always same not change.
Where i can see the value of feeder degree.
Thanks

You have to find some change in values during inching machine with feeder ON

Can you give more information standard value from heidelberg machine ?

Could you inch your machine (with feeder ON) and send me a video for this screen
