Hi Carlos,
thanx for support.
Unfortunately problem is still the same.
Only 2 postitions are known…
If I try to make autocalibration the shutter works in a loop…. up-down-up-down-up-down.
I can stop only by pressing S1 and S2 the same time….
Pressing B-Button blue and a short pressing again makes the same (wrong?) calibration.
Auto-Calibration with pulsestation makes the same (wrong?) calibration.
I already delete the shutter eprom some times (B-Button yellow and short pressing again), but no chance.
Any idea or shutter is defect?
