Problem with generating a signal

Hi, I am trying to build/generate signal for control over modeled quadcopter.

I am using this scheme and scoped signal. http://www.upnito.sk/imggal.php?viewGallery=90dd7f49e60c2c3687a7a8c1ac3d5902

The second impulse just doesn't generate signal like a first one. Doesn't matter if impulse has positive value or negative.

Does anybody know, where or what can be a problem ?

sampling time in zero holder and unit delay is 0.5s

It looks like a problem with sample time.

Enable the sample time colors from the Format menu. This will help you to view at which rate you blocks run and configure them to behave as you expect.
