Setting the pulse stretching

If the web speed is high and the splice width is thin, the signal on the switching
output is very short when moving over a splice.

– Therefore a fixed pulse stretching of 20 ms is activated in the factory set-

tings.

– If pulse stretching is undesirable, you can switch the function off.
