Comments: This parameter is accessible only if previously in menu C9 delayed output pulse (C9
= on) and in menu C3 either dynamic dead time (C3 = 00) or fixed dead time (C3 =
02) was chosen.
A maximum of 10 further edges may occur between the end of an edge and the
delayed output pulse.
C11:
Pulse delay (mm) [Pulse Delay mm]
Input values: 0 to 999 in steps of 1 [100mm]
Function: to define the value of the output pulse delay in millimeters.
Comments: This parameter is accessible only if menu C9 delayed output pulse (C9 = on) and
menu C3 synchronous dead time (C3 = 01) were previously activated.
A maximum of 10 further edges may occur between the end of an edge and the
delayed output pulse.
C12:
Output pulse triggered by last edge [Out@PlsTrain]
Input values: 0 = first output pulse triggered by first edge of edge train
1 = last output pulse triggered by last edge of edge train
Function: to define whether the output pulse is triggered by the first or the last edge of a group
of multiple edges occurring within one dead time.
Comments: This parameter is accessible only if menu C9 delayed output pulse (C9 = on) and
menu C3 synchronous dead time (C3 = 01) were previously activated.
This parameter should be set to on if thick copies are processed and the Scatec is
used to trigger another action (for example: labeling) where as little jitter as possible
of the trigger point is required.
The following sketch shows the case where the fold of a thick newspaper breaks up
into two edges because of a slight indentation. The second edge falls within the
dead time triggered by the first edge. With parameter C12 set to 0=first, the output
pulse is triggered by the end of the first edge and the second edge is suppressed. If
parameter C12 is set to 1=last, the output pulse is initiated by the second edge while
it is the first edge which is suppressed. This way, it has been achieved that although
the fold is split up into two edges, it is still at the end of the fold where the output
pulse is initiated as if the fold would form only one continuous edge.
