C14: Short pulse suppression [ShrtP.Suppr.]
Input values: 0 = off short edges are not suppressed
1 = on short pulses are suppressed
Function: to define whether short edges should be considered as interfering edges and be
suppressed (1 = on) or not (0 =off). An edge is short if its duration is shorther than
25% of the mean edge duration.
Comments: This parameter is accessible only if menu C2 False pulse suppression was
previously activated (C2 = on).
The duration of an edge can be a characteristic which clearly shows whether an
edge should be suppressed or not. For example: thick newspapers will always
generate long edges, so that a rather short edge within many long edges will most
likely be an edge caused by some imperfections on the newspaper. With C14 short
pulse suppression activated (C14 = on), edges with a duration of less than 25% of
the mean edge duration will be suppressed. The mean edge duration is continuously
calculated by the sensor and adapted to the conveyor speed.
Short pulse suppression works properly only if the running direction is leading!
C15:
Sensitivity mode [Sensvty Mode]
Input values: 0 = stand standard
1 = custm customized
Function: to define whether one of the standard sensitivity levels defined in C16 will be
activated or if the sensitivity level will be set specifically by the customer in C17 and
C18.
Comments: A sensitivity level other than standard should be choosen only if the signals can be
controlled by the application software ScaDiag.
C16:
Sensitivity setting [Sensvt Settg]
Input values: 01 = high highest sensitivity
02 = mid medium sensitivity
03 = low low sensitivity
04 = v. low very low sensitivity
Function: to define the actual sensitivity of the sensor.
Comments: This parameter is accessible only if previously in menu C15 standard sensitivity
mode was activated (C15 = 0).
Paper sheets of at least 0.1 mm thick will be detected with the Scatec-10 set to its
highest sensitivity and mounted at a distance of 68mm to 72mm. The Scatec-15 set
to the highest sensitivity will detect sheets 0.15mm thick and larger at a distance of
97mm to 103mm. However, if set to the highest sensitivity, folds or wrinkles could
cause interfering edges. If the edges to be detected are thick enough, than it might
be an advantage to reduce the sensitivity to become less sensitive to interferences.
Note: The sensitivity is dependant on the working distance. Please refer to the
diagram in section 11.7 Application data.
