1 Safety information The laser diode installed in the Scatec-10 / -15 emits visible red light. This laser belongs to the Class 2 laser standard specified by the IEC 60825-1 / 2007. Avoid looking directly into the beam for long periods. Brief irradiation of the eye (0.25 sec) that can occur during an accidental glance is not regarded to be dangerous. However, the laser should not be aimed deliberately at people. The laser beam should also be blocked at the end of its intended path.
3 Introduction As a member of the Scatec family, the Scatec-10 / -15 generally provides a means of detecting object edges. These sensors are best suited for non-contact counting of overlapping paper sheets and newspapers in the printing industry. If an object with an edge facing the laser beam passes through the beam, the sensor reacts with an electrical output pulse.
4 Principle of operation Described simply, the SCATEC-10 / -15 consists of a laser light source and two photo detectors. The beam is aimed diagonally at the objects to be detected. The photodetectors V and R detect laser light scattered by an object in the forward and backward direction, respectively. The ratio of light received by these two detectors differs widely depending on whether the beam strikes a flat surface or an edge.

6 Terms and definitions Scatec-1x Running direction h d a k Conveying plane Front edge Beam blocker Tail edge Interfering edge Mounting height h Distance between the lower edge of the sensor and the conveying plane. Working distance d Distance between the lower edge of the sensor and the plane where the edge lies on. Note that the working distance equals the mounting height only if the edge lies directly on the conveying plane.
7 Signal sequence The yellow edge indicator LED lights as long as the laser beam strikes an edge. The end of an edge (amber edge LED turns off) triggers the output pulse and the dead time. The dead time starts immediately with the trigger, while the delivery of the output pulse can be delayed (pulse delay adjustable by the customer). During the dead time, SCATEC-10 /-15 is inactive, i.e. an edge ending during the dead time will not initiate an output pulse and is therefore suppressed.
8 Installation 8.1 Electrical connection Make the electrical connections as specified in Sections 11.2 Electrical data, 11.3 Pin assignment, and 11.6 Wiring instructions. 8.2 Mounting (1) Scatec-10: Mount the sensor at a mounting height h of 70 +/-2mm above or below the conveying plane with the front windows parallel (+/-3°) to the conveying plane.
8.3 Beam blocker Uncontrolled reflections of the laser beam can cause malfunctioning of the sensor or disturb people. Therefore, a beam blocker should be fitted whenever possible to block the beam when there is no target present. A beam blocker is a flat surface (at least 25mm x 25mm) made of any matte non-reflecting material. It is mounted parallel to the sensor at any convenient distance. The amber edge-LED must not light while the laser beam hits a beam blocker! 8.
8.5 Cleaning the front windows Fingerprints, dust and other forms of dirt on the front window can impair the function of the sensor. It is normally sufficient to wipe the glass pane dry with a clean (!), soft cloth. Alcohol may be used for heavier soiling. 9 Setting the operational parameters Various parameters allow the customer to fully adjust the Scatec-10 / -15 to the specific demands of the actual application.
Flow chart for setting the operational parameters C Parameters C0 Pulse Length [msec] value 10.
9.1 Explanations on the operational parameters Default values are either the underlined input values or the input value in [square brackets]. C0: Input values: Function: Comments: Pulse Length [Pulse Length] 0.3ms – 99.9ms in increments of 0.1ms [10ms] to set the duration of an output pulse On the one hand, the duration of an output pulse must be long enough so that the customer’s control system can process it. On the other hand, the length of the output pulse limits the maximum counting rate.
A helpful rule of thumb is: Output pulse length p in milliseconds must be shorter than 1.2 million divided by the intended production rate given in copies per hour Example: production rate: 130,000 copies/hour resulting maximum output pulse length: 1,200,000 / 130,000 = 9.2 This relation is represented by the solid line in the diagram above. The theoretical value (dashed line) represents the case where the interval between copies becomes equal to the length of an output pulse.
C2: Input values: Function: Comments: C3: Input values: Function: Comments: False pulse suppression [FP-Suppress.] 0 = off no false pulse suppression mode will be activated 1 = on a false pulse suppression mode as defined in C3 will be activated To specify whether or not any kind of false pulse suppression mode will be activated. The specific mode of the false pulse suppression will be defined in menu C3. Suppression mode [Suppr.
There are three different types of dead time depending on how the dead time is specified. Dynamic dead time (00 = dyn): The length of the dead time corresponds to a certain percentage of the mean interval between copies. If dynamic dead time is set as the suppression mode, then the percentage will be set subsequentely in menu C4 (dead time %) .
tape, an output pulse is generated. This mode makes it possible to reliably count copies as long as each copy is preceded by a gap. The advantage of reacting solely to the retro-reflective tape is, that copies may have a surface and form of any kind, even heavily wrinkled (such as thick newspapers in a bag), without causing any false pulses, because the sensor does not react to edges in this mode.
ScaDiag would display the warning “conveyor in reverse”. C8: Input values: Function: Comments: Dead time (msec) [Dead time ms] 0 to 999 in steps of 1 [20ms] to define the dead time as fixed value in milliseconds. This parameter is accessible only if previously in menu C3 fixed dead time (C3 = 02) was activated.
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: Input values: Function: Comments: Pulse delay (mm) [Pulse Delay mm] 0 to 999 in steps of 1 [100mm] to define the value of the output pulse delay in millimeters.
C13: Input values: Function: Comments: Tail edge suppression [Tail Suppr.] edge suppressed if it is followed by a retro-reflective foil within the 0 = stand dead time 1 = extnd edge suppressed if it is followed by a retro-reflective foil within the output pulse delay time to define whether the area checked for tail edges extends for a dead time (0 = stand) or for an output pulse delay time (1 = extnd). This parameter is accessible only if menu C9 delayed output pulse (C9 = on) was previously activated.
Copy length Overlap Tail edge suppression zone Dead time Running direction Laser beam Retro-reflective foil Interfering edges set C9 Output pulse delay to 1 = on is the intended tail edge suppression zone shorter than the dead path or the distance run by the conveyor within a dead time set in menu C4, C6, or C8 ? is this intended zone shorter than 2/3 of the copy length ? no no invalid configuration ! yes yes set C10 or C11 Output pulse delay to value equal to the intended tail edge suppression
C14: Input values: Function: Comments: Short pulse suppression [ShrtP.Suppr.] short edges are not suppressed 0 = off 1 = on short pulses are suppressed 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. This parameter is accessible only if menu C2 False pulse suppression was previously activated (C2 = on).
Comments: C18: Input values: Function: Comments: Threshold [Threshold] 20 to 799 in steps of 1 to define the value which marks the beginning of an edge when the ratio v/r drops below this value. This parameter is accessible only if menu C16 customized sensitivity mode was previously activated (C15 = 1). Hysteresis [Sens. Hyster.] 1 to 499 in steps of 1 to define how much the ratio v/r must rise above threshold in order to initiate the end of an edge.
