Parameterization
Windows® software SI-LCC-Scope V1.0:
The LCC-80 laser copy counter can be easily parameterised with the Windows® user interface.
For this purpose the LCC-80 system is connected to the PC with the serial interface cable cab-las5/PC.
When parameterisation is finished, the PC can be disconnected again.
Windows® user interface
PMOD:
In this function field the operating mode of automatic power correction at the transmitter unit (laser) can be
set.
FIX:
In this operating mode the POWER function field is enabled for setting purposes. The laser
transmission power is kept constant at the value set in the POWER function field.
DYN: In this operating mode the POWER function field is disabled for setting purposes. The laser
transmission power is automatically and dynamically controlled in accordance with the
amount of radiation that is diffusely reflected from the object. By using the intensities measured at
the receiver, the automatic control circuit attempts to adjust the transmission power in such a way
that the dynamic range is not exceeded.
POWER[%]:
In this function field the intensity of the laser diode can be set
(0% = Laser OFF, 100% = full laser diode intensity).
HOLD:
In this function field the pulse lengthening time [ms] (after detecting an edge) for OUT0 can be set.
PARA:
This changeover switch determines whether the parameters BACKLIM, REGCNT, AVERAGE, DEAD TIME MODE, and
DEAD TIME are displayed or hidden.
1 = Hide parameters
0 = Display parameters

Parametrisierung
Parameterization
THRESHOLD:
Input field for the lower threshold. The sensor sensitivity increases with a higher THRESHOLD value.
HYSTERESIS:
Input field for the desired hysteresis. For detecting an edge, the NORM VALUE of the two RAW
SIGNALS must drop below a certain THRESHOLD during measurement to initiate a counting event.
When the sensor detects an edge (NORM
VALUE drops below THRESHOLD), a
search for the minimum NORM VALUE is
performed until the end of the DEAD
TIME (TRIGGER=CONT) or the ACTIVE
TIME (TRIGGER=EXT) and during
HOLD. This minimum value is stored in a
16-value JUMP-BUFFER that can be read
out with the GETBUFF software button.
NORM
HYSTERESIS
After the value has dropped below a
THRESHOLD, the NORM VALUE must
again lie above the value set under
HYSTERESIS, to allow renewed edge
detection. This is an additional safety
feature to suppress multiple counting
around the THRESHOLD.

Parameterization
TRIGGER = CONT:
Measurement is performed continuously.
TRIGGER = EXT:
An ACTIVE WINDOW is set for the sensor by the two inputs IN0 and IN1. The window is opened with a positive signal edge at IN0, and is closed
again with a positive signal edge at IN1. The sensor measures during its ACTIVE TIME, and if it detects an edge, an output counting pulse is
provided immediately after the ACTIVE WINDOW is closed.
Only one edge can be detected during the ACTIVE TIME. Output OUT1 serves for monitoring the active time. For renewed edge detection, the two
inputs must detect a negative signal edge.
Application example:
Objects that are transported by means of mechanical or
other kinds of grippers. The trigger signals (+24V) can be
supplied to the sensor by means of inductive sensor or
light barriers, etc. The advantage of this method of
measuring is that the sensor is completely independent
of the speed.
TRIGGER = ADJ EXT:
For future measurements with an active window
(TRIGGER = EXT), this mode makes it easier for
the user to adjust the two initiators for the active
window; see picture below.
For operating the sensor with an active window,
two initiators must inform the sensor about the
active time. As described above, the active
window is opened with a positive signal edge at
input IN0 and is closed again with a positive signal
edge at input IN1.

The TRIGGER = ADJ EXT mode was introduced
to allow improved sensor adjustment. When this
mode is selected, the sensor records the time
from one positive signal edge at IN0 to the next
positive signal edge at IN0 and valuates this time
as 100%. This is shown in the graphic display,
when the GO button is pressed and SOURCE =
EXT is selected. When the GO button is pressed,
the data are automatically updated after one
second. The value of 100 on the x-axis
corresponds with 100% (time from IN0 to IN0).
The red graph visualised the length of the active
window in percent of the time between IN0 and
IN0.The blue graph visualises the appearance of
an edge in percent of the time between IN0 and
IN0.
It can be seen in the example shown here that the
active window is equal to 59% of the time from
IN0 to IN0, i.e. the sensor detected a positive
signal edge at IN1 after 59% of IN0 to IN0, which
closed the active window. The edge was detected
at 30% of IN0 to IN0. These two values are also
shown in the EDGE [%] and WIN [%] display
fields.
In practice, the active window should be open
approx. 60% of IN0 to IN0. The edge should lie in
the middle of the active window (30%).

Data Sheet
LCC-80
Parameterization
BACKLIM:
In this edit-box an intensity limit can be set. If the intensity that arrives at the receiver unit DAT0 (display
window in the user interface) drops below this limit, no evaluation will be performed.
REGCNT:
This edit-box serves for setting after how many loop runs dynamic laser diode correction should be
performed.
Example: SCAN frequency 15 kHz is equal to 66.6 μs
REGCNT = 75
Calculation:
66.6 μs * 75 = 5 ms
Result:
Dynamic correction is performed every 5ms
Explanation: Flatly rising magazines are detected, because dynamic correction is not performed with every
loop run, and the jump is automatically compensated, so to speak.
The EDIT-BOX REGCNT is enabled when PMOD = DYN.
When PMOD = FIX the EDIT-BOX REGCNT is disabled as no laser transmitting power correction is done.
AVERAGE:
This edit-box serves for setting averaging through NORM.
The minimum value for averaging is 1.
The maximum value for averaging is 128.
An average of 1 is sufficient for most applications.
Please note:
If AVERAGE = 1, the internal scan frequency = 15 kHz.
If AVERAGE = 2, the internal scan frequency = 7.5 kHz.
If AVERAGE = 4, the internal scan frequency = 3.75 kHz.
etc.
OUTMODE:
This edit-box determines how the output impulse should be output at OUT0:
Direct:
When a counting event occurs, output OUT0 changes from LOW (0V) to HIGH (+24V),
until HOLD is over.
Inverse:
When a counting event occurs, output OUT0 changes from HIGH (+24V) to LOW (0V),
until HOLD is over.
DEAD TIME MODE (DT MODE):
This function field shows the DEAD TIME MODE that is used.
DT MODE = FIX:
A fixed dead time is used. The dead time is set in milliseconds under DEAD TIME [ms].
DT MODE = DYN:
A dynamic dead time is used. The dead time is set in percent under DEAD TIME [%].
The time between two edges is valuated as 100%. The dead time is calculated in accordance with the
percent value that is set under DEAD TIME [%]. The dead time can be measured through monitor output
OUT1 (low-active).
If TRIGGER = EXT is selected, the sensor operates with an ACTIVE TIME. In this case the input fields
DEAD TIME MODE and DEAD TIME [...] are disabled. The active time can be measured through monitor
output OUT1 (low-active).

Data Sheet
LCC-80
Parameterization
TYPE:
The data that are to be displayed in the graphic window (RAW, NORM) can be selected in this function field.
RAW:
The raw data DAT0 and DAT1 are visualised in the graphic window. In addition these values are displayed in the
two numerical value output fields DAT0 and DAT1.
NORM:
The NORM calculated from DAT0 and DAT1 is displayed in the graphic window. In addition this value is displayed
in the numerical value output field NORM.
GETBUFF:
When the GETBUFF button is clicked, the last minimum values of the NORM SIGNAL after edge detection are
displayed. In addition, the THRESHOLD which the values of the NORM SIGNAL must remain under is visualized
in the graphical display window.
Upon detection of an edge the sensor starts to search the minimum value of the NORM SIGNAL during the DEAD
TIME and HOLD. This value is then stored in a 16-value ring buffer. Based on these VALUES, the optimum
THRESHOLD for the current product run can then be set.
This group of function keys serves for parameter exchange between the PC and the control unit through the serial
RS232 interface.
SEND:
When the SEND button is clicked, all the currently set parameters are transferred between the PC and the control
unit or to an output file. The target of the respective parameter transfer is determined by the selected button
(RAM, EE, or FILE).
GET:
The current setting values can be called up from the control unit by clicking on the GET button. The source of data
exchange is determined by the selected button (RAM, EE, or FILE).
RAM:
The current parameters are written to the RAM memory of the control unit, or they are read from the RAM, i.e.
these parameters are lost again when the voltage is switched off at the control unit.
EE:
The current parameters are written to the non-volatile memory of the EEPROM in the control unit, or they are read
from the EEPROM, i.e. the parameters in the internal EEPROM are stored when the voltage is switched off.
FILE:
A click on this selection button opens an info field with the file name of the current parameter file.

Application Example
Copy counting at compensating stackers
The LCC-80 or LCC-90 laser copy counter even detects
high-gloss copies of different thickness with highest
reliability. Because of the special evaluation method,
different conveying speeds have no influence on the
counting result.

The initiators are mounted in such a way that the position

taken to ensure that both sensor 1 and sensor 2 detect
every clamp.

IN0 (next clamp)
Furthermore, the distance of the two sensors with respect
to each other must be chosen in such a way that, with
respect to time, the output signal of the laser sensor lies
approximately in the middle of trigger signals IN0 and IN1.
The ADJEXT mode that con be activated in the SI-LCC V1.0
Windows® software, serves as a setting aid for this;
the chart indicates the positions of IN0, OUT0, and IN1
(initiator 1, laser copy counter, initiator 2). Based on the
assumption that IN0 to IN0 = 100%, IN0 to IN1 should
be approx. 60%, whereas IN0 to OUT0 should lie at
approx. 30%.
