LCC Series
Laser Copy Counters
LCC Series laser copy counters primarily are
designed for detecting and counting magazines
or single sheets in imbricated arrangement.
In the optimal operating range they detect sheet
edges of a thickness of typ. 50 ěm.
The
sensors of LCC Series are characterised by
their reliable function, their ease of operation,
and their sturdy mechanical construction.
Further characterising features of this
sensor series
are their high scanning frequency and their ability to
adjust themselves to differently bright and dark,
or slow and fast moving parts.
Characteristics
Parameterisation under Windows® with software
SI-LCC V1.0 respectively SI-LCC-MA V1.0
The
sensors can easily be set with the help of a Windows® user interface
in which the
sensor signals are displayed in numerical and graphical form;
the user interface also provides various software algorithms and setting
parameters.
With software version SI-LCC-MA V1.0, some parameters can also be set
with DIP and HEX switches.
Parameters such as e.g.
- Threshold (sensitivity)
- Hysteresis
- Laser power mode (static or dynamic)
- Output pulse lengthening
- Dead time (static or dynamic)
can be set with the software, or with types LCC-...-MA by means of
HEX and DIP switches.
Functional principle of the
sensor
The LCC-... laser copy counter comprises a laser transmitter (laser
diode, l=670 nm) and two receivers. The laser beam is focussed at
an angle onto the magazine or sheet opposite to the direction of feed.
When an edge arrives, it blocks the beam path to receiver 2, whereas
the signal at receiver 1 slightly increases due to the more favourable
angle of impingement! The standardised (NORM) value of SIGNALS
A and B is used as the starting signal for all the further algorithms of
the laser copy counter!
