Object trigger control
In order to initiate a reading process, the ICR890 System requires an appropriate signal
(trigger). The start signal is emitted via an external reading pulse sensor (
photoelectric
reflex switch
) as standard. As soon as an object has passed the reading pulse sensor, an
“internal reading gate“ opens for the reading process.
Alternatively, a command activates the reading process via a data interface or the CAN-
SENSOR network.
The trigger source can be configured using the SOPAS-ET Configuration Software:

Focus control
For dynamic focus control, the ICD890 Camera requires continuous information on the
distance to the object surface. This data is provided by a lateral
MLG Light Grid
for readings
from above. The object dimensions are taken from the
VMS4xx/5xx Volume Measurement
System
and processed via the MSC800 for readings from the side.
The SOPAS-ET Configuration Software can, among other things, be used to configure
features, such as the default position and the source of the distance measurement:

Illumination control
The area which is to be read must be illuminated with a high-performance LED illumination
when recording with the camera. The
ICI890 Illumination
produces a thin red illuminated
area (wavelength
λ
= 620 nm).
During reading from above, the light is deflected onto the conveyor system using the
deflection mirror
.
