cording to valid engineering standards.
2.3.3 LEDradiation
LED radiation!
The illumination of the ICR845-2 op erates with LEDs of LED class 1.
Under normal and sensible conditions, the accessible radiation of the LEDs is not hazard-
ous. Blinding, impairment of ability to see color, or other irritations, however cannot be ex-
cluded.
The entire area of the reading window ( Fig. 2-1 ) acts as a LED outlet aperture.
Caution – use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
Never look directly into the illumination.
Do not open the housing.
(Opening the housing does not deactivate the LEDs by the reading pulse.)
Always observe the latest valid version of laser protection regulations.
Radiation power

The product is classified in LED class 1 in accordance with EN 60825-1 and IEC 60825-1
(for publication date, see the warning sign on the device).
Important
Maintenance is not required to ensure compliance with LED class 1.
Warning labels
At the ICR845-2, the warning label ( Fig. 2-2 ) in three languages and the warning symbol are
located on the wide side of the housing.
If the ICR845-2 is installed in a machine/panel with the result that the warning labels are
no longer visible, additional warnings (not included in the scope of delivery) must be pro-
vided on the machine beside the emergence aperture of the LED radiation.
Controlling the illumination LEDs
Activation and deactivation of the LEDs when reading is controlled by the reading pulse
(trigger source).
A timer (illumination timeout) automatically deactivates the LEDs 10 minutes (default
setting) after a continuous reading pulse is initiated in Reading mode with switching in-
put pulse modes "Sensor Input" and "Serial Interface". However, it does not end the

iary interface:
"Illumination safety timeout"
The reading interval must be terminated by resetting the trigger signal. The LEDs are
activated again by the next reading pulse.
Theillumination timeout can beset in therangeof 1 min to 25 h or deactivated.
The illumination LEDs are periodically activated in the operating mode "Percentage
Evaluation" and are always activated in the pulse mode "Free Running" in Reading
mode.
2.4 Quick stop and quick restart
2.4.1 Switching the ICR845-2 off
Switch off the power supply or remove the ICR845-2 cable plug from the connection

(operating hours counter, reading interval co unt, good read count, no read count, max-
imum duration reading interval, minimum duration reading interval, number of match-
es with match code 1, number of matches with match code 2, number of No Matches.)
2.4.2 Switching the ICR845-2 on again
Switch on the supply voltage or reattach the ICR845-2 cable plug to the connection
module.
The ICR845-2 resumes operation with the last permanently stored parameter set and

Product description
This chapter describes the design, the fe
atures and the functions of the ICR845-2.
For installation, electrical installation and startup assistance as well as for the applica-
tion-specific configuration of the ICR845-2 using the CLV-Setup configuration software,
please read this chapter prior to carrying out any of the tasks.
3.1 Design of device
The ICR845-2 consists of a image recording system (lense and CMOS matrix sensor with
global shutter) and an electronic unit (image processing system with integrated decoder).
The image recording system and the electronic unit are located in an industry-compatible
housing. The light exits and enters via a reading window in the housing, which also contains
an arrangement of LEDs for illuminating the reading area.
For an adaptation to on-site space conditions two housings are available: a housing with
front reading window and a housing with side reading window. Via the integrated angle at-
tachment, the reflected light enters through the side reading window at an angle of 90 re-
ferred to the centre-line of the housing.
Depending on the type, various lenses enable different resolutions and reading ranges.
The ICR845-2 is electrically connected by a shielded cable with a D-Sub HD plug and by an
RJ45 socket on the housing. The ICR845-2 meets the enclosure rating IP 65 using an optio-
nal adapter frame with the corresponding Ethernet cable or a corresponding cover.

Product description
3.4 Method of operation
The ICR845-2 consists of a image recording system (lense and CMOS matrix sensor with
global shutter) and an electronic unit (image processing system with integrated decoder). It
reads and decodes 1D codes (bar codes) and 2D codes.
3.4.1 Image recording
For image recording the ICR845-2 takes a rectangular image of the area to be read. To do
so, an illumination lights the area to be read . The LEDs of the illumination generate a red
illumination field (pulsed) with a flash freque ncy and duration calculated by the ICR845-2.
When starting a reading cycle, the ICR845-2 sw itches on the illumination. With the matrix
sensor the ICR845-2 absorbs repeatedly the light reflected from the field of view (
Fig. 3-4
)
through the lens as gray values. The recorded images are stored in an electronic image buff-
er memory. To prevent distorted images while the image are being recorded, the shutter
speed must be adapted to the velocity of the objects carrying the codes. The velocity per-
mitted depends on the cell size, the contrast of the code layout and the flash duration.
The field of view, which is mapped in sharp focus by the ICR845-2 on its matrix sensor, de-
pends on the reading distance and, depending on the resolution, must be within the reading
range (DOF). Chapter 9.3 Specification diagram, Page 124 shows the available field of
view. The image recording rate is 60 Hz at full matrix sensor ulitisation. If the appropriate
configuration settings are made to reduce the matrix sensor area (image geometry) used
for the evaluation, this increases the potential image recording rate. The ICR845-2 automat-

ically adjusts the flash frequency and duration. With a maximum of two working areas, a
maximum of just two separate strips in the im age field can be evaluated. To read the codes
successfully when the active field of view is reduced, the objects must be routed exactly and
the codes must be fixed in the same location.
On request, the ICR845-2 outputs the image bu ffer memory content as binary or grey scale
bitmap via the Ethernet interface. The images can be displayed by the Image FTP program.
3.4.2 Decoding
As codes are detected in the image data, th e ICR845-2’s decodingalgorithms determine
the code(s) contents. At the end of the read ing cycle the ICR845-2 outputs the code data
information via its host interface to a host/PC for further processing.
The ICR845-2 is equipped with four decoders:
The decoder for omni-directional reading of 2D codes
The tried-and-tested standard decoder of the CLV series for 1D codes (bar codes)
The SMART decoder ( S ICK M odular A dvanced R ecognition T echnology) for decoding
1D codes on following conditions:
– small aspect ratio (ratio of the code height to the code length)
– dirtyor damaged printed code
– bar codes that are tilted excessively(azimuth angle)
The 360°-decoder for omni-directional reading of 1D codes
The ICR845-2 derives useful diagnosis data from the reading process and transfers it to the
host. It also records operating data that can be requested at any time. The reading quality
of 2D codes can be checked in the "Percentage Evaluation" operating mode.
3.4.3 Reading triggering and indicating of result status
To start the reading process when an object is located in the field of view, the ICR845-2 re-
quires a suitable trigger. This opens a time window ("reading interval") in the ICR845-2 for
the reading procedure. In the default setting, th is trigger is supplied by an external reading
pulse sensor. Alternative trigger sources include Free Running mode or a command sent via
the host interface.
The current operating status is indicated by four LEDs. A beeper indicates the status of the
reading result. In the default setting, the "Good Read" function is selected for this.
If the trigger is supplied externally by a sensor, the "Sensor 1" switching input signals the
start of the readingprocedure to the ICR845-2. The "Sensor 2" switchinginput is used to
signal alternatively the end of reading procedure or to enter a path increment. It can also be
used e.g. to teach in a match code.
The"Result 1" and"Result 2" switchingoutputs can be assigned variousfunctions and trig-
ger external devices, such as a PLC. Using the "Result 1" output, an external illumination can
additionally be triggered or directly powered (max. 100 mA) by the ICR845-2.
The ICR845-2 is configured via the serial auxili ary interface/host interface with the CLV-Set-
up configuration software or with command strings. Alternatively, the Ethernet interface is
available for both types of operation.
The ICR845-2 outputs system and error messages as error codes, which can be requested
from the error memory using command strings.

3.5 Indicatorsand control elements
3.5.1 Control elements
The ICR845-2 is configured application-specific
ally using the CLV-Setup configuration soft-
ware. The software runs on a PC which must be connected to one of the two data interfaces
(auxiliary interface: serial RS 232 or Ethernet, host interface: serial RS 232/RS 422/485 or
Ethernet) of the ICR845-2.
Chapter 10.4 Installation and operating instructions for the CLV-Setup configuration soft-
ware,Page 136 describes the procedure for installing the PC software "CLV-Setup" and ex-
plains how to use it. Configuration is explained in Chapter 6 Startup and configuration,
Page 47.
As an alternative to the CLV-Setup configur ation software, command strings are available
upon which the user interface of the CLV-Setup configuration software is based (see also
Chapter 10.5 Configuringthe ICR845-2 with command strings, Page 146.
Start-up as well as diagnosis in case of an error can be carried out via the CLV-Setup con-
figuration software. Some function can also be started using the function key. The ICR845-
2 operates fully automated in normal operation.
3.5.2 Function keyon the housing of ICR845-2
With the function key you can start a pre-configurated function without using the CLV-Setup
configuration software. At the moment, only the reading interval can be started. On the de-
vice, the foil key is located nearby the LEDs ( Fig. 3-1, Page 14 ).
In the default setting the function key is active. The key can be deactivated with the CLV-
Setup configuration software.
Chapter 6.5 Usingthe function key, Page 68 describes how to use the key.
3.5.3 Function of the LEDs
General LEDs
Four LEDs indicate the operating status, activity of the illumination LEDs, the reading result
status and data transfer on the serial host interface.
The LEDs are located on the rear of the device toward the bottom ( Fig. 3-1, Page 14 ).
Table 3-4 shows the meaning of the LEDs in the different operating modes/functions.
