2.2 Intended use
The ICR845-2 is an intelligent sensor for the automatic reading and decoding of 1D codes (bar codes) and 2D codes on objects in a read cations in which the codes are read either on objects transported with high velocity or on not moved objects.
The ICR845-2 transfers the reading data via its host interface (serial RS 232/422/485 or Ethernet) to a host computer for further processing.
The ICR845-2 is configured/operated using the CLV-Setup configuration software that runs on a standard client PC (WindowsTM) provided by the customer.
Any warranty claims against SICK AG shall be device, such as opening the housing, this in electrical installation or changes to the SICK software.

2.3 General safety precautions and protection measures
Read the general safety precautions carefully and observe them at all times. This also applies to the warnings and operating instructions in the individual chapters of this doc­ument.
2.3.1 RF interferences
RF interferences in case of use in residential areas!
The ICR845-2 Image Code Reader is exclusively intended for use in industrial areas.
2.3.2 Electrical installation
Risk of injury by electrical current! In the CDM420 Connection Module, the CMP400 Power Supply Module is connected to a
mains voltage of 100 to 250 V AC/50 to 60 Hz.
When working with electrical equipment, always follow the relevant safety regulations.
Important
Electrical installation should only be carried out by qualified staff. Connect or disconnect current linkages only under de-energised conditions. Wire cross sections and their correct protection have to be selected and implemented ac-
cording to valid engineering standards.
2.3.3 LED radiation
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 hazard­ous. Blinding, impairment of ability to see color, or other irritations, however cannot be ex­cluded.
The entire area of the reading window (
Fig.2-1
) acts as a LED outlet aperture.
Caution – use of controlsoradjustments or performanceof proceduresother 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.
10
Radiation power The illumination LEDs operate at a wavelength of
= 617 nm
15 nm (visible red light)
with a pulse duration of max. 5 ms. The energy in the human eye is < 2.1 J/m2.

Important
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). Maintenance is not required to ensure compliance with LED class 1.

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 pro­vided 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

The ICR845-2 consists of a image recording system (lense and CMOS matrix sensor with global shutter) and an electronic unit (image 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.

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

ing cycle the ICR845-2 outputs the code data
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 (SICK Modular Advanced Recognition Technology) for decoding
1D codes on following conditions: – smallaspect ratio (ratio of the codeheight to thecodelength) – dirtyordamaged printed code – bar codes that aretilted 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.
8012377/0000/2008-01-30
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 reading procedure to the ICR845-2. The "Sensor 2" switching input 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" switching outputs can be assigned various functions and trig­ger external devices, such as a PLC. Using the "Result 1" output, an external illumination can additionally be triggered

3.5.2 Function key on 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 de­vice, the foil key is located nearby the LEDs (
