Installation procedure (overview)
Reading pulses via switching input "Sensor 1" (default setting)
1. Check the delivery to make sure that none of the components is missing.
2. Mount the CLX at the reading station and align it with the object carrying the bar code.
3. Mount the AMV/S 60 Connection Module.
4. Connect the CLX to the AMV/S 60 Connection Module using the two cables no. 2 020 302. Alternatively, connect the device to the AMV/S 60 via the external parameter memory no. 2 020 307.
5. Connect the reading pulse sensor to the "Sensor" switching input in the AMV/S 60.
6. Connect the host to the host interface in the AMV/S 60. Adapt the AMV/S 60 to the host interface type of the CLX.
7. Switch on the power supply to the AMV/S 60. The "Device Ready" LED lights up after the CLX has started.
CLX with external parameter memory connected:
The "Device Ready" LED and the "Read Result" LEDs blink after the CLX has started. The CLX is

HTML browser on your PC.
10. Connect the PC to the terminal interface of the CLX. To do so, connect the RS 232 cable (e. g. no. 2 014 054) to the "Service plug" in the AMV/S 60.
11. Start the "CLV-Setup" program. CLV-Setup establishes communication with the CLX and uploads the parameter set. The parameters are then displayed on the tabs.
CLX with external parameter memory connected:
First download the CLX parameter set to the external memory. Disconnect the AMV/S 60 briefly from the power supply to restart the CLX.
12. Carry out a test read using test bar codes (clock the CLX accordingly). Display the reading result in the Terminal Emulator window of the "CLV-Setup" program.
13. Configure the CLX for the application using the settings on the tabs in CLV-Setup. Copy (download) the modified parameter set to the CLX temporarily.

Safety information
Internal protective circuits
The CLX is equipped with monitoring circuits that deactivate the laser diode in the event of a malfunction.
Activation and deactivation of the laser diode is controlled by the reading pulse trigger.
A timer (laser timeout) automatically deactivates the laser diode in Reading mode ("Sensor input" and "Serial interface" trigger mode) if the reading interval has not ended after 10 minutes (default setting). However, it does not end the reading interval. In this case, the CLX outputs the message
"Laser safety timeout"
on the terminal interface. The reading interval must be terminated by resetting the trigger signal. The laser diode is activated again by the next reading trigger.
The laser timeout can be set in the range of 1 min to 25 h or deactivated

3.2 Method of operation

The CLX first scans the bar code with a folded scan line (resulting in a cross) and then de­codes it. The data is forwarded via the main data interface (serial host interface) to a host/ PC for further processing. An overview of the CLX functions is provided in

The CLX is equipped with two decoders:
The SMART decoder (SICK Modular Advanced Recognition Technology) for decoding bar codes with small code height, bar codes that are dirty or damaged, as well as bar codes that are tilted excessively (azimuth angle)
The tried-and-tested standard decoder of the CLV series
The CLX derives useful diagnosis data from the reading process and can transfer it also to the host. It also records operating data that can be interrogated at any time. The quality of the read can be checked in percentage evaluation mode.
To start the reading process when an object is located in the reading field, the CLX requires a suitable trigger. This opens an internal time window ("reading interval") in the CLX. In the default configuration, this trigger is supplied by an external reading pulse sensor. Alternative trigger sources include free-running mode or a command via the host interface (for more complex applications: OTC trigger).
With small object distances (object distance < reading gate length) the bar code has to be allocated to the right object with the help of the internal tracking of the CLX.
The current operating status is indicated by four LEDs.
If the trigger is supplied externally, the "Sensor" switchi ng in put instructs the CLX to sta rt th e reading process. The five "IN 0 ... IN 4" switching inputs switch the focus position in response to certain events, as an alternative to the autofocus function. The "IN 4” input can also be assigned to special functions. The four "Result 1 ... Result 4" switching outputs can be assigned to different functions alternativly for displaying the result status and also control external devices, such as a PLC.
The CLX is operated and configured via the auxiliary interface (serial terminal interface) using the CLV-Setup software or via the host interface/terminal interface using command strings.
System, warning, and error messages help you configure the device and locate the source of errors during startup and reading mode.

3.2.1 Autofocus function

The autofocus function enables the CLX to detect the distance of an object during the read­ing process, without the need for external sensors, and then adjust the focus position auto­matically to the reading plane of the bar code. In order to do so, the CLX measures the object distance each time in its reading field in front of the reading window and internally cre­ates a distance profile. Following this, it positions the focus on the object.
3 operating modes are provided for various applications:
Minimum distance:
the CLX focuses on the minimum distance in the distance profile and ignores the background in the reading field. Application: with unobstructed view of the object without any surrounding objects protruding into the reading plane. One object with bar code(s) only is inside the reading field during one reading pulse.
Differential background:
the distance profile of the reading field background is pro­grammed (teach-in) in the CLX without any objects present. During the reading process, the CLX then focuses on the object which it recognizes by comparing it to the distance profile of the background. Application: with unobstructed view of the object restricted by other objects that protrude into the reading plane. One object with barcode(s) only is inside the reading field during one reading pulse.
Differential background and tracking:
if several objects with different distances are positioned in the reading field at the same time (distance conflict), the CLX focuses on the object that is nearest to but has not exceed its internal focus switchover point. Application: in OTS operation (applications with tracking by the OMNI Tracking Controller OTC 400), or stand alone in internal tracking mode.
The distance profile of the background can also be displayed in the "CLV-Setup" program. The reading field is defined by the autofocus range. The park setting of the focus position, from which the device focuses for each read, can be specified in addition to a time and/or position-related delay (timeout or hysteresis). If necessary, an offset can be defined for the focus position to be set by the measurement. The depth of field, which radiates in the direc­tion of the scan line and is caused by the V-principle of the beam deflection, is optimized as a result (
Fig. 3-3
).

3.2.2 Event-controlled dynamic focus control

As an alternative to the autofocus function, the CLX can switch its focus position in response to certain events and thus dynamically cover a large reading range. A maximum of eight reading ranges can be defined as distance configurations for this purpose and approached consecutively in reading mode (see
Fig. 3-4
).

The switch over takes place in response to changes in the object distance (with reads from above: object height detection). The trigger source for the switchover is a signal combination at the "IN 0 ... IN 4" switching inputs, a command on the host interface/terminal interface or the integrated timer (e. g. for search mode). The distance configurations are assigned to the swichover sequence by means of a programmable assignment table. The distance mea­surement of the autofocus function can additionally be used to define the distance configu­rations.

3.2.3 Additional components

Heater
The CLX can be permanently equipped with a heater for applications involving temperatures up to max. –30 °C (e. g. in a freezer).
The design, technical data, and power-up behavior of the CLX are described in
Optional heating, Page 10-12
External parameter memory
The external parameter memory is located in a connector cover which, when mounted, covers the two electrical terminals on the CLX (IP 65). The parameter memory saves you time when a CLX is replaced locally by providing a copy of the current parameter set. In other words, you do not have to configure the new device.

4.2.5 Selecting the mounting location

When you select the mounting location, the distance between the CLX and the host and between the CLX and the bar code are extremely important.
Distance between the CLX and the host
The CLX can be mounted at a maximum distance of 1 200 m from the host without a connection to the SICK network or a bus. In practice, however, the distance depends on the physical configuration of the host interface and the data transfer rate (see
Table 5-7,
Page 5-8).
Distance between the CLX and the AMV/S 60 Connection Module
The AMV/S 60 Connection Module should not be located further than 10 m from the CLX, since the "CLV-Setup" program on the PC accesses the terminal interface (RS 232) of the CLX via this module.
