Laser Warning Labels

APPLICABLE WARNINGS and LABELS

FCC Compliance

The CLV has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his own expense.

Personnel Safety Warning

The CLV emits a red light beam from a Class II laser diode. The beam is extremely bright and, like any bright light, may cause eye damage unless you exercise caution. Please note the following warning.

WARNING: LASER LIGHT. Do not look directly at the light source. Laser light can cause eye injury after prolonged exposure.

The CLV meets all safety requirements for Class II laser products. This includes standards of the United States Department of Health and Human Services Center for Devices and Radiological Health; IEC 825, VDE 0837. The CLV laser warning labels are shown in the following figures.

Bar Code Scanners

Introduction

SECTION 1-INTRODUCTION

THEORY OF OPERATION

The CLV uses a scanning laser beam to detect the contrast between the light and dark portions (bars and spaces) of a bar code. Figure 1-1 shows the system in simplified form. In operation, light from the laser diode (1) is directed by the corner mirror (3) onto one facet of the mirror wheel (2). Rotation of the mirror wheel in the direction of the arrow causes the beam exiting through the window to scan at a 60° degree total angle (4). When the scanning beam strikes a bar code in the reading plane (6), a portion of the incident light is reflected back through the window onto the mirror wheel then onto the corner mirror. From the corner mirror, the reflected beam passes through the filter (10), is converted to an electrical signal by the photoreceiver (11), amplified (12), and then digitized in the binary conversion stage (13). This digitized signal (8) which now matches the bar code symbology (7) is routed to the integrated decoder where it is decoded to reconstruct the information contained in it. System output is transmitted to a terminal, a printer, or a host device.

LIGHT SOURCE

The standard CLV uses a visible red light (670 nm) laser diode for the scanning operation. An alternative infrared invisible laser source is available where needed for optimum contrast. Maximum average power at the reading window is limited to 1.0 mW, giving a CDRH classification of safety class II for both red light and infrared versions. The user is cautioned not to look into the laser beam or at direct reflections of the beam.

This Installation and Operation Manual should provide you with the basic information you need to install and start operation of your CLV 410/412 Bar Code Scanner. For information on using the CLV Utility Software, see SICK Optic-Electronic’s publication “CLV Utility Software Guide ” part number 7 020 809. This extensive manual contains information applicable to many of the CLV Bar Code Scanners.

Figure 1-2 Bar Code Label Orientation

SCANNER SELECTION

The CLV 410/412 scanners are available in a line or raster version. The CLV 410 has a reading range of 2 in to16 in, depending on the x-dimension of the bar code label. The scanner is designed to read medium to low resolution bar codes from .2 mm (.008 in) to 1.0 mm (.040 in). The CLV 412 has a reading range of 35 mm (1.38 in) to 95 mm (3.74 in), depending on the x-dimension. The CLV 412 is designed to read high density bar codes from 0.1 mm (.04 in) to .20 mm (.008 in). The scan rate for both scanners is adjustable from 200 Hz to 800 Hz.

The following factors determine scanner selection:

• Bar code label orientation with respect to direction of transport (see below)

• Physical location of bar code and its alignment on the conveyed product

• Size of the scanning field required

• Space available for installation of bar code scanner

• Speed of conveyor line

LABEL ORIENTATION

The bar code will be presented to the bar code scanner in one of two ways: in the “ladder” orientation or in the “picket fence” orientation.

In “ladder” orientation applications, the bar elements of the bar code are parallel to the direction of transport (Figure 1-2 A). In “picket fence” orientation applications, the bar elements of the bar code are perpendicular to the direction of transport

(Figure 1-2 B).

A: Ladder Orientation B: Picket Fence Orientation

LINE SCANNER

A single beam line scanner is used when the bar codes are being presented to the scanner in the “ladder” orientation (shown in Figure 1-2 A). The scanning direction is perpendicular to the conveyed direction and the entire bar code is presented to the scanner. The usable length of the scan line, or “scan width,” is dependent on the scanning distance.

RASTER SCANNER

If the bar codes pass the scanner in a “picket fence” orientation, a raster scanner is recommended to ensure complete scanning coverage of the bar code. See Figure 1-2 B. Refer to adjacent table to determine raster pattern height according to reading distance.

PROGRAMMING

The CLV is programmed at the factory with default settings for each parameter. The default settings are considered temporary, for use at start-up or for testing the system. In order to achieve optimal operation, the user can directly modify default parameters for the intended application. Programming, or parameterization, can be performed by using one of the following:

• Windows-based CLV Utility Software (included) via host port

• Host Command Language Strings via host port The CLV 410/412 have a single interface port called the host interface. The table below shows the default parameters of the host

interface:

Parameters Setting Type RS 232 Data transmission rate 9600 Baud Parity; data bits None; 8 data bits Stop bit 1 Protocol None

These communication default parameters are set temporarily for 5 seconds after power up to allow a user to program the CLV if permanent settings are forgotten.

STORAGE OF PARAMETERS

The CLV stores all parameter values either temporarily in the working memory (RAM), where it remains until the system is turned off, or permanently (non-volatile memory) in the EEPROM. The CLV Utility Software also stores the parameter values in a file that can be saved on a disk.

RECEIVING / UNPACKING

The CLV was completely tested under normal operating conditions and thoroughly inspected before shipment. Unpack the CLV as follows:

1. Carefully remove and inspect all parts in the shipment for evidence of damage.

2. Check contents of shipment against the packing list.

LASER PROTECTION

All models of the CLV 410/412 line offer adequate safety to personnel by limiting the average emission power to 1.0 mW. If generation irregularities occur, internal protective circuits turn the laser off.

Laser warning labels on the CLV are reproduced on page 1 under “Applicable Warnings and Labels.”

LED FUNCTIONALITY

There are four indicator LEDs on the CLV:

END OR SIDE SCANNING

Installation

MOUNTING AND ALIGNMENT

The CLV should be mounted to permit alignment in three planes, with consideration for the bar code orientation on the conveyed product. The CLV has two 5 mm (0.197 in) deep M4 tapped mounting holes located adjacent to the connectors.

Side Scanning

The illustration to the right shows the scanner in the side scanning configuration. Simply mount the scanner with the scanner body parallel to the surface to be read. The position of the exit window provides the recommended 15 degree reading angle (skew angle) which reduces surface reflection.

End Scanning

The illustration shows the scanner in the end scanning configuration. In order to reduce surface reflection, mount the unit so that the body of the scanner is approximately 15 degrees from being perpendicular to the surface for reading

Figure 2-6 Daisy Chain Configuration via CLV Host Port

DAISY CHAIN CONFIGURATION

This configuration allows connection of several scanners to one interface port of the host device. There are two modes of operation in this configuration: master/slave or pass-through. There should be no more than 8 scanners used in these modes. Refer to Figure 2-6 for an illustration of a daisy chain configuration.

Master/Slave Mode

For guidance in operating the scanners in the master/slave mode, refer to page 39.

Pass-Through Mode

In this mode of operation, the data from one scanner is passed to the next scanner in line and this is passed on again, etc. The last scanner in line then transmits the data to the host device.

There is no time delay in this mode of operation, since each scanner provides a virtual connection. The procedure required to activate this mode includes conditioning the output of each scanner to contain <STX>/“Data” <ETX>.

The “/” (forward slash) character is entered into the first position of the “Header” section. The CLV uses the variable protocol framing <STX> and <ETX> characters which are selected in the Host Interface: Protocol sec-

tion. The forward slash is a special character to indicate the pass-through mode. Thus, the CLV receives the information and immediately transmits the data to the host or to the next scanner in line.

To program the CLV scanner, activate the CLV Utility Software and use the “Upload” icon to upload the contents of the CLVscanner. Refer to figure 3-2. This procedure displays the current settings of the CLVscanner and creates a working parameter file. Other options to create a working file are to select “New” or “Open” on an existing file saved to the disk. Once a working file has been created you can make the necessary changes. After changes are completed, use the “Download” icon to download the new changes to the CLV scanner.

If you want the CLV scanner to retain the new changes permanently in the EE prom, select “Permanent” when the “Choose Download Options” box is displayed. Refer to Figure 3-2. If you select “Temporary” the new changes will be held in the CLV scanner’s RAM memeory.

Note: Since the CLV only has a single communications interface there are certain parameters (baud rate, protocol framing characters, network mode) which will prevent the CLV from communicating with the CLV utility software. The software will automatically determine baud rate and protocol framing characters. Use the icons shown to the right or the “default” bar code to establish communication. The Configuration Profile default parameter bar code is included. Simply scan it to set communication defaults or program the CLV within 5 seconds after power up as the communication default are set temporarily.

UPLOADING AND DOWNLOADING

This section describes the modes of CLV operation and includes an extensive discussion of parameterization, the process used to configure the CLV to best accommodate your particular application.

The CLV can be programmed using the Windows-based CLV Utility Software (included) or a host device using the CLV Host Command Language strings. This manual uses the CLV Utility Software as its basis.

MODES OF OPERATION

The CLV has two major modes of operation: the Reading Mode (entered automatically after power-up) and programming configuration mode. The programming/configuration options (Parameterization, Percent Evaluation, and Operating Data) are explained in detail below.

Parameterization: Used to program the CLV scanner to best meet the demands of the desired application. Percent evaluation: Continuous scanning mode that generates statistical information used mainly for alignment and adjustment

(optimal beam position) when installing the CLV. Operating data: Used for polling and resetting internal operating data of the CLV. The submenu of this operating mode is

•EAN 128 Each type of bar code is introduced below with

a brief explanation of the composition of the code. In one reading gate, up to ten bar code labels (up to ten different symbologies) can be decoded. The bar codes may appear simultaneously in a single scan or consecutively during the reading gate.

The CLV is capable of reading and evaluating the following bar code symbologies:

Number of Codes Minimum (1-10) (Minimum Number of Codes)

If more than one code is to be read in a reading gate, the minimum number of codes (1-10) that will be presented to the scanner during the reading gate must be entered. If, at the end of the reading gate, the minimum number of bar codes were not decoded and if the error status valve is activated, the CLV sends the data and an error status code (ST=2).

Maximum (1-10) (Maximum Number of Codes) The maximum number of codes (1-10) that will be presented to the scanner during the reading gate must be entered. The CLV will transmit only the number of bar codes specified here, even if the actual number of codes presented to it exceed this value. At the very least, maximum = minimum number of codes.

Code Position (Compare/Minimum Distance of Labels) The CLV performs code position comparison, i.e. the scanner recognizes the position of bar codes in order to identify whether identical readings are a result of the same or different bar code labels. The CLV scanner breaks the scan line into 100 units referred to as “code positions” (Figure 3-3). If CP-Comp. Multir. is activated, the CLV will determine the bar code position for each read. If the bar code positions differ more than the “minimum distance between labels” setting, the scanner will acknowledge multiple labels. Valid range for the “minimum distance between labels” parameter is 0.4 in to 39 in (10 mm to 999 mm).

SICK Optic-Electronic Bar Code Scanners

Software Configurations

Code Length (free/interval/fixed) The scanner can be programmed to read bar codes of any length or only those of a particular length (entered by the user):

“free” - Bar codes of any length between 1 and 49 characters will be read. “interval” - User may enter a range of lengths within which the scanner will read the codes. Valid entries are from 1 to 49. “fixed” - User may program up to five different fixed lengths to be read by the scanner. Valid entries are from 1 to 49.

Code length for Code 39 is calculated as follows:

number of bars – 10

Code Length = –––––––––––––––––––––

Multiple Reads (1-99) Enter the number of identical reads the scanner must decode (in one reading gate) before transmitting the result to the host device. This process increases output reliability. The selected scanning frequency and the speed at which the bar code is moving past the CLV should be considered when making this selection. If the number of multiple reads specified by the user is not fulfilled, the CLV will send the bar code string or error string (software selectable) to the host along with the error status ST=5, if the ST value has been placed in the separator.

Check Digit Test

For printed bar codes with an integrated check digit in the useful characters (last position before stop character), the check digit increases error detection and therefore reading reliability. With a “yes” response, the decoder activates a routine to compare the printed check digit with the check digit being calculated. The decoder then outputs the bar code data with the error status as follows: If the check digit test is successful, ST=0 (good read); if the check digit test is not successful, ST=1 (wrong check digit). The error status is output only if the error status value is activated as part of the data string. If the user responds here with a “no,” no check digit test will be carried out.

Transmit Check Digit

A “yes” allows the check digit to be transmitted to the host device. With a “no” response, the check digit is not transmitted. Note: The CLV automatically truncates the last digit of the data if “no” to transmit check digit is selected.

Module Width (auto/.50 mm/.33 mm) The module width refers to the width of the bar elements of the code. “Auto” is selected for a pharmacode label that has a combination of wide and narrow bar elements (1’s & 0’s). “.50” or “.33” are selected when the bar elements of the pharmacode label are all the same (all 1’s or 0’s). In the later case, the use is required to select the one that best represents the bar element width of the pharmacode label..

Direction (forward/reverse) Since pharmacode does not have start and stop characters, the scanning direction will affect the data set order. If “forward” is selected, the scanner will transmit the data set according to the scan direction. If “reverse” is selected, the scanner will transmit the data set in reverse order of the scanning direction. This feature is very useful when the orientation of the label changes and the scanner can accommodate this change without physically rotating the scanner.

Interpret FC1 (FC1 First Char ...... 3 values/FC1 in Code String ...... 3 values)

FC1 (Function Character 1) is a special character in the bar code label which carries out a certain function. In place of this FC1 value, the decoder inserts a sequence of up to 3 user-definable characters in the output string (exceptions are 06 hex, 11 hex, 13 hex, 15 hex, in addition to stop and start characters). The FC1 can be placed at the beginning of the data string or somewhere within the data string.

PHARMACODE

Pharmacode is one of the oldest bar codes. It is used primarily in the pharmaceutical packaging industry. Pharmacode is a numeric code which consists of two element sizes - wide or narrow. The wide bar represent a “1”, and the narrow bar indicates a “0”. There are no start and stop characters associated with the pharmacode. Thus, depending on the scan direction, different data sets may occur. Also, since there are no start and stop characters, adequate quiet zone is required.

READING CONFIGURATION

This function allows the user to program the CLV to read at selectable frequencies and select the appropriate minimum bar width of the bar code to be read.

Fig. 3-14 Reading Configuration

Custom Settings (Minimum Bar Width/Minimum Distance/Scanning Frequency)

Minimum Bar Width ...... mm (millimeters)

Minimum bar width is adjustable in steps of 0.004 in (0.01 mm). This refers to the X-dimension (narrowest bar element width), of the bar code. Set the scanner accordingly. The valid range is listed below..

default CLV 410 .008 in to .040 in (.2 mm to 1.0 mm) .008 in (.20 mm) CLV 412 .004 in to .008 in (.1 m to .2 m) .008 in (.20 mm)

Minimum Distance

This represents the closest distance from the scanner that the object will need to be scanned. Valid range listed below in 1 mm (.04") increments:

default CLV 410/412 .80 in to 16 in (20 mm to 400 mm) 1.0 in (25 mm)

“Picket Fence” Orientation Equation Scan Frequency = (V x N) Number of Scans = (W - L) x SF

––––––– ––––––––––––

W-L V

Following is an example for calculating scan frequency for a bar code in “ladder” orientation:

- Conveyor speed (V) = 100 ft/min = 20 in/sec

- Bar height (H) = .5 in

- Printed bar code 100% readable (material, printing, surface)

- Optimal adjustment of CLV (reading distance, angle, resolution)

- Required scans per code (N) = 10 20 x 10

SF= ——–——-

0.5

SF= 400 Hz

10 to 15 scans per code is usually sufficient. Any further increase does not produce better reading results. However, slower scan rates can help the scanner read codes that are harder to read. Some causes for this reduction are: a dusty lens on the CLV, small minimum width of the bar code, or bar code quality (i.e. poor print contrast).

Code Position Read Zone

This function allows the user to create an electronic mask. The scan line of the scanner is divided into 100 positions called Code Position (CP) values. By entering minimum and maximum CP values, you effectively create a reading zone within the scan line. This is very useful when the spacing of the objects to be scanned is small. The valid choices are 0 to 100 in 1 value increments:

Minimum CP ...... 0 to 100 default 0

Maximum CP ...... 0 to 100 default 100

The following variables and equations are valid:

Scan Frequency

Sets the scan rate of the scanner, from 200 to 800 Hz, in 50 Hz increments. The conveyor speed and the scanning frequency of the CLV determine the number of reads theoretically possible per bar code. The higher the scanning frequency, the greater the number of scans possible as the bar code passes the scanner (assuming a constant conveyor speed). With this information, a large number of scans can be checked for agreement of information content. This increases reading reliability. The variable scanning frequency thus enables the reading process to be optimally matched to the conveyor speed and the number of multiple reads required.

Segmentation (Start/Stop Ratio/Absolute Quiet Zone) This allows the user to adapt the CLV to the quiet zone of the bar code label if it is less than the specified 10 times the width of the narrowest bar element or less than .250 in (6 mm).

“Start/Stop Ratio” The start/stop ratio refers to the quiet zones of the bar code label. The scanner can be optimized for the appropriate width of the quiet zones. The numerical values 4-11 are multiples of the minimum bar width. “Auto” is 10 times the width of the minimum bar width.

“Absolute Quiet Zone” This refers to the quiet zones of the bar code label. The CLV can be optimized for the appropriate width of the quiet zones. The numerical value, .004 in to 1 in (1 mm to 25.5 mm), corresponds directly to the actual width of the quiet zone.

Note: This function relies on the Minimum Reading Distance, such that the Minimum Reading Distance setting has to reflect the actual distance from the face of the CLV to the bar code label. If the Minimum Reading Distance setting is not set accordingly, the CLV will not be able to read the label. Therefore, a small or-no-depth of field can be achieved by the CLV in this mode.

CLOCK PULSE

The reading gate is initiated by a clock pulse (trigger device), which synchronizes the scanning process with the occurrence of a printed bar code in the field of view. The CLV accepts these different trigger sources: an external clock pulse generator (hardware trigger), [host device command strings (serial interface)], [internal clock pulse generation (free-running)] and reflector polling (use of a special bar code for automatic triggering). The different trigger sources are shown in Figure 3-19.

Source Clock Pulse

Select one of the following options to configure the source of the clock pulse: “Sensor Input”(active high), is selected if the clock pulse originates from a switching input such as a photoelectric device. “Sensor Input” (active low) is selected when the sensor input is high (+24 V DC, PNP) and brings it to 0 V DC when something is detected, or low (0 V DC) and switches to high (+24 V DC, PNP) when something is detected. [“Active High”, which holds the sensor input low (0 V DC) and switches to high (+24 V DC, PNP) when something is detected.]

Note: If the photoelectric device is powered by the scanner, the “INGND” and “GND” lines need to be connected. Refer again to Figure 2-3 if connecting a photoelectric device directly to the scanner.

“Serial Interface” is selected if the clock pulse originates from a host computer as a serial interface signal via the CLV host interface port (the integrated host command language is set to trigger the scanner).

- If the “Standard” choice is selected, the host command to start the reading gate is: <STX> 21 <ETX>. The host command to stop the reading gate is: <STX> 22 <ETX>. The <STX> and <ETX> are variable host protocol framing characters which are selected under Host Interface; Protocol; Start Char, Stop Char.

- If the “Single Character” choice is selected, the user can select a single character to trigger the reading gate and a single character to stop the reading gate. This character is transmitted to the CLV via the host interface port only. This character does not require the Host Protocol framing “Start Char Receive” and “Stop Char Receive” characters.

“Free-Running” (*010 x (.01); min - 001; max. - 999) is selected to set the CLV to constant reading mode. The user must select a “time out” interval, i.e. the minimum time interval (in seconds) between bar code labels. This “time out” function enables the scanner to discriminate between different bar codes. The reading gate starts when the decoder has found and evaluated the first bar code label, according to prescribed criteria. It ends when no further bar code label is detected within the selected time interval (“time out”). No error string is transmitted in this mode.

“Reflector Polling” If this mode of trigger is selected, the CLV 410 will activate the reading gate automatically if it can not read the unique polling reflector bar code. The CLV 410 looks for this special bar code. If it reads it, it deactivates the laser diode. This happens every 20 scans. Therefore, based on the scan rate, the trigger delay time can be calculated. There are two reflector polling bar codes are packaged with the scanner. One is used for a scanning range up to .5 m and the second one has reflective properties for a scanning range up to 1 m.

End Clock Pulse (Source Cl. Pulse/Timer) This determines when to end the reading gate of the CLV. If “Source Clock Pulse” is selected, the reading gate will end according to the clock pulse condition. If “Timer” is selected, the CLV will end the reading gate automatically after time has elapsed, regardless of the clock pulse method or condition. The timer begins when the CLV is triggered via the clock pulse. Valid Range is 0 to

9.9 seconds. Note: This feature can not be used in the free-running mode of operation.

“No Read” - Active if the CLV has not found a code which matches the defined settings for code type, code length and check

digit at the end of the reading gate. Note: If a code is read but does not meet Multiple Reads criteria (ST=5), the no read condition will not be activated. For this

situation, it is recommended to use a Number of Codes < Minimum Codes instead of “No Read” setting. “Good Read”- Active if the following defined read conditions are fulfilled by the codes read at the end of the reading gate:

- Code type

- Code length

- Number of multiple reads

- Check digit

- Number of codes = minimum number of codes

“Data Pulse”- This output data is being transmitted to the host device. Does not adhere to Timer condition, since it is only active when data is being transmitted.

“Number of Codes < Minimum Codes”- Active if the number of codes read that fulfill the evaluation criteria is less than the specified minimum value. Outputs assigned to switching functions “Good Read” and “No Read” remain active in this case.

“Number of Codes > Maximum Codes” - Active if the number of codes read that fulfill the evaluation criteria is greater than the specified maximum value. Outputs assigned to switching functions “Good Read” and “No Read” remain active in this case.

“No Match” - Active if none of the read codes match the settings for match code 1 or 2. (Prerequisite: Comparison for both code 1 or code 2 activated)

“Match 1” - Activate if at least one of the codes read matches the settings for match code 1. (Prerequisite: Comparison for code 1 activated) “Mismatch 1”- Active if none of the read codes match the settings for match code 1. (Prerequisite: Comparison for code 1 activated and Good Read).

“Match 2” - Active if at least one of the read codes matches the settings for match code 2 (Prerequisite: Comparison for code 2 activated).

“Match 1 or 2” - Active if the settings for match code 1 or the settings for match code 2 or both are fulfilled. “Match 1 and 2” - Active if the settings for both match code 1 and match code 2 are fulfilled. Pulse Duration - (10 x (.01s) 10 ms to 990 ms )

This sets the pulse duration of all discrete outputs. The “00” setting causes the outputs to switch statically, i.e. the outputs change state at the end of the reading gates only.

In addition, if the error status statistic (ST) is being used, a “9” is inserted into the separator of the data output string.

Note: The code comparison is performed at the end of the reading gate. Caution should be taken if the “immediate” output mode is selected for the read result. In this case, a bar code may fulfill the defined criteria but fail the match code comparison. The reading gate then closes prematurely. The “Clock End” output mode under Device Configuration: Clock Pulse: End Clock Pulse menu should be selected.

Teach-In Mode: Dynamic/Static with Pharmacode/Static without Pharmacode The “teach-in” feature allows a user to initiate a simple sequence to have the scanner learn the actual bar code within its scan line, eliminating the need to interface to a computer to re-enter the new match code value. There are two versions of the teach mode, Dynamic and Static. The Static mode can be selected with or without the Pharmacode symbology. Also, if the Static teach-in mode is selected the user can have the scanner counters reset automatically after the teach cycle is complete.

If the Dynamic teach-in mode is selected it activates the Dynamic mode and the user needs to use the following procedure:

Connect the scanner’s input 2 line to a 24 V DC source during the power up cycle of the scanner. This places the scanner into the Teach mode of operation. To teach-in a new match code value, disconnect the input 2 line from the source voltage and then trigger the scanner to take a reading (the bar code to be read must be of a symbology that is already activated in the scanner). The scanner will read the bar code and place the value into the match code 1 position. The final step is to re-connect the input 2 line and the source line; this will save the new value to permanent memory of the scanner and place the scanner into the ready state. The Dynamic teach-in has the following prerequisites:

1. Scanner needs to be powered up with the input 2 line connected to a 24 V DC source

2. The symbologies to be learned need to be activated within the scanner prior to the teach process

3. The scanner needs to be triggered

4. This procedure is only valid for Match Code 1 of the scanner If the “Static” teach-in mode is selected, it is activated and the following procedure applies:

Connect the scanner’s input 2 line to a 24 V DC source during the power up cycle of the scanner. This places the scanner into the Teach mode of operation. To teach-in a new match code value, disconnect the input 2 line from the source voltage. The scanner will activate all symbologies, read the bar code, deactivate all other symbologies, and place the value into the match code 1 position. The final step is to re-connect the input 2 line and the source; this will save the new value to permanent memory of the scanner and place the scanner into the ready state. Static teach-in enhancement has reduced the number of earlier mentioned prerequisites:

1. The symbology of the bar code to be learned does not need to be activated prior to the teach mode process.

2. The scanner self-triggers, eliminating the need for an external trigger to activate the scan line.

3. If reading a pharmacode bar code, it needs to be at least 5 bars long.

4. If reading an Interleaved 2 of 5 bar code, it needs to be at least 4 characters in length. An alternative method is to use the Host Command to activate the teach-in procedure (see below). <STX>2TE<ETX> - activates the teach-in process

<STX>2TS<ETX> - deactivates teach-in process and stores the read value Device ID Number (1-99)

Device ID numbers enable the user to differentiate between several reading stations. Ascanner ’s ID number is sent to the host with the data string and output as part of the separator. See Data String: Separator”. Settings are adjustable in steps of a factor of one; general applications use 01 to 99; The CLX 200 network controller uses 1 to 31. An explanation of ID number assignments in the master/slave mode follows:

Software Configurations

Master/Slave (Stand Alone/Master/Slave/Number of Slaves/Master Timeout) The master/slave mode is a daisy chain configuration of scanners consisting of one master unit and up to seven slave units. The master unit collects and evaluates all the data transmitted by the slave devices in order to sort out redundant data before passing it on to the host device. The master must be closest to the host device and is always automatically assigned 0 as a device ID number. The slave units are automatically assigned consecutive ID numbers based on their physical proximity to the master device.

If “stand alone” is selected, the scanner is programmed to work as an individual unit. If “slave” is selected, the device will function as one of the slave units. With the selection of “master”, the device will be programmed to function as the master device and the user must enter the number of slave devices (count of slaves, 1-7) to be used. The time out determines the maximum transmission time (MTT) for all scanners (slaves) to respond to the master. Valid time out range is 0 to 99.99 seconds.

The MTT can be calculated as follows:

MTT = NS x (11000/Baud x (12 + 20 x MAC + NCC) [ms] + RZ-CLV [ms] NS = Number of slave units MAC = Maximum amount of codes (for slave units) NCC = Number of code characters = Total number of code characters transmitted by a slave

Sum of all codes

RZ-CLV = Reaction time of CLV: 5 ms (roughly estimated value)

Note: The reading gate of the slave units must close before the reading gate of the master unit closes, or data sent after the reading gate of the master unit closes will be lost.

HOST COMMUNICATIONS (Baud Rate/Data and Parity Bits/Stop Bits) The CLV 410 bar code scanner has both RS 232 and RS 422/485 community interfaces available.

Baud Rate (300 - 57,600) Baud rate can vary from 300 to 57,600. When networking via RS 485 interface, a Baud rate of 19,200 Bd is automatically set by selection of “Network Protocol” menu function.

Parity / Data Bits (none-8/odd-7/odd-8/even-7/even-8/space-7/mark-7) “Parity/Data Bits” directs the CLV to transmit data words consisting of individual ASCII characters with selected numbers of data bits, with or without parity check. When networking via RS 485 interface, data format is automatically set at “odd parity/7 data bits” by selection of “Network Protocol” menu function. Combinations are as follows:

Stop Bits (1 or 2) Stop Bits directs the CLV to transmit data words consisting of individual ASCII characters with 1 or 2 stop bits. Default is 1 at standard configuration. When networking via RS 485 interface, one stop bit is automatically set by selecting “Network Protocol” menu function.

DATA STRING

The data string will structure the data output to the host device. The user can select certain parameters that determine what the data string, made up of bar code data and diagnostic reading data, will look like. Refer to Table 4-2 for a description of the contents and location of diagnostic reading data (contained in the header, the separators and/or the terminator). Figure 4-3 shows a sample data string. Refer to the ASCII table in Appendix C for assistance in programming.

Header (up to 10 (Refer to Figures 4-2 and 4-3)) The header can consist of up to 10 characters in any arrangement, or can be suppressed entirely by setting all elements to “00”. If used, the header will always appear in front of the bar code data and the separator (if applicable). The protocol send start character under Host Protocol is the only character that is transmitted before the header.

Any characters from 01 to 7F hex and/or the reading diagnostic statistics MG (average reading evaluation) or CC (number of codes) may be used. Refer to Table 4-2 for descriptions of the statistics and to the ASCII Table in Appendix C.

Figure 3-21 Data String

Software Configurations

Separator (Refer to Figures 3-22, 4-2 and 4-3) Separator directs the CLV to insert selected character sequences into the data string as separators. A separator can consist of up to 10 characters and may appear directly in front of or directly behind the bar code data. The location of the separator is selected at the “Sending Points, S/T Separator” menu choice.

Any characters from 01 to 7F hex and/or the reading diagnostic statistics CA (scan expenditure), CG (identification quality), CK (code continuity), CP (code position), CS (code reliability), ST (error status), ID (code identification), CL (code length), CW (code angle), and Cl (increment counter) may be used. Refer to Table 4-2 for description of the statistics.

Terminator (up to 10 (Refer to Figures 4-2 and 4-3)) Terminator directs the CLV to insert a selected character sequence into the data string as a terminator. The terminator can consist of up to 10 characters and, if selected, will always appear after the bar code data and the separator (if applicable). The protocol send stop character under Host Protocol is the only character sent after the terminator.

Any characters from 01 to 7F hex and/or the reading diagnostic statistics GN (device ID), TT (reading gate duration), CC (number of codes detected), and MG (average reading evaluation) may be used. Default condition is 00 0A hex <CR><IF>. Refer to Table 4-2 for descriptions of the statistics and to the ASCII Table in Appendix C.

Error String

This lets the user create the error string that will be sent to the host in the event of a “no match” or “no read” (if “Error String only” or “Separator and Error String” is activated under “no read format”). Under “Count Characters,” enter the number of characters to be used in the error string. If the sum of characters entered in “contents” does not match this value, the CLV will duplicate the last character until it matches the “Count of Characters” value or limit the number of characters transmitted within the “defined error string.”

Test String

The test string is a repeated confidence or readiness signal sent by the CLV to the host if no bar code data has been transmitted for a specified period. Here the user may define the test string which may consist of up to 15 characters (01 to 1F hex). Characters that may not be used are: 06 hex, 11 hex, 13 hex, 15 hex, and start and stop characters such as 02 hex and 03 hex..

Timer (0 - 9990 s) Here the user may specify a length of time after which the CLV will output a test string to the host if no bar code data has been transmitted. Atime period from 0 to 9990 s (166.5 min) can be selected in increments of 10 s. Default=300 s (5 min)

Note: If used, this automatically changes the “no read format” to “Separator and Error String.”

FORMAT MASK

This function conditions the CLV to transmit only specified characters of a read bar code, providing a way to mask the bar code data transmission to the host device and rearrange the sequence of the data set if required. The user can select up to 35 character positions of a bar code to be transmitted to the host device. Each position can contain up to 2 digits with a numeric value of 0 to 90. Special characters include “--”, “ZZ”, and “OO”. The “--” character is the continuation character, meaning from x to x. The “ZZ” character places a “0” in the output string and the “OO” character in the first position disables the format mask function or terminates the condition at the character position entered.

For example, if only the last five positions of a 10-digit bar code are to be transmitted in the sequence they appear in the bar code label, the first five positions of the Format Mask section would contain 6, 7, 8, 9, 10. The CLV would then only transmit the sixth, seventh, eighth, ninth and tenth positions/characters of the bar code label.

Note: In the “Reading Diagnostics” mode on the terminal interface line, the bar code data is displayed in its original form. In the “Monitor Host” mode, the data output is displayed as defined by the Format Mask function.

Figure 3-23 Format Mask

Wrong Read Format

There are several different ways the CLV can indicate if the scanner gets a wrong read (no read or no match situation):

- Separator(1) only

- Error String(2) only

- Separator(1) and Error String(2)

- No Error String or Separator (1) The separator may be defined in “Host Interface; Output Format”.

(2) The error string may be defined under “error string” and will set “count of characters” to 00.

Status 5 Output

Used when the scanner is able to read something, but cannot fulfill the minimum number of multiple reads the user has programmed. The user may select between “error string,” in which case the CLV will output an error string, or “code string,” in which case the CLV will output the code it was able to read.

Check Max. No. Codes

If “Check Maximum Number Codes” is activated, the CLV will respond with a no read situation if the number of bar codes read exceed the “Max. No. Codes” value entered in the Code Configuration section. If the error status (ST) statistic is activated, an “A” will be transmitted to indicate this condition.

Note: The CLV must be programmed to transmit at “End of Clock Pulse”.

HOST PROTOCOL

Defines handshaking schemes, when data is transmitted and in what order from the CLVto the host device. Also the network mode can be activated. Refer to Appendix C, Table 4 for defaults

Protocol Type (Standard/Network)

Protocol is the method of data exchange between the CLV and the host computer. These settings frame the header, separator, data, and terminator with the selected character values.

Standard (SICK) “Standard (SICK)” refers to the standard SICK protocol for direct connection of the CLV to a host computer via the host port of the CLV. (Refer to Figures 4-2 and 4-3)

“Protocol Send Start Character” directs the CLV to insert a selected character at the start of the data string as a start character for protocol framing. The start character consists of one character and occupies one place in the data string. The character may be 01 to 1F hex. In most cases <STX> = 02 (hex) is used as the start character. This always precedes the header, separator and terminator.

“Protocol Send Stop Character” directs the CLV to insert a selected character at the end of the data string as a stop character for protocol framing. The stop character consists of one character and occupies one place in the data string. The character may be 01 to 1F hex. In most cases <STX> = 03 (hex) is used as a stop character. This always follows the header, separator and terminator.

Note: In order for the CLV utility software to communicate, these values need to be STX and ETX respectively. If not, the software will automatically set the CLV to these values to establish communication. Make sure you reset your requires values during the last download.

Note: In order for a host device to send the host command language sets to the CLV, the command must be preceded by the selected receive start character (STX) and must be followed by the selected receive stop character (ETX).

“Protocol Timeout” directs the CLV to repeat the data string last transmitted within the timeout duration, at request of the host computer. The host must transmit control character <NAK>. Possible settings for timeout have a value from 0 to 9.99 s.

“Protocol X on/X off” directs the CLV to perform data exchange using X ON / X OFF software handshake method. With a “no” response, the handshake method is not activated.

Protocol Block Check directs the CLV to insert the result of a block check in front of the stop character. Protocol Block Check [BCC] consists of an element with two characters, representing a type of cross-sum across all the preceding characters of the data string, including the character of the [START] Section.

[BCC] is determined by XOR linkage of these characters and is transmitted in HEX ASCII form. If [BCC] is inserted in the transmitted data string, the CLV expects the incoming data string to also be equipped with a block check.

Handshake (Nak/Nak Framed/Ack-Nak/Ack-Nak Framed) “Protocol Handshake” allows the user to select which type of handshake method is to be used. Choose between “Nak,” “Nak framed,” “Ack-Nak” or “Ack-Nak framed”.

Network (CLX 200 Standard/CLX 200 Ack-Nak) “CLX 200 Standard” enables the CLV to communicate with the CLX 200 without positive confirmation or repetition request. This must be selected for data exchange with the CLX 200.

“CLX 200 Ack-Nak” enables the CLV to communicate with the CLX 200 in accordance with Ack-Nak protocol. Please refer to the DNC 200 user manual for more information on our network.

This is a customized host interface that will not be used by many users. Contact SICK Optic technical support for detailed information.

Note: If the CLV is in the network mode, the CLV utility software cannot comunicate. Use the icon to establish communication and remember to reset this parameter during the last download.

Sending Points

This function allows the user to determine when the scanner should send bar code data and separators to the host. Refer to Figure 3-28.

(immediately/end of reading/pulse/end of label) If “immediately” is selected, the CLV will send the bar code data to the host immediately after a successful read. If “end of reading pulse” is selected, the CLV will send the bar code data after the clock pulse reading gate has ended. If “end of label” is selected, the CLV will send the bar code data to the host and end the reading gate after the read bar code has moved outside the reading range of the CLV for at least the programmed time value.

Separator Position (After/Before Code) If “After” is selected, the CLV will send the separator string after the code is sent. If “Before” is selected, the separator will be sent before the code data. Refer to Figure 4-2 for examples of each separator position.

Output Code Sorting

With this function, the user can determine whether the scanner will send the bar code data from one reading gate according to the spatial position of the bar code labels (“code position”), the chronological appearance of the codes (“time backward” or “time”), or code length.

Code Length

“Code Length” refers to the ability to scan several bar codes of different lengths and yet provide a constant data string to the host. The CLV transmits the data string of multiple labels to the host device sorted by code length. The order in which they are sent is determined by the code length values entered into the code length list. If the scanner scans more codes than entered in the list, only the codes of the code length list are transmitted. The value for “Max. No. Codes” is no longer relevant. Identical code lengths may be entered into the code length list and sorting is based on time decoded. If there is no matching code for a code length value in this list, the appropriate position is replaced with the error string if the error string is activated. If the programmed error string is longer than code length the defect string is truncated. If the programmed error string is shorter than the code length, the last character of the error string is repeated (see example):

PERCENT EVALUATION

Percent Evaluation is a continuous scanning mode that generates statistical information used mainly for alignment and adjustment (optimal beam position) when installing the CLV. This operating mode is activated only via the terminal emulation screen of CLV Utility Software. Table 3-5 shows three examples of statistics generated in this mode.

This section explains the internal operating data recorded by the CLV and how the counter functions can be reset by the user. Except for the average reading evaluation statistic, operating data are not part of the real-time data set. The user may view this

set of information using the Windows-based CLV Utility Software, if a host device is used, the host, using host command language strings, can query the scanner for this information. Viewing operating data takes the scanner out of the Reading Mode.

The counter collects and records scanner operating statistics regarding accumulated time in operation, number of power-ups, etc.

Operating Hours

By selecting this function, the user can see a running total of the hours the scanner has been in operation.

Power-Up Count

By selecting this function, the user can see a running total of the number of times the scanner has been powered up.

Daily Operating Hours

By selecting this function, the user can see a daily running total of operating hours. This count can be reset by the user via the counter reset function.

Reading Gates

By selecting this function, the user can see how many times a reading gate has been triggered. This count can be reset by the user via the counter reset function.

Good Read

By selecting this function, the user can see how many good reads the scanner has obtained. This count can be reset by the user via the counter reset function.

Average Reading Eval.

The average reading evaluation is a calculated mean value (CGM) of all the values of the identification quality (CG) of reads determined while the reading gate was active. Anew “smoothed” value MG is formed from this value CGM and the previous smoothed value MGold.

This statistic is a real-time statistic (MG) determined during the Reading Mode. It also appears as diagnostic reading data in the header of the output data string. It is calculated by the CLV decoder as explained below:

(a x MGold) - (b x CGM)

MGnew = ———————————-

(a - b)

a=63 b = 1

(63 x MGold) - (1 x CGM)

MGnew = ————————————-

(64) All values are given as percentages. This process is referred to as “exponential smoothing.” When there is a jump in the identification quality CG, the half-value of MG

is reached after 44 reads.

Example: MGold has reached the value 100%. For some unknown reason, new reading gates then always reach the mean value CGM = 50%. In this case, the smoothed value MGnew has dropped to 75% after 44 reads, reaches 67% after a further 44

The value of MG provides an overall indication of the state of the CLV during the previous period and can therefore be used as a quality characteristic for the reading configuration as a whole. Among other things, the reading quality depends on the quality of the printed bar code, the positioning and parameterization of the CLV, contamination of the reading window and any “bouncing” of the reading gate due to an incorrectly set external clock-pulse generator.

Operation

SECTION IV - OPERATION

This section describes functions important to the operation of the CLV scanner following installation and programming. Explained here: initial power up and testing, checking the reading mode, fine optical alignment, function of indicator lights, explanations of messages sent by the CLV, interpretation of output data strings, and description of read quality. At the end of this section is a brief discussion of CLV operation using host command language strings (which will apply to only a few users since most will be working with the integrated menu-driven software or the Windows-based CLV Utility Software).

POWER-UP

Apply supply voltage to the CLV. This initiates the self test. After the self test has been successfully completed, the message “Read Parameters...” will appear. This indicates that the CLV is loading current parameter settings from its memory. The CLV then switches automatically to “Reading Mode” and the green “Device Ready” LED lights, indicating that the scanner is ready for operation in the reading mode.

If the scanner is already powered up and in the Parameterization Mode, access the Reading Mode by selecting “Quit Menu” from the functionality menu.

CHECKING THE READING MODE

If a red laser diode is used as the light source, insert a piece of paper into the path of the beam. The red beam should be visible when the CLV is triggered.

To check the operation of the Reading Mode, perform the following steps: With conveyor facility stopped:

1. Activate reading gate by triggering the trigger source. If an external clock pulse is being used, trigger the device (photoelectric switch, for example,) by covering the reflector. With free-running clocking, the CLV will trigger the reading gate when a bar code label is detected. With external software triggering, a command string from the host device will trigger the reading gate.

2. Present a bar code label to the CLV. If all parameters are correctly set, output data will be transmitted to the host and/or is dis

played using a terminal emulation device on the terminal port.

3. Check that the host device has received the data.

4. If an error message should appear on the display, proceed as in Section V-Maintenance and Troubleshooting.

With conveyor facility in operation: After conveyor facility is powered up, test bar code reading under operating conditions.

1. Pass conveyed products with bar code labels past CLV.

2. If conveyed products are not guided as desired, simulate various settings and observe effect on reading success.

3. Check that the host device has received the data.

4. If an error message should appear on the display, proceed as in Section V “Maintenance and Troubleshooting.”

Operation

SICK Optic-Electronic

Bar Code Scanners

Optical Alignment

Once the trial run has been successfully completed, fine optical alignment of the CLV on the conveyor line can be carried out. Activation of the “Percent Evaluation” mode is recommended to enable the CLV to continuously evaluate the number of valid and invalid reads and indicate the result as a percentage. With this information, the CLV can be optically aligned to obtain the most efficient reading process.

To improve the reading efficiency of the CLV, check the following: Is the minimum bar thickness correctly selected?

Is the reading range on its optimum setting? If the reading distance fluctuates, does it stay within valid limits? Is the reading angle of the scanner acceptable? Is the scanning frequency set for optimum performance? Is the start/stop ratio correct? Is the trigger source triggering properly? For data transmission: are the host interface parameters correctly set? Was the correct function selected for the auxiliary interface?

Indicator LEDs

Figure 4-1 shows the indicator light panel of the CLV. There are four indicator lights: “Device Ready,” “Result,” “Laser On” and “Data.” These are explained below:

The “Device Ready” LED indicates that the scanner is in the reading mode. When the scanner is powered up, the reading mode is automatically activated.

Note: If the “Device Ready” LED does not light upon power-up, this is an indication that the scanner has failed its system self test.

The “Result” LED can be programmed to go on or off based on the following conditions: Good Read, No Read, Match 1, Match 2, Mismatch 1, Mismatch 2, No Match, etc. See Section III-”Parameterization: Device Configuration: Result Output.” Default setting is Good Read.

The “Laser On” LED is activated when a reading gate is triggered and the laser diode is activated.

The “Data” LED is lit when the CLV transmits data to the host device via the host interface.

Operation

Messages in the Reading Mode

During operation, the CLV outputs various messages on the display of the host device or on the screen of an ASCII terminal. Messages can be canceled by pressing any key on the keyboard. Table 4-1 explains the messages that may appear in the Reading Mode.

Read Quality

Bar code data will be sent to the host computer according to evaluation criteria programmed by the user. The paragraphs below explain the difference between what the CLV considers a “good read” and a “wrong read” (called a “no read” here).

Good Read

If all specified evaluation criteria (e.g. number of multiple reads, match code comparison, etc.) have been satisfied, a reading gate is referred to as a “good read” and will be output in the format selected by the user.

No Read

If all of the selected evaluation criteria (e.g. multiple reads, match code, etc.) have not been satisfied, or if the scanner can not detect any bar codes, a reading gate is considered unsuccessful (“wrong read”). In the event of a “no read,” the CLV can output a user-definable error string message that can consist of either the (user-definable) separator only, the (user-definable) error string only, both the separator and the error string, or nothing at all. If the scanner is able to read something but can not fulfill the minimum number of multiple reads specified by the user, the CLV can output the message “ST=5” with either an error string or the code the scanner was able to read. To program the output format of a no read situation, see Section III, “Output Format: Wrong Read.”

Operation

SICK Optic-Electronic

Bar Code Scanners

OUTPUT INTERPRETATION

The output of a read consists of the decoded content of up to three different bar codes, plus diagnostic reading data. Diagnostic reading data is described separately in detail. The bar code data is carried in a structured string as shown in Figure 4-2. The string consists of elements combined to form the following blocks:

Start character Header (diagnostic reading data and selectable constants) Bar code data Separators (diagnostic reading data and selectable constants) Terminator (diagnostic reading data and selectable constants) Stop character

The user may specify form and content of the data string to be sent to the host (refer to Section III, “Output Format”). The auxiliary interface, operating in the “Monitor Host” mode, displays the data string configured for use with the host interface. Two examples of decoded bar code data are given in Figure 4-2.

In Example 1, the protocol start and stop characters are used to frame the information with start of text and end of text ASCII control characters. The terminator provides the carriage return and line feed control characters.

In Example 2, the protocol framing characters are not used. The data transmitted along with two sets of statistics delimited by a comma. The statistics and commas are selected within the separator field. At the end of the string, a carriage return and line feed are included as part of the terminator field.

Operation

DIAGNOSTIC READING DATA

The CLV bar code scanner is able to continuously generate diagnostic reading data and integrate this into the data output string for evaluation by the user. Diagnostic reading data is transmitted in the header, separators and/or terminator of a data string. The user is able to define the content of each of these elements of the data string in the Parameterization Mode (see Section III, “Parameterization: Host Interface: Output Format”). Table 4-1 defines the statistics available to the user and provides information on the output location of each statistic. Figure 4-3 shows how the statistics are calculated.

Error Status ST • Indicates cause of unsuccessful read diagnosed For every Separator –

by CLV. Eight different error status codes bar code label are available: in a single ST=A: Programmed maximum number of codes reading gate

has been exceeded ST=0: Good read ST=1: Wrong check digit ST=2: No read ST=3: System error ST=5: Number of multiple reads specified have

not been fulfilled

ST=6: Master unit does not identify the proper

number of slave units

ST=7: Source of bar code data is auxiliary input

via auxiliary interface ST=8: Data loss in networking operation ST=9: Match code filter stopped transmission

• The error status is a criterion for the insertion of code error strings (space savers) in the host interface data string.

Code I D • Provides code letter for assignment of bar code – Identification contents to type of code symbology from which

it comes, e.g, “a”=Codabar

Code Length CL • Indicates number of digits of decoded bar code –

contents Serves to indicate appropriate data field in data string; permits further data processing, even with free code lengths

Code Position CP • Indicates position on scanning line at which bar 3-2

code label is detected (position of first dark bar) Numerical values from 000 to 100 are used to designate relative position Resolution is 10°.

• Line scanner example: several bar code labels arranged consecutively in a row receive different position designations. Codes with identical contents can therefore be detected as nonredundant and be output

Operation Using Host Command Language Strings

Table 4-3 shows an example of the use of command strings from the host interface to the CLV. If using a host device with command strings, refer to the CLV Command Language Guide (a SICK Optic-Electronic publication) for information regarding other command strings.

Similar to the menu-assisted approach, all parameters (except data format of the host interface) can be customized as described. With a host device, for example, the user can program each reading station of a conveyor installation individually, and reinitialize them following start-up.

Troubleshooting

SECTION V -MAINTENANCE AND TROUBLESHOOTING

The CLV Bar Code Scanner is essentially maintenance-free. This section will cover preventive maintenance measures such as cleaning of the optical surfaces and the system self test. Error messages that can occur in the Parameterization, Reading, and Percent Evaluation modes are also discussed here.

CLEANING OPTICAL SURFACES

Depending on the operating environment of the CLV (amount of dust, humidity, etc.), these optical surfaces should be cleaned on a regular basis:

• CLV reading window

• Exit window of photoelectric switch, if applicable, and the surface of the reflector (follow sensor instructions) CAUTION: No aggressive scouring agents or solvents should be used. These can damage glass surface of reading window or

plastic surfaces.

CLV Reading Window

If the read quality of a consistently good bar code print is low, this could indicate that the CLV window is dirty. A soft, lint-free cloth dampened with a mild water-soluble cleaning agent is recommended for cleaning. Do not use a scouring motion when cleaning.

Exit Window of Photoelectric Switch

If an external hardware trigger such as a photoelectric switch is being used as a clocking method, the exit window of the sensor should be cleaned according to the manufacturer’s instructions.

CLV SYSTEM SELF TEST

The system self test is a functional test of the CLV system electronics, the memory, and the visible laser diode. If the scanner fails its self test, the reading mode will not be activated and the “Device Ready” LED will not light.

ERROR MESSAGES

If errors occur in a selected operating mode, the CLV signals the diagnosed error via the auxiliary interface for indication at the display of the host device. Some error messages are also output in the host interface data string. Tables 5-1 through 5-3 list the error messages that may appear in the Parameterization, Reading, and Percent Evaluation modes and include information on the possible time of occurrence, meaning, possible cause, and steps that should be taken by the user to correct the condition.
