Chapter 4 Operating Instructions

CLV490 Bar Code Scanner

Installation

ground“ must be selected. Alternatively a fixed focus position can be set. See Chapter c)

Parameterizing focus control, Page 6-12.

Installing the reading pulse sensor for start/stop mode:

1. Mount the reading pulse sensor.

2. Connect the reading pulse sensor to the "Sensor (1)" switching input of the CLV490 via

the CDB420 or CDM490 Connection Module (see Chapter 5.5.7 Connecting the

"Sensor" switching input, Page 5-22).

3. Connect the CLV490 to the CDB420 or CDM490 Connection Module and switch on

the power supply to the module (see Chapter 5.5.3 Connecting the supply voltage,

Page 5-18).

After it has started, the CLV490 confirms that the self-test was successfull and switches

to Reading mode ("Device Ready" LED lights up).

4. Connect the PC to the auxiliary interface of CLV490. To do so, connect a 3-core RS 232

data cable (null modem cable) to the internal 9-pin "Aux" plug of the CDB420 or

CDM490 (see Chapter 5.5.5 Connecting the CAN interface, Page 5-21).

5. Start Windows and the "CLV-Setup" program (see Chapter 10.6.3 Starting CLV-Setup,

Page 10-46).

6. From the VIEW menu, choose READING MODE.

The Terminal Emulator is launched. The CLV490 is in Reading mode (default: SMART

decoder).

Monitor the reading result during each of the subsequent steps!

Line scanner with oscillating mirror:

In default setting, the CLV490 deflects the scan line (default setting) about the fixed po-

sition CW = 50 with a frequency of 1 Hz at a max. angle of ±20° (±40 CW).

50 CW corresponds to an angle of emergence of 105°.

7. Move objects with bar codes into the CLV490 reading field manually under realistic con-

ditions and check whether the reading result and trigger pulse are correct.

8. Repeat the procedure with the conveyor switched on. Check whether the reading

procedure is synchronized with the objects.

Parameterizing an external sensor as a trigger source:

These settings are not required if the CLV490 is operated with the default configuration.

1. Choose the DEVICE CONFIGURATION tab.

2. In the R

EADING TRIGGER SOURCE section click the option SENSOR INPUT (ACTIVE HIGH).

3. Download the settings to the CLV490 by clicking in the toolbar.

The D

OWNLOAD PARAMETERS dialog box is then displayed.

4. Confirm the dialog box by choosing P

ERMANENT.

The CLV490 operates with the "Sensor" switching input as an external trigger source.

The reading pulse starts when the input is energized (high).

4.4.3 Installing incremental encoder

In the reading mode "Tracking", an incremental encoder is required for determining which

bar codes belong to which objects. The encoder is also required to separate bar codes of

the same symbology with identical content.

1. Install the incremental encoder (e. g. no. 2022714) near the CLV490 but in front of it,

preferably against the direction of the conveyor belt. The increment pulses must

originate from the area of the conveyor belt which the CLV490 is reading.
