3. System requirements

4. Laser rotection

Laser radiation!

The radiation emitted by the laser diode (red or IR light) on the CLV 10 is harmful to

the human eye. For this reason, do not look directly into the laser beam.

Opening the housing while the device is in operation does not prevent the laser diode

from being activated by the reading pulse.

The maximum output power of the laser beam at the reading window is 1

2 mW.

The CLV, therefore, is assigned to protection class 2.

Laser radiation, do not stare into the beam, class 2 laser roduct.

Max. out ut radiation: 1

. 2 mW (223 µµ

µµ

µs), emitted wavelength: 670 nm

See Section 15 for further safety instructions!

via the EDIT READING PULSE field on the DEVICE CONFIGURATION card of the user interface

and download it to the CLV.

8. 5 Connecting the interfaces

All of the interfaces are routed via the 15-pin D Sub HD connector À (Table 3).

8. 5. 1 Connecting the host interface

The CLV is equipped with two host interfaces (RS 232 and RS 22/ 85). One of

these must be selected for data communication with the host/PC. If the RS 232

interface is not connected to the host, it can be used exclusively to monitor data

traffic on the parallel RS 22/ 82 interface.

TIP:

The internal modules of the CLV may be damaged irreparably if the data interface

is connected incorreclty.

ØConnect the host interface of the CLV to the host in accordance with the EMC

requirements using shielded cables(Fig. )

ØTo prevent interference, do not lay the data cables over a long distance parallel

to the power supply and motor cables, e.g. in cable ducts

ØApply the shield on one side (SICK recommendation)

Recommended max. cable lengths between the CLV and host:

By reading in profile bar code nos. 11 and 12 (Section 10.2 Default setting), you can

define the above default settings temporarily with a different parameter set to allow

the PC to communicate with the CLV.

8. 5. 2 Connecting the functional interfaces

Sensor 1 switching in ut

In order to trigger a reading process, the CLV requires a suitable clock pulse in

Reading mode that signals the presence of a conveyor object in the reading field.

The clock pulse generates the reading interval (time window for evaluation) internally

in the CLV. In the default setting, the reading pulse is supplied by means of internal,

continuous reflector polling (see Section 9.2).

If an external sensor (e.g. photoelectric switch, switch) is to notify the CLV of the

presence of a conveyor object, the following steps must be performed:

ØConnect the sensor to the CLV as shown in Fig. 5
