Installation
4.2.4 Replacing the laser warning label
If necessary, replace the laser warning label in GB English/US English on the CLV with the
required language (
Fig. 4-1).
The device is delivered with a set of laser warnings in:
• German/US English
• French/US English
See also Chapter 2.3 General safety instructions and protection measures, Page 2-2.
4.2.5 Selecting the installation location
When you select the installation location, the distance between the CLV and the host and
between the CLV and the bar code are important.
Distance between the CLV and the host
The CLV can be installed without a connection to the SICK CAN Scanner Network or to a bus
connection max.
1,200 m (3,936.96 ft) away from the host. The distance which can be
achieved depends on the selected model of the host interface and the set data transfer
rate, however. See
Table 5-2, Page 5-3.
Distance between the CLV and the CDB 420 or CDM 420 connection module
The CDB 420 or CDM 420 connection module must not be located further than 10 m
(32.8 ft) away from the CLV, since the "CLV Setup" program on the PC accesses the
terminal interface of the CLV via this module (RS 232).
4.2.6 Mounting accessories
The CLV is mounted with the help of two tapped blind holes (M4) located on the bottom
narrow side of the device.
Fig. 4-2 shows the position of the threaded hole for both housing
models. The complete dimensions of the CLV housing are shown in Fig. 9-1, Page 9-3.
