Installation of external components
5.5.1
Installing connection module CDB620 or CDM420
Depending on the application, you can install either connection module CDB620 or
CDM420. The installation process is the same for both modules.
Important
If the PC with the SOPAS-ET configuration software accesses the bar code scanner's auxili-
ary interface (RS-232; 57.6 kbd) via the connection module, the connection module should
not be installed more than 3 m (9.84 ft) cable lengths away from the bar code scanner.
1. Install the connection module close to the bar code scanner.
2. Install the connection module in such a way that the opened device can be accessed
at any time.
5.5.2
Installing the external reading pulse sensor
If the bar code scanner is triggered by an external reading pulse sensor (photoelectric reflex
switch), the sensor has to be installed close to the bar code scanner.
Fig. 5-8:
Line scanner: Installation example for positioning the external reading pulse sensor
The sensor's installation location depends on the distance (a) of the bar code to the front
edge of the object. Depending on the application, the sensor should be attached in such a
way that bar codes on different sized objects can be fully read during the evaluation (rea-
ding gate).
Important
For detailed information about installation and electrical installation, see the operating ins-
tructions "Connection Module CDB620“ (no. 8012119, German/English) or "Connection
Module CDM420-0001“ (no. 8010004, German/English).
Important
The SICK catalog "SENSICK Sensoren for Automation" (order no. 8006530, English) con-
tains a large selection of photoelectric reflex switches and photoelectric proximity switches
as well as accessories (holders, connection cables).
