Installing external components
4.4.1
Installing the CDB 420 or CDM 420 Connection Module
1.
Install the CDB 420 or CDM 420 Connection Module near the ICR. The distance
between the CDB 420 or CDM 420 and ICR must not exceed 10 m (32.8 ft).
2.
Install the CDB 420 or CDM 420 in such a way that the device can be accessed when
opened. The auxiliary interface of the ICR, used for parameterizing/diagnosis, is
accessed via the internal “Aux“ connector.
Detailed information on the installation and electrical installation procedures is provided in
the
“CDB 420 Connection Module“ Operating Instructions (order no. 8 010 001, German/
English version)
respectively in the
“CDM 420 Connection Module“ Operating Instructions
(order no. 8 010 004, German/English version).
4.4.2
Installing the external reading pulse sensor
If the ICR is triggered by an external reading pulse sensor, the sensor must be installed in
the vicinity of the ICR. The “Sensor 1“ switching input is selected as the default trigger source
for this trigger type.
shows two examples of where a photoelectric reflex switch can be installed. This
depends on the distance a from the code to the front of the object. Depending on the
application, you may need to attach the sensor in such a way that codes on objects of
different sizes can be read completely during the reading interval (
no conveyor movement
).
1.
Attach the reading pulse sensor to the installation location.
2.
Connect the reading pulse sensor to the “Sensor 1“ switching input of the ICR via the
CDB 420 or CDM 420 Connection Module (see
Chapter 5.5.8 “Connecting the “Sensor
1“ switching input“, Page 5-13
3.
Connect the ICR to the CDB 420 or CDM 420 Connection Module and switch on the
power supply to the module (see
Chapter 5.5.3 “Connecting the power supply“,
).
After the ICR has started, it emits a tone to indicate that the self-test was successful.
After a short while, it outputs two consecutive tones to indicate that it has switched to
Reading mode. The “Device Ready“ LED lights up.
4.
Connect the PC to the auxiliary interface of the ICR. For this purpose, connect a 3-core
RS 232 data cable (null modem cable) to the internal 9-pin “Aux“ plug of the module.
(see
Chapter 5.5.7 “Connecting the PC“, Page 5-12
