Additional components
Heater
The CLV can be permanently equipped with a heater for applications involving temperatures
up to max. –35
°
C (e. g. in a freezer).
The design, technical data, and power-up behavior of the CLV are described in
External parameter memory
The external parameter memory is located in a connector cover which, when mounted,
covers the two electrical terminals on the CLV (IP 65). The parameter memory saves you
time when a CLV is replaced locally by providing a copy of the current parameter set. In other
words, you do not have to configure the new device.
For information on applications and operating procedures, see
operating the external parameter memory, Page 10-34

Indicators and control elements
3.3.1
Control elements
The CLV is operated and configured via the terminal interface (auxiliary interface) using the
"CLV-Setup" program or using command strings sent via the host interface/terminal inter-
face. A variety of parameter options allow you to adapt the device to a wide range of appli-
cations.
The following can be defined:
•
The configuration of the code types
•
The read, evaluation, and output properties
•
The communication parameters of the host interface
•
The structure of the data output string for "Good Read" and "No Read" on the host in-
terface
•
The function of the terminal interface

Function of the LEDs
Four LEDs indicate the operating status, activity of the laser diode, reading result status, and
data transfer on the host interface. The LEDs are located on the rear of the device (
If the optional external parameter memory is connected, the LEDs also indicate whether the
memory was successfully accessed.
