Safety information
2.1
Intended use
The image-based code reader Lector621 is an intelligent SICK-4Dpro sensor.
The device is used for automatic, stationary identification and decoding of codes on
moving or stationary objects. The device reads all commonly used 1D codes (bar codes,
stacked codes) and 2D codes (matrix codes). In read mode, the device transmits the
read results via a host interface to a higher-level computer (e.g. PLC) for further central‐
ized processing.
The device is designed for use in industrial and logistics applications in its two variant
lines
Lector621
and
Lector621 ECO
. The device meets the applicable requirements for
industrial robustness, interfaces and data processing.
SICK AG assumes no liability for losses or damage arising from the use of the product,
either directly or indirectly. This applies in particular to use of the product that does not
conform to its intended purpose and is not described in this documentation.
2.1.1
Conditions for specified enclosure rating
To ensure compliance with the specified IP65 enclosure rating of the device during
operation, the following requirements must be met: If these requirements are not met,
the device does not fulfill any specified enclosure rating.
Lector621
•
The cables plugged into the two electrical M12 connections must be screwed on
tightly.
•
Any electrical M12 connections (Ethernet connection) that are not being used
must be sealed with a tightly-fastened protective cap (as in the delivery condition).
•
The black cover (flap) on the rear of the device must be flush with the device and
screwed tight.
Lector621 ECO
•
The D-Sub male connector of the connecting cable must be tightly screwed to the
contacted female connector.
•
If an extension cable is used, a corresponding rubber seal (SICK accessory) must
be fitted between the two D-Sub plug connectors. The plug connectors must be
screwed together. You can find a suitable IP65 rubber seal online at:
•
The black cover (flap) on the rear of the device must be flush with the device and
screwed tight.
NOTICE
Operate the device with open black cover only for a short time for the following tasks
as required:
•
Type-dependent: inserting or removing the optional memory card
•
Temporary use of the USB interface as a service interface
During this time, protect the device against moisture and dust.
2.1.2
Using the USB interface
NOTE
The USB interface of the device is used in industrial environments only as a service
interface for temporary use (e.g. for configuration, troubleshooting). Permanent use in
operational use of the system as a host interface is not intended.
