Safety information
2.4 Quick stop and quick restart
2.4.1 Switching off the CLV
Switch off the power supply or remove the CLV connector from the connection module.
This can result in loss of the following (at the most):
• the application-specific parameter set, if it was only stored temporarily in the CLV
• the last reading result
• daily operating data
(operating hours counter, trigger count, no. of good reads, no. of no reads, maximum
duration trigger, minimum duration trigger, matchcode 1, matchcode 2, no match)
2.4.2 Restarting the CLV
Switch on the supply voltage or reattach the connector to the connection module.
The CLV resumes operation with the parameter set that was last stored permanently
and resets the daily operating data.
2.5 Environmental information
The CLV is designed to cause minimum impact on the environment. It does not contain any
silicone-based materials on the hosuing surface and, therefore, does not represent any
problems for e.g. paint sprayers in paint shops.
2.5.1 Power requirements
The power requirements are particularly low:
• the CLV 420/421/422 line/raster scanners have a max. power consumption of 3.5 W
The value is given for devices with disconnected switching outputs.
2.5.2 Disposal after final decommissioning
Always dispose of unusable or irreparable devices in a manner that is not harmful to the
environment and in accordance with the applicable national waste disposal regulations. The
CLV can be separated into recyclable secondary raw materials and special-category waste
(electronic scrap). See
Chapter 7.3 Disposal, Page 7-2.
At present, SICK AG does not accept any unusable or irreparable devices.
