5 SICK LSI Technical Description - 06/98
2 Conditions of Use
The LSI is a device designed to protect people and property. It is
intended to monitor hazardous areas in enclosed spaces in
conjunction with one or more PLS laser scanners.
Observe the instructions relating to permitted use. SICK cannot
be held liable for damage arising from use of the LSI other than
stipulated.
•
Be sure to follow the instructions given in the technical
description of the PLS laser scanner! It contains important
information on safe operation of the LSI system.
• Install the LSI in a dry location and protect the unit against
dirt and damage (IP 54 switch cabinet).
• Route all wires and connecting cables such that they are
protected against damage.
•
Ensure that the connected controller and all other devices
also have the necessary safety integrity. Make sure that the
controller guarantees prompt switching between the
monitoring cases. Note that there may already be someone
in the protective field when the switch occurs. Safe
protection is guaranteed only by prompt switching (that is,
before the danger arises for the person at this point).
• Make sure that the input circuitry matches the expected
ambient conditions, in order to prevent interference and
resulting errors in monitoring case switching.
•
Make sure that the response time of the LSI system is
adequate in every monitoring case to protect the hazardous
area (the response time of the LSI depends on the multiple
evaluation, and is pre-set in the PLS/LSI user software).
•
Make sure that no obstacles in the monitoring area can
obstruct the fields of vision of the connected PLS units or
cause shadows.
Where there are unavoidable areas of shadow, check
whether they present any risk. Take precautions as
necessary.
• Keep the monitoring area free of smoke, fog, steam and
other air pollution. The functioning of the LSI system may
otherwise be impaired, and error shutdowns may occur.
•
In mounting, installation and use of the LSI, observe the
standards and regulations applicable in your country. The
appendix presents a summary of the most important
regulations.
• For programming of the monitoring areas and monitoring
cases, take note of the description of the PLS/LSI user
software in section 9. This describes how to connect the LSI
to a PC and how to work with the user software.
•
If you deploy the LSI for vehicle protection, note that it can
only be used on vehicles with an electric motor.
When using the LSI on materials handling equipment in
narrow aisles be sure to follow the instructions given in the
technical description of the relevant PLS.
If using the LSI with PLS type 101-316, note that the
response time of the LSI is not programmable, but is fixed at
270 ms.
•
The LSI must be disposed of in a proper and environmentally
friendly manner at the end of its useful service life.
