– Test and Maintenance
Testing the safety light curtain with the test piece
The test procedure should
be carried out frequently as
indicated by the risk
assessment for the
particular installation.
A test must be carried out
at the initial installation and
prior to the machine start-
up.
Smartscan Ltd
recommends the test
should be carried out daily.
Any changes to the
configuration of the safety
light curtain must be
followed by testing to
check the system is still
working correctly.
Regular function checking
of the safety light curtain as
well as at initial installation
is required as part of the
test and maintenance
process.
The operating instructions
for the safety light curtain
and machine must be
made available for the operator and those responsible for installation,
maintenance and safety control at all times.
To test the safety light curtain power it up and activate the output switching
circuits (OSSDs) to an ON condition.
Insert a test piece of appropriate size into the light curtain detection zone, at the
bottom, 150mm from the transmitter unit. At this point the output switches will turn
OFF. Sweep the test piece up through the detection zone parallel to the
transmitter. Now sweep the test piece down through the detection zone equal
distance between the transmitter and receiver. Now sweep the test piece up
through the detection zone 150mm and parallel to the receiver unit. At no time
during these tests should the output switches turn ON.
