9.2. Inspections
The light curtain must, depending on the valid regu-
lations, be periodically tested by qualified and
trained persons, so that unallowed manipulations
and non-conform modifications may be detected.
The function of the light curtain can be tested with
the supplied test rod, which has a diameter corre-
sponding to the resolution of the light curtain. The
status is indicated through the LED display in the
CEDES Safe2+ or Safe4 light curtain.
Functional Test
The function of the light curtain can be tested using
the test rod, (Figure 15), which has a diameter cor-
responding to the resolution of the light curtain. The
status is displayed at the 3 LED at the emitter re-
spective receiver. The status can be easily read
from the trouble shooting labels "Emitter Status" and
"Receiver Status" (table 1 and 2, page 13).
9.3. Decommissioning
The safety light curtain may only be removed, if the
machinery or assembly line will be closed defini-
tively. This has to be done by removing the mains
supply from the machinery. It must be impossible to
bring the machinery into operation without using
tools.
The light curtain can be reused provided the current
regulations are taken into consideration.
If the light curtain has to be disposed, it can easily
be disassembled and recycled using state of the art
recycling technology and following current disposal
regulation. It does not contain harmful materials
except small quantities of materials used in elec-
tronic PCBs.
