➢
When selecting the test rod, use the identification plate of the receiver with the resolution
information as a guideline.
➢
If the internal start/restart interlock function is selected, but the AOPD is released, LED1
lights up green on the SD4R-E Receiver. When the test rod is inserted, LED1 switches to
red, and the restart interlock locks. During the testing procedure, LED2 must not light up
at any position of the protective field. Only after the test rod has been taken out of the
protective field does LED2 light up yellow (restart interlock locked).
➢
If the AOPD is being operated without the internal start/restart interlock, it is sufficient to
watch LED1 on the receiver during the testing procedure. When the test rod is inserted
into the protective field, this LED1 must switch from "green" to "red" and must not switch
back to "green" at any point during the test.
Warning!
If the test does not provide the desired result, the cause could be a protective field height
that is too low or reflections from reflective metals or tools brought into the area. In this
case the installation of the Safety Light Curtain must be checked by a specialist. If the
cause cannot be clearly defined and remedied, the machine or system may not be used!
