Follow the steps below to align the units:
•
Hold the receiver (RX) steady and align the emitter (TX) so that the
yellow “LOW ALIGN” LED lights up, confirming that the first lower
beam has been aligned correctly.
•
Rotate the emitter (TX) until the yellow “HIGH ALIGN” LED is also
lit. The “SAFE/BREAK” LED switches from red (BREAK) to green
(SAFE).
NOTE:
Make sure that the “SAFE/BREAK” LED is constantly
green.
•
With a few small movements, define the area in which the
“SAFE/BREAK” LED is constantly green; do this first with one unit
and then with the other. Place both units in the centre of this area.
•
Use the pins and/or mounting brackets to firmly secure both the
units.
•
Disconnect the power supply to the safety light curtain.
•
Reconnect the power supply.
•
Make sure that the green “POWER ON” LED on the receiver (RX)
is lit (light beams are clear, “SAFE” operating status) and that this
switches to red if just a single beam is interrupted (detected object,
“BREAK” operating status).
•
Perform this test using a cylindrical “test rod”, the diameter of
which should correspond to the resolution of the device (14 mm, 20
mm, 30 mm or 35 mm). The test rod is available as an accessory.
NOTE:
If you pass the test rod from top to bottom along the
length of the whole sensing area, at any distance from
either unit, the “SAFE/BREAK” LED must be constantly
red. We recommend that you perform this test daily.
