3.2 Alignment Procedure
When the safety barrier has been mounted, optical alignment of transmitter and receiver is made as
follows:
• Disconnect the barrier's power supply. Open the test/reset (see 5.1).
• Restore the barrier's power supply. The test/reset can then be closed again.
• Make sure that both units are in level, vertical and directed towards each other. Adjust by turning the
transmitter, left and right, until LED 2 and 5 of the receiver are lit. Turn the transmitter both ways to f i nd
the outermost positions, return the transmitter to the midpoint. The barrier is correctly aligned when the
LED 3 is constantly lit even if one of the prof i les is somewhat turned.
• After aligning the barrier, secure the screws f i rmly.
• Disconnect the power supply.
• Restore the barrier's power supply (with the test/reset contact closed). If the safety area is clear and
automatic reset is chosen, the barrier will immediately enter operating mode, i.e. the OSSD outputs
are activated and the LED 1 and 3 are lit. If manual reset is chosen, test/reset must be pressed and
released before the OSSD outputs are activated.
• Complete the checks described in section 13 "Final Checks" and 16 "Routine Checks and Mainte-
nance".
