5. ALIGNMENT
The transmitter and receiver must be aligned to ensure the proper
function of the device.
Perfect alignment is achieved when the optical axes of the first and last
beam from the transmitter meet the optical axes of the corresponding
elements on the receiver.
Two yellow LEDs on the receiver, "HIGH ALIGN" and "LOW ALIGN",
simplify the alignment process.

Correct alignment procedure
Once the mechanical assembly and the electrical connections have
been completed as described in the previous sections, the light curtain
can be aligned as described below:
•
Disconnect the power supply to the PSEN safety device.
•
Press the TEST/START button and keep it held down (opens the
contact).
•
Reconnect the power supply.
•
You can now release the TEST/START button.
•
On the transmitter (TX), ensure that the green LED "POWER ON"
and the yellow LED "SAFE" are lit. This confirms that the
transmitter is operating correctly.
•
Make sure that the status of the receiver (RX) is one of the
following:
•
BREAK Status: Green LED "POWER ON" is lit and LED
"SAFE/BREAK" lights up red (BREAK).
-> the units are not aligned.
•
SAFE Status: Green LED "POWER ON" is lit and LED
"SAFE/BREAK" lights up green (SAFE). The two yellow LEDs
"HIGH ALIGN" and "LOW ALIGN" are both lit.
-> the units are aligned.
