5 ALIGNMENT
The emitter (TX) and receiver (RX) 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 emitter (TX) meet the optical axes of the corresponding
elements on the receiver (RX).
Two yellow LEDs on the receiver (RX), “HIGH ALIGN” and “LOW
ALIGN”, simplify the alignment process.
5.1 Alignment instructions
Once the mechanical assembly and the electrical connections have
been completed, the safety light curtain can be aligned as described
below:
• Disconnect the power supply to the safety light curtain.
• Press the TEST/START button and keep it held down (opens the
contact).
• Reconnect the power supply.
• You can now release the TEST/RESET button.
• On the emitter (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 is one of the following:
- BREAK Status: Green LED "POWER ON" is lit and LED
"SAFE/BREAK" lights up red (BREAK).
-> The safety light curtain is not aligned correctly.
- SAFE Status: Green LED "POWER ON" is lit and LED
"SAFE/BREAK" lights up green. The yellow LEDs “HIGH
ALIGN” and “LOW ALIGN” are lit.
-> The safety light curtain is aligned correctly.
