LED illuminates. Empty cells mean that the LED lights up, flashes, or is off.
After the configuration is displayed, diagnostic LEDs 1, 2, 3 and 4 indicate the align‐
ment quality. Additionally, the synchronization status of the topmost and bottommost
beams of the safety light curtain are displayed by means of diagnostic LEDs 5 and 6 as
well as 7 and 8.
If the configuration was changed, the diagnostic LEDs flash white for 3 s upon activa‐
tion.
Once the safety light curtain is aligned and the protective field is clear (field indicator:
flashing yellow or lit up green), the alignment quality display switches off after a certain
period of time.
