1)
If external device monitoring is configured and there is an EDM warning, diagnostic LED 1 flashes, while the other diagnostic LEDs 2, 3 and
4 indicate the alignment quality. If there is an error on the reset pushbutton, diagnostic LED 4 flashes, while the other diagnostic LEDs 1, 2
and 3 indicate the alignment quality.
2)
If the protective fields are very wide, there is a possibility that diagnostic LED 4 does not light up, even with optimal alignment.
