3 GREEN LED - STABILITY INDICATOR: This led is on when the level of the output signal and the alignment of the photoelectric sensors are in the optimum position. In the case that the led is off this indicates that the lens is obscured or for the types with direct reflection a possible alteration of the dimension or color of the object to be detected.

4 YELLOW LED - OPERATION INDICATOR: This led is on when the object to be detected enters the sensing range of the photocell giving output signals.
