Target

Note: Due to the detection method, targets traveling horizontal to the sensor’s optics are detected. Targets traveling vertically may not be accurately detected. For reliable background suppression, a minimum separation distance of 6 mm (0.24 in.) is recommended between the target and the backgrounds.

		OFF	Output de-energized

Output	Yellow	ON	Output energized
		Flashing	Output SCP active (DC models only)

		OFF	Margin <2.5

Margin	Orange	ON	Margin >2.5

Note: For DC models, output and margin LEDs alternate flashing when SCP is active.

Sensor Alignment

The orange LED is an alignment aid which indicates that a margin of 2.5 has been reached. This means that the sensor is receiving at least 2.5 times the signal strength back from the target needed to trigger an output signal. In general, it is desirable to have a higher margin to help overcome any deteriorating environmental conditions, i.e., dust build-up on the sensor’s lens. When aligning the sensor, the best performance can be obtained if this margin indicator is illuminated with the target in place.

When aligning diffuse mode sensors, ensure that the sensitivity be set at its maximum setting using the single-turn adjustment knob on the front panel. Pan the sensor left, right, up, and down to center the beam on the target. It may then be necessary to decrease this setting to prevent the sensor from detecting a background object. If this problem persists, the application will require the use of a background suppression, sharp cutoff diffuse, or retroreflective sensing mode.
