Operation
FUZZY LOGIC MUTUAL INTERFERENCE PREVENTION FUNCTION
(FOR E3S-CR
E3S-CD
ONLY)
photoelectric sensors installed side side, each Sensor influenced malfunction) light emitted from other sensors. This known mutual interference. fuzzy logic mutual interference prevention function E3S-C enables E3S-C monitor light interference over certain period time. Before E3S-C starts emitting light, E3S-C retrieves intensity frequency surrounding light interference data. Using this data, E3S-C calculates, with fuzzy inference, risk E3S-C malfunctioning controls timing E3S-C's light emission.
When risk low, E3S-C waits until there light interference emits light.

Emission pattern
When risk high, E3S-C emits light between each light interference moment.

Procedure
Place target desired sensing distance. sensitivity adjuster minimum scale position, gradually increase sensitivity turning sensitivity adjuster clockwise until Light Incident indicator (red LED) turns Position designates point which turned
Remove target. Starting from maximum scale position, gradually decrease sensitivity turning sensitivity adjuster counterclockwise until Light Incident indicator (red LED) turns OFF. Position designates point which turned OFF.
sensitivity indicator position between Positions some cases, Positions opposite above example). photoelectric sensor will then work normally stability indicator (green) with without target. lit, stable operation cannot guaranteed,in which case different detection method should applied.
Unlike conventional photoelectric sensors, variation sensitivity among several E3S-C photoelectric sensors minimal. This means sensitivity adjusted only single photoelectric sensor, then adjusters other E3S-C photoelectric sensors same scale position. There should need adjust sensitivity each photoelectric sensor individually.
