1) Light Output is on BK wire/Pin 4 for Diffuse sensors and on WH wire/Pin 2 for Retroreflective and thru-beam sensors.
For E71-P/C (polarized retroreflective and clear object) models…
– Position sensor and reflector on opposite sides.
– Turn the sensitivity dial to maximum.
– Find the point at which the output LED (yellow) is switched on, then find the point where the output LED (yellow)
is switched off, then aim the sensor in the center between these two points.
– To further improve alignment, repeat this process while progressively reducing the sensitivity.
At the conclusion of the process, return the sensitivity to maximum.
– Optimum sensing reliability is obtained when the green LED is on (for polarized refl ex models).
– For Clear Object detection of transparent or very small targets, reduce the sensitivity dial position until the sensor
successfully detects the target material.
For E71-T/N (thru-beam source and receiver) models…
– Position the source and receiver sensor on opposite sides.
– Find the point at which the output LED (yellow) is switched on, then find the point where the output LED (yellow)
is switched off, then aim the sensor in the center between these two points.
– Optimum sensing reliability is obtained when the green LED is on.
For E71-S (diffuse refl ective) models…
– Position the sensor and turn the sensitivity dial to minimum.
– The green LED should be on, the yellow LED should be off.
– Place the target opposite the sensor.
– Turn the sensitivity dial clockwise until the yellow LED turns on (target detected state).
– Remove the target and the yellow LED should turn off.
– Turn the sensitivity dial clockwise until the yellow LED turns on (background detected state).
– Turn the sensitivity dial to an intermediate position between target detected state and background detected state.
– The green LED must be on.
For E71-F (fixed focus) models…
– The operating distance of these sensors is factory set at 11 cm ± 10 %
– To improve detection, move the target closer or further away from the sensor, or move the target perpendicular
to the sensor body (as pictured).
