Electric Eye Sensor Adjustment
To adjust the sensor, first remove the clear plastic cover from the end of the sensor. There are
two adjusting screws under the cover. One is labeled “GAIN” and is used to set the sensitivity of the
sensor. The other screw is labeled “DO & LO” and should
always be fully clockwise.
With the end of the sensor pointing at the center of the
reflective tape, turn the “GAIN” screw counter-clockwise until
the red LED indicator is off. Then turn the “GAIN” screw
clockwise until the LED indicator comes on. Then turn the
“GAIN” screw one full turn clockwise. The LED indicator
should be blinking slowly. Cover the eye so that the sensor
cannot see the reflective tape and the LED should go off.
Reflective Tape Maintenance
Use a soft cloth for cleaning.
Do not use chemicals or abrasives to clean it.
Avoid any contact with oils and liquids.
Do not touch the tape with bare fingers.
If tape is dirty or opaque, the eye may not function correctly.
