PROHIBITION
Pages
* Don't decompose this device. It may cause any troubles by short-circuit. Moreover it may cause
malfunction of device out of warranty.
* Keep this device out of soaking in water, oil or scales. Light-receiving amount is reduced and it
may cause mis-detection. Also, inner circuit corrodes and it may cause any troubles.
* Don't install or keep this device at the place where over rated heat, vibration or shock. It may
cause any troubles or malfunction.
* Avoid to use under solvent vapor and corrosive gas.

ENFORCEMENT
Pages
* Clean up lens surface of both light-projecting and receiving part with soft cloth periodically. When
light-projecting and receiving part are dirty, it can't keep specific detection area.
* Don't make a wiring with power line such as driven motor or break.
* Earth frame ground terminal to the body when switching regulator is used as power source.
* Connect unused input cable to input common +(Red) or open it. Connect unused output cable to
output common –(Gray) or open it.
* Be sure to adjust, checking detection area data and real time data with application software for PC
setting when PC model. Make sure to check some operations after setting.
* Make a optical axis adjustment and check some operations before use.

Introduction
CAUTION
* Be sure to read the instruction manual carefully before servicing this device. Be sure to reach the instruction
manual to final user and be sure to keep the instruction manual by final user.
General
(1) Operating principle
Operating principle is that semicircular field is scanned by LED(lambda = 880nm) and the coordinates is
calculated by measuring distance to object and its step angle and it detects obstacle in setting area.
(2)Detecting area setting
Shape of detecting and setting value can be changed by PC(RS-232C). Detecting distance with 3 steps output
for each detecting area can be set.
