Safety Precautions

For correct use of the SE1L, take note of the following

precautions.

x SE1L is a AOPDDR (Active Optoelectronic Protective

Device responsive to Diffuse Reflection) that detects

diffused emitted light within the protection zone. The

emitted light is irradiated within the protection zone by

the rotating motor and reflects back from the objects as

diffused reflective light and is detected by the receiving

unit of the SE1L.

x Perform tests before operation to check the function and

performance of the SE1L.

x Use the SE1L within the specification range described

in the manual. To prevent degradation of detection

characteristics, make sure that maintenance is carried

out.

x To maintain the degree of protection, do not modify or

disassemble the SE1L.

x The operator must be a person qualified to operate

the SE1L. The operator must be trained and be able to

operate the SE1L correctly.

x The administrator must provide continuous training to the

operator for correct use of the SE1L.

x When using the SE1L in a safety-related system, the

administrator must be responsible for following safety

requirements, standards, rules, regulations, and laws of

each country, state, or district.

x The administrator must understand the manual and be

responsible for ensuring appropriate operating conditions

for SE1L.

∗

x To examine the object detecting performance, use a

test piece the size equivalent to the minimum detectable

object.

x Error occurs when detection capability is below 30% due

to homogenous dirt on the optical window. The operator

must keep the windows clean

x While SE1L is removed, a protective measure must

be taken to ensure safety within the protection zone.

To prevent entry into the danger zone, use protective

materials such as a safety guard or light curtain.

x Dispose the SE1L as industrial waste or in accordance

with the local regulations.

x Do not perform withstand voltage tests or insulation

resistance tests. Varistors that are used in power circuits

may be damaged.

Operating Environment

x Make sure that the operating environment is within

the range of the specifications (temperature, humidity,

vibration, light interference).

x Do not use the SE1L near a machine that may generate

strong radio waves. It may interfere with the operation of

the SE1L.

x Do not use or install the SE1L where dust, smoke, or

corrosive chemical substances exist. Using the SE1L

under these environments may lead to degradation of

detection performance.

x When the interlock function is active, make sure that the

surrounding environment, especially within the protection

zone, is safe before resetting the interlock.
