Notice:
OMRON products are manufactured for use according to proper procedures
by a qualified operator and only for the purposes described in this manual.
The following conventions are used to indicate and classify precautions in this
manual. Always heed the information provided with them. Failure to heed pre-
cautions can result in injury to people or damage to property.
!DANGER Indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury. Additionally, there may be severe property damage.
!WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury. Additionally, there may be severe property damage.
!Caution Indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury, or property damage.
OMRON Product References
All OMRON products are capitalized in this manual. The word “Unit” is also
capitalized when it refers to an OMRON product, regardless of whether or not
it appears in the proper name of the product.
The abbreviation “Ch,” which appears in some displays and on some OMRON
products, often means “word” and is abbreviated “Wd” in documentation in
this sense.
The abbreviation “PLC” means Programmable Controller. “PC” is used, how-
ever, in some Programming Device displays to mean Programmable Control-
ler.
Visual Aids
The following headings appear in the left column of the manual to help you
locate different types of information.
Note Indicates information of particular interest for efficient and convenient opera-
tion of the product.
