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 precautions 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.
WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or
!
serious injury.
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 “PC” means Programmable Controller and is not used as an abbreviation for anything else.
