Notice:OMRON products are manufactured for use according to proper proceduresby a qualified operator and only for the purposes described in this manual.The following conventions are used to indicate and classify precautions in thismanual.Always heed the information provided with them.Failure to heed pre-cautions can result in injury to people or damage to property.DANGERIndicates an imminently hazardous situation which,if not avoided,will result in death orserious injury.Additionally,there may be severe property damage.WARNINGIndicates a potentially hazardous situation which,if not avoided,could result in death orserious injury.Additionally,there may be severe property damage.CautionIndicates a potentially hazardous situation which,if not avoided,may result in minor ormoderate injury,or property damage.OMRON Product ReferencesAll OMRON products are capitalized in this manual.The word "Unit"is alsocapitalized when it refers to an OMRON product,regardless of whether or notit appears in the proper name of the product.The abbreviation"Ch,"which appears in some displays and on some OMRONproducts,often means "word"and is abbreviated "Wd"in documentation inthis sense.The abbreviation "PLC"means Programmable Controller."PC"is used,how-ever,in some Programming Device displays to mean Programmable Control-ler.Visual AidsThe following headings appear in the left column of the manual to help youlocate different types of information.Note Indicates information of particular interest for efficient and convenient opera-tion of the product.1,2,3...1.Indicates lists of one
