This Slandard specihes graphical symbols tor mea- surement and control functions in diagrams, with the same symbols in simple applications possibly represent- ing instead components or devices implementing such functions. For graphical symbols for measurement and control components and devices, see ASME Y14.40.5. For the fundamentai rules of creation and application of graphical symbols in diagrams, see ASME Y14.40.0. For an overview of the ASME Y14 40 scrics, informa- tion on the creation and use of registration numbers for identifying graphical symbols used in diagrams, rules for the presentation and application of these symbols, and examples of their use and application, see ASME Y14.40.1. 2 REFERENCES The following references contain provisions which, through reference in this text, constitute provisions of this Standard.

NOTE: Control may include monitoring and safeguarding in addi tion to the control action itself. 3.2 operalion: trartsfer of mechanical parts. EXAMPLE: The closing member of a shut off valve or the contacts of an electromechanical switching device. NOTES. (1) The transfer direction may be defined as an opening operation, closing operation, ON-operation. OFF- operation. etc. (2) The Ler has a specilic meaning in cunjunction with eletric measuring relays. An over/ under-relay is operating when its charactenstic quantity Treaches the set value by increasing/ decreasing in value (IEC 60050 48). 3.3 murnua! control: contro! of an operation by human inter vention.ASME Y14.40.6 pdf download.
