`
`all or part of the field current for the excitation of
`another exciter.
`105
`exciter platform (rotating machinery). A deck on
`which to stand while inspecting the exciter.
`63
`exciter,
`potential
`source-rectifier
`(synchronous
`machines). An exciter whose energy is derived from
`a stationary alternating current potential source and
`converted to direct current by rectifiers. Notes: (1)
`The exciter includes the power potential transformers,
`where used, and power rectifiers which may be either
`noncontrolled or controlled, including gate
`(2) It is exclusive of input control elements.
`exciter response. See: voltage response, exzciter.
`exclter response ratio, main (synchronous machines).
`The numerical value obtained when the response, in
`volts per second, is divided by the rated-load field
`voltage, which response,
`if maintained constant,
`would develop, in one half-second, the same excita-
`tion voltage-time area as attained by the actual excit-
`er. Note: The response is determined with no load on
`the exciter voltage initially equal to the the rated-load
`field voltage, and then suddenly establishing circuit
`conditions which would be used -to obtain nominal
`exciter ceiling voltage. For a rotating exciter, response
`should be determined at rated speed. This definition
`does not apply to main exciters having one or more
`series field, except a light differential series field, or to
`electronic exciters.

`exciter voltage response ratio (rotating machinery).
`See: voltage response ratio.
`exciter voltage-time response (rotating machinery).
`See: voltage-time response, synchronous-machine excl-
`tation system.
`(1) The total current applied to a coil
`exciting current.
`that links a ferromagnetic core.
`210 (2) The
`component of the primary current of a transformer
`that is sufiicient by itself to cause the counter electro-
`motive force to be induced in the primary winding.
`197
`tube provided with
`excitron. A single-anode pool
`means for maintaining a continuous cathode spot.
`190
`exclusive OR. A logic operator having the property
`that if P is a statement and Q is a statement, when P
`exclusive or Q is true if either but not both statements
`are true, false ifboth are true or both are false. Note:
`P exclusive OR Q is often represented by P 9 Q, P +
`Q. See: OR.
`255,77
`excursion (computing system). See: reference excur-
`sion.
`9,77
`execute features (1) (Class 1E power systems). The
`electrical and mechanical equipment and interconnec-
`tions that perform a function, associated directly or
`indirectly with a safety function, upon receipt of a
`signal from the sense and command features. The
`scope of the execute features extends from the sense
`and command features output to and including the
`actuated equipment-to-process coupling.
`102
`(2) (safety systems). The electrical and mechanical
`equipment and interconnections that perform a f1mc-
`tion, associated directly or indirectly with a safety
`
`function, upon receipt of a signal from the sense and
`command features. The scope of the execute features
`extends from the sense and command features output
`to and including the actuated equipment-to-process
`coupling. Note: In some instances protective actions
`may be perfonned by execute features that respond
`directly to the process conditions (for example, check
`valves, self-actuating relief valves).
`428
`execution (software). The process of carrying out an
`instruction in the instructions of a computer program
`by a computer. See: computer program; instruction.
`434
`(1) The amount of actual or
`execution time (software).
`central processor time used in executing a program.
`(2) The period of time during which a program is
`executing. See: program; run time.
`434
`execution time theory (software). A theory that uses
`cumulative execution time as the basis for estimating
`software reliability. See: execution time; software
`reliability.
`434
`executive program. See: supervisory program.
`434
`executive routine (computing systems). A routine that
`controls the execution of other routines. See: supervi-
`sory routine.
`255,77,54
`exercise (test, measurement and diagnostic equipment).
`To operate an equipment in such a manner that it
`performs all its intended functions to allow observa-
`tion, testing, measurement and diagnosis of its opera-
`tional condition.
`54
`exfoliation (corrosion). A thick layer-like growth of
`corrosion product.
`221,205
`existing installation (elevators). An installation, prior
`to the efiective date of a code:
`(1) all work of
`installation was completed, or (2)
`the plans and
`specifications were filed with the enforcing authority
`and work begun not later than three months after the
`approval of such plans and specifications. See:
`elevators.
`328
`exit (software).
`(1) Any instruction in a computer
`program, in a routine, or in a subroutine, after the
`execution of which control is no longer exercised by
`that computer program, that routine, or that subrou-
`tine. (2) The point beyond which control is no longer
`exercised by a routine. See: computer program; in-
`struction; routine; subroutine.
`434
`expandability (station control and data acquisition).
`The capability of a system to be increased in capacity
`or provided with additional functions. The measure-
`ment of expandability of equipments governed by this
`standard is the ease with which new points or func-
`tions, or both, can be added to the system, and the
`amount of downtime required to expand station
`equipments. Expandability categories are defined as
`follows: (1) spare point. Point equipment that is not
`being utilized but is frilly wired and equipped (2)
`wired point. Point for which all common equipment,
`wiring and space are provided, but no plug-in point
`hardware is provided. (3) space only point. Point for
`which cabinet space only is provided for future addi-
`tion of wiring and other necessary equipments. Ex-
`pandability limits may include but are not restricted to
