FOREWORD: This directive defines " functional" or " legend" and

" identification" label requirements. Identification labeling provides an alpha-numeric identifier or in some cases simply a number by which a device, or component is traceable to various documents. The functional or legend label provides information to the operator as to the system function or parameter

, controlled by a given device. While the alpha-numeric informition displayed by a function label is usually of primary interest, additional information may be provided by label color, size. font, and location. For example, label color may indicate a particular type of function, a certain operational status, danger, or useage in a demarcation scheme. Size may indicate hierar:hical value or only that differences in selection criteria existed.

Two general requirements must be met in providing labels. The first is that the label provides the required information in a clear and concise presentation, readable from the normal operating position. The second is that the label is designed and located consistent with established meanings of color, size, and location. As an aid in meeting these requirements for the majority of users, certain human factors principles and anthropometric considerations are included as an integral part of this directive. Acronyms and abbreviations selected for labeling use shall conform to Design Directive 00-AAS-1.

SELECTION CONSIDERATIONS I. GENERAL A. MINIMUM LABELING REQUIREMENTS:

1. Each panel board or major division of a control board shall be labeled with either an equipment number or a functional title. (See Figure 2) 0511060304 851029 PDR F ADOCK 05000267 PDR F ORM 372 22 - 3643

(

PUBLIC SERVICE COMPANY OF COLORADO CD-LAB-1 FORT ST. VR AIN NUCLEAR GENER ATING STATION Issue g Page 2 of 12

2. Each subsection, bay, bin, drawer, or demarcated area of a panel or control board shall be labeled with a location number or a functional title. (See Figure 2)
3. Each module of a bin or drawer shall be labeled with an instrument number, functional description, or other identifier. (See Figure 2)
4. Each indication, control, switch, or other instrument shall be labeled with an instrument number and a functional d'scription, except:
a. Labels bearing instrument numbers need not be provided for indicators, controls, and/or switches which are an integral part of an assembly. (example:

recorders)

b. Labels bearing instrument numbers and functional information need not be provided for indicating lights where such indicating lights are grouped with the associated handswitch in accordance l with Figure 3.
5. Instrument numbers and functional information may be combined on a single label where surface area is available to accept the increased label size.

B. ADDITIONAL LABELING

1. System designation labels shall be provided for groups of controls that are functionally arranged by system or subsystem.
2. Labels shall be provided to show special information where such information is required to properly operate a system or control.
3. Instructing charts, or other permanentally affixed information shall be provided where an operator is required to convert data, indications, or scale values.

F O R M 3 72 2.2 - 36C3

PUBLIC SERVICE COMPANY OF COLORADO gg_,_3g 1 FORT ST. VRAIN NUCLEAR GENERATING STATION Issue B Page 3 of 12 II. LABEL LOCATIONS A. CONTROL BOARDS Labels shall be located on the top of each board, above the top row or grouping of instruments (excluding alarm panels) and centered on the control board. (See Figure 2)

B. CONTROL BOARD SUBDIVISIONS Subpanel, bays, and system subdivision labels shall be located at the top center of each subdivision.

(See Figure 2)

C. BINS AND DRAWERS Bins and drawer labels shall be centered immediately above or to the left of the bin or drawer. (See Figure 2)

D. FUNCTION AND INSTRUMENT LABELS

1. Function labels shall be located so as to be visible by the user during instrument viewing or manipulation.

For new control board installations functional labels for indicators shall be located below the indicators and above the controls. These locations offer some assurance that the label will not be obscured by the operator's hand or arm during manipulation of a control.

For existing board installations new function label locations shall conform to the established convention for that board, l provided such location does not compromise the requirement for the label being visible during operation.

2. Instrument tag locations shall be selected for consistency with convention and need not be selected to assure visibility during operation.
3. Function and instrument labels shall be located so as not to obscure any part of an instrument scale, control, or informational source intended for operator use.

c PUBLIC SERVICE COMPANY OF COLORADO DD-LAB-1 FORT ST. VRAIN NUCLEAR GENERATING STATION Issue g Page 4 of 12 III. DIMENSIONAL CONSIDERATIONS The dimensional factors of labeling take on greater significance because of the variation in operator heights.

Distance from the operators eyes to the panel is, therefore, variable, and must be taken into account during lacel design. As this distance ircreases, the perceived dimensions of characters, symbols, spacing, etc. decreases proportionately because of a reduction of the " visual angle." This is the vertical angle subtented at the eye by a viewed object, symbol, or character, usually expressed in minutes of arc. For visual angles less than 600 minutes, this relationship is shown by:

a = (57.3) (60) L 0

where "L" is measured prependicular to the line of sight.

Under optimum conditions (illumination, contrast, etc.)

the human eye can identify characters of the alphabet at visual angles of 5 minutes of arc (defining 20:20 vision).

Since presentations on a panel or control board in an operational environment do not approach the optimum conditions of vision testing, this lower level must be increased. The minimum acceptable angle under these less then optimum conditions has been established as approximately 14 minutes. This value equates to the following formula from which the dimensional requirements of this directive are derived.

Minimum Character Height = Viewing Distance x .004 Where: character orientation is perpendicular to the observer's line of sight. For tilted panels or surfaces the character height is increased to compensate for tbo parallactic effect. (See Figure 1)

A. LABEL SIZE

1. CONTROL BOARDS Control boards, control board subdivisions, bays, bins, and system subdivision labels shall be in accordance with Figure 4.

I Styles 1, 2, 3, and 4 are sized for a single I line of text. Styles 1x, 2x, 3x and 4x are I sized for two (2) lines of text.

F OR M 3 72 3643

2. INSTRUMENT AND CONTROLS Instrument and control labels shall be in accordance with Figure 4.

B. CHARACTER SIZE

1. CONTROL BOARD Labels identifing control boards shall have characters .87" .05" in height and .52" :

.05" in width.

2. CONTROL BOARD SUBDIVISION OR BAY Labels identifing control board subdivisions or bays shall have characters .-75" .05" in height and .50" .05" in width.
3. BIN AND DRAWER Labels identifing bins or drawers shall have characters .62" .05" in height and .37"

.05" in width.

4. SYSTEM OR DEMARCATED AREA Labels identifing system subdivisions within a control subdivision shall have characters .62"

.05" in height and .37" .05" in width.

Labels identifing loop or redundant subsystems, within a b stem subdivision shall have characters .50" .05" in height and .30

5. INSTRUMENTS Instrument numbers and functions label j character size shall conform to Figure 1 & 5.

l Two (2) columns are shown on Figure 1 for character heights on vertical panels. One column lists the minimum acceptable heights for those existing labels used by the control room operators in the direct performance of plant operations. The second column lists the preferred character heights for operator used labels and considers the limitations placed on mounting heights imposed by Design Directive l DD-CBL-1/ Control Board Layout. Labels on I-l 9310 not used by the control room operators need not meet the requirements of this directive.

IV. LABEL COLORS A. Specific colors serve to identify certain plant systems and functions. Existing label color coding schemes shall be applied as applicable.

Any additional label color coding schemes shall be selected to assure the following:

1. Selected color shall be different for each unique function
2. Selected color shall offer a suitable contrast with the surface upon which the label is to be located.

B. COLOR ASSIGNMENT

1. All instrument and function labels, unless otherwise specified, shall be black with white letters.
2. All plant protective system labeling shall be red with white letters.
3. Power bus designations placed on handswitches for operator information shall be yellow with black letters.

V. CHARACTER STYLE All characters shall be of a gothic style conforming to I the dimensions defined by Figure 5.

VI. LABEL MATERIAL Nameplate material shall be one eigth (1/8) inch thick, l' three (3) ply lamicoid (or equal) plate. Surface and Core material shall be selected for conformance to the color assignment convention.

VII. ENGRAVING Engrave Lamicoid (or equal) 3 ply plate through surface ply, into center ply using a rounded or square end cutter.

("V" shaped grooves are not acceptable)

VIII. TEMPORARY LABELS Temporary labels may be used in ac:ordance with the following:

A. Where a new installation is being made under an approved change notice and the required permanent labels are unavailable, the change notice as built package must remain open until the permanent labels are installed.

B. Where additional information is required to safely operate the plant, provided such temporary label is recorded and approved by the Temporary Change Request procedure and a Design Change Action Request is initiated.
