Component Labeling Convention
This document describes an NIR ID labeling convention that can be used to identify NIR
instrument components on drawings, documents, software labels and comments, and
physical labels. The NIR IDs uniquely identify a component location on the instrument or
in the maintenance kit. An ID can be occupied by any one of several serial numbered
components of the appropriate type for that location. Serial numbers uniquely identify an
instance of a component. If a component fails it can be replaced with another serial
numbered component of the same type. This new serial numbered component assumes
the ID for its new location in the system.
The acronyms listed for each field are enumerated so programmable components can
be digitally labeled using this convention. Field values of zero are reserved for block
identification of all devices identified by the next higher field.

ID:
001-999 - Multiple devices in the instrument that share the same values for all the fields
above are enumerated to distinguish them.
Example:
NIR-PD-FLI-PRX-003
-might identify the home position index reed switch on the filter inserter mechanism.
Serial Numbers:
The labeling convention outlined above identifies a component location in the
instrument. Active components should also be serial numbered by programming or
labeling to distinguish instances of components that could be installed in the same
location in the instrument. In other words, the serial number distinguishes original,
replacement, and spare components. This information is used for maintenance logs.
Cable Labeling
The cables for the Control System cables Power Distribution System are labeled using
two different conventions. The control system cables use the same convention used for
all other components just described.
Cables will have two labels on each end. The labels nearest the connectors on each
end of a cable will be different and identify where that end of the cable gets connected.
The labels away from the connectors on each end of the cable will be the same. They
will identify the cable as a unique component in the system. Short cables that don’t
extend into more than one enclosure/major assembly only require a single component
ID label at its center.
Control System Cables
The label nearest the connector identifies the component or cable that is its mate. It will
have two lines of text. If the connector mates with a cable it will have the mating cables
ID. If the connector mates to a component, the first line will identify the enclosure/major
assembly where the cable end is connected, the mechanism associated with the cable,
and the function of the device connected. The second line of the label will identify the
device ID and a number that identifies a connector on that device.
The labels toward the center of the cable identify the cable itself so the labels on each
end have the same ID. If it is a short cable, it may have a single label in the middle of its
length. The label will have two lines of text. The first line will say “NIR” so the cable is
not mistaken for a general-purpose cable and misallocated. The second line will have
the remainder of the string that adheres to the labeling convention described above to
identifying the cable just any other system component is identified.
Here is an example of some labels for a cable that connects a motor drive in the control
enclosure to the a motor on the filter inserter in the pre-dewar:
NIR
NIR
NIR
NIR-PD-FLI-MOT
CE-FLI-DRV-001
PD-FLI-CBL-001
PD-FLI-CBL-001
001-J1
Power Distribution System Cables
The label nearest the connector will follow the same conventions as the control system
cables.
The labels toward the center of the cable will have two lines of text. The first line will say
“NIR” so the cable is not mistaken for a general-purpose cable and misallocated. The
second line will identify the fields listed in the table below.
