2.3.3 Cable administration charts
Cable administration charts document wire terminations within system enclosures. Tag
names should be consistent and represent physical locations or machines. For instance,
instead of naming a sensor 23001, use a name like FAN1OV (fan number 1 outboard
vertical) to make system maintenance and troubleshooting easier. After tags are assigned,
document them in cable administration charts. All enclosures for the system need cable
administration charts.
There are two types of cable administration charts for the online system: junction box and
AMS 6500 enclosure.
Junction box cable administration chart
The online system junction boxes provide a junction between the instrumentation cable
and the multi-pair bundled cable that is pulled back to the AMS 6500. The cable
administration chart for a junction box documents the channel number, wire tag, sensor
type, and sensor location if the wire tag does not contain location information. Figure 2-3
shows a typical installation.
