ADDENDUM
This addendum contains information that relates to the N60 Network Stability and Synchrophasor Measurement Sys-
tem, version 5.5x. This addendum lists a number of information items that appear in the instruction manual GEK-
113419B (revision
S3
) but are not included in the current N60 operations.
The following functions and items are not yet available with the current version of the N60 relay:
• N/A.
Version 4.0x and higher releases of the N60 relay includes new hardware (CPU and CT/VT modules).
• The new CPU modules are specified with the following order codes: 9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P, 9R, and 9S.
• The new CT/VT modules are specified with the following order codes: 8F, 8G, 8H, 8J 8L, 8M, 8N, 8R.
The following table maps the relationship between the old CPU and CT/VT modules to the newer versions:
The new CT/VT modules can only be used with the new CPUs (9E, 9G, 9H, 9J, 9K, 9L, 9M, 9N, 9P, 9R, and 9S), and
the old CT/VT modules can only be used with the old CPU modules (9A, 9C, 9D). To prevent any hardware mis-
matches, the new CPU and CT/VT modules have blue labels and a warning sticker stating
“Attn.: Ensure CPU and
DSP module label colors are the same!”
. In the event that there is a mismatch between the CPU and CT/VT module,
the relay will not function and a
DSP ERROR
or
HARDWARE MISMATCH
error will be displayed.
All other input/output modules are compatible with the new hardware.
With respect to the firmware, firmware versions 4.0x and higher are only compatible with the new CPU and CT/VT mod-
ules. Previous versions of the firmware (3.4x and earlier) are only compatible with the older CPU and CT/VT modules.
