ADDENDUM
This Addendum contains information that relates to the L60 Line Phase Comparison Relay relay, version 4.9x. This
addendum lists a number of information items that appear in the instruction manual GEK-113209A (revision M2) but are
not included in the current L60 operations.
The following functions/items are not yet available with the current version of the L60 relay:
•N/A
Version 4.0x and higher releases of the L60 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, and 9R.
• The new CT/VT modules are specified with the following order codes: 8F, 8H, 8P.
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 the old CT/
VT modules can only be used with the old CPU modules (9A, 9C, 9D). To prevent any hardware mismatches, 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.
