GE T35 Instruction Manual page 3

Addendum
This Addendum contains information that relates to the T35 Transformer Management Relay relay, version 4.6x. This
addendum lists a number of information items that appear in the instruction manual GEK-113015 (revision K1) but are
not included in the current T35 operations.
The following functions/items are not yet available with the current version of the T35 relay:
• N/A
Version 4.0x and higher releases of the T35 relay includes new hardware (CPU and CT/VT modules).
• The new CPU modules are specified with the following order codes: 9E, 9G, and 9H.
• The new CT/VT modules are specified with the following order codes: 8F, 8G, 8H, 8J.
The following table maps the relationship between the old CPU and CT/VT modules to the newer versions:
MODULE OLD
CPU 9A
9C
9D
CT/VT 8A
8B
8C
8D
The new CT/VT modules can only be used with the new CPUs (9E, 9G, 9H), 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
error will be displayed.
HARDWARE MISMATCH
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.
