ADDENDUM
This Addendum contains information that relates to the T35 Transformer Management Relay relay, version 4.0x. This
addendum lists a number of information items that appear in the instruction manual GEK-106489 (revision G1) 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/AThe version 4.0 release 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, and 8K.
The following table maps the relationship between the old CPU and CT/VT modules to the newer versions:
The new CT/VT modules (8F, 8G, 8H, 8J, and 8K) can only be used with the new CPUs (9E, 9G, 9H), and the old CT/VT
modules (8A, 8B, 8C, 8D) 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 version 4.0x is only compatible with the new CPU and CT/VT modules. Previous
versions of the firmware (3.4x and earlier) are only compatible with the older CPU and CT/VT modules.
The UCA2 specifications are not yet finalized. There will be changes to the object models described in
Appendix C: UCA/MMS Protocol.
MODULE OLD NEW DESCRIPTION
CPU 9A 9E RS485 and RS485 (Modbus RTU, DNP)
9B 9G RS485 and 10Base-F (MMS/UCA2, Modbus TCP/IP, DNP)
9C 9H RS485 and Redundant 10Base-F (MMS/UCA2, Modbus TCP/IP, DNP)
CT/VT 8A 8F Standard 4CT/4VT
8B 8G Sensitive Ground 4CT/4VT
8C 8H Standard 8CT
8D 8J Sensitive Ground 8CT/8VT
8E 8K Standard 7CT/1VT
