GE D60 Instruction Manual page 3

Addendum
This addendum contains information that relates to the D60 Line Distance Protection System, version 5.7x. It outlines
items that appear in the instruction manual GEK-113519C (revision U4) that are not included in the current D60 opera-
tions.
The following functions and items are not yet available with the current version of the D60 relay:
• Signal sources SRC 5 and SRC 6.
• Stub bus: The final stub bus protection is not implemented for this release. This feature can be implemented using a
phase instantaneous overcurrent function and the auxiliary contact from the line disconnect, incorporated into a Flex-
Logic™ equation.
Version 4.0x and higher releases of the D60 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 8L, 8M.
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 of mismatch between the CPU and CT/VT module, the relay
does not function and a
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.
It was discovered that f/w 5.70 to 5.72 Autoreclosure implementation deviates from the logic diagram. Latch shown in
red box below, had some deficiency and is not operating correctly. As a result, it is not blocking AND gate connected to
the AR 3-P/1 RIP path, resulting in the breaker close operation with a AR 3-P DEAD TIME 1 timer, when there are two
simultaneous initiation via AR 3-P INIT and via AR 3-P TD INIT paths.
In case of a single initiation via either AR 3-P INIT or via AR 3-P TD INIT, Autoreclosure will execute sequence correctly,
using either AR 3-P DEAD TIME 1 or AR 3-P DEAD TIME 2 timers correspondingly.
If, however, there are two initiations simultaneously or consequently, Autoreclosure in 5.70-5.72 f/w will issue a close
command via AR 3-P Dead Time 1 timer always, ignoring second initiation.
