Firmware 5.84
Bus Differential Systems – B30, B90
R
Oscillography functionality has been changed to accurately show current values of the 7th analog
channel of 8K type DSP modules
Products: B90
Impacted firmware: All to 5.83, 5.85 to 6.02, 6.04 to 7.21 and 7.23 to 2.28
Corrected firmware: 5.84, 6.03, 7.22, 7.30 and above
Workaround: None
Description: Analog values shown on an oscillography record are a scaled representation of captures
values. B90 devices with previous firmware versions showed that scale factors were incorrectly applied to
the 7th analog channel of any 8K type Digital Signal processor (DSP) module installed in the relay. This
firmware version ensures that accurate values are shown and scale factors are applied correctly to all
analog channels regardless the type of DSP module installed. Performance of protection elements is not
compromised by this issue. For details on the B90 oscillography, see the B90 instruction manual.

P
Improved accuracy of bus differential pickup in the region between Low and High breakpoints
Products: B30, B90
Impacted firmware: All to 6.06, 7.00 to 7.28, 7.30 to 7.82
Corrected firmware: 5.84, 6.07, 7.28, 7.90
Workaround: None
Description: The accuracy of bus differential pickup in the region between Low and High breakpoints is
improved.
GE tracking number: 790-46
B
Corrected firmware to prevent unexpected restart in B30, B90
Products: B30, B90
Impacted firmware: All to 6.05, 7.00 to 7.26
Corrected firmware: 5.84, 6.06, 7.27, 7.30 and up
Workaround: None
Description: A B30 or B90 relay can experience an unexpected restart when zone 2 or higher LEDs are
turned on. In the new releases, this issue is resolved.

Common Platform Functions
E
Improved security by adding rule to prevent entering the “<” character in text-based
Products: All
Impacted firmware: All to 6.06, 7.00 to 7.27, 7.30 to 8.03
Corrected firmware: 5.84, 6.07, 7.28, 8.10
Workaround: Avoid using the “<” character in text-based settings
Description: In the new releases, for improved security, the less-than sign “<” is invalid for text-based
settings, such as IED names and sources names.
