UR Family Firmware 5.84 - Release Notes
23
G
Corrected firmware to prevent incorrect deactivation of the “ANY MAJOR ERROR” FlexLogic operand
when a minor self-test error is cleared
Products: All
Impacted firmware: All to 6.05
Corrected firmware: 5.84, 6.06, 7.xx
Workaround: None
Description: When a minor self-test clears, it also deactivates the “ANY MAJOR ERROR” FlexLogic operand.
For example, a relay in “Not Programmed” state asserts the “ANY MAJOR ERROR” FlexLogic operand.
Clearing a minor self-test de-asserts this operand, even though the relay is still not programmed. The new
releases fix the issue.
GE tracking number: 606-5
R
Changes to the DSP setting buffer prevents nuisance alarms
Products: All
Impacted firmware: 5.70 to 6.04
Corrected firmware: 5.84, 6.05
Workaround: None
Description: The internal DSP register used to calculate the checksum of the setting buffer is corrected to
0 during initialization. Some previous versions had an incorrect initial value, thus the configuration of
sources (for example, enabling the source) incorrectly triggers Module Failure 07.
GE tracking number: 605-11
E
Improved Restricted Ground Fault (RGF) element
Products: All with Restricted Ground Fault element (F60, G30, G60, L90, T35, T60)
Impacted firmware: All to 6.06, 7.00 to 7.27, 8.00 to 8.02
Corrected firmware: 5.84, 6.07, 7.28, 8.03
Workaround: None
Description: The new releases improve the Restricted Ground Fault element by adding supervision of the
ground current to prevent misoperation due to unbalanced phase currents during normal load conditions.
GE tracking number: 803-6
M Corrected phase-to-phase voltage metering for WYE connection
Products: All except C30
Impacted firmware: All to 6.06, 7.00 to 7.27, 7.30 to 7.82
Corrected firmware: 5.84, 6.07, 7.28, 7.90
Workaround: None
Description: Phase-to-phase voltage metering is incorrect when the injected phase-to-ground voltages
are greater than 160 V and the Phase VT secondary setting is less than 140 V. The new releases correct
the issue.
