SEL-787-R110-V0-Z002001-D20140714
➤ For relays configured with delta-connected CTs, resolved an issue in
R107–R109 firmware versions where power calculations in the MET
report were incorrectly scaled down by . Protection elements were
not affected by this issue.
➤ Revised the firmware for Trip Logic such that RSTTRGT is processed
on the rising edge.
➤ Modified the firmware to make the MATHERR Relay Word bit
visible.
➤ Resolved an issue where the front panel showed a blank page after
resetting a TRIP message.
➤ Added a feature for Event Data registers in Modbus to always show
the latest event data unless a specific event is selected by the event
selection register.
➤ For relays configured with delta-connected CTs, resolved an issue in
R107–R109 firmware versions where current harmonic calculations in
the MET H report were incorrectly scaled down by . Protection
elements were not affected by this issue.
➤ For relays configured with delta-connected CTs, resolved an issue
where Through Fault (TFE) accumulated current calculations in the
TFE report were incorrectly scaled up by .
➤ Addressed an issue with setting the IP address of more than on DNP
session to 0.0.0.0. They relay now allows only on DNP session at IP
address 0.0.0.0.
➤ Resolved an initialization issue with the V/Hz (24) element after
changing DELTA_Y and 24WDG settings. The element was always
initialized and functioned correctly if the settings were changed from
the default (DELTA_Y := DELTA and 24WDG := WYE) to any other
setting combination. The element was not initialized correctly if the
user started with settings DELTA_Y := WYE and 24WDG := WYE
and changed to other combinations. The element was initialized
correctly for any setting combination if the relay was restarted after a
settings change.
➤ Resolved an issue with the V/Hz element for the settings combination
DELTA_Y:= DELTA and SINGLEV := Y. With this settings
combination, the V/Hz did not function and the MET report showed
zero for V/Hz.
Firmware version R110 is for upgrading relays with R100–R109.

SEL-787-R109-V0-Z002001-D20130426
➤ Forced RTS to high and ignored CTS when PREDLY setting is OFF to
power certain fiber-optic transceivers.
➤ Corrected an Ethernet Failover Switching issue for dual Ethernet
models.
➤ Corrected an issue where old packets were returned on new
connections when polling Modbus at high speed.
➤ Corrected an issue with the initial Gratuitous ARP request not being
sent for as long as five minutes after startup.
➤ Corrected an issue of missing SER records upon warm start.
➤ Corrected an issue that caused port settings to be rejected when relay
settings were downloaded using
ACSELERATOR QuickSet
®
SEL-5030
Software.
ACSELERATOR QuickSet reported with a message that
settings files were not received.
Firmware version R109 is for upgrading relays with R100–R108.
