A-4 Firmware Versions Date Code 20001006
SEL-351 Instruction Manual
Firmware Part/Revision No. Description of Firmware
These firmware differ from previous versions as
follows:
− SELOGIC Control Equation
®
torque control settings
for overcurrent elements can no longer be set directly
to logical 0.
− SELOGIC Control Equation drive-to-lockout settings
79DTL has a 60-cycle dropout time, as explained in
Section 6: Close and Reclose Logic.
− Corrected DNP lockup problem.
− Corrected part number entry problem for firmware
upgrades.
− Corrected voltage labeling problem for delta-
connected voltage models.
− SELOGIC Control Equations settings limits displayed
when settings saved (see Table G.2 in Appendix G:
Setting SELOGIC Control Equations).
− Made the following SELOGIC Control Equations
factory default settings changes (now that 52A is
available as a Relay Word bit):
• 79RIS = 52A + 79CY
• DP2 = 52A
• BSYNCH = 52A
