A
HRGF Location - Breaker Trip Logged when location function 1 trips
HRGF Location - Discrete Output
Unavail Function 1-4 Logged when one of the following conditions
takes place
- no discrete I/O card in the system, wrongly
configured or hardware failure
- no discrete outputs are configured
- none of the configured outputs is set to be
operated by HRGF Location function 1
HRGF Location - Detection Not
Optioned Function 1-4 Logged when breaker that location function
1 is associated with does not have HRGF
optioned.
FlexLogic Ended Reduced
Let-Thru Mode-Multipoint Logged when FlexLogic disables multipoint
RELT
HRGF Location Incomplete
Missing Data Function 1-4 This event is logged when some messengers
are either decommissioned or
non-communicating or not-synched.
Relays – Synch Check
Synch Check Control Enabled
1…12 Synch check relay 1…12 has been enabled
Synch Check Control Disabled
1…12 Synch check relay 1…12 has been disabled
Synch Check 1…12 Sources Not
Synchronized Messengers that are providing voltage
information for synch check relay are not
synchronized, so the CPU is unable to check
for synchronization between voltage sources. This should only happen on start-up, or when
a Messenger is connected to the system (or
rebooted). If it happens repeatedly during
normal operation, contact GE Post Sales
Service (see
How to contact us on page 2 ).
Synch Check 1…12 Sources Not
Compatible Voltage sources for synch check relay 1…12
are not compatible; i.e., they have different PT
configurations or ratings
•
Verify that the Source Voltages for the
synch check relay are correct.
•
Verify that the source voltages have the
correct PT configurations.
Synch Check 1…12 Dead Source
Operate Dead source criteria for synch check relay
1…12 have been met
Synch Check 1…12 Dead Source
Drop Out Dead source criteria for synch check relay
1…12 have been met
Synch Check 1…12 V1 Above
Minimum Voltage source 1 for synch check relay 1…12
is above the live source threshold
Synch Check 1…12 V1 Below
Maximum Voltage source 1 for synch check relay 1…12
is below the dead source threshold
Synch Check 1…12 V2 Above
Minimum Voltage source 2 for synch check relay 1…12
is above the live source threshold
