HRGF Location - Detection Not
Optioned Function 1-4
Logged when breaker that location function 1 is
associated with does not have HRGF optioned.
HRGF Location Incomplete

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
