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.
