The following events are logged for the Synch Check relay:
• Synch Check Control Enabled 1…6 – Synch check relay 1…6 has been enabled
• Synch Check Control Disabled 1…6 – Synch check relay 1…6 has been disabled
• Synch Check 1…6 Sources Not Synchronized – Messengers that are providing voltage
information for synch check relay are not synchronized, so Entellisys is unable to check for
synchronization between voltage sources.
• Synch Check 1…6 Sources Not Compatible – Voltage sources for synch check relay 1…6 are
not compatible; i.e. they have different PT configurations or ratings
• Synch Check 1…6 Dead Source Operate – Dead source criteria for synch check relay 1…6
have been met
• Synch Check 1…6 Dead Source Drop Out – Dead source criteria for synch check relay 1…6
have been met
• Synch Check 1…6 V1 Above Minimum – Voltage source 1 for synch check relay 1…6 is above
the live source threshold
• Synch Check 1…6 V1 Below Maximum – Voltage source 1 for synch check relay 1…6 is below
the dead source threshold
• Synch Check 1…6 V2 Above Minimum – Voltage source 2 for synch check relay 1…6 is above
the live source threshold
• Synch Check 1…6 V2 Below Maximum – Voltage source 2 for synch check relay 1…6 is below
the dead source threshold
