VALIDITY OF CHANNEL CONFIGURATION:
The current state of the communications channel identification check, and hence validity, is displayed here. If a remote
relay ID number does not match the programmed number at the local relay, the "FAIL" value will be displayed. The "n/a"
value appears if the Local relay ID is set to a default value of "0" or if the 87L element is disabled. Refer to

PFLL STATUS:
This value represents the status of the Phase & Frequency Locked Loop Filter which uses timing information from local &
remote terminals to synchronize the clocks of all terminals. If
nized and 87L protection is enabled. If it is "FAIL", the clocks of all terminals are not synchronized and 87L protection is dis-
abled. If "n/a", then PFLL is disabled.
At startup, the clocks of all terminals are not synchronized and the PFLL status displayed is FAIL. It takes
approximately 1 to 2 minutes after startup for the value displayed to change from FAIL to OK.
