Time Synchronization
Fault Analysis
If there is no SNTP signal for more than 120 sec, the SNTP status changes from “active” to “inactive” and an entry
in the Event Recorder will be created.
The SNTP functionality can be checked in the menu [Operation/Status Display/TimeSync/Sntp]:
If the SNTP status is not indicated as being “active”, please proceed as follows:
Check if the wiring is correct (Ethernet-cable connected).
Check if a valid IP address is set in the device (Device Para/TCP/IP).
Check if the IP address of the SNTP server is set in the device (Device Para/ Time/ TimeSync/ SNTP).
Check if SNTP is used for time synchronization (Device Para/ Time/ TimeSync/ TimeSync).
Check if the Ethernet connection is active (Device Para/TCP/IP/Link = Up?).
Check if both the SNTP server and the protection device answer to a Ping.
Check if the SNTP server is up and working.
