We’re seeing some strange behavior on the REF615 relays we have installed at site. Our site is in South Australia, which means we have daylight savings enabled to show the correct local time. We have a GPS clock providing SNTP V4 time synchronization over the network, and the following settings configured in the REF615 relays:
Local time offset = 570 DST in use = True DST on time = 2AM, First Sunday in October DST off time = 3AM, First Sunday in April DST offset = 60min Sync source = SNTP
The issue we are seeing is that when the local time is in the daylight savings period, the REF615 relays are still synchronizing to UTC+9.5, no DST offset. I’ve forced the GPS clock to multiple dates which should have shown as daylight savings time, but it’s always an hour out. The relay is definitely receiving the SNTP packets and updating times, I’ve also tried setting my laptop as an NTP server but with no luck.
If anyone can help, it would be appreciated. The REF615 relays are SW version 5.1.10.
Did you enable time synchronisation. Because even if you put sync source as SNTP and did not enable the time sync & put the IP address of SNTP server, time synchronization will not work. try with default setting fro DAY NIGHT settings & OFFSET, as they are required only when you dont have any time master. When GPS is being used, it will take care of all the day time savings & any offset.
In short, time sync should be enable, and IP address of SNTP server should be put inside the relay
