Phase Synchronisation Error

[Anonymous user]

Hello Sir,

We have 40KVA Smart Online UPS and we give inout source from 250KV DG generator at Daytime and from 63KV DG Generator at Night time.
We dont have Grip Power Supply.
At day time UPS is working normally, some times it is showing phase synchrozitation error and sutomatically is disappears after one or two minutes.

At night when we give Input Supply from 63KV DG supply , UPS showing Site Wiring Fault and Stops charging batery, resulting discharging of Battery and UPS Shutdowns.
Hoe to set ignore mode for all phase errors in UPS.
