5.2 Max Volt Delta
Maximum voltage difference between
the two sources to be synchronised
10V 5‐50V
5.3 Max Freq Delta
Maximum frequency difference

synchronised
1Hz 0‐10Hz
5.4 Max phi Delta
Maximum phase angle difference
between the two sources to be
synchronised
2' 2‐20'
5.5 Max sync time
Maximum waiting time for
synchronization conditions,After this
time,an alarm is performed.
6S 0‐1000S
5.6 Sync hold time
Instantaneous parallel time in closed
transition
0.30S 0.01‐1.00S
5.7 Sync over time Enforce break time in closed transition 0.00S 0.00‐600.00S
5.1 Turn on closed transition function in manual mode; you need to set the OFF POSITION to "two‐position" to perform closed transition. When the
power source mode set as mains to mains,if S1&S2 power parameter difference meet 5.2 Max Volt Delta 5.3 Max Freq Delta5.4 Max phi Delta in counting
time, then it will implement transfer synchronized, The Instantaneous parallel time is based on 5.6 "sync hold time". During operation If the waiting
time over 5.5 max sync time it will perform alarm: closed transition overtime,if power source type set as” mains‐genset” the controller start the generator
output first, and S1&S2 will transfer synchronized when meet the closed transitions conditions, if the waiting time over max sync time it will perform
alarm.
5.2 Turn on closed transition function in auto mode: need to operate under return to “main power”, if the waiting time over max sync time it will remind
closed transition overtime.
