Display in case of break of secondary side of a transformer
When the signal level goes below the determination set value in case of a break on the secondary side of the transformer, the
displayed value flashes. (Parameters of input signal monitor 1 and phase angle ratio monitor flash)
When the instrument is automatically released from the break (momentary power failure), the display stops flashing and remains
lit.
Output limiter setting in case of a break on the secondary side of the transformer
This is a function to limit the phase angle between 20.0 % and 50.0 % when the signal goes below the determination set value
in case of a break on the secondary side of the transformer.
Soft-start function in case of break on the secondary side of the transformer
This is a soft-start function which is activated when the instrument is automatically released from the break (momentary power
failure) of the secondary side of the transformer.
This function suppresses the inrush current at the time of automatic release from the break (momentary power failure).
While the soft-start function of the soft-start time (U) is working, if break (momentary power failure) of secondary side of
a transformer occurs, protection function for control of primary side of a transformer starts working to suppress the
output.
When released from the break (momentary power failure), the instrument changes the output according to the soft-start
time in case of break on the secondary side of the transformer (u).
After elapse of the soft-start time in case of break on the secondary side of the transformer (u), the soft-start time (U)
takes over, and output is changed in the remaining time of the soft-start time (U).
