Burst Firing (BF) 

The Burst Firing is similar to the Single Cycle, but consecutive cycles ON are selectable between 2 and 

255, with input signal equal at 50%. 

Burst Firing is a method zero crossing that it reduces the electromagnetic interferences because the 

thyristor switches at zero voltage crossing.

Soft Start with Burst Firing (S+BF) 

This is an additional function to the Burst Firing. The unit start in phase angle mode with a ramp starting 
from zero up to the full tension in the cycles number set in the parameter P084 



When the ramp is over, the thyristor unit will stay in conduction at full voltage up to the end of cycles of 

burst. The S+BF firing is used to control small inductive loads to avoid inrush surge current and to 

reduce the electromagnetic interferences.
