Firing setting
The BF firing performed in Digital mode in CD Automation Thyristor unit give a lot of advantages because
switches Thyristor at zero voltage crossing (ZC) without EMC interferences. Analog input is necessary for
BF and can be decided how many complete Cycle we want at 50% of power demand.
This value can be 4, 8 or 16 complete Cycles.

The input type is already configured in line with customer requirements that are defined in the complete
product code. However, if you wish to change the input type (ex. from 0÷10V to 4÷20mA) set the
jumpers as below represented and then do the “Input calibration procedure”.
