CONFIGURATION OF THE DRIVER BOARD
The 460 series thyristor units are fitted with a strip of miniature switches and two jumpers used to select :
• the input type
• the desired thyristor firing mode
• the frequency used (50 or 60 Hz).
These miniature switches and the configuration jumpers are located on the driver board.

The positions of the miniature switches correspond to:
1 - switch lowered (ON position)
0 - switch raised.
Unless otherwise specified in the order, the thyristor units are delivered with the following configuration:
• the input configured for 4-20 mA
• the thyristor firing mode set to firing angle variation (Phase angle)
• frequency 50 Hz
• the thyristor firing delay potentiometer set to the maximum : maximum start ramp (resistive load) and 90
°
firing delay (inductive load).
