When EB500 powered by B+ and B-, there will have excitation output on F+ and F-. The excitation output will be
terminated when AC1, AC2 reach 30VAC or the Flash time is reach flash timer setting. If re-excitation is required, the
B+ and B- must be powered off and then re-powered.
The Maximum Excitation Flash current can be set by A, B, C terminal (selected by jumper)
