8.7 Lightning Protection
The transient voltage surge suppresser (TVSS), located in the load center, reduces the brief surge
induced into the power lines when lightning strikes in the vicinity of the scoreboard. A varistor in the
power lines to the driver logic also helps to protect this circuit by reducing such surges.
The use of a disconnect near the scoreboard to completely cut all current-carrying lines significantly
protects the circuits against lightning damage. The National Electrical Code also requires it. In order for
this to provide protection, the power must be disconnected when the scoreboard is not in use. The
control console should also be disconnected from power and from the signal J-box when the system is
not being used. The same surges that may damage the scoreboard’s driver can also damage the
console’s circuit.
8.8 Replacement Parts

9.15 for a description of Daktronics Exchange and Repair and Return Programs. Important: When the
lamp drivers are replaced, plugs P25 and P26 (if present) must be removed from the old driver and
