Power-loss Restart
The Terranova® 752A may be set to automatically restart high voltage operation after a power
interruption. If high voltage output was enabled before the interruption, high voltage operation
will commence once power to the control unit is restored. The safety interlock circuit must remain
closed throughout the entire process for a successful power loss restart.
The power loss restart function is changed via the internal DIP Switch S1. Although DIP Switch
S1 has eight individual ON/OFF switches labeled 1 through 8, only switch S1-2 is utilized. The
automatic restart function is by default disabled.
User should wait at least 15 seconds after turning OFF the
Terranova® 752A before removing the power cord
