This alarm sets the maximum time that a shore connection may be connected in
parallel to a shaft generator.
The power management system normally prevents a shore connection and a shaft
generator from connecting in the same section. This alarm is a safety feature, since
it is possible to for an operator to manually connect a shore connection and a shaft
generator. This can occur if the second equipment's breaker is closed manually, or
if the tie breaker between the two sections is closed manually.
This alarm is triggered when a shore connection and a shaft generator are
connected to the same busbar for longer than the delay time. The alarm delay timer
starts when the second equipment connects.
