Dead Bus Module D1

When the external dead bus contact is closed, module D1 (Figure
2-14) determines when the bus is dead, and acts upon this
determination (if the breaker is detected open) by initiating a close
breaker signal. This signal is terminated as soon as the sync
acceptor recognizes the breaker as having closed, or when 100
milliseconds have passed (whichever occurs first).

The VOLTS control defines a dead bus condition by establishing a
voltage threshold between 10 and 40 Vac.

The DEAD BUS indicator is an LED that lights whenever the bus
voltage is below the control setting.
