Mode
Two operating modes are available: Phase Lock Loop and Anticipatory. In both modes, the BE1-11g
adjusts the frequency and voltage of the generator to match that of the bus (mains) at the proper relative
phase angle, and then connects the generator to the bus by closing the breaker. Anticipatory mode has
the added capability of compensating for the breaker closing time (the delay between when a breaker
close command is issued and the breaker contacts close). The BE1-11g controls the slip frequency
difference between the generator and the bus, and then calculates the advance angle that is required to
compensate for the breaker closure time.
Synchronization is accomplished using the Raise and Lower logic outputs for the voltage and frequency.
These logic outputs can be set to continuous or proportional. Continuous mode turns the required logic
output on until either it is in the synchronization window or overshoots it. Proportional mode toggles the
contacts based on the respective Pulse Width setting, Pulse Interval setting, and calculated error.
