Disables the 25A function when true. A pulse will stop and reset the 25A
function. Also, resets the element after a sync fail.
A pulse true initiates the synchronization process. It does not have to be
maintained to continue synchronization. If it is maintained and a sync fail
occurs, the element will not be blocked, but continue with a new sync
cycle.
True when the synchronization criteria is met.
Signals the breaker to close. True after the Status output becomes true.
True when the voltage monitor settings are met.
True when the 25A element is decreasing frequency.
True when the 25A element is raising frequency.
True when the 25A element is decreasing voltage.
True when the 25A element is increasing voltage.
True when the 25A has been initiated, and is not inhibited. The 25A is
inhibited when the generator or bus voltage is less than 10 V or 15 Hz.
A one-cycle pulse, true when the breaker is still open after maximum
close attempts.
True when the voltage magnitude between sources is less than or equal
to the Voltage Difference setting. If the Voltage Source > Voltage
Destination setting is enabled, the generator voltage must be at least
0.5% greater than the bus voltage.
