Figure 226: Autoreclose scheme enable logic
Figure 227: Autoreclose scheme initiate logic
A reclose initiate signal will send the scheme into the reclose-in-progress (RIP) state and
assert the
operand. Once the breaker has opened, the scheme is latched into the
AR RIP
reclose-in-progress state and resets only when an
(autoreclose breaker 2) operand is generated or the scheme goes to the
AR CLS BKR 2
lockout state.
