Figure 278: Autoreclose enable logic
Figure 279: Autoreclose initiate logic
A reclose initiate signal sends the scheme into the reclose-in-progress (RIP) state and
asserts the AR RIP operand. Once the breaker has opened, the scheme is latched into the
reclose-in-progress state and resets only when an AR CLS BKR 1 (autoreclose breaker 1) or
AR CLS BKR 2 (autoreclose breaker 2) operand is generated or the scheme goes to the
lockout state.
