Figure 7.38: Using ProLogic to give Trip Command via External Input
ProLogic 5: This equation provides indication via the relay HMI display, that
the Recloser has locked out.
Figure 7.39: Recloser Lockout
ProLogic 6: This equation resets the 79 Lockout. It uses Virtual Input 1 “SCA-
DA Reset 79" to simulate a SCADA Lockout Reset command. In this case, this
is done by closing the Main Breaker Status (Out 5), then Auxiliary Breaker Sta-
tus (Out 6) to simulate main and auxiliary breaker closed status. This latching
function resets when the 79 Lead Lockout goes low.
