“Normal” source circuit breaker

QR : “Replacement” source circuit breaker

UA controller

DB101604

Inputs

UN : “Normal” source voltage

: “Replacement” source voltage

KT : order for forced-operation on R

KR : additional check before transfer

Outputs

KG :

order to the genset

SH :

load-shedding order

QN : “Normal” source circuit breaker

QR : “Replacement” source circuit breaker

Key

O: OFF (circuit open)

I: ON (circuit closed

: either ON or OFF.
