Series IED stage information is divided into two sections.
Starting and tripping signals of protection stages are connected to physical outputs in Direct Output Control menu. It is possible to
connect to output relay or to start- trip- or user configurable LED. In case when stage is internally blocked (DI or other signal) it is
possible to configure an output to indicate that stage is blocked. Connection to outputs can be either latched |x| or non-latched x.
Stage blocking is done in
Blocking Input Control
menu. Blocking can be done by using digital inputs, logical inputs or outputs, stage
start- trip- or blocked information or by using object status information.
