Selfsupervision Contact
The Selfsupervision Contact contact (“SC”) cannot be configured. It is a changeover (Form
“C”) contact that picks up when the device is free from internal faults. While the device is
booting up, the “SC” relay remains dropped-off (unenergized). As soon as the system is
properly started (and protection is active), it picks up and the assigned LED is activated
accordingly (please refer to the Self Supervision chapter,
).
