ANSI MEDIUM VOLTAGE METAL-CLAD DIGITAL SWITCHGEAR

Protection relay

Check the connection status of protection relays
via PCM600. Open the project provided by the
Engineering function responsible for
programming the relays and select the protection
relay for which you want to check the connection.

If the connection between the PCM600 and
protection relay is established, a green tick mark
is shown next to the protection relay icon. (Note:
If no programing record is available, then contact
the Engineering function responsible for
programming the relays to obtain this file.)
