Figure 115: Pairing the local HMI with the relay
Figure 116: Pairing the switchgear HMI with the relays
After successful pairing, the LHMI Home page opens.
If Pair is selected while connecting to the first relay in a switchgear,
the SHMI attempts to pair with all the relays it finds and is able
to connect and login to within the switchgear. If pairing is at first
skipped but needed later, initiate the connection process again by
typing in the IP address of one of the relays and choose to pair.
Optionally, it is possible to login and pair each relay individually.
If the pairing is skipped, the LHMI can be used for monitoring
purposes only. Pairing can be initiated later via the drop-down menu.
