Figure 27c
– BM 25 mode : Radio Signal Strengh
When is displayed, the BM 25AW has 100% of the signal and the radio
communication is very good.
When is displayed, the signal strengh is less than 20% although BM 25AWs are
still communicating.
When is displayed, no communication is established, BM 25AW shows 'COMM
ERR' and goes into fault (see case #1 from table of events).
Adding a BM 25AW on an existing network
In
BM 25
mode, the network is automatically built. Each BM 25AW with the same
network ID is automatically included as long as it communicates with at least one BM
25AW belonging to the same network.
To add a new BM 25AW to an existing network, simply turn the unit on, activate the
radio communication and, if applicable, set the network ID.
In MODBUS mode, you must set the address number (Slv Nb), set the network ID
(Channel) and configure, if applicable, a new input on the controller.
Removing a BM 25AW from an existing network
In BM 25 mode
■
turn the unit off
■
or deactivate the radio module from the maintenance menu.
In both cases, before communication stops, the BM 25AW broadcasts a last message
to inform the other BM 25AWs on the same network that it will be removed.
In Controller mode
To remove a BM 25AW from an existing network, just switch the controller channel off,
then turn the BM 25AW off or deactivate the radio module if you still need to use the
BM 25AW in local.
