Functions with DM50
The screens and functions of the DM50 are the same as the screens of the DC50.
A DC must be connected to one, and only one, BM50. Even if the unit is connected to the pLan bus, the screens of the
DC50 will only apply to the configured BM50.
One DM50 may be connected to 12 units with the pLan bus. The screens of the DM50 will apply to one of the BM50
alternately.

On the bottom line of the BM50 the symbol ‘#’ indicates the BM50s
identified on the pLan bus (number 1 on the left, up to number 12
on the right)
A unit that is disconnected or switched off cannot be displayed
by the DM50.
The number in brackets at the bottom left indicates the number
of the BM50 currently connected to the DM50.
In the event of a fault on one or other of the BM50s identified, the
‘Prg’ button is illuminated in red and the symbol ‘#’ for the units
concerned flashes.
