6.4.2 BMS Slave
All IRDH275B are factory set to slave mode (address 3). In a BMS network,
one address must be selected from the address range 2...30 for each slave.
There may be no gaps of more than five subsequent addresses, so that all
slaves can be scanned by the Master. For IRDH275B a BMS address can be
selected from the address range 1...30. When assigning the addresses, also
other devices such as the EDS47x-12 must be considered.
The correct reception of BMS data is indicated by a flashing point on the dis-
play on the right of the measuring pulse indication.
Flashing point:
BMS data received
If no flashing point appears, it may be attributed to the following:
z
no Master available in the network
z
more than one Master available in the network
z
RS485 interface (terminal A/B) not connected or reversed
