BMS slave
All isoPV devices 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 isoPV a BMS address can be selected from the address range 1…30. When
assigning the addresses, also other devices such as EDS4xx must be considered.
The receipt of the BMS data is indicated by a flashing point on the display 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:
•
No master available in the network
•
More than one master available in the network
•
RS-485 interface (terminals A/B) not connected or reversed
The following table gives an overview about essential alarm messages and the assign-
ment of the messages indicated on the display or alarm indicator and test combina-
tions, e.g. MK800.
The BMS function is completely available in the standby mode
(Stand-by: F1/F2).
