Depassivation
If the main battery is stored for a long time, especially at storage temperatures of more than 30 °C, the battery may
become passivated. The battery can then not immediately supply the network node with sufficient energy.
If the network node detects a passivated battery, it automatically starts a depassivation cycle. This is signalled by a
flashing LED on the front panel.
The depassivation can take a few minutes. Afterwards the network node starts in the operating mode
IdLE
.
If the battery is severely undercooled, passivation can also occur in other modes (for example in installation mode)!
3.8 M-Bus connection
At each network node, the M-Bus can be connected temporarily or permanently (permanently installed). The
connection is made using the plug on one of the two connectors of the M-Bus service connection (3). The plug is
included in the scope of delivery.
Note
An M-Bus gateway and an M-Bus service tool must not be connected at the same time!
