Battery block monitoring
Mounting/connecting the
battery block sensors
After installing the battery terminal jumpers, con-
nect the battery block sensors. Pay attention to cor-
rect polarity. Connect the black minus cable with bat-
tery minus and the red plus cable with battery plus.
As the battery block temperature measurement is carried
out via the negative lead of the battery block sensor, the
battery block sensor housing does not need to have a heat
conducting connection with the battery block housing.
Retrofitting of BDM modules
For the subsequent installation of the BDM modules in
the DualGuard-S devices an adapter is required which is
clicked into the DIN rail. The DIN rail adapter supplies the
BDM module with 24V voltage and establishes the bus
connection to the ACU module.
1) Remove the ACU module from the DIN rail.
2-3) Click the DIN rail adapter into the DIN rail.
4) Snap on the ACU module.
5) Snap on BDM module or CAN bus adapter.
If the ACU module and the BDM module are mounted
separately, the CAN bus adapter must be installed next to
the ACU module for the bus connection.
The BDM module is then connected to the CAN bus
adapter via a 4-wire shielded bus cable.
