ECTIVE BB & SBB 29
Connections: Sensor Inputs and Terminals
Plug-in Terminal Strip: In case of limited space, the strip can be
withdrawn and reattached at any time for easy cable connections.
T T Measuring input for the temperature sensor of the supply
battery „Board I“. Connect a temperature sensor to the terminals „T
T“ (any polarity). Make sure to follow any instructions relating to your
temperature sensor.
Ss- and Ss+ A cable sensor allows for more a accurate measuring of
the battery voltage. This helps the Battery Booster to compensate the
voltage loss on the charging cable. If no voltage sensor is connected, or
the connection is interrupted, the default measurement program will
be used. If multiple batteries are used in parallel, connect SS- to the
negative pole of the first battery, and SS + to the positive
pole of the second or last battery.
D+ Control input of the dynamo for the charging converter (B2B-
Booster) operation ON / OFF: Connect the terminal „D+“ directly to the
existing signal in the vehicle. The „D+“signal is preferably to be used for
the „active dynamo“. If the D+ signal does not exist in the vehicle, the
signal „Ignition ON“ can be used for unit control. Attention:
When the motor is not running, the starter battery might be discharged!
Battery Temperature Sensor Connecting an external temperature
sensor to the „TT“ port, allows for a real-time measurement of the main
battery‘s temperature. Ensure that this measurement is not distorted by
any other heat sources, such as motor heat, exhaust, heater, etc. If no
temperature sensor is connected or the connection is interrupted, the
Battery Booster assumes a default temperature of 25°C.
NC No function.
