BÜTTNER ELEKTRONIK – Batterie-Control-Booster MT BCB 30/30, MT BCB 40/40, MT BCB 60/40
22
Pulsing Unit
(DIP 7) Training function for lead battery systems
DIP switch position – right: Pulser activated
DIP switch position – left: Off
In DIP switch position Pulser, the pulsing mode starts automatically
if neither mains- nor booster- charging takes place.
Trains the board batteries (only lead acid, gel, AGM) with very short but
powerful current pulses and counteracts creeping sulphation.
The average power consumption remains low. Automatic shutdown when
voltage at the BOARD terminal: < 12.00 V.
• If the LiFePO
4
battery type is set, the pulsing unit is always deactivated
• If the vehicle is to be parked for a longer period of time, charging mode
at the mains socket is always to prefer, since not only the board battery is
kept charged, but also the starter battery.
BMS
(DIP 8) Control signal for LiFePO
4
-batteries
BMS: for 12 V – control signal of a LiFePO
4
-battery (high active)
BMS: for 0 V - control signal of a LiFePO
4
-battery (low active)
If the BMS (battery management system) of a LiFePO
4
battery
is equipped with a “charging stop/warning/error” output,
this can be connected to the BCB switching input “BMS”
on the 9-pin terminal plug.
Depending on the switch setting of DIP 9, the BMS can either
• stop the charging process (DIP 8 - A), or
• switch the BCB in lithium-maintenance-idle mode (DIP 8 - B).

-batteries with BMS-signal output
A: Signal at the BCB input plug BMS
(together with DIP 8) charger
switches to security supply voltage 12.8 V (charging stopped).
Consumers will continue to be supplied with power at 12.8 V
and the battery is supported to prevent discharge
B: A signal at the BCB input terminal BMS
(together with DIP 8) activates 13.2 V
