Remarks:
• Recommendation for installation:
Quick and easy installation type when using the optional cable set (item no. MT 93080) for MT
BCB 30-30
-20
and MT BCB 40-40
-30
. For this purpose, the charging cable needs to be separated
at a suitable point and both cable ends to be connected at each side of the terminal block. The
pre-wired cabling needs to be connected to the BCB and the board battery.
• The high load relay (86) can be controlled either via the TR output from the BCB or with the D + /
ignition key (terminal 15) signal.
• Special case:
With some manufacturers of motorhome electronics (Nordelectronica NE148/185) the in-
ternal battery separator relay is only activated a few seconds after the D + signal! In order to
avoid interruption of the on-board supply, the high-load relay EBL may also only open with a
time delay after the battery separator relay has closed. For this reason, the high-load relay EBL
(86 orange cable) is activated with the TR signal 10 s delayed from the D+ signal.
• DIP switch setting for operating mode on V
• With LiFePO
4
board batteries, temperature-related, controlled charging is always ensured, even
at extreme temperatures (<0°C and >50°C).
• When connected to the mains, the board battery will be charged and the starter battery be
maintained in charge with 4 A, 5 A or 10 A, depending on the BCB model.
• In mains operation, the BCB supports the existing charger and the charging currents are adding
up. The temperature-controlled charging can only work correctly if the originally present char-
ger also has temperature compensation. If this is not the case, we recommend deactivating
the existing charger in order to achieve the optimal service life of your high-quality battery. In
particular, when using LiFePO
4
board batteries, the originally present charging devices must be
deactivated, especially since they also do not have lithium battery charging characteristics.
• With the EBL (Schaudt), the charger can be deactivated by removing the fuse “charger”. If the
power cable remains plugged in, the power detection signal continues to be available in the
control unit. In the case of CBE equipment, one cable from the charger output to the CBE distri-
bution can be interrupted in order to disable the charging function, but to receive the “mains
present”-signal on the board control panel. If necessary, when disabling/removing the CBE
charger, connect the BCB output “Ntz” to “J10” in the CBE distribution box.
