The transformer/rectifier is operated via the connected 7" operating panel
(exception: battery cut-off for lay-up, see below).
In normal operation, no operating steps are required on the transformer/rec-
tifier.
In following cases, adjustments are required:
⚫ For initial commissioning.
⚫ When the battery type is changed.
⚫ When accessories are retrofitted.
This adjustment work must be carried out by an authorised service centre.
Together with the control unit SCU and the BUS modules, the transfor-
mer/rectifier EBL 402 forms the central control and power supply system for
all 12 V appliances in the electrical system on board of the vehicle.
⚫ The transformer/rectifier charges the living area battery. The transfor-
mer/rectifier charges the starter battery with a float charge only.
⚫ The transformer/rectifier monitors the voltage in the living area battery.
⚫ When the vehicle engine is turned off, the transformer/rectifier separates
the starter battery electrically from the living area battery. This prevents
the 12 V living area appliances from discharging the starter battery.
⚫ The transformer/rectifier controls and monitors connected solar charge
regulators and auxiliary charging units.
⚫ The transformer/rectifier supplies all BUS modules and the connected
sensors and appliances with current.
⚫ Via BUS lines, the transformer/rectifier provides the communication with
the BUS modules, the panel will and the control unit SCU.
The transformer/rectifier only works in conjunction with a BUS-capable pa-
nel.
The power in the transformer/rectifier is divided into charging current and
current to the appliances. The charging current is always just the portion that
is not being used by any appliances. If the current to the appliances exceeds
the current available, then the living area battery is discharged.
Some circuits are still supplied with current even when the 12 V power
supply is switched off on the panel. These are all appliances connected to
the 12 V constant positive, for example:
⚫ Entrance step
⚫ Heater
When the vehicle is laid up, these appliances are also disconnected from
the battery.
◼ Switch off the 12 V power supply on the panel.
◼ Move the battery cut-off switch (Fig. 143,2) to the "Aus" (Off) position on
the transformer/rectifier EBL 402.
◼ Move the battery cut-off switch (Fig. 143,2) to the "Ein" (On) position on
the transformer/rectifier EBL 402.
◼ Switch on the 12 V power supply on the panel.
Further information can be obtained in the manufacturer's instruction
manual.
