Connection:

The BS can be used in situations where two batteries are present, for example
in boats, caravans and campers. The BS can also be used as a voltage-
dependent switch.
The BS is a microprocessor-controlled high-power mechanical switch. If two
batteries are used the BS will 'look' at the voltage of the primary battery. A
battery that is not being charged will (in a 100% charged condition) have
a voltage of approximately 12.6V (25.2V). When the vehicle or a boat is
started the voltage will slowly increase to the maximum charging voltage
of approximately 14.4 V (28.8V). Once the voltage has reached 13.2V (26.4V)
for a minimum of five s econds t he B S s witch w ill c lose a nd t he a uxiliary
battery will also be charged. As is usual in boats, caravans etc. all accessories
are connected to the auxiliary battery. When the vehicle/boat has stopped,
after a while the battery voltage drops and thus the switch opens again. This
happens when the voltage reaches 12.8V (25.6V) or lower for a minimum
of 60 seconds. Therefore the primary battery always remains 100% charged.
Bi-directional operation:
The Battery Separator has a second unique function. If in your application you
have a battery charger connected to your auxiliary battery (often the case in
boats and campers), once the voltage of the auxiliary battery exceeds 13.2V
(26.4V) for a minimum of 5 seconds the start battery is also charged. This is
a particular advantage if you remain stationary for a long period. In this
case your primary battery also remains in optimum condition and once the
charger is removed the switch will open of the voltage drops below 12.8V
(25.6V) for a minimum of 60 seconds.

Start Help:

If you wish to make use of the start help option the battery separator has yet another connection. If you connect the start help terminal (Status) via the start switch to
the plus terminal, the separator will also switch in the auxiliary battery during starting. Instead of the start switch an optional remote control panel can be supplied.

Voltage dependent switch:

In some cases it is desirable that power is only available via an extra terminal when the vehicle is operating. The BS is also very easy to use in this situation by
connecting one terminal (A1 or A2) to the primary battery and the other terminal (A1 or A2) to your accessories. If the battery is now charged the battery voltage will
quickly rise above 13.2V (26.4V) and the switch will close and the accessories will be powered.

Battery / Accessories protection:

All our battery separators have a unique safety system for the auxiliary battery and the accessories. If the generator voltage regulator becomes defective, the charging
voltage can rise well above the allowable battery voltage. This can/will damage the battery and the attached accessories. However the BS will immediately open the
switch and prevent this unnecessary damage from occurring!
