Handling the device

Application of the analogue interface

Charging start/stop or output on/off

Digital inputs (DI)

Before the charging can be started remotely, the de-

vice is required to be set into remote control (pin 7).

In „Power Supply Mode“, pin 8 is used to switch the

power output off and then on again. In this mode, the

output can be whether the remote control is active or

not.

In battery charging mode the pin is used to start or stop

the charging again.

Reference is digital ground (DGND).

Caution! If pin „Rem-SB“ is already pulled to low when

switching to remote control, then the charging will start

immediately.

Monitoring the device condition

Digital outputs (DO)

For clarication only, no real schematic example!

The outputs are quasi open collector outputs with a

pull-up resistor to Vcc. The maximum input voltage

must not exceed 30V and the maximum input current

must not exceed 20mA.

With this, also relays or LEDs can be used to indicate

the status without the necessity to amplify.

Reference is digital ground (DGND).

Monitoring voltage and current

Analogue outputs (AO)

The analogue monitoring outputs put out 0...10V which

corresponds to 0...100% of the nominal values.

Reference is analogue ground (AGND).

Temperature sensor input

Analogue output (AO)

The temperature sensor alters the charging voltage

according to the ambient temperature of the battery, if

placed in proximity, or to the battery surface tempera-

ture if placed directly on the battery.

It is important to only use sensors with 10mV/K. Allowed

temperature range is -15°C...50°C.

The included sensor is a LM335, pin assigment as

shown above. Always connect with correct polarity

according to the wiring scheme.
