Handling the device
Applications of the analogue interface
Charging start/stop or output on/off
Digital inputs (DI)
In Power Supply mode: Pin 8 („REM-SB“) is used
to switch the power output off or on. In this mode, the
output can be used whether the remote control is active
or not, like for an emergency off.
Attention! Does not work if the device is set to LOCAL
mode.
In Battery Charger mode: Before the charging can be
started remotely by pin 8 („RUN“), the device is required
to be set into remote control (pin 7, „REMOTE“).
In the device setup for the analogue interface, the
user can dene the logical levels for pin 7 and 8. After
the charging is started and the logical level of pin 8 is
inverted, the charging is paused. Another level inversi-
on at pin 8 will continue etc. The charging is only fully
stopped after the remote control is left by reverting the
level of pin 7.
Reference is digital ground (DGND).
Caution! When switching to remote control and if the
logical level of pin 8 is already set to the same level
as dened for „RUN“ (in the device setup), then the
charging will start immediately.
Monitoring the device condition
The digital outputs (pins 2, 3, 9 and 11) 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. Relays
are allowed.
Note, that the outputs can be „high“ or „low“ when
signalising their dedicated signal. This is dened in
the device setup for the analogue interface, at item
Analogue interface -> Outputs. The pins can only
sink current to DGND, not put out.
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 temperature of the battery.
The included sensor is a LM335, pin assigment as
shown below. Always connect with correct polarity
according to the wiring scheme.
Bottom view. Pin „ADJ“ is not used.
