Functional description
With the button the cursor is moved.
submits the value and the device will set it. Abort with
without submitting the value.
For the adjustment of the overvoltage threshold it is
required to access the device setup menu. See section
„Menu: Device setup“.
Powering the device
The device does not feature a power switch. When con-
necting it to mains, it is immediately ready to work.
After switching mains off the device stores the last state
(selected mode, output condition) in order to restore it
automatically at the next start. Thus it can continue to
work after an interruption like a blackout etc.
Battery voltages and charging currents
The battery charger only allows to charge batteries
that meet the device‘s specications regarding output
voltage. The maximum charging current is equal to
I
Nom
.
Attention! Before connecting or disconnecting bat-
teries it is imperative to check if charging has been
stopped.
Starting a charging
The charging is started by pushing button . The
battery will then be charged according to the selected
battery prole and with the corresponding charging
characteristics, as depicted in section „Charging pro-
decures“. The display will indicate the actual charging
phase by a status text:
Precharge Precharge phase (all types)
Normal charge Normal charge phase (all types)
Trickle charge Trickle charge phase (lead only)
Attention! It is imperative to select the proper batte-
ry prole before charging! It is also recommendend
to modify the battery prole to meet the specica-
tions given by the battery manufacturer!
Stopping a charging
By pushing the button the charging is paused at
any time. The charging can then either be continued
with button or aborted with . The output
is then switched off and the time count stops. The
display remains until a new charge is started. This is
used to display sort of a summary for the last charging
procedure with total time and battery charge. Further-
more, the status text Charging nished indicates the
condition.
Using the analogue interface
The analogue interface allows to monitor the device‘s
output values (voltage and current) and the condition
(errors) remotely. It can also start or stop a charging.
The monitor outputs represent the nominal values of
the device from 0...100% with voltages of 0...10V.
The temperature sensor is also connected to the ana-
logue interface. The clamps are suitable for 20 - 26
AWG wires, dismantled at least 10mm.
See the table below for pin assigment and levels.
Error messages and alarms
While the device is operated as charger, errors and
alarms are indicated with a full status text in the display.
In Power Supply mode, the alarms are abbreviated
and indicated by an alarm symbol. Also see table on
the next page.
In order to continue working with the device, alarms
have to be acknowledged by the user. This is done by
pushing the button . If the cause of the alarm is
not present anymore, the alarm display is cleared and
the alarm is deleted from the internal alarm buffer.
The alarm buffer can also be read out via a digital
interface.
Note: Alarms are only put into the internal alarm buffer
as a code number. See table below.
Alarms are also put out as signal on the analogue inter-
face, pin 9. See section „The analogue interface“.
