DT 220 B control and switch panel instruction manual
When a leisure battery is replaced in the menu "Settings" the nominal capa-
city has to be set, the corresponding value of the new battery has to be set
and saved by pressing the "OK" button. This must be carried out, even if
the capacities of the new and the old battery are identical. This resets the
control and switch panel to the "Battery new value" for the max. accessible
capacity (80% of nominal capacity) (see also section 5.4.2.2).
The control and switch panel is equipped with a real "level display" for the
leisure battery. The display of the battery capacity gives direct information on
how much power is stored in the battery.
The motorhome can run for 3 days (without solar or fuel cell) after a full
charge (100 %) without having to be connected up to a 230 V supply. 40 %
battery capacity will now be displayed (for example). This means:
The battery can supply the motorhome with power for about 2 more days.
F
Other
functions:
The capacity display will be automatically reset to "full" when the full
F
charge state is reached.
A warning will be generated if the battery capacity drops to approx. 15 %.
F
Automatic determination of the maximum possible battery capacity (in %)
F
for defined "discharging" of the battery.
Charge request if the last full charge was more than 20 days ago.
F
Variable nominal capacity setting (e.g. if a battery with a greater capacity
F
is retrofitted).
The battery should be recharged at regular intervals. Otherwise a request
Y
will be issued ("Charge" and "Date", see Chapter 5.6.1 as well).
Solar current
The solar current display is only available if a Schaudt GmbH LRS ...
Y
solar charger is fitted and the "Read solar current" option is active.
Solar charging current will be displayed when it rises above 200 mA. The
"Sun" symbol will be displayed if the sum of the solar charging current in the
leisure battery and in the starter battery is greater than 1 A.
Battery monitor
The battery monitor (with dynamic voltage threshold) continually checks the
leisure battery. It will be switched off "earlier" for small discharging currents
than for larger currents. This enables better total discharge protection to be
realised. Monitoring continues even in the switched off state. A warning will
be displayed if it drops beneath 12.0 V (depending on the current being
drawn) (see Chapter 5.6 "Alarms").
The battery monitor will immediately switch off all 12 V consumers if the lei-
sure battery voltage continues to drop and actually drops below 10.5 V. The
control and switch panel also shuts down automatically. Only the frost pro-
tection valve will continue to be supplied with power so that it remains clo-
sed. All of the switching states and the battery capacity setting will be saved
before switching off and these will be reset after switching back on.
