Installation and Operating Manual
Duo Storage Battery Tester S 12 V Order No. 1245
The Votronic Duo Storage Battery Tester is designed for the voltage metering of vehicle and board
battery in high-quality campers and fire-fighting and intervention vehicles.
Please read the mounting instructions and operating manual including the safety regulations
completely prior to starting connection and start-up.
The compact and robust unit displays two voltage rates, either
of the board battery or of the starter battery. It represents
clearly the most interesting range of the battery voltage, from
total discharge up to maximum charging voltage.
The luminous spot display supplies a quite precise display of the
battery voltage rates, since also the intermediate values are
clearly legible due to the different brightness of the adjacent
luminous spots. At the push of a button, the voltage of board or
starter battery can be selected, or the display can be switched-
off. In case of low battery voltage rates, red pilot lamps indicate
that battery recharging is required.
The Duo Storage Battery Tester S is executed as panel version
matching to the VOTRONIC modular system (identical height 85
mm). The combination with units of the VOTORNIC modular
system, such as the tank displays S, the LCD displays S, as well as
the switch panels and fuse panels S, is a useful application. The
units can be combined perfectly with regard to appearance, and
their installation is easy (see example modular system).
Installation:
Choose a well visible and easily accessible location in the living area for installation of the unit. The installation place in
the front panel of the furniture should be chosen in such a way, that the contrast of the display be not hindered
(sun light).
The electronic system’s small mounting depth of only 14 mm allows flush mounting into commercial furniture boards to
ensure, that an optimum installation place can always be chosen without losing precious storage space.
The clear opening of the furniture cutout should be slightly larger than the assembly dimensions of 29 x 62 mm to ensure
safe alignment of the unit’s front panel.
If several VOTRONIC units are applied, use the delivered jig for marking. The drilling jig facilitates positioning
and reduces the expenditure of installation, since time-consuming measuring for alignment is not required.
The rear cutout opening should be covered with electrically nonconducting material (e. g. plastic plate, poplar
plywood, or similar material) to ensure full utilization of the storage space, which might be located behind
Make all electric connections, place the Duo Storage Battery Tester S centrically in the cutout, and use the delivered
screws for fastening.

Connection Plan:
Configuration of Connections:
1 = Board Battery “-“ (Minus) or
Body-Ground
2= Board Battery “+” (Plus)
3= Starter Battery “+” (Plus)
Recommended Minimum Cable Cross-Sections:
Cable Length up to 2 m: 0.5 mm²
Cable Length up to 5 m: 1.0 mm²
Cable Length from 5 m: 1.5 mm²
Ensure that cable length is sufficient to facilitate the
installation.
Carefully screw down stripped cables with all single wires
to the terminal observing that no single wires jut out
laterally.
The unit is protected from reverse battery (+ and - mixed
up).
Lead the cable up to the battery connections! By this,
incorrect measurements due to voltage losses at the
power distributors, cables etc. are avoided.
Cable Protection: Arrange the fuses for protection against
short-circuits close to the battery.
Note: Amongst others, the connections of the panel are marked with numbers. The numbering of all VOTRONIC
display units has been assigned systematically to the corresponding connections. Thus, connection of several
units is facilitated.
The cables in different colours help to avoid malfunctions due to mixed up connections.

Operation:
When pressing the key, the display will increment shortly to “15 V”, and “Board”, as well as “Start” will be lighting for
reasons of testing.
After that, the voltage of the board battery will be displayed, and the LED “Board” will be lighting.
If the key is actuated for a second time, it will be switched to the starter battery. The LED “Start” is lighting.
Actuating the key for a third time will switch-off the Duo Storage Battery Tester S.
If the starter battery is not connected, the lowermost LED “10.5” is lighting dimly at least brightness.
10 minutes after the last activity, the display will be switched-off automatically for reasons of power saving.
Display:
The voltage is indicated by a lighting LED on the scale.
Simultaneous lighting of 2 light-emitting diodes indicates a voltage between the corresponding values.
EXAMPLE: If the two LEDs “12.5 V” and “13 V” are lighting with identical brightness, the battery voltage is 12.75 V.
If the brightness of the light-emitting diodes is different, the battery voltage tends to the light-emitting
diode being the brighter one.
The range of operation of the lead battery 12 V is indicated by the red and green light-emitting diodes, and it is valid for
inferior to normal load (current consumption) of the battery. Green means o. k.!
If powerful consumers with high current consumption are used, such as inverters, the battery voltage might drop below
11 V.
However, if the display is in the red range without any battery load or in case of only inferior battery load, the
corresponding battery should be recharged immediately.
If the voltage "10.5 V" is reached, switch-off all consumers in order to avoid total discharge of the battery. Now,
recharging is highly recommended !
Several times of total discharge result in loss of capacity or in destruction of the battery!
Never leave lead storage batteries in discharged condition !
An efficient protection against totally discharged board batteries is ensured by installation of a VOTRONIC
Battery Protector, which effects an automatic separation of battery and consumers.
Battery Protector 40 (12 V, to 40 A load current), order No. 3075 or
Battery Protector 100 (12 V, to 100 A load current), order No. 3078.

Safety Regulations and Appropriate Application:
The unit has been designed according to the valid safety regulations.
Appropriate application is restricted to:
1. Fused battery direct voltage with nominal voltage 12 V or 24 V.
2. Technically faultless condition.
3. Installation in a well-ventilated room, protected from rain, humidity, dust, aggressive battery gas, as well as in
an environment being free from condensation water.
