Operation
Control and Display Panel
①
The display shows the actual data (time, level, voltage, ...) as numerical values. The menu level and the
displays of the board battery additionally show a bar graph on the left side. The measurement unit of
the displayed value is also shown on the display.
②
The desired information is shown on the display using the control keys of the battery computer, the
tank displays, the display units for thermometer or clock and of the solar computer. The adjacent LED
indicates the kind of information being currently displayed. To change the display, such as between
board battery and starter battery, press the key adjacent to the corresponding LED. In the menus for
board battery and solar computer, different values can be displayed consecutively.
Use the arrow keys on the right side of the display to change to the next or previous page.
③
Control keys and remote control keys for display ON/OFF, main switch and pump relay.
The LED lamps adjacent to the keys indicate the corresponding state.
Display Illumination:
The illumination of the display is activated automatically when pressing any key. It will be turned off
automatically after 3 minutes, if the main switch is switched-on. If the main switch is switched-off, the
illumination will be turned off already after 20 seconds to avoid an unnecessary load of a possibly
empty battery.
The illumination can also be switched-off manually by shortly pressing the main switch (see figure on the left
side).
The brightness of the LED lamps is coupled with the illumination of the display. If the display is dark, also the
LED lamps will be dimmed to a minimum.
Brightness Display and LED:
The brightness of the display illumination and of the LED lamps can be changed at any time
by pressing and holding (3 seconds) the arrows keys. The settings will be kept in memory.
Main Switch:
The main switch will be switched-on or off by pressing and holding the ON/OFF key longer (>3
s). The state of the main switch is indicated by the adjacent LED "12 V". Please observe, that the
main switch will be switched-off automatically in case of low battery capacity or voltage (see
battery protector).
If the main switch had been switched-off, the illumination will be turned off already after 20 seconds.
Operation of water pump and USB charger is only possible, if the main switch had been switched-on. They will
be switched-off automatically, as soon as the main switch had been switched-off.

- 3 -
Water Pump:
The pump key switches the pump relay on or off. The state of the relay is indicated by the
adjacent LED. Operation of the pump is only possible, if the main switch had been switched-on.
It will be switched-off automatically, as soon as the main switch had been switched-off. The
pump cannot be switched-on, if the main switch had been switched-off.
Solar Computer:
The Solar Computer indicates the current operating state, the solar current, as well as the
solar power of the connected VOTRONIC Solar Controller. In addition, it is equipped with a
solar power meter.
Use the arrow keys on the right side of the display to change to the next or previous
page.
Current: The instantaneous current rate in Amperes (A) is displayed.
Capacity: The instantaneous capacity in Watts (W) of the solar system is displayed.
Solar Power Meter: The power being generated by the solar system is measured
continuously and will be displayed as ampere-hours (Ah), as well as watt-hours (Wh). If the
value 9999 Wh is exceeded, the display changes automatically to kWh. The meter readings
can be separately reset to zero at any time. Reset can be effected, if the corresponding
meter value is displayed and by pressing the key Solar for more than 3 seconds until (Set
----) is displayed.
Operating State Solar Controller:
Depending on the solar controller, the operating state of the solar controller is indicated by
the sun symbol.
-No sun: Solar power is not at disposal; the solar controller is in stand-by mode.
-Full sun: Solar power is at disposal, maximum possible charge
-Flashing sun: The controller limits the current because of a full or almost full battery to
avoid battery overcharging. For determination of the possible solar power, the battery
must be discharged by a consumer (such as lighting) until the solar controller stops
limiting the current and the sun symbol stops flashing.
Thermometer/Clock:
The thermometers indicate the inside and outside temperature.
Press the key "Thermometer/Clock" to change between inside and outside temperature or
clock.
The time is displayed in 24 hours format.
Setting of the time is effected by pressing the key "Thermometer/Clock" for 3 seconds,
until "Set" will be displayed at the upper edge of the display, and the hours of the time will
be flashing. Use the arrow keys to set the hours. Shortly press the key
"Thermometer/Clock" to set the minutes. The minutes will now be flashing and can be
changed using the arrow keys .
Tank Displays:
The tank displays indicate the levels (level height) of the fresh water and sewage water
tank as percentage.
Use the key "Tank" to switch between the display for fresh water tank and sewage water
tank. If the sensors had not been connected or are wrongly connected, the corresponding
tank display cannot be selected.
Current will only be supplied to the tank sensors, if the levels will be interrogated by a
keystroke. If the illumination of the display is switched-off manually, or if it switches-off
itself after a certain time, the display changes automatically to the actual time. Thus, an
unintended operation of the sensors and current consumption is avoided.

- 4 -
Battery Computer:
The Battery computer indicates all relevant values of board and starter battery.
Switching from board battery to starter battery and vice-versa is effected by pressing the
key "Battery".
Use the arrow keys on the right side of the display to change to the next or previous
page.
Voltage: The display shows the voltage in Volts (V) of the corresponding battery.
Current: The current display informs about the current load or charge of the battery. The
display shows the instantaneously measured current rate in Amperes (A) flowing into or
out of the battery. If the current flows into the battery, the display will show a positive
current value and the charging symbol "CHARGE". If the current flows out of the battery, it
is negative, and the value will be shown with a preceding negative sign.
Residual Capacity: The residual capacity of the board battery will be displayed in ampere-
hours (Ah) and as percentage (%). Additionally, it is displayed in form of a bar graph (like a
level).
Display of the Remaining Time:
The remaining time will be calculated from the residual capacity (up to the adjusted
switching-off threshold) and of the actual current. In case of very high current rates, an
adaption to the capacity value of the battery will not be effected. Thus, in case of high
current rates, the display of the remaining time is only of informative character.
It is calculated according to the following formula:
(Capacity switching-off threshold - actual capacity) / actual current.
If the battery does not supply current, a calculation of the remaining time is, of course, not
possible. Now the sign -.- will be displayed.
Battery Protector:
Combined with a remote-controlled main switch (e. g. Switch Unit 100), the VPS Jupiter system has an
integrated protection against deep discharge which can be adjusted individually.
If the residual capacity drops below the adjusted residual capacity, the main switch (terminal) will be switched-
off automatically. It can be switched-on manually at the display panel (see main switch). Additionally, a restart
threshold can be set in the menu. As soon as this threshold is exceeded, the main switch will be switched-on
automatically. This threshold is factory-adjusted to 101 %, which means that an automatic activation is
prevented.
The second protective measure is the disconnection in case of low voltage. If the voltage drops below the
adjusted low voltage of, for instance, 10.5 V, for 30 seconds, the main switch will also be switched-off
automatically.
If the main switch is disconnected, the pump and the USB charging socket will also be switched-off at the same
time.
A short audible alarm signal will be given by the display panel.
Cleaning:
We recommend to use a damp microfibre cloth with pure water or, if required, with water with a few soap.
Take care, that no liquid flows along the display screen or the edges of the front panel.
Never use solvents, aggressive household cleaners, and scratching or abrasive agents or objects to
clean the front panel and particularly the display itself.

- 5 -
Installation and Connection:
All terminals are designed in such a way, that end-type terminals are not required. The 9-pole terminal at the
display panel is a plug-in terminal, which can be removed for installation. The cable cross-sections can be
drawn from the plan. Since fuses serve as cable protection, they must be positioned as close as possible to the
battery.
Smart Shunt
The smart shunt measures the battery voltage and the current for determination of the residual capacity
(level) of the battery. Furthermore, it can measure the voltage of the starter battery, and it is equipped with a
terminal for control of a main switching relay, such as the Votronic Switch Unit 40.
Any battery current should flow over the smart shunt. Therefore, it is to be installed directly near the battery
(batteries). Correct calculation of the actual battery capacity is only possible, if all currents are detected
correctly by the smart shunt.
Ground straps at the connecting screws M8 of the smart shunt are to be screwed in such a way, that one
connection is connected to the negative pole of the battery and the other one with the car body. The
connections at the negative pole of the battery and at the body / ground should not be mixed up (see
connection plan). Otherwise, a charge is measured as discharge and vice-versa.
Never connect anything to the brass screws of the electronic system of the smart shunt.

- 6 -
The connections at the smart shunt should always be tightened firmly to avoid any transition
resistance. Permanent high load might result in heating of the smart shunt.
Except of the smart shunt, no further connection (e. g. of consumers or charging devices) should
exist at the negative pole of the battery or at the negative pole of the complete battery system!
The terminal of the smart shunt supplies 300 mA and serves for control of a Votronic Switch Unit. These units
are relays for high current rates, which do not require any current for holding, thus avoiding an unnecessary
load of the battery. Remote control of the terminal is effected from the panel. Thus, it can be switched-off and
switched-on manually. Furthermore, an automatic disconnection is possible, when dropping below the
adjusted residual capacity or battery voltage (protection against deep discharge).
Display and Control Panel (Display Panel)
Choose a central and easily accessible location in the living area for installation of the display panel. This will
facilitate the legibility of the information and the operation of the functions. The clear width of the cutout is at
least 184 x 57 mm.
If possible, the rear cutout opening should be covered with electrically nonconducting material to ensure
efficient protection of the electronic system and full utilization of the storage space, which might be located
behind. Ensure the ventilation of the electronic system.
The display panel will be connected to the smart shunt via a 6-pole control cable. The connection is executed
ready to be plugged in, and the cable should be laid according to the safety instructions.
Supply of the display panel including USB charging socket and pump relay is effected directly from the battery.
The temperature sensors, as well as the optional tank sensors use the delivered 5-pole distribution terminal as
common minus connection. For this terminal, the wire-ends must be stripped for a length of 11 mm.
Water Pump
The relay contact for the water pump is switched by a key at the display. The maximum admissible load of the
output is 16 A.
Outside Temperature Sensor
Install the delivered temperature sensor for outside temperature at a protected
location, if possible below the vehicle. Ensure that the installation place is not
influenced by any source of heat (hot exhaust, asphalt etc.). Should the length
of the connection cable at the temperature sensor be not sufficient, it can be
extended to the desired length by a cable of min. 0.75 mm².
The temperature sensors are protected against reverse battery and can be
connected with any polarity.
Inside Temperature Sensor
For installation, remove the cap from the temperature
sensor and insert the sensor with the cable from behind
through the mounting hole (7.5 mm). Reinsert the cap on
the sensor after that and push both into the mounting hole
from the front. The temperature sensors are protected
against reverse battery and can be connected with any
polarity.
Tank Sensors
As option, up to two Votronic Tank Sensors can be connected and used. All Votronic Tank Sensors of the
product category "Mobile Leisure Time" are compatible. The connections of the tank sensors are to be coupled
to the display panel, as indicated in the connection plan. The cross-section of the cables should be min. 0.75
mm². The current supply to the tank sensors by the panel is restricted to the time, in which the levels are
interrogated.

- 7 -
Solar Controller
As option, a Votronic Solar Controller from model 2014 can be connected to the panel by means of a 6-pole
control cable.
Initial Start-up
The smart shunt is ready for operation, as soon as all electric connections at the smart shunt and the display
panel are made. Besides, the following basic settings must be made compulsory.
Basic Setting:
The nominal capacity of the board battery must be set.
The used battery type and its nominal voltage must be set.
The switching-off thresholds and switching-on thresholds can be adapted.
The audible alarm can be deactivated.
The actual time must be set.
The nominal capacity is indicated in Ah, and it is imprinted on the battery. If several Ah-values can be found,
use the value ....Ah (20 h). If several batteries have been combined to a 12 V battery system, add the Ah
values. Total capacity for 2 batteries at 110 Ah is 220 Ah. This value -220 Ah- must be set.
After the basic setting, the battery must be charged using a suitable charger (in case of mobile
homes using the existing board charger) for a duration of 24 h. This is absolutely required, so that
the battery computer is able to recognize 100 % full charging required for starting. If the smart
shunt loses its voltage supply (battery disconnected etc.), also proceed as described above.
After adjustment of the battery capacity and after loss of the supply voltage, the residual capacity will be
estimated automatically by means of the battery voltage. After that, the battery must imperatively be charged
for at least 24 hours with a suitable automatic charger to ensure correct display of the capacity. Only when the
battery had been fully charged, the system adjusts itself to "its" battery, and the display will show 100 % or the
residual capacity of the battery in Ah. The initial settings and the full charging of the battery are absolutely
required to ensure proper capacity indication, and it must be repeated whenever the unit or the battery had
been disconnected!
