Votronic 1256 Bedienungsanleitung
Installation and Operating Manual
LCD Voltmeter S No. 1256
The Votronic LCD Voltmeter S is designed for voltage control of starter battery and board battery in campers, special
purpose and intervention vehicles. The voltage (Volts) is displayed accurately in steps of 0.1 V.
Appearance and dimensions of the Voltmeter are adapted to the VOTRONIC modular system. The VOTRONIC modular
system includes the tank display units (fresh and sewage water as well as feces), the LCD series (solar computer, battery
computer, ammeter and thermometer), as well as the switch and fuse panels.
Please read the mounting instructions and operating manual including the safety regulations
completely prior to starting connection and start-up.
Installation and Connection:
Display Unit
The small mounting depth (approx. 27 mm) of the electronic system allows flush mounting into furniture boards to
ensure, that an optimum installation place can always be chosen. The clear opening of the cutout is min. 71 x 66 mm to
ensure safe alignment of the front panel. Please use the delivered drilling jig, which has been designed to consider
combination with further display panels.
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.
Terminals
Connection +Board
For the voltage measurement of the board battery a direct connection from this terminal to the positive pole of the board
battery must be made. The cable is to be protected by means of a 3 A fuse directly at the battery. The cable cross-section
should be 0.75 mm², at least. This connection is also used for the current supply to the Voltmeter.
Connection +Start
For the voltage measurement of the starter battery a direct connection from this terminal to the positive pole of the
board battery must be made. The cable is to be protected by means of a 3 A fuse directly at the battery. The cable cross-
section should be 0.75 mm², at least.
Connection +Board
For the voltage measurement of board battery and starter battery a direct connection from this terminal to the negative
pole of the board battery must be made. The cable cross-section should be 0.75 mm², at least.

Initial Start-up
The Voltmeter is ready for operation, as soon as all electric connections are made and the voltage of the board battery is
available at the corresponding terminal.
Basic Setting:
The existing system voltage (12 V or 24 V) must be set.
Operation LCD Voltmeter S
Key 1: Changing the Volt displays,
Key 2: Display on/off.
Menu (3s)
Activation, Deactivation
The unit is optimized for extremely current saving operation and offers three operation modes.
Stand-by: During stand-by mode the display is empty.
Display with and without illumination: As soon as the voltmeter is operated, the display illumination will be switched-on
and will remain activated for 3 minutes. If there is no operation during this time, the illumination will be switched-off
automatically. The display continues showing the same data. The display illumination is reactivated by pressing any key.
The proper function of the key will be effected by pressing the key a second time.
Voltage Displays
Use the key 1 to scroll between the voltage displays starter and board battery.
Voltage:
The voltage of the battery will be displayed.
The markings at the lower edge of the display point to the corresponding battery.

Voltmeter Settings:
The menu for settings of the Voltmeter functions can be
called, if the display is set to Voltage (V) and the key 2 is
pressed and hold for more than 3 seconds until “Set” is
flashing.
In the menu, key 2 is used to save the corresponding
setting and to jump to the next menu item.
Adjustment of the System Voltages:
The nominal voltage rates for board and starter battery
must be set once. Switching between 12 V and 24 V is
possible for both.
Adjustment of the Background Illumination:
The background illumination can be adapted from bright
to completely dark in steps of 10 % according to the
requirements.
General Information:
Once a year:
Check the connection cable for correct contact and damage.
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.
Trouble-Shooting:
No display at all:
a) Reverse battery: Check!Battery is totally discharged, below 7 Volts: Recharge immediately!
c) Connection cable is interrupted, damaged, or it is not inserted: Check!
„Hieroglyphs“ on the display:
a) The internal check programs of the unit have found an (memory) error:
Withdraw the cable connector for 10 seconds. After that, an initial start-up is to be executed as described above.

Safety Instructions:
Safety Regulations and Appropriate Application:
The VOTRONIC LCD Voltmeter S had been designed according to the valid safety regulations.
Appropriate application is restricted to:
1. Control of commercial types of lead storage batteries (lead-acid, gel, AGM), as well as LiPoFe, of the indicated
nominal voltage and of connected consumers in fixed installed systems.
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.
4. With a rear insulating cover of the display unit.
Never use the unit at locations where the risk of gas or dust explosion exists!
Open-air operation of the unit is not allowed.
Cables are always to be laid in such a way that damage is excluded. Observe to fasten them tightly.Never lay 12 V
(24 V) cables and 230 V mains supply cables into the same cable conduit (empty conduit).
Check live cables or leads periodically for insulation faults, points of break or loosened connections. Occurring
defects must be remedied immediately.
The unit is to be disconnected from any connection prior to execution of electrically welding or work on the electric
system.
If the user is not able to draw from the manual, which characteristic values are valid for a unit or which regulations
