LCD Battery Computer 400 S with Measuring Shunt 400 A No. 1268
Precise and complete battery control for all commercial types of lead storage batteries in vehicles and boats.
The VOTRONIC LCD Battery Computer S calculates the exact charging state of the battery and displays the charging state
like a “fuel gauge for the battery”. In contrast to simple ampere-hour meters, the residual capacity will be determined in
ampere-hours (Ah) or the residual charge in % by means of programmed characteristic diagrams of batteries and will be
displayed as charging state.
Furthermore, the unit is equipped with a programmable terminal for connection or disconnection of consumers or further
energy supply units, depending on the charging state of the battery.
Apart from this, the LCD Battery Computer S provides the display of the battery voltage (V) of a second battery (starter
battery). Due to its various display functions, it allows a centralized supervision of the consumers as well as of the most
important processes at the battery at any time. So, it allows quick reactions to undesirable developments or to take
corrective measures in good time.
The precision measuring shunt for detection of the battery current being provided with the unit is extraordinary robust, very
exactly and shows extreme overload capacity (also refer to "Technical Data").
The dimensions of the unit are perfectly 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 display, voltmeter, 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. If possible, the display should always be installed at eye-level in
the living area to ensure ease of operation and good visibility. The display can also be inclined to ensure best legibility. 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.
The delivered control cable of 5 m length is used to connect the display unit to the delivered current measuring shunt. The
connection is executed ready to be plugged in, and the cable should be laid according to the safety instructions.
The length of the control cable is 5 m. If this length is not sufficient for connection of the connection unit, the cable
extension of 5 m length, order No. 2005, being available as accessory can be used. The total cable length is then 10 m.
Measuring Shunt
Any battery current should flow over the measuring shunt. Therefore, it is to be installed directly near the battery
(batteries). Observe that all consumers and charging devices for the battery must be led over the shunt in order to allow a
registration of any battery activity. Battery systems are to be connected according to the plan.
