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
ConnBoard
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.
ConnStart
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.
ConnBoard
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.
