Installation and Operating Manual
LED Tank Display HE 010
12 V / 24 V, Measuring Signal 0-10 V
No. 0242
The VOTRONIC LED
Tank Display HE
is a special development for
heavy-duty use in fire fighting vehicles
,
and it serves
for exact remote indication of the level of water and foam tanks.
The tank level is represented by means of 10 super bright light-emitting diodes in form of a
tricolour luminous band
(red/yellow/green). Intermediate level values are indicated by a change of the luminous intensity of the respective
highest light-emitting diode. The representation of the display is an almost
continuous luminous bar
.
A photocell
controls
the
brightness
of the
light-emitting diodes of the display in such a way, that it can be
read
exactly,
even in case of direct sunlight or darkness.
The design of the robust display unit is very compact,
it is sealed water-tightly and dust-tightly, it is completely
vibration-proof,
and it is suitable for installation in display panels. It is designed for an operating voltage of 12 V to
24 V, and it is rated and factory-adjusted to a standard measuring signal from 0-10 V (e. g. for VOTRONIC
Tank Sensors
FW
120
or
FW 240).
The unit is equipped with an efficient protection against wrong polarization and overvoltage.
A simple parallel connection of the desired number of
LED Tank Displays HE
allows
control of the tank from several
locations of the vehicle
.
Installation:
The LED Tank Display is designed for installation in display panels.
Opening rectangular, width 38 mm, height 56 mm, mounting depth max. 27 mm.
Fastening on the display panel can be effected by screwing the delivered fastening screws into the mounting holes of
the LED Tank Display.
Connection Plan:
Start-up and Adjustment:
After supply of the operating voltage and connection to a tank sensor, the tank level will be indicated by means of the
light-emitting diodes.
The display unit has been factory-adjusted, so adjustment tasks are not required.
