Large displays for parallel BCD code
The BDF series of large displays for parallel BCD signal is
available in 4 and 6 digits format with 57mm or 100mm digit
height. Digits are 7 segments in red color (optional green led,
ask for information).
The display value of each digit is controlled by BCD code.
Several parallel lines control all digits (lines ABCD indepen-
dent for each digit). Control to light the decimal point indepen-
dent for each digit, control for «HOLD» function to block the
refresh of each digit, and control for negative sign (polarity)
Function «BLANK» to switch-off all segments and function
«TEST» to light all segments.
The mechanical of the BDF instruments is a very strong and
sturdy aluminium housing anodized in black color, for panel
mount, and for wall mount as an option. The front lens is
antirreexive and is rmly inserted on the aluminium prole
with a rubber gasket around, providing IP65 protection on
the front.
The signal wires are connected to plug-in screw clamps for
higher security of the connections, accessible at the rear side
of the instrument. The power is connected to a 3 terminal plug
(2 power connections and 1 earth) containing an integrated
protection fuse and an additional fuse as spare part.

Signal connections
Signal connections at male SUB-D connector available at
the rear of the instrument.
Each digit has 4 connection lines (ABCD) for its BCD code,
1 «Hold» line controlling the display update, and 1 control
for the decimal point.
The negative sign has 1 control line and 1 line for «Hold».
Connection lines identied as «+5Vdc» can be used as xed
controls with logical state «1».
Connection lines identied with «GND» can be used as xed
controls with logical state «0».
The «Digit 1» is the Least Signicant Digit.

damages may result on both instruments.
POWER SUPPLY .- Connect the Power Supply to the terminals indicated in
this manual. Verify that the voltage and frequency of the
power supply is according to the voltage and frequency
values indicated in the label attached to the unit. DO
NOT connect the instrument to power lines which are
overloaded, or power lines with loads working in ON/OFF cycles, or with
inductive loads.
SIGNAL WIRING .- Information to consider relating the wiring of the sen-
sors, probes, transducers, etc. The wires can act as antennas and introduce
electrical noise from the environment into the signal wires, specially if the
wires are close to noise sources or electromagnetic sources. There are
several rules generally known which should be taken into consideration
for the wiring :
a.- DO NOT install impulse, control or signal wires together in the same
conduits as the wires connected to power lines, connected to CC or AC
engines, electromagnets, ...
b.- When using shielded wires, connect the shield to the common of the
instrument, and leave not-connected the probe side
c.- The wires of impulse, control and signal should be placed in places
far away from switches, transformers, control relays, etc...
IN CASE OF FIRE
1.- Disconnect the unit from the power supply.
2.- Give the alarm according to the local rules.
3.- Switch off all the air conditioning devices.
4.- Attack the re with carbonic snow, do not use water
in any case.
WARNING : In closed areas do not use systems with vaporized liquids.
Warranty
All instruments are warranted against all manufacturing
defects for a period of 24 MONTHS from the shipment date.
This warranty does not apply in case of misuse, accident or
manipulation by non-authorized personnel. In case of mal-
function get in contact with your local provider to arrange for
repair. Within the warranty period and after examination by
the manufacturer, the unit will be repaired or substituted when
found to be defective. The scope of this warranty is limited to
the repair cost of the instrument, not being the manufacturer
eligible for responsibility on additional damages or costs.

INSTALLATION PRECAUTIONS.- The installation and
operation of this instrument must be done by qualied
operators. This instrument DOES NOT have power switch
and will start to operate as soon as the power supply is
connected. The instrument has an internal protection fuse, according to
IEC-127/2, and is located inside the power-supply connector. The values are
Fuse 200 mA Time Lag (for 230 Vac power)
Fuse 400 mA Time Lag (for 115 Vac power)
Fuse 350 mA Fast (for 24 Vdc power)
When the instrument is used to control machines or processes where the
personnel or the process can be damaged, the appropriate security ele-
ments must be added to the system in order to protect the operator and /
or the system.
SAFETY PRESCRIPTIONS.- This instrument has been designed and veri-
ed according to the UNE-20553 rules and is delivered in perfect
conditions of operation. This manual contains the adequate infor-
mation for the electrical installation. Before starting operations for
connections, readjustment, substitution, maintenance, repair, etc,
the instrument must be unplugged from the power supply. The instrument
must be installed in places with good ventilation to avoid excessive heating,
and far from sources of electrical noise or magnetic eld generators, such as
power relays, electrical motors, speed controls, etc... The instrument can not
be installed in open places. Do not use until the installation is nished. The
instrument is designed to be mounted on a metallic panel with the adequate
protections. DO NOT clean the front lens with abrasive products (such as
solvents, alcohol, etc) use a clean and water humid rag. Do not expose the
instrument to excessive moisture. DO NOT operate the unit in the presence
of ammable gases or fumes.
EXCITATION VOLTAGE Vexc.-
Instruments BDF-xx-32 and BDF-xx-36 supply an excitation voltage of 10 to
24 Vdc (50mA) to power transducers, available between terminals A and C.
Do NOT connect these terminals to an external power supply, permanent
