generatethedesiredsignal at the input signal termi-
nal, and operate the internal «Span» and «Offset»
potentiometers according to the indications below :
8.- CONFIGURINGTHEREADINGOFTHEINSTRUMENT___________________________________________
Example .- configure unit BDF-xx-32 for «4/20 mA»
inputsignaland«0/100.0»reading
a.- Unplug the instrument from the power supply
Unscrew the rear side cover to access the
«ControlBoard»andthe«InputModule»
b.- Select the «Input Signal» jumpers.
For«4/20mA»closejumpers«A»,«C»and«F»
c.- Select the jumpers for «Offset». The «Offset»
valueisthereadingfortheminimumsignalinput.
In this case «4mA = 0000» and the «Offset»
value is«0000»,closejumpers«P»and«M»
d.- Select the jumpers for «Span». The «Span»
value is the reading for maximum signal input
minus the reading for minimum signal input.
Inthiscase«4/20mA=0/1000»andthe«Span»
valueis«Span» = 1000 - 0000 =«1000».
Selectjumper«K»
e.- Connect a 4/20mA signal generator to the input
signal terminal. Plug the power supply, and leave
3minutesforwarm-up
f.- Generate 4mA
Operate the «Offset» potentiometer on the
«ControlBoard»untilreadingis«0000»
g.- Generate20mA
Operate on «PT1» («Span» potentiometer)at
the «Input Signal Module» until reading is
«1000»
h.- Repeattheadjustmentsat4mAand20mAuntilthe
readingsat«4mA=0000»and«20mA=1000»are
stable
i.- Select the decimal point at «XXX.X» position,
closing«JG»at the«ControlBoard»

13.-SECURITYPRESCRIPTIONS___________________________________________________________________
INSTALLATION PRECAUTIONS.- The installation
and operation of this instrument must be done by
qualifiedoperators.ThisinstrumentDOESNOThave
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
thepersonnel orthe processcan bedamaged, theappropriate security
elements must be added to the system in order to protect the operator
and / or the system.
SAFETY PRESCRIPTIONS.- This instrument has been
designed and verified according to the UNE-20553 rules and
is delivered in perfect conditions of operation. This manual
contains the adequate information 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 excesive heating, and far from
sources of electrical noise or magnetic field 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
finished. 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 excesive moisture.
DONOToperatetheunitinthepressenceofflammablegasesorfumes.
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 damages may result on both instruments.
POWER SUPPLY .- Connect the Power Supply to the terminals
indicated in this manual. Verify that the voltage and frecuency of the
power supply is according to the voltage and frecuency 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 sensors, 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 NOTinstallimpulse, controlor signalwirestogether inthe
same conduits as the wires connected to power lines,
connected to CC or AC engines, electromagnets, ...
b.-Whenusingshielded wires,connecttheshieldtothe 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...
INCASEOFFIRE
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 fire with carbonic snow, do not use
water in any case.
WARNING : In closed areas do not use systems with vapor-
ized liquids.
