Large displays for frequency signals (impulse / second)
The BDF series of large displays with ratemeter function
offer an indication proportional to the received frequency
signal, measured in impulses per second. The instrument
recognizes impulses from NPN and PNP sensors, Mechani-
cal Contacts, Encoders, and others.
The received «impulses per second» signal is multiplied by
internal «scale factors» and loaded on display, allowing to
display in engineering units (meters per minute, RPM, m3
/ hour), ... Position for the decimal point is programmable.
All instruments with 4 or 6 digits format, with digit height 57
or 100mm, in red color.
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 antir-
re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.

Programming the instrument
The BDF Ratemeter instruments are congured by program-
ming codes that activate internal «scale factors», decimal
points, and other elements which scale the signal reading
on display.
The programming of these codes is done through the 15 pin
SUB-D connector at the rear side of the instrument. A «KBD
Programming Keyboard» is needed, or the connections
shown in Figure 1 need to be set-up..
Buttons «1» to «6» introduce the numerical characters 1, 2,
3, 4, 5 and 6 on display, button «#» executes «ENTER» on
the displayed code. Button «*» adds negative sign in some
codes.
Note .- When KBD (or contacts indicated in Figure 1) are
connected to the BDF, the point placed on top of the negative
sign will light. This led must be «on» during the reprogram-
ming of the unit (if the led is not lightning, but the led below
the negative sign lights, then press «*» to switch leds).
Note .- When KBD (or contacts indicated in Figure 1) are
connected to the BDF Ratemeter with 4 digits, the 2 small 7
segment displays on top left part will light. These digits are
needed to programm some codes which are 6 digit codes.

Programming codes
The programming codes are made of 2 digits identifying the
code, and a third digit identifying the value assigned to the
code.
Code «41» with value «1» is represented as «41 1#». Button
«#» acts as a validation of the code and value entered. If this
button is not pressed, the unit will not validate the new value.
EXAMPLE
Introducing code «41 1#»
Press 4 Number 4 appears on display, to the left
Press 1 Number 1 appears on display, to the left
The current value for code 41 appears to
the right (it can be 1 or 2)
Press 2 Number 2 appears on display, to the right
replacing the previous value
Press # Validates the code and the value entered
(in this case 41 1)
Note .- After 6 seconds without introducing data, the instru-
ment will cancel the programming code without validation.
Note .- Codes «1», «2» and «3» are special codes composed
by only 1 digit. The value is a 6 digit numerical value and will
load on display as soon as the code is pressed. The way to
modify this value is to modify each digit value independently
by pressing 1 to 6 and then # to validate the whole.

Programming example
The default programming for the BDF Ratemeter units is 1 impulse/second = 1. If changing this relation is needed, then the
programming codes need to be accessed to change the scale factors of the unit. We take as an example the reprogram-
ming to 52 impulses/second = 247 meters/minute.
a.- The scale factors available and the values we can activate are the following :
«Scale Factor» selectable between -5.9999 and +5.9999
«Multiplication Factor» selectable at x1000, x100,x 10, x1, x0.1, x0.001
«Time Multiplication» selectable at x1, x60, x3600
b.- To generate a total scale factor of 4,75 (= 247 / 52) we can assign the following values
«Scale Factor» = 4,7500
«Multiplication Factor » = x1
«Time Multiplication» = x1
c.- The codes to program are
«3» 4,7500
«64 4#» x1
«62 1#» x1
Still, we need to program the Time Base which denes a «time window» where the unit will detect impulses, and will divide
the received impulses by the Time Base value, thus getting the frequency in impulses per second. The Time Base also de-
nes the refresh on display. By default, the Time Base of 0,5 to 1 second will be enough. In case the signal is too slow (0,1
impulses per second, for example) we would need a bigger Time Base. For 0,1 impulses per second we have 1 impulse
every 10 seconds. If we dene a Time Base of 1 second, the Ratemeter will always read «0000» because no impulse is
detected, and every once a while, 1 impulse will be detected.
d.- To program the same relation (52 impulses per second = 247.0 meters/minute), but with 1 decimal point, we need to
program the following:
«Scale Factor» = 4,7500
«Multiplication Factor» = x10
«Time Multiplication» = x1
«Decimal Point» = XXX.X
e.- The codes to program are
«3» 4,7500
«64 3#» x1
«62 1#» x1
«65 2#» Decimal Point on at XXX.X
The possible combinations of scale factors and decimal points are very big. Take into consideration that the decimal point
is only a led lightning, but it will not move the readings neither to the left nor to the right, and it will not multiply the reading
in any case. Start always dening parameter «3» which is the only one able to dene precise values, and then look for the
appropriate xed multiplication factors.
