With the setting of "INP1" and "DSP1", the instrument should be able to operate correctly. Notwithstand, depending on the system
characteristics, it may be necessary to modify the internal measurement times.
A
fter programming the "DSP1" parameter with decimal point, a push of
ENTER
of approx. 3s provides access to set the numerical
values of sam
p
lin
g
and limit times.
SAMPLING TIME (TIME)
With irregular input signals, the display may present fluttering
or unwanted variations due that the number of input cycles
detected at each reading are not equal.
The "TIME" parameter allows stretching the measurement
interval while making an average of the readings taken along
the programmed time. This reduces possible display jittering.
T
he sampling time is programmable from 0.0 to 9.9 seconds.
A
value of 0.0 means that no average will be made. It is set
at the factory to 1 second.
T
o help stabilizing the display in case of irregular input
signals it is recommended to increment this parameter, taking
into account that the display readout will be update at the
programmed time.
The sampling time can be reduced, if the input signal is
stable at the operating frequency, to increment the displa
y
update rate.
LIMIT TIME (LIM)
The limit time, programmable from 1 to 10 seconds, is
applied in order to limitate the waiting time for at least 1
pulse is produced at the input before considering it to be
zero.
T
he limit time is initialized at the reception of each inpu
t
pulse. If no pulse is detected before completion of the
programmed time, the display goes to zero.
T
he instrument is shipped from the factory with a limit time
of 10 seconds.
Decreasing the limit time makes the instrument be able to
respond more quickly to the zero condition when the system
stops but this reduction leads to an increment of the
minimum displayable reading before the display goes to zero.
For example suppose that the desired readout for an inpu
t
frequency of 1KHz is 1000 lit/s.
With a limit time of 10s, the minimum frequency is 0.1Hz and
the display readout at this frequency is 0.1 lit/s. Since this
value would not be readable in a display of 1000 counts, the
limit time could be reduced to 1s, so the minimum frequenc
y
will be 1Hz and the minimum readout before displaying zero
will be 1 lit/s.

The first menu parameter allows selection between two display modes.
T
he direct mode must be selected when the display readout and the input frequenc
y
are to be in a direct proportion, that is, the display goes high as the frequency grows.
T
he reverse mode should be selected when reading variables that are inversel
y
proportional to the input frequency.
Press to change the previously selected option if desired (dir = direct mode,
inv = reverse mode) and press
ENTER
to validate the choice and advance to the nex
t
programming phase.
T
he indication shown in figure 18.3 is viewed for 2s before passing to the inpu
t
frequency programming phase. After 2s or by a press of
ENTER
, the display shows an
y
numerical value (depending on previous setting) with the first digit in flash.
If desired to modify this value, press to vary the flashing digit from 0 to 9, and
the key to advance to the next digit to be modified. Repeat these operations
until the display reads the required value and press
ENTER
to save the entry in the
memory; the decimal point goes in flash. Press repeatedly the key to move the
decimal point to the desired position if required.
Press
ENTER
to save changes and go to the next programming phase.
From the Pro stage (see fig. 15.1), press

PULSES PER REVOLUTION (PPR)
T
he “PPr" parameter is the number of pulses given by a
complete revolution of the sensor connected to the
instrument’s input.. It is programmable from 1 to 9999.
RESOLUTION (DCP)
T
he "dCP" parameter allows setting the display resolution to
units (without decimal point) or to tenths (with one decimal
place).
EXAMPLE
It is desired to display the rate of a turning shaft that delivers
50 pulses per each revolution.
A
s the only necessary parameter, the "PPr" (pulses pe
r
revolution) must be programmed to 50. The "dCP" parameter
should be set to the desired resolution according to the max.
reading.
With the setting of "PPr" and "dCP" the instrument should be
able to operate correctly, notwithstand, depending on sensor
characteristics, it may be necessary to adjust the internal
sampling and limit times.
A
fter programming "dCP", a push of “ENTER” of 3s gives
access to program these parameters.
SAMPLING TIME (TIME)
With irregular input signals, the display may present fluttering
or unwanted variations due that the number of input cycles
detected at each reading are not equal.
The "TIME" parameter allows stretching the measuremen
t
interval while making an average of the readings taken along
the programmed time. This reduces possible display jittering.
T
he sampling time is programmable from 0.0 to 9.9 seconds.
A
value of 0.0 means that no average will be made. It is set at
the factory to 1 second.
LIMIT TIME (LIM)
T
he limit time, programmable from 1 to 10 seconds, is applied
in order to limitate the waiting time for at least 1 pulse is
produced at the input before considering it to be zero.
The limit time is initialized at the reception of each input pulse.
If no pulse is detected before completion of the programmed
time, the display goes to zero.
T
he instrument is shipped from the factory with a limit time o
f
10 seconds.
Decreasing the limit time makes the instrument be able to
respond more quickly to the zero condition when the system
stops but this reduction leads to an increment of the minimum
displayable reading before the display goes to zero.

goes to the normal operating mode.
How to interpret the programming instructions
The programming software routine is composed by a series of hierarchically organized menus, each allowing the setting of a
specific parameter. In general, the normal sequence at each step is to push the key a number of times to make changes
and the
ENTER
key to store them in the memory and advance to the next step.
The elements used along the programming instructions are described following.
T
he programming instructions for each menu step are accompanied by a figure
representing the display indication for the corresponding parameter. Pay special
attention to the LED indications and active keys and follow the procedure described on
the text to introduce correctly the desired data.
When the display indication is represented with blank segments, it means that this is
one of the possible options of this menu (normally the default one) depending on the
previous selection.

T
he enclosed diagram shows the
complete programming routines
for models µD-TAC.
a) The basic parameters, which
refer to the input and displa
y
configuration are organized into
two modules: "InP" and "dSP".
b) If a 2-relay option is installed
(see page 27), the module "Set",
that allows configuring the option,
is automatically included in the
routines.
c) If a 2-relay option is installed,
the setpoint values programming
is directly entered from the Pro
stage.

t the end of each module, the
indication Stor appears while data
is saved in the memory.

To configure the input to the indicator, set the switch SW1 as indicated in the table

CCESS TO THE PROGRAMMING MODE

The display configuration depends on the input type selected in the input module.
 As RATE METER, the display module includes programming of the input frequency with decimal point and the desired displa
y
with decimal point. The display/frequency ratio may be set for direct or reverse operation.
 As RPM METER, the only parameter necessary to configure the display is the number of pulses per revolution that delivers
the sensor. Programming is completed with the display resolution.
T
o adjust the display to the particular system characteristics, the display module includes the parameters sampling time and limit
time, which are accessible by holding the “ENTER” key for 3 seconds before exiting from the program routines.
INPUT FREQUENCY (INP1)
T
he "INP1" parameter refers to the input frequency generated
by the transducer. This frequency must be within the specified
limits (0.1Hz to 7KHz) and can be programmed with two, one
or no decimal places.
DESIRED DISPLAY (DSP1)
T
he "DSP1" parameter is the desired display readou
t
corresponding to the frequncy programmed in the “INP
”
phase. The decimal point can be located in any of the digits o
f
the display.
T
he display variation can be directly proportional to the inpu
t
variation (increasing frequency →increasing display) or
inversely proportional (increasing frequency →decreasing
display and vice-versa).
T
he first menu step allows to select one of these modes (dir =
direct, inv = reverse).

EXAMPLE
It is desired to measure the rate in m/s of a conveyor belt
which is driven by a turning shaft of 20 cms diameter and
300 rpm that gives 4 pulses per revolutiion.
In 1 second, the shaft gives 20 pulses (300 rpm = 5
revolutions per second and 1 revolution = 4 pulses). The
input frequency is then 20Hz. At such frequency, the rate o
f
the conveyor belt is :
rpm ×π×d = 300 ×π×20 = 18849.6 cm/min = 3.142 m/s
The INP1 and DSP1 parameters must be : INP1 = 20, DSP1
= 3.142.
T
he display mode must be selected for direct variation with
respect to the input frequency (dIr option).
