DESCRIPTION OF THE FRONTAL KEYBOARD
ø
YELLOW
The key 'LEFT ARROW' in normal operating phase visualizes, blinking, all the programmings executed without the
limitation of the insertion code. The time of scansion of the programmings is given from the pressure of the same
key. It exits automatically from this phase after 5 sec of the last pressure of the same key.
In programming phase it moves the cursor of the figure towards left of a step, than at the beginning it is on the right
side first one on the. At the end it resumes from the first one to right.
ù
YELLOW
The key 'UP ARROW' in normal operating phase visualizes the totalizer of impulses.
In programming phase it increases the value of the blinking figure.
ú
BLUE
The key 'PRG' pressed for 2 sec. allows to enter in the programming phase, visualizing on display C.0000.
In the programming phase, pressing key 'PRG' impulsively, it exits from the programming phase. The instrument exits
automatically from the programming phase, 60 sec. after the pressure of the last key.
û
GREEN
The key 'ENT/RES' in normal phase of counting has the 'RESET' function, with the modalities to it attributed in the
programming phase.
In programming phase it confirms and memorizes the visualized data and passes to the successive function. If it has
arrived to list end it resumes from the beginning.

SET POINTS PROGRAMMING
For SET POINTS programming access, proceed as follow:
- Press key ‘PRG’ in impulsive mode; on display appears:
Ë1 <
99999
S.1 = SET POINT 1, main Set Point, programmable between 0 and 99999. If programmed = 0
the Set Point is excluded and the instrument works like a totalizer and predisposes the count in
UP mode.
Ë2 <
99999
S.2 = SET POINT 2, Point, programmable between 0 and 99999. If it programmed with value
higher or same to S1 it comes reprogrammed like S2 = S.1 - 1.
Key ENT confirms the data and passes to the successive programming. In order to exit the programming, press key PRG.
PROGRAMMING OF THE OPERATION PARAMETERS
The programmable parameters are divided in two groups and protect with a 4 figures code.
In order to approach the programming, proceed in the following way:
- Press key PRG for about 2 sec. On the display appears:

5 digits multiplier , programmable from 0,1 to 9,9999.This parameter allows to convert the
number of the input impulses, showing them on the display in an other format. If it programmed
= 0 it comes reprogrammed automatically to 1. If a value lower than 1 is inserted, it obtains the
division of the impulses. Es. I want to divide by 25 the impulses in input; calculation 1 : 25 =
0.04.
Attention: the variation of the value of the multiplying modifies automatically the value of the
count and the totalizer.
Æ2 10
2 digits multiplier, programmable from 1 to 99.This parameter allows to convert the number
of the input impulses, showing them on the display in other format. If it programmed = 0 it
comes reprogrammed automatically to 1.
Attention: the variation of the value of the multiplying modifies automatically the value of the
count and the totalizer.

t.r. = Time of Automatic Reset, programmable from 0.0 to 99.9 sec. This parameter allows to
make to work the instrument in automatic mode. When the count arrives to the value of S.1, it
automatically resets the count, excites the RL1 relay and it resumes to count without to lose
the impulses. The RL1 relay remains excited for the set up time in t.r. If the time of reset is
programmed = 0 (0.0) the instrument gets ready to works in manual mode.
Particular cases: if the set up time t.r. is bigger than the time employed to the count to arrive
to the values of S.1, the relay will never come unactived.

Input Fast - Slow.
This programming allows to predispose the input of count to read signals coming from
electromechanical contacts (relays, switches etc.) that introduces false signals, or from logical
signals like proximity, encoder, transistor etc.)
In = F. predisposes the instrument in order to read logical signals up to 15 KHz.
In = S. predisposes the instrument in order to read electromechanical contacts up to 30 Hz.

Count UP / DOWN / Superior.
Count = Up: the counter gets ready to visualize the count in increasing way (UP), starting
from zero up to the programmed value of set point. To ended count it behave in Manual or
Automatic mode like programmed in t.r.
Count = dn: the counter gets ready to visualize the count in decreasing way (DOWN), starting
from the programmed value of set point to zero. To ended count it behave in Manual or
Automatic mode like programmed in t.r.
Count = Sp: the counter gets ready to visualize the count in increasing way, starting from
zero up to the programmed value of set point. To the attainment of the value of programmed
set point it behave as in the Manual count and continues to count the impulses in input.

MEM. = Active or excluded memory.
This parameter allows to program the saving of the current counter value during the power off
of the instrument.
MEM.on. = memorization of the count during the power OFF. When power ON the instrument,
the display will visualize the last present value in the power OFF phase.
MEM.of. = excluded memorization of the count; every time that the instrument comes powered
OFF and then powered ON the count comes lost and the instrument restart always from the
initial condition.

RES. = RESET Key ON / OFF; this programming enables and disables the RESET function of
frontal key RES during the operation of the counter. The disabling does not allow to reset the

S2 programming in Absolute or Offset mode.
This programming allows uses of S.2 set point in ABSOLUTE or OFFSET value regarding S.1.
S.2 = AS. Programming of S.2 in ABSOLUTE value. The programmed value is the real value
to which it will active the set point S.2 in UP and SP mode. In dn. mode S.2 will active as
impulses before zero as has been programmed. Example of operation in UP and SP. mode
with S1 = 100 and S.2 = 80: the set point S.2 will be active at 80 and S.1. at 100. In DOWN
(dn.) mode, S.2 will be active at 20 (80 impulses before 0) and S.1 = 0.
S.2 = of. Programming of S.2 in OFFSET regarding S.1. With this programming the real value
of S.2 is legacy to the value of S.1. The value of S.2 is obtained from the difference of S.1 and
S.2. In UP and SP. mode, S.2 will be active as impulses before S.1 as has been programmed.
In DOWN (dn.) mode the S.2 set point will be active as impulses before zero as has been
programmed. Es. of operation in UP and SP mode. S1 = 100 and S.2 = 80: the S.2 set pioint
will be active to 20 (80 impulses before S.1) and S.1. to 100. In DOWN (dn.) mode S.2 will be
active to 80 (80 impulses before 0) and S.1 to zero. Changing to the value of S.1, automatically
the absolute value of S.2 changes.

d.P. = Programming of the Decimal Point of the Counter and the Totalizer.
This programming allows to add a decimal point to the visualization on the 5 digits, in order to
obtain counts with various resolutions.
d.p. = 0 Decimal Point excluded; visualization 99999
d.p. = 1 Decimal Point on the second display from right; visualization 9999,9
d.p. = 2 Decimal Point on the third party display from right; visualization 999,99
d.p. = 3 Decimal Point on the fourth display from right; visualization 99,999
d.p. = 4 Decimal Point on fifth display from right; visualization 9,9999
Attention, the Decimal Point is fictitious only, it doesn't realize any conversion.
