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
RED
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 <
9999
99
S.1 = SET POINT 1, main Set Point, programmable between 0 and 99999999. If programmed
= 0 the Set Point remains excluded and the instrument works like a totalizer and predisposing
the count in UP mode.
Key ENT confirms the data. 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:

in order to approach the parameters of group 1, insert code

©0000
6 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 for 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 an 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.
Ìê9²9
t.r. = Automatic Time of 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 time set up 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 smaller of the time employed from the count to arrive
to the values of S.1 or S.2, the relative relays will not never come unactived.
1æ F

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

Cæ SÈ
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.

Active or excluded memory.
This parameter allows to program the saving of the current counter value during the power off
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.
RreËon

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 counter
and the totalizer.
RES.on = RESET function of key RES enabled
RES.of. = RESET function of key RES disabled

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 999999
d.p. = 1 Decimal Point on the second display from right; visualization 99999,9
d.p. = 2 Decimal Point on the third party display from right; visualization 9999,99
d.p. = 3 Decimal Point on the quarter display from right; visualization 999,999
d.p. = 4 Decimal Point on fifth display from right; visualization 99,9999
d.p. = 5 Decimal Point on sixth display from right; visualization 9,99999
Attention, the Decimal Point is only fictitious, it doesn't realize any conversion.
0í1 î
0í1 ÷
Programming of the OUTPUT 1 RL1. This parameter allows to activate the RL1relay to the
beginning _ I or to the end I_ of the count.
Ou.1 î = the Activation of the RL1 relay to end of count
Ou.1 ÷ = the Activation of the RL1 relay to beginning of count
¹È È

Activation mode of the programmed parameters.
With this programming is possible to activate the executed programmings directly to the exit of
the programming or, when exited of the programming, after a RESET (with frontal key or from
rear input)
A.P. = P. Activation of the parameters to the exit of the programming.
A.P. = r. Activation of the parameters to the exit of the programming after a RESET.
Pressing the key ù the totalizer of impulses will be visualized for 5 sec.

The totalizer visualizes all the impulses that the instrument counts from its input IN1.
It can be resetted through frontal key RES only or from RESET input when it is visualized on
the display.
