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.
INPUTS / OUTPUTS DESCRIPTION
AC POWER SUPPLY
(inputs 5-6)
AC Power Supply Input of the instrument; it can be to 24 - 110 - 230 VAC in according to demand.
DC POWER SUPPLY
(inputs 7-8)
DC Power Supply Input of the instrument; input 8 (-), input 7 (+).
24 VDC - 80mA
(inputs 9-10)
24 VDC - 80 mA auxiliary Power Supply that the instrument supply to feed the Encoder and proximity amplified.
INPUT
(input 11)
Input of count adapted for electromechanical and logical contacts, encoder and 3 wires proximity amplified, configurable in Positive
(PNP) and Negative (NPN) logic.
RESET
(input 12)
Input of RESET that executes the reset of the visualized count showed on display at the moment of its activation.
INHIBIT
(input 13)
Input of count inhibition: when activated it blocks the count of the normal counter and the totalizer.

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

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.

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.

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

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.

A.P. = 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.
Toì
99999
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.
