FRONTAL KEYBOARD DESCRIPTION

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.

INPUT / OUTPUT DESCRIPTION

DC POWER

(inputs 1-2) 24V DC Power Supply of the instrument.

AC POWER

(inputs 1-2) AC Power Supply of the instrument; it can be to 24 - 110 - 230 VAC according to demand.

24 VDC - 100mA

(inputs 5 - 6) 24 VDC - 80 mA auxiliary Power Supply that the instrument supply to feed the Encoder and amplified

proximity.

INPUT

(input 7) Input of count adapted for electromechanical and logical contacts, encoder and 3 wires proximity

amplified, configurable in Positive (PNP) and Negative (NPN) logic by the dip switches on the rear.

RESET

(input 8) Input of RESET that executes the reset visualized count showed on display at the moment of its

activation.

INHIBIT

(input 9) 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:

Cod

GROUP 1

:

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

2357

and press

ENT

Æ1 “

©0000

6 digits multiplier, programmable from 0,1 to 9.99999.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.

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 25 Hz.

NeÆon

NeÆoF

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

reËoF

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

¼È O

¼È 5

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.

¹È È

¹È ê

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

999999

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.
