DESCRIPTION OF THE FRONTAL KEYBOARD

ø

WHITE

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

WHITE

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

WHITE

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.

configurable in Positive (PNP) and Negative (NPN) logic through PRI input (10).

INPUTS / OUTPUTS DESCRIPTION - Z SERIES

AC/DC POWER

SUPPLY

(inputs 2 - 10)

AC or DC Power Supply Input of the instrument; it can be to 24 - 110 - 230 VAC or 12 - 24 VDC in according to

demand.

24 VDC - 80mA

(inputs 7 - 8)

24 VDC - 80 mA auxiliary Power Supply that the instrument supply to feed the Encoder and proximity amplified.

PRI

(input 9)

Input used for the polarization of the count and command inputs : connecting the PRI output to input 8 it configures

the instrument in Negative logic (NPN), connecting the PRI output to input 7 it configures the instrument in Positive

logic (PNP).

INPUT

(input 5)

Input of count adapted for electromechanical and logical contacts, encoder and 3 wires proximity amplified,

configurable in Positive (PNP) and Negative (NPN) logic through PRI input (9).

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

000

GROUP 1

:

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

101

and press

ENT

¾Æ

0001

F.M. = 4 digits multiplier , programmable from 1 to 10000. This parameter allows to multiply

the number of the input impulses, showing them on the display in an other format. If it

programmed = 0 it means programmed 10000.

Attention: the variation of the value of the multiplying modifies automatically the value of the

count and the totalizer.

¾¼

0001

F.d. = 4 digits divisor , programmable from 1 to 10000. This parameter allows to divide the

number of the input impulses, showing them on the display in an other format. If it programmed

= 0 it means programmed 10000.

Attention: the variation of the value of the multiplying modifies automatically the value of the

count and the totalizer.

ºÌ

60

b.t. = Time Base.

This programming allows to select in which time base shows on the display the measure in

input. There are three scales:

1 = Time Base: seconds, measure visualization in seconds (ex. Meters/seconds)

60 = Time Base: minutes, measure visualization in minutes (ex. Liters/minutes)

3600 = Time Base: hours, measure visualization in hours (ex. Bottles/hour)

-----

When the device is switched on and when there are no impulses in its input, the device visualize 4

horizontal bars.

Pressing the key ù the totalizer of impulses will be visualized for 5 sec.

Toì

9

9999

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.

Input Fast - Slow.

This programming allows to set the count input to read signals coming from electromechanical

contacts (relays, switches etc.) or from logical signals like proximity switches transistor and

encoder.

In = F. sets the input to read digital signals up to 28 KHz.

In = S. sets the input to read electromechanical signals up to 25 Hz.

rËoí

Operation of the RESET Key; this programming enable and disable the RESET working of

the frontal RES key during the operation, as in the following modes:

RS.on. = executes the RESET of the visualized parameter

RS.oF. = RESET working of the RES key excluded.

¼È O

d.P. = Programming of the Decimal Point

This programming allows to add a decimal point to the visualization on the 4 digits, in order to

obtain counts with various resolutions.

d.p. = 0 Decimal Point excluded; visualization 9999

d.p. = 1 Decimal Point on the second display from right; visualization 999,9

d.p. = 2 Decimal Point on the third party display from right; visualization 99,99

d.p. = 3 Decimal Point on the fourth display from right; visualization 9,999

d.p. = 4 Floating Point.

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.
