DESCRIPTION OF THE FRONTAL KEYBOARD

ø

WHITE

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

WHITE

The key 'UP ARROW' in normal operating phase it enter and exit to the Totalizer.

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

DC POWER SUPPLY

(inputs 7 - 8) 24VDC Power Supply Input of the instrument.

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.

24 VDC - 80mA

(inputs 9 - 10) 24 VDC - 80 mA auxiliary Power Supply that the instrument supply to feed the Encoder and amplified

proximity.

START

(input 11) START Input that execute the timing starting as the programming mode; it’s configurable in Positive

(PNP) or Negative (NPN) logic by the dip switches on the rear.

RESET

(input 12) RESET Input that execute the timing reset; it’s configurable in Positive (PNP) or Negative (NPN) logic

by the dip switches on the rear.

INHIBIT

(input 13) INHIBIT Input that execute the timing Inhibit; it’s configurable in Positive (PNP) or Negative (NPN) logic

by the dip switches on the rear.

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:

SCÄ 1

SCL. = Time Scale. Selection of the maximum time scale of the timing. It’s possible to choose

between 4 different time scales:

1 = 9m59s99c - 2 = 9h59m59s - 3 = 999h59m - 4 = 999s99c

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.

RreË 0

reË 3

Function of RESET Key ; this programming enable and disable the RESET function of the

RES frontal key during the normal timing:

RES. 0 = RESET function of the RES key disabled

RES. 1 = RESET function of the principal timing only

RES. 2 = RESET function of the global timing only

RES. 3 = RESET function of the principal and global timings

Programming of the START Input.

This programming allows to Start the timing in three different modes:

In. I. = Impulsive Mode; the timing starts with the impulsive closing of the START input.

In. C. = Continuously Mode; the timing starts with the closing of the START input; the timing

is interrupted every time the START input comes opened.

In. S. = Start/Stop Mode; the timing starts with the impulsive closing of the START input and it

stops to the subsequent closing. Closing another time the input the timing resume and it stops

to the subsequent closing.

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 time will be visualized for 5 sec.

Toì

¨0¨00

The totalizer visualizes the total time that the instrument has show.

It can be resetted through frontal key RES or from RESET input when it is visualized on the

display.
