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 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.

SET POINT PROGRAMMING
For SET POINT programming access, proceed as follow:
- Press key ‘PRG’ in impulsive mode; on display appears:
Ë1 <
S.1 = SET POINT 1, main Set Point, programmable between 1 cent and 9999h59m
(depending to the selected scale). 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:
Cod
0000
GROUP 1

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

Ìê9²9
t.r. = Time of Automatic Reset, programmable from 0.0 to 99.9 sec. This parameter allows to
make to work the instrument in automatic mode. When the timing arrives to the value of S.1, it
automatically resets the count, excites the RL1 relay and it resumes to count. The RL1 relay
remains excited for the set up time 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 bigger than the time employed to the timing to arrive
to the values of S.1, the relay will never come unactived.
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 = 99m59s99c - 2 = 99h59m59s - 3 = 9999h59m - 4 = 9999s99c
Cæ UP

Cæ SÈ
Count UP / DOWN / Superior.
Count = Up: Up; the timer gets ready to visualize the timing in increasing way (UP), starting
from zero up to the programmed value of set point. To the end of timing it works in Manual or
Automatic mode, as programmed in t.r. function.
Count = dn: Down; the timer gets ready to visualize the timing in decreasing way (DOWN),
starting from the programmed value of set point to zero. To the end of timing it works in
Manual or Automatic mode, as programmed in t.r. function.
Count = Sp: Superior; the timer gets ready to visualize the timing in increasing way (UP),
starting from zero up to the programmed value of set point. To the end of timing it works in
Manual mode and the timing goes on up to a new command (START, RESET, INHIBIT).

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.

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.

Programming of the Automatic Reset Mode
This parameter allows to activate the timing to the beginning or the end of the programmed
time of the Automatic Reset
.
Auto I. = Activation of the timing to the beginning of the Automatic Reset Time
Auto F. = Activation of the timing to the end of the Automatic Reset Time

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.

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.
