FRONTAL KEYBOARD DESCRIPTION
ø
YELLOW
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.
INPUTS / OUTPUTS DESCRIPTION
DC POWER
(input 1-2) 24V DC Power Supply of the instrument.
AC POWER
(input 3-4) AC Power Supply of the instrument; it can be to 24 - 110 - 230 VAC according to demand.
24 VDC - 80mA
(input 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.
DISPLAY DESCRIPTION
-----
When the device is switched on and when there are no impulses in its input, the device
visualize 5 horizontal bars.
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

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

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)

t.r. = Reset time of the display.
This parameter allows to program the maximum time from the last impulse after that the
instrument reset the display, showing the four horizontal bars. If programmed = 0, with no
impulses in input the instrument shows the last calculated value. If the programmed time is
lower than the time between the impulses, the instrument shows the four horizontal bars.
This parameter is useful to indicate when a plant is in stop or when there are no
impulses in input or when the impulses source is damaged. It’s programmable
between 1 (instantaneous) and 99 seconds.
̼ Ç1
t.d. = Updating time of the display.
This parameter allows to program the delay time of the data adjournment on the
display. It’s programmable between 0 (instantaneous) and 9,9 sec
1æ F

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.
rËon
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
¼È 5
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 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 the fourth display from right; visualization 9,999
d.p. = 5 Floating Point.
¹È È
¹È ê
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.
