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 2
:
in order to approach the parameters of GROUP 2, insert code

and press
ENT
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.
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
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.
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 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.
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.
