SET POINTS PROGRAMMING
For SET POINTS 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 0 and 99999999. 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:
GROUP 1
:
in order to approach the parameters of group 1, insert code
2357
and press
ENT
6 digits multiplier , programmable from 0,1 to 9.9999.This parameter allows to convert the
number of the input impulses, showing them on the display in an other format. If it programmed
= 0 it comes reprogrammed automatically to 1. If a value lower than 1 is inserted, it obtains the
division of the impulses. Es. I want to divide for 25 the impulses in input; calculation 1 : 25 =
0.04.
Attention: the variation of the value of the multiplying modifies automatically the value of the
count and the totalizer.
2 digits multiplier, programmable from 1 to 99.This parameter allows to convert the number
of the input impulses, showing them on the display in an other format. If it programmed = 0 it
comes reprogrammed automatically to 1.
Attention: the variation of the value of the multiplying modifies automatically the value of the
count and the totalizer.
t.r. = Automatic Time of Reset, programmable from 0.0 to 99.9 sec. This parameter allows to
make to work the instrument in automatic mode. When the count arrives to the value of S.1, it
automatically resets the count, excites the RL1 relay and it resumes to count without to lose
the impulses. The RL1 relay remains excited for the time set up 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 smaller of the time employed from the count to arrive
to the values of S.1 or S.2, the relative relays will not never come unactived.
Input Fast - Slow.
This programming allows to predispose the input of count to read signals coming from
electromechanical contacts (relay, switches etc.) that introduces false signals, or from logical
signals like proximity, encoder, transistor etc.)
In = F. predisposes the instrument in order to read to logical signals up to 15 KHz.
In = S. predisposes the instrument in order to read to electromechanical contacts up to 30 Hz.
Count UP / DOWN / Superior.
Count = Up: the counter gets ready to visualize the count in increasing way (UP), starting
from zero up to the programmed value of set point. To ended count it behave in Manual or
Automatic mode like programmed in t.r.
Count = dn: the counter gets ready to visualize the count in decreasing way (DOWN), starting
from the programmed value of set point to zero. To ended count it behave in Manual or
Automatic mode like programmed in t.r.
Count = Sp: the counter gets ready to visualize the count in increasing way, starting from
zero up to the programmed value of set point. To the attainment of the value of programmed
set point it behave as in the Manual count and continues to count the impulses in input.
