Preliminary Instructions for the Correct Use of IS3W.. Sensors
After having completed the installation of the whole system, it is necessary to
proceed with the initial setup of the system itself. To do this, operate as follows.
1)
Check all the electrical connections (see chapter 2).
2)
Supply the system and check that all the IS3W.. devices haw the red led on.
3)
Number the IS3W devices
(SETUP DEVICE CONFIG).
4)
Configure the parameters related to the machine characteristics, sensor
detection characteristics and sensor operating modes (
CONFIG MENU
)
.
5)
Create an article with the desired measurement/control parameters
(NEW)
6)
Load the created article (
LOAD
) and check, using the GRAPH function, that
the system properly performs the meter count feature and signals the error
condition in case of yarn breakage/missing (
if the BK function is enabled
)
LDRUM Setup Procedure
The following is a suggested procedure to setup the LDRUM parameter for an
individual machine position; However it is convenient to carry out the same
procedure simultaneously on more positions in order to obtain an average value.
1)
Program the desired sensor with a LDRUM value equal to 1000; in this way
the sensor will increment the counter by 1 unit upon each stroke.
2)
Program the TARGET value of the sensor with a very large number, in order to
prevent the sensor from stopping the machine because of TARGET reached.
3)
Reset the sensor’s stroke counter using the “Touch Light” and confirm that the
counter is actually set to zero, by reading the value on

terminal
(GRAPH function)
.
4)
Weigh each cone and take note of the values; we will call these measurements:
T
1
, T
2
,… T
N
.
5)
Produce one or more bobbins with the desired diameter.
6)
For each bobbin produced, read the sensor’s counter value; we will call these
measurement
CNT
1
, CNT
2
, … CNT
N
7)
Weigh the bobbins produced using a precision scale; we will call these
measurement
M
1
, M
2
, … M
N
8)
Obtain the weight of yarn using the following formula; we will call the
obtained values
P
1
, P
2
, … P
N
P
i =
M
i -
T
i
9)
Through the values
P
1
, P
2
, … P
N
and knowing the type and title of the yarn, it
is possible to calculate the number of meters collected on the bobbin. We will
call these values
Meters_Weight
1
, Meters_Weight
2
, Meters_Weight
N
10)
Using the following formula we will obtain the value to be set as LDRUM:
LDRUM
i
=
1000* Meters-Weight
