Function of mea ure of the ab orbed yarn (LFA)
This function counts the meters of yarns furnished by the feeders in a turn of the machine. The number shown in
the specia page is updated every 5 turns of the machine and the maximum shown number is 99 meters and 99
centimeters. The '*' that appears in the disp ay points out that the corresponding magnetic sensor is active.
The too reads up to 5 feeders of which the first 4 are suitab e for feeders type MPF20 or MPF10 or MPF-L; the
ast visua ized feeder 'P5' is predisposed for the feeder 'MER-2' or 'MER-3' used for the Lycra se ectab e by the
dip-switch 4 ocated inside the instrument case:
•set 'OFF' the dip-switch 4 to configure the feeder input P5 for type MER-2
•set 'ON' the dip-switch 4 to configure the feeder input P5 for type MER-3
At power-on the processor read the dip switch configuration and show on disp ay the writing 'L2' if configured for
MER-2 type, or otherwise show 'L3' if configured for MER-3 type.
You can choose among two ways to see the quantity of absorbed yarns:
1) in the c assica visua ization the disp ay show absorbed meters and centimeters for a turn of the oom , where
the maximum shown number is 9999 centimeters which is 99 meters and 99 centimeters.
When this visua ization is used, near to the number there is a 'Cm' or 'In' to point out the unity of measure, it
depends on the choice of use centimeters or inches.
2) in the so-ca ed 'advanced visua ization' or 'for 100 need es' it is showed the yarns absorbed for 100 need es ,
where the maximum shown number is 9990 centimeters or 99 meters and 90 centimeters. The shown number
often contains a decima , for instance 7,5 centimeters for 100 need es.
When this visua ization is used, c ose to the number there are 'Cm/K' or 'In/K' based on the unity of measure
choose between centimeters or inches. In other words, the measured consumption is divided by the hundreds of
need es and then shown on the disp ay.
To choose between c assica visua ization or “for 100 need es” there is a specia page ca ed 'Need es Number '
used to write/point out the number of need es present in the machine. Such number of 4 digits can be zero, in such
case the c assica visua ization is used. If instead such number is among 100 and 9999 the page 'LFA' show the
“for 100 need es” or advanced visua ization.
A number of need es sma er then 100 is considered as 0.
A a rule of thumb the device i ent with a number of needle equal to zero o it u e the cla ical
vi ualization.
The instrument can memorize the measured va ue as a reference va ue , and then check that the consumption
doesn't change too much from such reference va ue; the va ue of reference and the a owed to erance can be
p anned through the specia pages re ative to the LFA function.
Reference and To erance contro is enab ed at the fo owings conditions:
•P anned to erance is greater of 0%; note that there is a specific to erance for each trace from P1 to P5.
•In the initia page to erance has been enab ed pressing for a ong time the key ; in this case there is the
symbo '%.
•The va ue of reference is different from '0.'
The contro of the to erance is performed on the average of 5 turns and it attends some turns to the starting.
