Operation Principle Of Smart Matrix Quilt And Prx Signal Management - btsr SMART MATRIX QUILT Operating Manual

Operation Principle of SMART MATRIX QUILT and PRX Signal
Management.
The SMART MATRIX QUILT System allows you to control the yarn tension during the stitching operation,
using as reference two different sets of parameters which reflect the status of your quilting machine
EXT = machine running at low speed or at the initial ramp stage;
speed, or at normal speed after the initial ramp stage).
The actual control, however, is carried out only while the system receives the PRX signal (i.e. during the
actual operation of the stitching needles).
At system installation time, you must then pay particular attention to the following points:
1) Make sure that your machine is capable of providing a signal related to the needle activation and
connect such signal to the PRX EXT signal of the SM-DIN QUILT Board.
2) Check whether your machine is capable of providing two distinct signals related to the operating
status (low/high/speed) of the machine itself. If this is the case, then connect the two signals to the
SLOW EXT and
3) Is your machine does not provide two distinct signals (SLOW/FAST), but it can provide in any case
a "Start" signal, this can be connected to both inputs

If you set Tol = 4, then the alarm will be activated only when the error condition (tension lower or
higher than the established threshold) persists for at least 4 consecutive PRX pulses.
