Principle of operation of INC/DEC commands

2 The KTF/PW4 power supply has an analogue exclusion input (
connectable to the machine inverter input (e.g. on MATEC machines).
The analogue exclusion input allows to exclude the MULTIFEEDER devices
when the machine drops under a determined number of revs/min, i.e. when it
is in the stop phase.
The KTF/PW4 power supply comes with the analogue input already calibrated
for correct operation; however you can change the triggering point of
MULTIFEEDER exclusion, by adjusting the trimmer (T).
3
Connect the 24VAC supply terminals to the output of TRF24 transformer.
4
Connect the terminal to the machine ground potential.
5
Connect the STOP output of both KTF/PW4 groups to the machine STOP
input.
6
Connect (+ INC) and (+ DEC) terminals to the thread guide common positive
or solenoid valves of the machine.
7
Connect (- INC ) and (- DEC) terminals to a pair of thread guide
programmable outputs or solenoid valves, or use the outputs provided by
BTSR for MULTIFEEDER devices.
Activate the programmable INC/DEC outputs simultaneously with the thread
guide of yarn under control and keep the commands active for all the yarn
processing time, then deactivate the programmable INC/DEC outputs
simultaneously with the thread guide of yarn.

When, on the contrary, the INC/DEC commands are deactivated, the
MULTIFEEDER device operates with the tension value set in

To gradually adjust the value of tension set in
once the INC/DEC command have been activated, you will have to generate INC
(increment) or DEC (decrement) pulses.
For each INC or DEC pulse, the
