Fitting

The thread sensor must be fitted so that the threads or wires are touching the
eyelets continuously. The movement will be best detected, if the thread or wire
deviates about 10–15° when it passes through the thread sensor eyelet. A thread
guide can be fitted to ensure this deviation.

Connection

* If connection is made via

screw terminal, the lid
must first be opened. See
instructions on next side.

The signal amplification
"Gain" is set with a
potentiometer in the
central control unit.
Please refer to the
instruction for the
central control unit you
are using.

Central control

When two or more SMG thread sensors are used,
they will be connected in parallel.

How to open and close the lid

Reaction time (Drop-out time)

Depending on type, speed, tension, etc of the detected thread or wire, the signal
from the eyelet can be irregular and cause false stops. The false stops can be
avoided by increasing the reaction time. When it is important that the stop occurs
very quickly after a thread or wire failure, it is necessary to decrease the reaction
time.

To set the reaction
time:

Open the lid.

Locate the 2 x 9 pole
pin strip with the con­nection shunt.

Set the shunt in the
desired position.

Some SMG thread sensors are
equipped with a master switch. With
this switch the entire thread sensor can
be switched off. A green LED beside
the master switch is on, when the
thread sensor is switched on (active).
