2.3 Setting the remaining thread monitor electrically

Important

The remaining thread monitor is delivered with a basic setting.
As a rule, the sensitivity of the residual thread monitor does NOT have
to be set!
The pre-set sensitivity of the remaining thread monitor may only be
changed if the remaining thread monitor is not working properly.

Fig. 9: Setting the remaining thread monitor electrically

(1) - Plug connection light barrier,

right hook

(2) - Plug connection light barrier,

left hook

(3) - Plug connection inputs and outputs

of the control

(4) - Plug connection switched output
(5) - Potentiometer left hook
(6) - LED
(7) - Potentiometer right hook
(8) - Plug connection auxiliary output

After the machine has been switched on and before it starts sewing, the
remaining thread monitor is in setting mode.

To set the remaining thread monitor:

1. Switch on the machine.

2. Insert an empty bobbin into the hook.

3. Turn the hook to a position that the light beam falls through the slot in

the hook housing onto the bobbin.

4. Set the potentiometer (5) or (7) to the highest sensitivity.

To do this, turn the potentiometer clockwise.

Assembling the remaining thread monitor

5. Turn the hook until the light beam hits the reflective surface on the

bobbin.

 The LED (6) lights up for 1 second with each reflection in the setting

mode.
The output to the control and the auxiliary output are switched on.

6. Turn potentiometer (5) or (7) counterclockwise to reduce the sensitivity

until the reflection can just be detected.

When sewing begins, the system leaves setting mode automatically.
