3.2 Setting the top puller pressure
The pressure of the top puller can be set when the puller feed drive is ac-
tivated.
Fig. 3: Setting the top puller pressure
1. Activate the puller feed drive.
2. Pull the adjustment knob (1) up.
3. Turn the adjustment knob and set the pressure (0 - 6 bar):
•clockwise: to increase pressure
•counterclockwise: to reduce pressure
4. Push the adjustment knob (1) down.

4.1 Setting the feed distance
The feed distance can be set between a length of 1 – 15 mm per stitch in
increments of 1/10.
1. Tochangethefeeddistanceofthetoppuller,pressthePlus/Minus (D)
buttons.
2. To change the feed distance of the bottom puller, press the Plus/
Minus (B) buttons.
4.2 Setting the puller feed type
Two types of feed are available: Constant or intermittent feed. With inter-
mittent feed, the speed is restricted and depends on the feed distance set.
1. Open the parameter t 14 11.
2. Set the feed height:
• 0: constant
• 1: intermittent
Information
To change quickly between the feed types, the puller feed type can be pro-
grammed to the freely programmable F-key on the control panel (parame-
ter t 52 20 = 23).

4.3 Setting the puller feed operating mode
You can set when the puller should lift up automatically.
1. Open the parameter t 14 00.
2. Set the operating mode:
• 0: Puller is not lifted up
• 1: Puller is lifted up with sewing foot aeration
• 2: Puller is lifted with bar
• 3: Puller is lifted with sewing foot aeration and bar
4.4 Setting the puller delay
You can set the number of stitches until the puller is lowered.
1. Open the parameter t 14 03.
2. Set the number of stitches (0-255).
The puller feed button lights up, the puller feed drive is activated.
4.5 Setting the angle of feed
You can set the angle at which the puller is to feed.
0° is the reference position here.
The default settings are:
• 10° for the initial feed angle
• 170° for the final feed angle
1. Open the parameter t 14 12.
2. Set the initial feed angle (0-359°).
3. Open the parameter t 14 13.
4. Set the final feed angle (0-359°).
4.6 Setting the material compensation values
Slip properties of various materials can be compensated for.
1. Set a stitch length of 5 mm.
2. Open the parameter t 14 21.
3. Set the material compensation value for the top feed puller (0-255).
4. Open the parameter t 14 31.
5. Setthematerialcompensationvalueforthebottomfeedpuller(0-255).

5 Service
5.1 Initializing the puller feed drive
The puller feed drive has been preset in the factory. It may however be
necessary to reinitialize the puller feed drive e. g. in case of a software up-
date.
1. Open the parameter t 51 25.
2. Select function module C = 10.
3. Confirm with OK.
The parameter t 11 60 opens up.
4. Select function 5.
5. Opten the parameter t 51 53.
6. Select function module 23.
7. Open the parameter t 14 10.
8. Set the number of pullers = 2.
The puller feed has been initialized.
5.2 Setting other parameters
5.2.1 Setting the transmission ratios
The transmission ratios of the stepper motors can be set to the relevant
drive shafts. A transmission ratio of 1000 i.e. a 1:1 ratio has been preset
in the factory.
1. Open the parameter t 14 20.
2. Set the puller feed upper transmission ratio (1-9999).
3. Open the parameter t 14 30.
4. Set the puller feed lower transmission ratio (1-9999).
5.2.2 Setting the puller feed pressure
1. Open the parameter t 14 14.
2. Set the feed pressure:
• 0: In case rapid stroke adjustment, the puller remains lowered with
hydraulic pressure
• 1: In case of rapid stroke adjustment, the puller is relieved of pneu-
matic pressure. The pressure of the springs only acts on the mate-
rial
• 2: Permanently depressurized

5.2.3 Setting puller feed operation
1. Open the parameter t 14 10.
2. Set the puller feed operation
• 0: No puller feed
• 1: Puller feed with one puller only from above
• 2: Puller feed with one puller each, from above and below
5.3 Malfunctions
Description Possible cause Remedy
Both feed pullers feeding in
the wrong direction The wires of the stepper motors have got mixed up. • Swap over the wire connec- tions.
Stepper motors not moving • Wires connected incor-
rectly
• Puller feed drive not cor-
rectly initialized
• Check the wires.
• Check the settings.
