7.04 Keyboard on machine head (only on the PFAFF 2595 and 2596 PLUS)
The machine has a keyboard with●8keys to activate different functions.
In the keys●2– 7there are yellow LEDs. These shine when the respective function has
been allocated to key 1.
Green LEDs are located above the keys●2- 7. These shine when the function has been
activated.
Above key●1there are two symbol lamps.
Lamp Aindicates the status of the bobbin thread control.
Lamp Bshines when the minimum level of the oil supply has been reached.
When the keys●1– 8are operated, the functions listed below are carried out.
Key 1: The functions of the keys 2- 7can be allocated to this key.
To program key 1, simultaneously press one of the keys 2- 7and key 1for approx.
3seconds.The function of the selected key is taken over and the yellow LED in this
key lights up
Key 2: Reverse sewing or intermediate backtacks during the seam.
Under Parameter 634 other functions can be assigned to this key:
Set value ON = Feed adjustment when machine has stopped and when
machine is running (standard)
OFF = Feed adjustment only when machine is running

Key 3: Needle position change
Under Parameter 695 other functions can be assigned to this key:
Set value 0 = Off
1 = needle raised without trimming
2 = needle position change (standard)
3 = single stitch
4 = single stitch in reverse
5 = moving forwards to needle position step by step
6 = programmable tack on / off
Key 4: Calling up the pre-selected top feed lift.
(Diode on = high lift, diode off = low lift).
Under Parameter 401 other functions can be assigned to this key:
Set value 0 = Off
1 = when key pressed constant second stroke (standard)
2 = second stroke only as long as key pressed
If this key is operated, the second voltage is switched on
This function can be switched off under Parameter 764
Key 5: Bartack suppression for one bartack
Under Parameter 780 other functions can be assigned to this key:
Set value 0 = Off
1 = tack inversion once (standard)
2 = tack suppression (all tacks switched off)
3 = reverse move to needle position step by step
4 = edge trimmer on / off
5 = programmable tack on / off
Key 6: Calling up the pre-set stitch length
Diode on = large stitch length, diode off = small stitch length.
This function can be switched off under Parameter 786.
Key 7: If this key is operated, the second thread tension is switched on.
If this key is pressed for longer than about 2seconds, the machine moves to the
threading position - the needle is raised and the motor start inhibitor is activated
(sewing threads are not trimmed).
If the key is operated again, the motor start inhibitor is deactivated again
Key 8: EMERGENCY KEY.
Needle is raised without trimming, the thread clamp is opened, the thread
tension is released, the presser foot raised and the motor start inhibitor activated
(diode above the key lights up red)..
If the "scroll" key on the control panel is pressed, the motor start inhibitor is
deactivated again.
The method for setting parameters is described in the settings manual, and
may only be carried out by certified professionals!
