8.05.01 Functions of the switches and buttons
Switch 1
is for changing between the RPM and number-of-buttonholes readings in the display.
When this switch is up, the RPM reading is displayed. The RPM can be altered using
buttons T3 ( + ) and T4 ( - ).
When this switch is down, the number of buttonholes sewn is displayed. The maximum
number which can be displayed is 65536.
By holding button T4 pressed and pressing T2 briefly this counter can be reset to zero.
To do so the buttons must be held for approx. 1 second.
Switch 2
Is for setting the countdown mechanism.
When the switch is up, the following reading appears in the display:
XXX YYY
XXX = the total number of buttonholes to be sewn.
YYY = the number of buttonholes still to be sewn.
By pressing button T2, the YYY reading ( buttonholes remaining ) is made to equal the XXX
reading (total buttonholes).
The range for the total number of buttonholes lies between 0 and 500.
A start is only possible when switch 2 is down ( off ).
In normal operation, a renewed start of the machine is impossible when the number of
buttonholes remaining is 0 ( YYY = 000 ). The fault reading BOBBIN appears in the display.
After changing the bobbin, this disturbance can be removed by pressing button T2.
This returns the number of buttons remaining ( YYY ) to the same level as the number of
buttons to be sewn ( XXX ).

Switch 3
serves to start and stop winding the bobbin.
When the switch is up, winding can take place as long as the foot pedal is pressed and one
cycle is not yet completed.
Switch 4
switches between work cycles.
When the switch is up the machine carries out only one cycle.
When the switch is down the machine carries out two cycles.
8.05.02 Switching the countdown device on/off
When the machine is switched on, the countdown mechanism (parameter 620) can be
switched on and off by the operating personnel as follows:
● Press buttons T1 and T4 simultaneously.
● Press button T2.
● Press button T3 or T4.
I = countdown ON
II = countdown OFF
● Press buttons T1 and T4 simultaneously.

After the fault reading BASIC, the machine runs with the reduction speed in its starting
position after being restarted with the pedal.
The fault reading BOBBIN can be anulled by pressing button T2 or machine ON / OFF.
All other fault readings can only be anulled with the machine ON / OFF switch.
Q-faults
Q-faults are motor specific faults. The following readings can appear in the display of the
quick control panel:
Q2 = No impulses from position transmitter or impulses from position transmitter
not recognized.
Q10 = Commutation plug not inserted.
If other Q-faults are displayed, the motor control box should be changed.
It is also possible that these fault readings can be caused by cable breakages. This should
be checked.
By pressing button T2 the work clamp can be raised or lowered when the
machine is in basic position.

9 Mounting and initial operation
This machine may only be mounted and put into operation by qualified
specialists! All relevant safety regulations are to be adhered to!
9.01 Mounting
Connections for electrical and compressed air supplies must be available at the machine’s
location ( see chapter 3 Specifications ).
A solid, horizontal surface and adequate lighting must also be guaranteed.
Due to reasons of packaging, the table top is lowered on machines with
stands. When putting the machine into operation, the table top should be
raised again or adjusted to an ergonomically suitable height.
The PFAFF 3117 is available in two mountings.

● Check the machine for any possible damage, especially the electrical and pneumatic
leads.
● Clean the machine thoroughly and then oil it ( see chapter 13 Maintenance and care ).
● Connect the machine to the power supply.
● Connect the machine to the compressed air supply. The manometer should display an air
pressure level of approx. 6 bar. Adjust to this value if necessary ( see chapter 13.03

Preparation
11 Preparation
All regulations and notes in this Instruction manual are to be adhered to.
Special attention is to be taken to the safety requirements!
All Preparation work must be carried out only by appropriately trained persons.
The machine is to be separated from the power supply at the On/Off switch or
by pulling the plug out of the socket whenever carrying out preparation work!
11.01 Inserting the needle
Switch off the machine!
● Loosen the needle retaining screw 1.
● Insert needle 2 as far as possible.
● The long needle-groove must be facing
the knife.
● Tighten the needle retaining screw 1.
Attention! needle point and
knife blade! Danger of injury!
Hole 3 can be used to check if
the needle 2 is inserted
properly. By inserting a suitable
tool into hole 3 pieces of
broken needle can be
removed.

● Place an empty bobbin 1 onto the bobbin shaft 2.
● Thread the machine in accordance with Fig. 11-02.
● Push key 3 to the end of the bobbin shaft 2.
● Regulate the thread tension by turning the milled screw 4.
● Push the foot pedal.
● The bobbin winder stops automatically when the bobbin 1 is full.
● Clamp the thread coming from the spool in the clamp 5 and snap the thread.
● For bobbin winding see section 8.05 Functions of the quick control panel
( switch 3 ).
If the thread winds unevenly:
● loosen nut 6.
● Turn the thread guide 7 accordingly.
● Tighten nut 6.

● Open tensioner 1 as far as possible.
● Adjust tensioner 2 so that the knots of
the stitches are in the middle of the
material.
● Adjust tensioner 1 so that the knots of
the purl stitches are pulled up.
Carry out this adjustment with
needle and bobbin threads of
different colours.

● Insert bobbin 1 into bobbin case 2.
● Pass the thread through slot 3 and under spring 4.
● Then pass the thread into slot 5.
● Pass the thread out of hole 6 again.
● Adjust the thread tension by turning screw 7.
● Use the enclosed tool for this process.
The bobbin thread should be able to be pulled easily and evenly out of the
bobbin case 2 for sewing purl buttonholes. Therefore, turn screw 7 so that the
bobbin case 2, with a full bobbin 1, slides slowly downwards when hanging
freely from the thread.

11.05 Adjusting the needle thread tension on flat buttonholes
and flat bartacks
● Adjust tensioners 1 and 2 ( less tension )
so that the knots in the stitches are
pulled onto the underside of the material.
Carry out this adjustment with
a needle thread and a bobbin
thread of different colours.
