The control panel consists of display 1 and the function keys described below. The display 1 consists of a single-line alpha-numerical, 7 segment LCD display with 8 symbols. The texts 2, located above and next to the LCD display, show the respective status of the function keys and the operating status of the machine. The control panels switches on all
LCD-segments and the horn automatically for a short time during the power-on phase, after which the lettering PFAFF appears on the display, until the higher-ranking control unit sends commands to the control panel.
The function keys are located around the display 1. They are foil-packed without permanent marking and without contact signal. Fixed functions are allocated to the keys, see Chapter
7.10.02 Function keys.
Screen displays
●
Activated functions are displayed with a triangular marking 3 below or next to the respective function key.
●
In the sewing mode all relevant sewing data is displayed and can be changed directly, depending on the status of the machine, see also Chapter 10 Sewing.
●
During the parameter input the selected parameter number with the corresponding value is displayed, see Chapter 12.08.02 Example of a parameter input.
Function keys
The function keys described below are used basically to switch machine functions on and off.
Each time a key is pressed, this must be confirmed by at least one beep tone. Irrespective of the machine mode a double beep signal is given if invalid keys are pressed or maximum values reached.
If a corresponding value has to be set for the activated function, this is carried out with the corresponding +/- key. By pressing and holding the corresponding +/- key, the relevant numerical value 4 is changed slowly to begin with. If the corresponding +/- key is held down longer, the values change more quickly.

Controls
Start backtacks
●
If this key is pressed, the backtacks at the beginning of the seam (start backtacks) are switched on or off. The number of forward stitches (A) or reverse stitches (B) for the start backtacks can be changed by pressing the +/- key underneath. To convert from double backtack to single backtack set the number of stitches for the corresponding seam section at zero.
End backtacks
●
If this key is pressed, the backtacks at the end of the seam (end backtacks) are switched on or off. The number of reverse stitches (C) or forward stitches (D) can be changed by pressing the +/- key underneath. To convert from double backtack to single backtack set the number of stitches for the corresponding seam section at zero.
Needle position
●
If this key is pressed the "needle raised after sewing stop" function is switched on or off.
When the function is switched on, the needle positions at t.d.c. after sewing stops.
Foot position after stop
●
If this key is pressed the "foot raised after sewing stop" function is switched on or off.
When the function is switched on, the presser foot is raised after sewing stops.
Foot position after trimming
●
If this key is pressed the "foot raised after thread trimming" function is switched on or off.
When the function is switched on, the presser foot is raised after thread trimming.
Thread trimmer
●
If this key is pressed the thread trimming function is switched on or off.
Darning program
●
If this key is pressed the darning program function is switched on or off. The counted seam function is switched off automatically.
Counted seam
●
If this key is pressed the counted seam function is switched on or off. The darning program function is switched off automatically.
TE/Speed
●
If this key is pressed once the speed limit for the sewing mode is activated.
●
If this key is pressed twice (within 5 seconds) the machine changes from sewing to input mode.

Installation and commissioning
The machine must only be installed and commissioned by qualified personnel!
All relevant safety regulations must be strictly adhered to!
If the machine is delivered without a table, be sure to use a stand and table top that can hold the weight of the machine with its motor.
It is very important to ensure that the stand of the machine is firm and steady, also during sewing.
Installation
The site where the machine is installed must be provided with suitable connections for electric current.
It must be ensured that the standing surface of the machine site is firm and horizontal, and that sufficient lighting is provided for.
For packing and transportation reasons the table top is in the lowered position.
The table height is adjusted as described below.

Commissioning
Before commissioning the machine, clean it thoroughly, fill the oil pan with oil and adjust the oil level, see Chapter 10 Care and Maintenance!
●
Examine the machine, in particular the electric cables, for any damage.
Have qualified personnel check whether the machine can be operated with the available voltage and whether it is connected properly. If there are any irregularities do not operate the machine!
The machine may only be connected to an earthed socket!
When commissioning the machine or after a long period of non-operation, operate the machine with max. 2000 spm for the first 10 minutes! Danger of damage to the machine!
●
When the machine is running, the balance wheel must turn towards the operator. If this is not the case, have the motor adjusted by qualified personnel, see the motor operating instructions.

●
Switch the machine on as described in Chapter 7.01 Main switch.
When the machine is switched on for the first time, the text "pulley" appears on the display pulley
●
Operate the pedal briefly (sewing).
The machines begins to run slowly, ascertains the transmission ratio between motor and machine and stops running after about 2 revolutions.
If the pulley function does not appear after the machine has been switched on for the first time, or if the machine has an undefined position, a master reset must be carried out, see Chapter 12.10 Cold start in the adjustment manual.

During all cleaning work the machine must be disconnected from the power supply by switching off the main switch or pulling out the plug!
Danger of injury if the machine is started accidentally!
Cleaning the machine
The cleaning cycle required for the machine depends on following factors:
●
Single or several shift operation
●
Amount of dust resulting from the workpiece
It is therefore only possible to stipulate the best possible cleaning instructions for each individual case.
For all cleaning work the machine must be disconnected from the mains by switching off the on/off switch or by removing the mains plug!
Danger of injury if the machine suddenly starts up .
To avoid breakdowns, the following cleaning work is recommended for single shift operation:
●
Clean hook compartment and needle area of sewing head several times daily.
●
Clean the entire machine at least once a week.
