The control panel consists of display screen 1 with the function keys described below. The
display 1 consists of a two-row alphanumerical LCD display with 16 symbols per row. The
function keys 2 are located below and to the right of the display screen. The status of the
function keys and the machine operating modes are shown with LEDs in the corresponding
keys. Every time the function keys 2 are operated, a key tone sounds as confirmation of the

input. If the input required is invalid, e.g. because the max. permissible value for the
parameter input has been reached, a double tone is audible. An SD-card reader for data
transfer is integrated.
7.04.01 Screen displays
Depending on the operating mode, on the screen 1 information is shown about the machine
status, program selection, sequence program progress, input parameters, as well as error signals (also see Chapter 11 Input).
Depending on the operating mode, relevant data is displayed in combination with the ap-
●
propriate symbol or text, and can be altered directly.
When the parameters are entered, the number of the parameter selected is shown with
●
the corresponding parameter value, see Chapter 11.03 Parameter input.
If faults occur in the sewing operation, a corresponding error signal appears in the display,

8 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.
8.01 Installation
The site where the machine is installed must be provided with suitable connections for the
electric current, see Chapter 3 Specifications.
It must also be ensured that the standing surface of the machine site is firm and horizontal,
and that sufficient lighting is provided.
For packing and transportation reasons the table top is in the lowered position.
The table height is adjusted as described below.
Installation and commissioning
If the machine is delivered with stand, the transit lock must be removed before
commissioning, see Chapter 8.01.02 Removing the transit lock.
