8.1 Checking the basic control setting

Once the machine has been set up the basic control setting

should be checked and adjusted if necessary. In order to

change the basic setting the machine must switched on while

pressing the “F” key.

As soon as the green LED above the “F” key lights up

the key can be released: the LED flashes. On completion of the

internal system check the “special functions” selection is

displayed.

The various special functions are called by pressing keys 1 to 7;

the green LEDs above the keys indicate the function called.

The following sections describe special key functions 2, 4

and 5. The other special functions are described in the

Servicing instructions. Press the “F” key to leave special

functions and switch to normal operation: the LED above the

key goes out.

8.1.1 Setting the LED and display brightness

After calling special functions (see section 8.1), press the key 2.

All the LEDs are switched on. The brightness can be adjusted to

any of 8 levels by pressing the “+/-” keys. Press the “F” key twice

to save the brightness setting and switch to normal operation.

Brightness is factory-set to level “03”.

8.1.2 Moving to the reference position after each thread cut

When the machine is switched on the step motor that sets

the overfeed length moves to the reference position. In order to

check the position of the step motor more often, the step motor

can also be moved to the reference position after each thread

cut. The procedure is as follows:

–

After calling the special functions (see section 8.1)

press the 4 key.

–

The function can now be switched with the +/- keys:

–

display 00 = move to the reference position only when the

machine is switched on.

–

display 01 = move to the reference position after each thread

cut.

–

Press the “F” key twice to save the setting and terminate the

function.

The machine is factory-set to “00”.
