Procedure to perform a cut in “MANUAL CUT” mode

Press the button on the screen , from now on a series of pages will guide the oprrator to set the machine:

Press on the button MANUAL

The machine is provided with the STOP CUT function: therefore you can program until 2 intermediate stops during the slab cut.

The two stop values can be set in STOP 1 and STOP 2.

NB. You cannot set a value of STOP 1 higher than the value of STOP 2.

To deactivate one of the two values you can set the value to 0.

NB. The STOP values can be modified even when the automatic cycle is running. A window will ask if you want to perform the required modification.

You can enable or deactivate this function by operating on the specific video selector:

: function deactivated

: function enabled

The stop cut modes are described in the OPERATOR SETUP section in the specific manual.

Press the button to go on or the button to go back to the previous page.

Press the button to go back to the main page or the button to go back to the previous page.

1	Make sure that the machine is not in the alarm state and that it is in the MANUAL state signalled by icon: .
2	Move in manual the Drop and Carriage axes to the start point of the cut you want to perform.
3	Activate input I18 – CYCLE START, through the button located on the front side of the panel below the terminal, to set the machine in the AUTOMATIC OFF state, signalled by icon .
4	Start the flywheel motor by pressing the key F1 The activation of the motor is signalled first by the flashing of the LED F1 and then, once the star/delta exchange has occurred, by the fixed switching on. At the same time the LED F2 activates as well, indicating the activation of the water electro-valve exit.
5	Start the cut in Manual Cut mode by pressing the key F5 The activation of the work cycle is signalled by the activation of the LED F5.

In the Manual Cut procedure the platform starts from the value where it is and goes up until value 0 (bench edge) with a speed which is regulated by the potentiometer located on the front side of the operator panel.

Once the value 0 has been reached the main motor switches off and the blade remains stationary at the reached value.

Procedure to perform a cut in “AUTOMATIC CUT” mode

Press the button on the screen , from now on a series of pages will guide the operator to set the machine:

Press on the button AUTOMATIC

This page sets the entry speed of the blade into the material to be cut during the automatic cut.

You can set 5 different heights (ENTRY 1, ENTRY 2, ENTRY 3, ENTRY 4, ENTRY 5) during the entry phase of the blade into the block and associate a different drop speed to each of them.

• Entries [cm] : INCREMENTAL value during which the drop speed set in Speed [cm/h] is activated

• Speed [cm/h] : drop speed of the Blade axis used for the associated height.

• AUTOMATIC WORK : at the end of the space used for the entry of the blade into the block, the remainder of the lowering uses the speed that was set in this parameter.

• EXIT : Space of cutting end.

Example: You want to set a pre-set Quota of 100 and three Heights of 10 (with speed A), 20 (with speed B) and 30 (with speed C). Moreover the Automatic Work is set at speed D and an exit 5 with speed E.

When the automatic cycle starts the machine will perform the first 10 cm at speed A, the second 20 cm at speed B and the next 30 cm at speed C. The other 35 cm (100 – Entry 1 – Entry 2 – Entry 3 – EXIT) will be performed at speed D.

The last 5 will be performed at speed E. At the end of the lowering the blade moves up again with maximum speed.

NB. You can enter a Height equal to 0 but you cannot associate a null Speed to a Height.

NB. The ENTRIES and the SPEEDS can be modified even when the automatic cycle is running.

Press the button to go on or the button to go back to the previous page.

To work with the automatic speeds, it is required to set the starting value from which the device will start calculating the values of the various entries.

Therefore take the block below the blades and press the button to load the value in the program.

If the work cycle has been deactivated, the device calls the operator's attention on the fundamental operation of blade value self-learning:

If the operator presses the key YES, he informs the device that the self-learning has been performed, therefore the device goes back to the main page.

If he presses the key NO, that means the operation was forgotten. Therefore the device displays the Value Setting page again.

This request is not made if the automatic cycle is active.

1	Make sure that the machine is not in the alarm state and that it is in the MANUAL state signalled by icon: .
2	Move in manual the Drop and Carriage axes to the start point of the cut you want to perform.
