If from the principal screen you push S6 (LAV), you will enter into WORK, where it is possible to insert different variables, in function of the need:Pieces number that you want to carry out; possibility to insert or not the control of the step in half-auto (for the first positioning of the material under the mould), possibility to insert or not the open roll in half-auto (the open roll is always controlled by the cam), possibility to insert or not the memorised open roll (the open roll in this case follows the cam, but it is the operator that chooses when it has to open, through a proper button; it is particularly useful when there are step moulds where the pilot is insert after a certain number of steps), possibility to insert or not the lubrication with axis movement (the band is oiled for all step long), possibility to insert or not the step & impulse lubrication ( here you have the possibility to set up the step thet you want to oil and also the oiling duration).

The advance of the actuators exit, if inserted, allows the actuators exit as soon as the feeder receives the START, if not inserted it allows the actuators exit only when the material has reached the memorised position.

All the functions over described are referred to the working program.

In the Program list please select the desired program and push S6 (LOAD).

After the program loading you can go ahead with the work; please insert the AUTO selector and push ON. The line will start in automatic.
