5.14.5
Comments or hidden text
Everything that is written on the line after the semicolon is ignored by the CN. Therefore, lines that are
not to be executed may be “hidden” by entering the symbol “ ; ” before the line or adding comments to
improve code comprehension.
5.14.6
Operating sequence in automatic mode (AUTO)
When the master is executed for the first time (first cycle), the axis go to the initial position (safety
position) and the machine waits for the operator to block the piece and close the door. The repeated
sequence will be:
Stand-by for left hand blocking
Stand-by for left door to be closed
[execution left programme]
Left piece unblocked and loading door opened
Stand-by for right hand blocking
Stand-by for right door to be closed
[execution right programme]
Right piece unblocked and loading door opened
When the door is closed, the blocking pressure increases from 2 to 6 bar for safety reasons.
Furthermore, low pressure may be adjusted by means of two pressure regulators (right and left) located
in the pneumatic box.
Note: When the loading door is closed, the blocking/unblocking pedal is disabled.
To use vacuum blocking, just turn on the vacuum pump (using the respective pushbuttons on the
operator panel) and follow the same blocking procedure with the presses. The vacuometer located near
the loader will show the operator if the operation has been successful (or not)
.
5.14.7
Operating sequence in manual mode (MANUAL)
In manual mode, the loading doors may be opened and closed by pressing the black pushbutton
(“DOOR” or “START”) located beside the doors. The piece may be blocked and unblocked (at low
pressure) by using the special pedal, only if the door is open.
As in automatic mode, the blocking pressure increases from about 2 bar (low pressure) to 6 bar when
the doors are closed.
NOTE
Safety
warning
DANGER!
Danger of flying pieces or tool parts.
The vacuum pumps may be turned off only when the blocking systems on both
benches are in the unblocking stage.
