9. Remove the instrument from the lower tool and verify the green led turns ON.
Warning :
The missed turning-ON of green led could indicate the need of a
mechanical adjustement intervention. Call the press manufacturer or the
personnel charged by him. Do not make attempts not described on this
manual or on the manual of the press.
Verification of the correct positioning
Execute the following procedure:
•
Set and activate the operating mode 2, in such a way that the front part is in blanking
and the rear part is excluded.
•
Put the part of the instrument of cylindric shape against the lower part of the punch, in
such a way that only this part intercepts the central detection field of the device (keep
the fingers outside the area).
•
Make the instrument slide along all the upper tool, verifying the continue interception
of the field by means of the continue turn-ON of the RED LED and the turn-OFF of the
GREEN LED on RX.
•
Now, put the part of the instrument with thickness of 10 mm over the lower tool and
command the press in fast closing keeping outside of the die area. To make the test
meaningful, the speed change point must be set as nearest as possible to the die. For
the same reasons, set, on the Numeric Control, the minimum thickness possible for
the sheet or, alternatively, interpone a sheet with thickness equal to the set one
between die and test piece.
•
Verify that the mobile table stops with a distance between the tools greater than or
equal to 15 mm, because the part of the instrument with this thickness must be able to
pass between the dies.
•
Repeat the operation for 5 times, placing the test piece on the left side of the press
near TX and other 5 times with the test piece placed on the right side near RX.
•
At last, place the part of the tool with 35 mm thickness over the lower tool and
command the fast closing of the moveable table, staying outside the dangerous area.
•
Verify the press stops and the upper tool does not touch the instrument.
•
Repeat this test with the same modalities of the test above (5 more 5 times).
The adjustment of the device must be considered correct only if all the indicated tests are
passed. Ohterwise, the press must not be absolutely used.
