Remove the instrument from the lower tool.
Move RX in vertical direction in such a way that the LOWER EMISSION HORIZONTAL
SURFACE coincides with the LINE FOR RX VERTICAL POSITIONING as in Fig. 15.2.
Check that the YELLOW/BLUE LED of RX turns on to confirm the executed alignment.
Warning :
If the yellow LED does not turn on, a mechanical adjustment
intervention could be necessary. Call the manufacturer of the press
or the personnel charged by him. Do not act on the collimation
screws because the receiver could be wrongly adjusted.
15.4. Check of the correct positioning
Check the correct positioning of TX and RX with respect to the punch by means of the test
and positioning instrument.
Set and activate the operating mode 2 in such a way that the front part is in blanking and
the rear one is excluded.
Lay the cylindrical part of the instrument against the lower part of the punch in such a way
that only this part intercepts the central detection field of the device (e.g., keep the fingers
outside the area). Then move the instrument along all the upper tool checking the continue
interception of the field through the steady turn-on of the RED LED and the switch-off of the
GREEN LED on RX.
Now lay the instrument part with thickness equal to 10 mm over the lower tool and
command the fast closing of the press, standing outside the area of the dies.
In order to make the test meaningful, the speed change point must be set as close as
possible to the die. For the same reasons, the minimum thickness possible of the sheet
must be set on the Numeric Control or, in alternative, a sheet with thickness equal to that
set must be put between the die and the test item.
The mobile table must stop and the clearance between the tools must be 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 5 times placing the test item on the left side of the press-brake near
TX and other 5 times with the test item placed on the right side near RX.
At last, place the part of the instrument with thickness equal to 35 mm over the lower tool
and command the fast closing of the mobile table standing outside the dangerous area. The
press must stop and the upper tool must not touch the instrument.
Repeat this test with the same modalities of the test above (5 plus 5 times).
The adjustment of the device must be considered correct only if all the specified tests are
passed. Otherwise the press-brake must not be absolutely used.
15.5. Check of the Receiver LEDs
Once energized, executed the check of the stop space (if RX is equipped with it) and
correctly adjusted the device, in absence of interception of the detection area we must
obtain the contemporary turn-on of the YELLOW-BLUE and the GREEN LEDs. Moreover,
the BLUE LEDs, pointing out the selection of the operating mode 1, must be on.
The interception of the detection area must cause the turn-on of the RED LED and the turn-
off of the YELLOW/BLUE and GREEN LEDs.
Warning :
If one of the LEDs was faulted, stop immediately the machine and
call NUOVA ELETTRONICA to repair the device.
