Step 3 :
The machine has stopped and the limitswitch V.S.A. is engaged yet (open contact). The test
is passed, the machine can start the working cycles.
OR
The press has stopped but the limit-switch V.S.A. has become free. The test is not passed.
The two OSSD will permanently remain in state OFF. At this point, it is not possible to
command at high speed any more, but the power supply must be switched off in order to
repeat the test after having check and, possibly, removed the causes of the test failure.
10.1.5. Interlock of restart
While the machine is stopped and an object is detected by DSP LASER, because it
obscures one or more receiving elements, the device sets the OSSD outputs to OFF state.
When the object is not detected any more, the outputs return to ON state.
If the detection of the object takes place with machine in closing, then with the signal
pointing out PEDAL in ON state (Press brake closing pedal (IN PD)), the device sets, even
in this case, the outputs to OFF state.
However, when the object will not be detected any more, in order the outputs can return to
ON state, the PEDAL (Press brake closing pedal (IN PD)) must be released and then the
relevant signal must be in OFF state. Until when this condition is not realized, the outputs
will remain in OFF state. When the PEDAL signal is present in ON state, it is necessary that
even the HIGH SPEED signal is present (High speed in press brake closing (IN AV)),
otherwise a condition of OFF state of the outputs occurs.
