SICK nanoScan3

When the internal restart interlock is used, the following sequence is the result for the
mac
hine operator:
1 A safety output of the safety laser scanner switches to the OFF state, if there is an
interruption in the protective field.
2 The safety output remains in the OFF state when there is no longer an object in
the protective field.
3 The safety output only switches back to the ON state when the operator presses
the reset pushbutton, which is outside the hazardous area. If there is an object in
the protective field when the reset pushbutton is pressed, the safety output stays
in the OFF state.
4 After the reset, the operator can restart the machine in a second step.
