SICK nanoScan3 I/O

Speed
•
R
ange: The monitoring case is activated if the speed is within the specified range.
You can use static control inputs as additional input conditions.
•
Limit: The monitoring case is activated via the static control inputs. The safety
laser scanner monitors the speed. If the speed is outside the specified range, the
safety laser scanner switches the safety outputs to the OFF state.
In this mode, the safety laser scanner ignores different speeds of the two incre‐
mental encoders for 60 seconds, even if the difference is greater than the config‐
ured tolerance.
7.12.5 Cut-off paths
Overview
Y
ou can create cut-off paths and define the outputs switched by the cut-off paths.
You need a cut-off path for every field in a field set. If the field sets have different sizes,
use the field set with the most fields as a guide.
Cut-off path
Y
ou can enter a meaningful name for each shutdown path.
OSSD pairs and non-safe outputs
Y
ou select the outputs that the shutdown path should switch.
7.12.6 Field Sets
Field Sets
T
he field sets that have been created are shown in the area Field sets on the right.
You use drag-and-drop to assign a field set to a monitoring case. The fields in a field set
are arranged in the monitoring case as they were drawn in the field editor.
You can cancel the assignment by dragging a field set from a monitoring case onto the
trash can symbol.
Defined cut-off behavior
In a monit
oring case, you can assign a defined cut-off behavior to a cut-off path instead
of a field:
•
Always OFF: If the monitoring case becomes active, the cut-off path is always in the
OFF state.
•
Always ON: If the monitoring case becomes active, the cut-off path is in the ON
state.
If you have not assigned fields to certain cells in a monitoring case table, Safety
Designer assigns the Always OFF function to these cells.
