Product description
IN4000 Standard series safety switches can be cas-
caded (see section 5.2 "Series circuit of the inductive
safety switches" on page 82).
Information on the connection is also to be found in
the operating instructions for the safety controller
used (e.g. Flexi Classic or Flexi Soft).
3.3 Enable zone and safe switch off
distance
Near range
Sensor
The output of the safety switch is only enabled on
activation within the enable zone. Outside the enable
zone, that is also in the near range, the output
remains switched off.
After activation in the near range, either the power
supply must be interrupted or the actuating element
must be placed at the safe switch off distance for
more than 2 s before enable is possible again.
The enable zone is dependent on the type of safety
switch and the material and shape of the actuating
element. The use of different actuating elements
(material, shape) will result in different enable zones.
