Safety Light Array

5.3.0.8 Calculating Safety Clearance

Safety clearance is calculated with the same method used for a Light Array with full resolution.

5.4 Cascading

Neighboring danger zones can be secured by means of cascading. The fact that both safety fields act upon
a single common safety output is an important advantage which facilitates connection to the machine.

If the

Cascading function is combined with the operation mode Fix Blanking or Reduced Resolution, first configure
the respective operation mode, then activate the function.

5.4.1 Principle

By interconnecting several receivers, they can be linked such that they all act upon a single safety output.

• The Safety Light Array with the same number of beams may not be cascaded with each other.
• Response time is increased by 1 ms per additional receiver.

• It is not advisable to cascade more than 5 devices.

DANGER!

A minimum clearance of 2 m between Safety Light Arrays must be maintained in order to prevent
interactive influence amongst the utilized light curtains (see section 3.4). Even if interactive
influence occurs, system safety is nevertheless maintained in any event.

•

In the operation mode „cascading“ the Safety Light Array have to be encoded.
