Figure 26: Object monitoring floating blanking
• The maximum object speed is 0.2 m/s.
• Both synchronization beams must not be covered by the objects.
• There must be a distance of at least 3 beams between two hidden areas.
• The number of hidden areas is limited to 3.
• The objects must not leave the safety field (“monitored blanking”).
• Hidden areas are monitored. Beams must not be detected in this area (“monitored blanking”). I.e. they
must always be covered by the blanking object. If a hidden beam is uncovered, the receiver enters error
state.
• The hidden areas can be taught-in on the receiver of the ESPE or via IO-Link.
• During the teach-in process, objects in the safety field should carry out the movements they would carry out
during operation.
