5.8
Distance from walls
The edges of the safety zone must have a distance of 40 mm to walls or fixed objects on all
sides.
With this value, the function of the safety laser scanner is ensured. Depending on the re-
flective conditions of the walls or objects, higher allowances may be necessary (see
tance to intense light sources and to reflective surfaces [
).
INFORMATION
Used value of the teach-in function for the distance to the walls
The PSENscan Configurator teach-in function uses a value of 100 mm.

Planning of safety and warning zones and zone sets
}
Specify the location and the size of the safety zone and the warning zone in accordance
with the safety assessment.
}
Specify in what situations the switching operation of the zone sets are to take place.
5.10
Switchover time with zone selection
The zone selection is done by digital signals that are controlled by the control system. For
the changeover process a maximum switchover time (input delay in PSENscan Configur-
ator) is defined. For this time, non-permitted signals may be present at the entrances to the
zone selection. After the switchover time has elapsed, a valid code for a zone must be
present at the inputs for zone selection. The switchover time can be adjusted in increments
of 30 ms, and it must be adapted to the performance of the control system.
Select the time where the control system can switch an input in a defined way.
5.11
Determining the moment of switchover
WARNING!
Risk of injury due to loss of the safety function by switching the monit-
oring too late
Switching the monitoring of zone sets too late results in the loss of the
safety function. There may be people in the safety zone before switching.
– Use switching of monitoring in time or overlapping zone sets to en-
sure that no person is in the safety zone when this area changes to a
danger zone.
