WARNING
The presence of a person between the protective device and machine table must
ALWAYS be detected. Therefore the distance between the switching point of the
protective device and the machine table (at a height of 750 mm) must not exceed
75 mm.
The same applies if a danger point is guarded with a light curtain that is mounted
horizontally or inclined up to 30°, and the end of the protective field points toward the
machine.
WARNING
The total response time of a host/guest configuration is the total of the response times
of the host receiver and the guest receiver. The safety distance must be configured in
accordance with the calculated values.
