Important information
DANGER
H
azard due to unexpected starting of the machine
If the protective field can be exited in the direction of the hazardous point, e.g., to areas
that are unprotected due to the method of mounting or the near range of the safety
laser scanner, the machine could restart while a person is in the hazardous area.
b
It is imperative that you configure the safety laser scanner with restart interlock if
the protective field can be exited in the direction of the hazardous point or if a per‐
son cannot be detected by the safety laser scanner at every point in the hazardous
area.
Configuration of the safety laser scanner without restart interlock
If t
here is an object in the protective field, the safety laser scanner signals Protective field
interrupted. This state is canceled again when there is no longer an object in the active
protective field.
This configuration is only allowed under one of the following conditions:
•
If an external restart interlock is implemented on the machine controller.
•
If the protective field cannot be exited in the direction of the hazardous point and
if people can be detected by the safety laser scanner at every point in the haz‐
ardous area.
Restart delay for mobile application
In mobile applic
ations, you can configure a restart delay from 2 to 60 seconds on the
device. The Protective field interrupted signal is canceled if there is no object in the protec‐
tive field for the specified period of time.
This configuration is only allowed If the protective field cannot be exited in the direction
of the hazardous point and if a person can be detected by the safety laser scanner at
every point in the hazardous area.
Configuration of the safety laser scanner with restart interlock
Figure 60: Schematic representation of operation with restart interlock
NOTE
Do not confuse the restart interlock with the start interlock on the machine. The start
interlock prevents the machine from starting after switching on. The restart interlock
prevents the machine from starting again after a fault or an interruption in the protec‐
tive field.
The safety laser scanner signals Pr
otective field interrupted to initiate a machine 1 or
vehicle stop as soon as there is an object in the protective field 2. The signal remains
active 3, even if there is no longer an object in the protective field. The signal is only
canceled once the operator activates the control switch for restart or reset.
