Important information
DANGER
Hazard 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.
Restart behavior when the safety laser scanner is integrated into a Flexi Soft safety
controller
The effectiveness of a restart interlock/delay configured in the safety laser scanner
depends on the integration of the EFI status information from the safety laser scanner
in the logic of the Flexi Soft safety controller.
•
The internal restart interlock/delay acts on the OSSDs on the safety laser scan‐
ner. If the status information on the OSSDs is used in the Flexi Soft safety con‐
troller, the restart interlock/delay also acts on the Flexi Soft safety controller.
•
If the status information on the protective fields is used in the Flexi Soft safety
controller, the restart interlock/delay does not affect the Flexi Soft safety con‐
troller. In this case, a restart interlock/delay must be implemented in the Flexi Soft
safety controller.
Configuration of the safety laser scanner without restart interlock
If there is an object in the protective field, the OSSDs on the safety laser scanner switch
to the OFF state. The OSSDs are re-enabled again immediately 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 applications, you can configure a restart delay from 2 to 60 seconds on the
device. The OSSDs on the device switch to the ON state if there is no object in the pro‐
tective 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.
