ou can configure the restart behavior of the S3000 as follows:
without restart interlock
with restart delay
with restart interlock
You can configure the type of restart in the CDS.
WARNING
It is imperative that you configure the S3000 with restart interlock if the protective
field can be left to approach the hazardous point or if a person cannot be detected at
every point in the hazardous area for the S3000!
During the assessment, pay attention to whether the protective field can be left in the
direction of the hazardous point, to areas that are unprotected due to the mounting and
the unprotected near range of the S3000 (see section 5.4.4 “Methods of preventing
unprotected areas” on page 82).
Restart behavior on the integration of the S3000 into a Flexi Soft safety controller
The effectiveness of a restart interlock/delay configured in the S3000 is dependent on the
integration of the EFI status information from the S3000 in the logic of the Flexi Soft safety
controller:
The internal restart interlock/delay acts on the OSSD of the S3000. If the status infor-
mation on the OSSDs is used in the Flexi Soft safety controller, then the restart inter-
lock/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 controller (see
section 12.5 “EFI status information and control commands” on page 156). In this case
you must realize a restart interlock/delay in the Flexi Soft safety controller.
Configuration of the S3000 without restart interlock
After the OSSDs on the S3000 have been switched to the OFF state due to an object in the
protective field, the OSSDs are re-enabled again immediately when there is no longer an
object in the active protective field.
This configuration is only allowed …
if an external restart interlock is realized on the machine controller
or
if the protective field cannot be left in the direction of the hazardous point and if people
can be detected by the at every point in the hazardous areaS3000!
Restart delay for mobile applications
In mobile applications you can configure a restart delay from 2 to 60 seconds on the
S3000. The OSSDs on the S3000 switch to the ON state if there is no object in the
protective field for the duration given.
This configuration is only allowed if the protective field cannot be left in the direction of the
hazardous point and if a person can be detected at every point in the hazardous area by
the S3000!
