Configurable functions
You can configure the external device monitoring in the CDS.
You will find examples on the connection of the external device monitoring in section 7.3
“Connection diagrams” on page 92.
If you do not use the external device monitoring function, leave the inputs disconnected
(see section 6.1.1 “Pin assignment on the system plug” on page 82).
4.7 Restart
You can configure the restart behavior of the S300 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 S300 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 S300!
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 S300 (see section 5.5 “Methods of preventing unpro-
tected areas” on page 69).
Restart behavior on the integration of the S300 into a Flexi Soft safety controller
The effectiveness of a restart interlock/delay configured in the S300 is dependent on the
integration of the EFI status information from the S300 in the logic of the Flexi Soft safety
controller.
The internal restart interlock/delay acts on the OSSD of the S300. If the status informa-
tion on the OSSDs is used in the Flexi Soft safety controller, then 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 controller (see sec-
tion 12.5 “EFI status information and control commands” on page 129). In this case you
must realize a restart interlock/delay in the Flexi Soft safety controller.
Configuration of the S300 without restart interlock
After the OSSDs on the S300 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 S300 at every point in the hazardous area!
Restart delay for mobile applications
In mobile applications you can configure a restart delay from 2 to 60 seconds on the
S300. The OSSDs on the S300 switch to the ON state if there is no object in the protective
field for the duration given.
