Configuration of the S3000 with restart interlock
Do not confuse the restart interlock with the starting interlock on the machine. The starting
interlock prevents the machine starting after switching on. The restart interlock prevents
the machine starting again after an error or a protective field infringement.
The OSSDs on the S3000 switch to the OFF state to initiate a machine  or vehicle stop
as soon as there is an object in the protective field . They do not switch to the ON state
, even if there is no longer an object in the protective field. The OSSDs only switch to the
ON state if the operator operates the control switch for restart or reset.
WARNING
Place the control switch for restart or reset outside the hazardous area in a place
where it can clearly be seen from the hazardous area!
Place the control switch for restart or reset outside the hazardous area such that it cannot
be operated by a person in the hazardous area. Ensure that the person who operates the
control switch has a full view of the hazardous area.
 You will find examples on the connection of the internal restart interlock in section 7.5
“Connection diagrams” on page 111.
 If you do not use the internal restart interlock, leave the inputs disconnected (see
section 6.1.1 “Pin assignments of the I/O modules” on page 97).
Reset
The reset function is often also called “preparation for restart”. In these operating
instructions the term reset is used.
If you want to activate the restart interlock on the S3000 (internal) and also a restart
interlock on the machine (external), then each restart interlock has its own control switch.
After operating the control switch for the internal restart interlock (with protective field
unoccupied) …
 the S3000 switches its OSSDs to the ON state.
 the LED  on the safety laser scanner illuminates green.
The external restart interlock prevents the machine from restarting. After resetting the
S3000 the operator must press the control switch to restart the machine controller.
WARNING
Ensure that the correct sequence is followed!
The controller must be realized such that the machine only restarts if the S3000 is first
reset and then the control switch for restarting the machine controller is operated.
