Configuration with Restart Interlock
The OSSDs on the SafeZone Mini device change to the OFF state to initiate a
machine (1 in
) or vehicle stop as soon as there is an object in the
protective field (2 in
). They do not change to the ON state (3 in
), even if there is no longer an object in the protective field. The
OSSDs only change to the ON state if the operator operates the control switch
for restart or reset.
Figure 8 - Schematic Outline of the Operation with Restart Interlock
ATTENTION:
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. Confirm that
the person who operates the control switch has a full view of the hazardous
area.
IMPORTANT
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.
TIP
Examples of the connection of internal restart interlocks can be found in
Connection Diagrams on page 66
.
If you do not use the internal restart interlock, then do not configure any of
the universal I/Os as an input for resetting (see
).
