A restart interlock must be implemented depending on applicable national regulations
or required reliability of the safety function.
b
Make sure that a restart interlock is implemented.
Requirements for the electrical control of the machine
Bo
th outputs are short-circuit protected to 24 V DC and 0 V. When the protective field
is clear, the OSSDs are in the ON state. When a switch-off condition is present (e.g.,
interruption in the light path), the OSSDs are in the OFF state. In the event of a device
fault, at least one OSSD is in the OFF state.
The protective device complies with the rules for electromagnetic compatibility (EMC)
for the industrial sector (Radio Safety Class A).
NOTE
Usin
g the device in residential areas may cause radio interference. The operating entity
is responsible for taking appropriate measures (e.g., shielding).
The following requirements are met:
•
T
he external voltage supply of the safety light curtain must be capable of bridging
a brief power failure of 20 ms as specified in IEC 60204-1.
•
The power supply unit must ensure safe isolation according to IEC 61140
(SELV/PELV). Suitable power supply units are available as accessories from SICK.

4.4.1 Restart interlock
Overview
T
he restart interlock prevents the machine from automatically starting up, for example
after a protective device has responded while the machine is operating or after chang‐
ing the machine’s operating mode.
Depending on the regulations which apply at the place of installation, a restart interlock
may be required.
The safety light curtain has an internal restart interlock.
Important information
DANGER
H
azard due to unexpected starting of the machine
The machine may not restart if the OSSDs switch to the ON state once the reset
pushbutton has been pressed. The control must ensure that the machine only restarts
if the machine start button is also pressed after the reset pushbutton.
b
Make sure that the machine can only restart once the reset pushbutton and start
button have been pressed in the specified order.
Principle of operation
Be
fore the machine can be restarted, the operator must reset the restart interlock.
