8.1 Automatic operation
If the safety light grids are used in the automatic mode, monitored start is not
possible�
The safety light grids automatically return to operation with clear protected area,
the outputs (OSSDs) are activated�
Verify if this is compatible with the risk analysis of your machine�
In the automatic mode the OSSD1 and OSSD2 outputs follow the status of the
safety light grids:
Protected area clear
Outputs = active logic "1"
Protected area interrupted
Outputs = deactivated logic "0"
8.2 Manual operation
Operation in the manual mode (Start / Restart) is always necessary when passage
to a hazardous area is to be monitored (persons can be present in the hazardous
area after accessing the protected area without being detected)�
The start / restart button has to be outside the hazardous area� It has to be
installed so that the hazardous area and access can be clearly seen� It must not
be possible to activate the start / restart button from within the hazardous area�
In the manual mode the safety light grids comply with the function as "trip
device" to IEC 61496� Non-compliance with this standard can lead to a
hazard for people�
The OSSD1 and OSSD2 safety outputs are activated when the protected area
is clear and the restart command is entered via a start button or via an input on
the restart pin� In the operating mode "Manually without monitoring" the restart
is carried out via pin 6, in the operating mode "Manually with monitoring of the
feedback contacts" via pin 5�
If the safety light grids are activated by a person or an object, a restart command
(24 V on pin 5 or 6) has to be released� Pulse duration > 400 ms�
