4. Application examples of SE2L
The section describes some application examples of SE2L and safety distance calculation in the
respective application. When using the SE2L as protective equipment, guidelines below should be taken into
account.

Hazard should be identified and risk assessment should be carried out.

SE2L should not be used for finger protection.

Working environment should be within the specification of SE2L.

Safety distance must be determined in accordance to ISO 13855 and IEC 61496-3.
4.1 Access protection (Horizontal application Stationary Protection zone 1)
In this kind of application, SE2L is mounted horizontally to protect the hazardous area (Figure 4-1).
The protection zone is configured around the hazardous area to prevent the entry of human beings or object.
Warning zone 1 and Warning zone 2 are configured surrounding the protection zone. Warning zones are used
for alerting human beings or object from approaching the protection zone and preventing unnecessary stops
of the protected machine. Any objects or human beings detected in the protection zone will cause the OSSD
signal to switch to OFF-state from ON-state. Any objects and/or human beings detected in the warning zones
will cause the warning signal to switch from ON-state to OFF-state. The safety distance for this application
is shown in figure 4-2 and 4-3.
