4.2 Access protection (Stationary Horizontal application with Dual
Protection zone)
In this kind of application, SE2L is mounted horizontally to simultaneously protect two hazardous areas
(Figure 4-4). Protection zones are configured around the hazardous area to prevent the entry of human
beings or object. Warning zone cannot be configuration in dual protection mode. Any objects or human
beings detected in the protection zones will switch the respective OSSD signal to OFF state from ON-state.
In this configuration it is possible to protect two equipments using a single SE2L.
The safety distance for this application is shown in figure 4-1.

4.3 Access protection (Vertical application- whole body detection)
SE2L can be used as a protective shield by mounting it vertically (Figure 4-5). Application shown in the
figure is generally used in preventing the access to hazardous area. When an object or human enter the
passage, OSSD signal will switch from ON-state to OFF-state.
In this configuration, SE2L detects objects or human beings in vertical plane. It is not possible to detect an
object or human being at the front or back side of the detection plane. Therefore, caution should be taken
while setting the distance between the detection plane and hazardous area. Configure the shortest response
time of SE2L not exceeding 90ms, Always use reference monitoring function in such applications to detect
the displacement of fences and SE2L which may expose the hazardous area. OSSD signal will switch to OFF
state when the position of reference is changed. The safety distance for this application is shown in figure
4-6 and 4-7.
